BMW Problems

The BMW 7-Series launched in 2009 was a return to the finer things in life after previous models had diverted down a side road on which performance was a premium.The F01 and its long wheelbase F02 sibling echoed the old ethos of elegance and driving enjoyment that marked the old BMW flagship out from its great rival from Stuttgart.With its carefully crafted lines and timeless proportions the new 7- Series returned to the elegance of old; it was certainly less confronting then the earlier model. Inside, it was a mix of classic style and modern practicality. It was quiet, comfortable, refined, and the driver was surrounded with all the mod cons, including BMW's iDrive system, Bluetooth, voice commands, and useful systems like active cruise control and a heads- up speedo display as well as all the expected features.There was plenty of choice of engines, from the 3.0-litre turbo- diesel, through the twin-turbo six, the twin-turbo V8 and the mighty V12. All were turbocharged, BMW's thinking being that a turbocharged engine could be economical and environmentally friendly when tootling along, but would still have plenty of punch when you planted your right foot. The six-speed auto that is mated to all but the V12, which has an eight-speed auto, has tough shifting and adaptive shift programming.Less visible were the stiffer, but lighter body and the lightweight aluminium suspension. More obvious were features like night vision, lane-change warnings, heads-up display, improved run-flat tyres and variable light distribution.IN THE SHOPThe F01/F02 models are still relatively new out of the box, most will have done less than 50,000 km, and so failures and issues are few and far between. While solidly built BMWs are not immune to problems, particularly as they age, but it's fair to think the 7-Series will be relatively trouble-free for another 100,000 km or so. Servicing is important to keep on top of any problems that do crop up, so check for a service record for proof of regular oil changes.IN A CRASHThere is no ANCAP rating for the 7-Series, but it's fair to assume it would come in at the top end of the five-star scale if it were tested. With dual front, side and curtain airbags, ABS brakes and electronic stability control it has the best of everything in the safety world.UNDER THE PUMPThe big Beemer is a heavyweight of the auto world and that has to be reflected in the fuel consumption. The turbo-diesel is the one to go for if fuel economy is your priority. It returns a claimed average of 6.8 L/100 km, impressive for such a big car. The petrol options aren't as thrifty when it comes to fuel economy, the twin-turbo six averages 9.9 L/100 km, the twin-turbo V8 averages 11.4 L/100 km, and the V12 averaged 13.0 L/100 km. All petrol engines require premium unleaded.AT A GLANCEPrice new: $198,800 to $386,000Engine: 3.0-litre 6-cylinder turbo-diesel, 180 kW/540m Nm; 3.0-litre turbocharged 6-cylinder, 240 kW/450 Nm; 4.4-litre turbocharged V8, 300 kW/600 Nm; 6.0-litre turbocharged V12, 400 kW/750 Nm.Transmission: 6-speed auto, 8-speed auto (V12); RWDEconomy: 6.8 L/100 km (730d), 9.9 L/100 km (740i), 11.4 L/100 km (750i), 13.0 L/100 km (760i)Body: 4-door sedan (LWB), 4-door sedan (SWB)Variants: 730d, 740i, 740Li, 750i, 750Li, 760LiSafety: N/A.VERDICTA return to greatness after the 7-Series had lost its way.

The BMW Z3 and Z4 are genuine roadsters, not simply convertibles. The difference being that roadsters are strictly two-seaters and the seats are set well back, almost to the rear axle. The resulting very long nose and a stubby tail mean the BMW Z-cars have a no-nonsense purposeful appearance.The BMW Z3 was launched in Australia way back in January 1997. It was BMW’s answer to the astonishing success of the Mazda MX-5, a car that reinvented the open-top car many thought had gone forever. Despite its different name, the BMW Z4 is really the second-generation Z3, it was given the new title to match the new naming system which sees the sporty variants getting even numbers.The Z series models were initially designed for the USA so in the early editions are rather American in their makeup for keen Aussie drivers. In particular, their handling was softer than usual for a BMW, though far from soft in absolute terms. When the Z3 also became a hit in many other countries, including Australia, the handling became full-on sport with the introduction of the Z4.The first Australian imports of the BMW Z4 reached us downunder in July 2003. Handling of the Z4 is exceptionally good with excellent chassis balance thanks to the setback position of the engine. Naturally rear wheel drive gives you proper throttle control. Some may feel the ride is on the firm side, but true drivers will be more than willing to overlooks this.Perhaps take along your regular passenger and get their feelings for the car on roughish roads. Though the little BMW began life with a 1.9-litre four-cylinder engine, the German marque is famed for its six-cylinder engines and these were soon squeezed under the long bonnet and almost immediately became the powerplant of choice in almost all cars.In June 1999 imports of the 1.9-litre four had ceased in Australia and all used a sweet little 2.0-litre straight-six. The big gun engine in the Z3 is the 3.0-litre six-cylinder. Performance from the smaller engines is nothing to get excited about, but the free-revving nature, and great exhaust note, makes them feel faster than they really are – and isn’t that what counts?BMW Z4s have a 2.5 or 3.0-litre straight-six from their 2003 introduction until the company started to get into the small-capacity turbocharged field with blown four-cylinder engines. Some sixes remained alongside the turbo-petrol fours until 2012, when they were replaced by big-boost turbo fours. Some miss the demise of the straight-six turbo engines – ourselves included – so if you really love them it might be time to invest in the last of the line.A special engine is used in the Z4 33i models. A 3.0-litre twin-turbo six, it gives huge amounts of forward thrust and is a delight for the revheads to punt along. Manual and automatic transmission are offered in most cars and the auto isn’t as slow and irritating as in some sports models. Our choice is still the DIY shifter, though.Manuals have six gear ratios. The autos increased in the number of gears, beginning with just four speeds in 1997 and advancing to no fewer than eight in 2012, with five and six speeds being sold along the timeline. The BMW dealer network is well established in Australia and is known for its high quality of technical training.Electronic diagnosis of problems is highly refined as BMW was a leader in this field. The technician plugs in your car and it is then connected to a large computer in Germany where it is quizzed not only on current problems but even in intermittent troubles that aren’t actually present in the car at the time it was driven into the workshop. Clever stuff.This high-tech diagnoses and servicing is just one reason it makes a lot of sense to buy a used Z3 or Z4 that has always been serviced by an official BMW dealer. Spare parts aren't outrageously expensive for a car in this class, but may prove to be a factor in your decision as to whether to buy an older Z4 rather than a cheaper convertible from a lower-cost maker.Insurance may be expensive if the driver is young and/or inexperienced. Surprisingly there is seldom a big increase in premiums for the high-performance models.WHAT TO LOOK FORCarry out your own pre-purchase inspection to the best of your ability. Once it has passed your tests call your BMW dealer, or at least a qualified mechanic with knowledge of the marque. Lift the carpets for signs of dampness or even rust if the car has been caught out in the rain in a big way. It’s best to ask permission from the seller before doing this as technically it’s dismantling the car and that is often frowned upon.Check for previous crash repairs by looking for signs of paint overspray, panels with a slight waviness in their finish and for colours that don't match exactly from one panel to the next. Make sure the engine starts virtually instantly, idles smoothly within a second or so of startup and pulls without hesitation even when completely cold.CAR BUYING TIPSome sports cars are ‘fanged’ on a daily basis, others never get past the mid-range marks on the tacho. No marks for guessing which is the better bet as a used car. 

Even in its smallest model, the 1 Series, BMW has stuck to its guns in providing pure driving pleasure. Witness the use of rear-wheel drive to provide the sort of chassis balance that keen drivers just love.The downside of RWD is that there isn’t a lot of room inside a BMW 1 Series because of the long engine bay needed to house straight-six engines, space for a driveshaft under the floor, and a differential under the back floor.  Having said that, the cabin has good legroom in the front seats, though some may find foot-width is restricted.There's not a lot of passenger space in the back unless the front occupants are willing and able to give up a fair bit of their legroom. By the way, BMW does sell a front-wheel-drive car – it’s called the Mini. However, it’s not exactly spacious in the back seat either.When launched in Australia in October 2004, BMW 1 Series came only as a five-door hatch. A smart two-door coupe and a pretty little soft-top convertible were added to the range in May 2008. BMW 1 Series’ styling in hatchback format gives it a tail end treatment that's almost wagon like. So while the boot is relatively shallow due to the aforementioned differential being under it, there reasonable overall volume.Most of these small BMWs are powered by a four-cylinder 2.0-litre engine.The coupe and convertible aren’t as useful in their luggage spaces as the five-door hatch, but that’s hardly unusual in the sporty market. As always, try for yourself to see how the brilliant baby Bimmer meets your individual needs in people / luggage carrying.BMW 1 Series comes with a staggering choice of powerplants. In petrol format, these range from 1.6-litre and four cylinders all the way to 3.0 litres with six cylinders. Some of the sixes have twin turbochargers, others don’t have a blower at all. The twin-turbo engine is a superb unit and takes the 300 horsepower, 224 kilowatt BMW 135i to close to the famed BMW M3 in its performance.The 1 Series M Coupe, with even more power from its twin-turbo six than the standard turbo-petrol models, provides excellent performance and many are saying it could have been called the M1 to join the M3 and M5 in the high-performance lineup. However, the M1 tag was used on a BMW supercar model in the late 1970s and the company chose not to use it for the new hot coupe.Most of these small BMWs are powered by a four-cylinder 2.0-litre engine. Even the so-called 118i has a 2.0-litre capacity, though others actually do displace 2.0 litres. To further add to the confusion, the 125i engine actually has a displacement of 3.0 litres (it's the six-cylinder unit without turbochargers).Transmission choices are generally six-speed manual or six-speed automatic.An impressive 2.0-litre turbo-diesel engine became part of the lineup, in BMW 120d format, from May 2006. The grunt of the modern BMW diesels is great, but they miss out on the virtually instantaneous throttle response provided by non-turbo powerplants so many drivers aren’t keen on them.Improbably as it would have seemed a decade back, the 2.0-litre turbo-diesel is even used in BMW 1 Series coupes and convertibles. It is tuned for greater power, so has the title of 123d, rather than 120d. Transmission choices are generally six-speed manual or six-speed automatic. Some of the smaller-engined, lower cost models were sold with a five-speed manual in their early days.BMW manual gearboxes are a joy to use, with slick changes through the well-chosen ratios. This is another benefit of the use or rear-wheel drive as the gearbox is close to the lever, not way out near one of the front wheels as in a front-drive car. Unless you do a lot of hard commuting we suggest the pleasure of the manual should be yours.BMW is long established in Australia and there are dealers in all metropolitan areas, as well as in major country centres. However, if you do travel into semi-remote areas you may have trouble finding either a dealer or a mechanic experienced on the marque.Ideally a BMW should be serviced and repaired by an authorised dealer as these are complex cars with a lot of electronic components. The car can be connected to a computer to assist in fault diagnosis. There are some mechanics with formal BMW training and who now operate as independent specialists. They generally have a high reputation.A 1 Series with a written service record stretching back to day one will generally fetch a higher price on the used market. Smart buyers of second-hand models will keep up this record ad infinitum. Insurance charges are high for a small car – but not too bad when you consider the complexity and quality of the BMW's body and the fact that you're buying an image machine, not simply a car.WHAT TO LOOK FORCheck the back seat and boot trim in case some large items (such as people!) have been squeezed into a space that wasn’t adequate for them. Many 1 Series live in suburban areas so could have had the odd bump or scratch. Look for signs of crash repairs such as mismatched paint, paint overspray and ripples in the panels.A magnet will tell you if the material under the repaired area is metal – or plastic filler that has been inserted to try and fool the innocent. Engine repairs can be expensive so make sure they start within moments of turning the key. Preferably arrange to do this with the engine stone cold after an overnight stop.During your test drive feel for any hesitation under acceleration and look for oily smoke from the exhaust when the engine is worked hard. Make sure manual gearchanges are quiet and ultra-smooth. Fast changes from third to second gears are usually the first to show problems.CAR BUYING TIPCars designed to be driven hard and fast seldom are. Don’t we live in a strange world? So if you do come across one that’s been driven the way its makers intended it may be best to look elsewhere.

BMW has been stung by a 1.3 million vehicle global recall. BMW is recalling all models of the previous generation 5-Series and 6-Series, built from 2003 to 2010, because of a faulty battery cable cover.In a worst-case scenario, the car could catch fire. Spokesman for BMW Australia, Piers Scott, says exactly 10,000 cars are affected in this country. "We are contacting all owners, via dealerships, immediately,'' he says."We haven't any reports of problems and I guess this could be seen as being overly-cautious but this is the best approach.'' Scott says issues like this reinforce cars should be serviced through authorised BMW dealerships "however, we will be alerting all service channels to capture all owners''."The problem centres on wiring that is not easily visible,'' he says. It is the second million-car recall in two years, following Toyota's massive 9-million car recall in 2009-2010 for alleged sticking accelerator pedals.BMW says no accidents or injuries have occurred because of the issue, but there is the potential that affected models may fail to start, or worse, catch fire. Owners will be sent a letter and will be asked to visit a BMW dealer for a free, 30-minute repair session.The company says in some instances, the battery cable cover - which is inside the boot - may be incorrectly mounted. It says this can result in the electrical system malfunctioning, the vehicle failing to start and, in some cases, to charring or fire.BMW last year was penalised $3 million for failing to quickly report safety defects to the US vehicle safety authority, the NHTSA. Recalls of more than 1-million vehicles are rare. The latest big recall was Toyota that in 2009-2010 recalled about 9-million Toyota and Lexus vehicles worldwide for defects associated with unintended acceleration.This year recalls have been announced by companies including General Motors which in the US is to repair problems with the steering system that could result in a loss of steering. There are no known complaints about this issue. Porsche is also recalling about 1200 911 Carrera S coupes from the 2012 model year in the US because the fuel line may become disconnected, leading to fuel loss and possible fire.TOP 10 RECALLS 

The company reports an engine oil pump problem that could lead to severe engine damage. The global recall affects 2013-model M5, M6 coupe and M6 convertibles.Luckily, the 20 Australian cars are either still on the boat from Germany or in Australia but yet to be delivered, says BMW Australia spokesman Piers Scott. “There are 20 cars affected but because these relate only to a set production period, every one of those cars is either still to be delivered or not yet in the country,'' he says."So there is not a single Australian owner or customer affected.'' BMW sent out a technical service message to dealers over the weekend. It says it found a “manufacturing defect'' in the oil pump through its quality checks. The affected models were built this year between July and September.The recalled cars are equipped a turbocharged 4.4-litre V8 engine that BMW internally calls the S63TR. BMW says that cars with the faulty pump could suddenly lose oil pressure, triggering severe engine damage. "Because of this potential, BMW and its dealers will stop delivery of all affected vehicles until the recall repair has been completed,'' BMW says in an emailed statement.The company did not say how many cars are affected. BMW has boasted that the S63TR is the most powerful engine it has built for its high-performance M division. At 412kW/680Nm, it has 10 per cent more power and torque than its previous V10 engine but has a 30 per cent reduction in fuel consumption. BMW's M5 costs $230,000 and the M6, which arrives next month, about $300,000. 

The recall, affecting about 1600 vehicles in Australia built from January 1 2007 to March 5 2010, is part of a global defect notice on 35,000 X5s in the US and Canada.BMW says a vacuum hose leading to the brake booster has the potential to bleed oil into it, damaging an internal rubber membrane and leading to the loss of power braking assistance.If that happens, the car can only be effectively braked if the driver pushes the pedal extremely hard – and with some drivers unable to exert enough pressure there is the risk of the vehicle not stopping soon enough or in a short enough distance to avoid collision.“The immediate fix is to replace the hose with a modified that eliminates the problem,” BMW spokesman Scott Croaker says. “However if oil has got into the booster, we will replace the whole booster.”The problem was discovered when overseas warranty claims increased, and Croaker says there have been no brake failure incidents reported in Australia.Owners of affected vehicles should contact their nearest BMW service centre, or call the BMW Australia Customer Service on 1800 813 299.
