Ford Focus Problems

Ford replaced the Mark 1 Focus with the Mark 2 in June 2005, so interchangeability would depend on the build date of the 2005 Focus you have. While the Mark 1 and Mark 2 Focus both offered a two-litre four-cylinder engine (among others) the two engines were from different engine families. The earlier car used a member of the Zetec family, while the Mark 2 Focus two litre was from the Duratec family.

So, unless both Focuses are Mark 2 cars, there's very little chance of sharing things like intake manifolds, even if the spark plugs and ignition systems could be swapped between Mark 1 and Mark 2 cars.

They might both be Ford Focuses, but they're a couple of generations apart meaning that they are not only physically different, they also used different transmissions to each other. Even if, by some miracle, the older gearbox would bolt to the newer engine, the car still wouldn't have the correct electronics to make the transmission work properly.

Even if the transmission in question was a manual which requires much less in the way of electronic control, the unit in the 2008 Focus was a five-speed, while the later car used a completely different six-speed. Even things like the clutch and flywheel would be incompatible. You'd probably even find the gear-shifter for each transmission enters the cabin in a physically different spot, meaning the interior trim would no longer fit.

Ford Focus Bluetooth wasn’t a reality until the new model that arrived in 2011. But at the point, it was standard on every trim level (including voice command) and was many people’s first taste of the tech. Prompting a lot of online questions along the lines of how to connect Bluetooth to Ford Focus?’ It’s actually pretty easy. That said, the best of these earlier systems used Ford’s SYNC tech which was introduced on Focuses built from August 2012 onwards.

Bluetooth Ford Focus pairing starts with switching on the Bluetooth on your phone and making the device discoverable. Then press the Phone button on the car’s menu system and follow the prompt to Add A Device. You should then be able to select SYNC from your phone’s list of available devices, enter the security code displayed on the car’s screen and your Ford Focus Bluetooth pairing is done.

From there, you can make and receive calls, view text messages and stream music, all via the voice command system.

Don't be so sure your car isn't covered by Ford's factory warranty. If it was delivered brand-new (as opposed to built) after May 1 of that year, it's subject to a five-year/unlimited kilometre warranty, so would still be covered. However, if it was delivered before that date, the warranty would have been three years or 100,000km which has now run out. Even so, given the kilometres and the service record, I think you'd be a good case to have Ford come to the party with some help on the repairs on a pro-rata basis.

From what you've told me, I'm guessing you've only dealt with Ford at the dealership level. Go over their heads and talk directly with Ford HQ's customer service department. A quote for $3500 just to examine the car is, on the surface of it, absurd and should be treated with suspicion. Any competent mechanic should be able to diagnose what's going on and whether or not the engine needs to be replaced. My advice here would be to have the car inspected by your state motoring club (the RACV in Victoria) which can give a cost-effective and independent report on the car's condition (and won't cost anything like $3500). This is also excellent legal and evidential back-up if the case does progress to VCAT.

On the face of it, 62,000km is not a reasonable lifespan for a fully serviced engine and the manufacturer should shoulder at least some of the cost of putting it right. Your last resort should be to contact the ACCC and talk to that body regarding your rights under Australia Consumer Law which covers goods (including cars) that are not built to a reasonable level of quality or are unfit for service. A failed engine at such mileage may well fall into that category.

Just for starters, the ZX4 is a four-door sedan, while the ZX3 body is the three-door hatchback. At the very least, that will mean differences in the wiring loom as regards door-courtesy and boot/tailgate lights. Cars will have different wiring looms depending on their transmission, too, so even if the engine is the same in both cars, the loom might not be.

Then there's the more basic question of whether they're actually the same model of Ford Focus. Ford Australia switched to the all-new second-gen Focus in April 2005, and if your 2005 Focus is that newer version, the wiring will not be compatible with the 2001 model. But even if they're from the same generation of Focus, swapping a wiring loom from one car to another involves many, many hours of work.

As both these model-years concern the same series of Focus, there would definitely be some interchangeability. Body panels should interchange readily (provided you don't try to fit the hatchback from a five-door to the boot of a four-door) and many interior fittings would also be able to be swapped (provided the interior colour and trim materials of the two cars matched).

Mechanically, however, you need to be a bit more careful. Obviously, there would be major differences between the driveline of the diesel version and the more common petrol model, but there will likely be differences to driveshafts and all sorts of components when you compare a manual Focus to an automatic one. Different trim levels can also cause interchangeability problems in terms of a base-model car not having the electrical wiring to support the convenience equipment of the upmarket version. Things like the power windows in the rear of a Focus Ghia, for instance, will cause problems in the base-model CL which relied on manual rear windows.

Luckily, your car is in the clear, and the LW Model Focus was the one with the hugely problematic dual-clutch transmission. In fact, these gearboxes were more or less ticking time bombs and more than half of them suffered – sometimes multiple – failures requiring replacement units. Ford was taken to task by the ACCC over its handling of the whole thing and was forced to quickly revise the Fiesta, Ecosport and Focus ranges. Which is why your car, the LZ model, has a turbocharged 1.5-litre engine and a conventional automatic transmission which is not only a better thing to drive, but also vastly less likely to fail prematurely and expensively.

Ford made the switch to the LZ model in 2015, largely as a response to the fearful reputation for transmission failures the LW model had gained. Our advice to anybody shopping for a Ford Focus (or Fiesta or Ecosport) is to absolutely avoid any example with the dual-clutch gearbox. Its demise will be a question of when, not if.

It will all depend on when in 2005 the Focus in question was built. Ford changed from the Mk1 Focus (LR model) to the all-new Mk2 Focus (LS model) in April of that year, so an early-build car will not be the same as the 2009 model, although a later-2005 one might be.

These two versions of the Focus were built on different wheelbases and platforms, so there may not be too much interchangeability. Certainly the bodies were quite different, so panels and interiors won't be interchangeable at all. Even the steering systems were different model-to-model. The Mk1 used conventional power-steering, while the Mk 2 switched to electro-hydraulic power-steering.

The compliance plate under the bonnet will tell you all you need to know about the car's build date. Visually, the earlier car had a much more angular style at the front with almost triangular headlights, while the later car was more upright and conventional looking.

Perhaps you've been lucky and simply bought a freakish Focus without any DCT Powershift transmission problems. But when more than half the small Fords sold in Australia fitted with that transmission  experiencing either single or multiple failures, I'm afraid the odds are stacked against you in the longer term. It seems there are two types of Focus Powershift transmissions: Those that have failed, and; those that will fail at some stage.

The price you paid is probably about where the market is now, but this is a car we can't recommend at any price.

You’re talking about two distinct models of the Ford Focus, so if there’s any interchangeability it won’t be much. Perhaps there would be some mechanical parts in terms of the engine, but the 2007 model was a physically larger can than the original (2003) so even things like the suspension units and brakes are unlikely to be interchangeable.

As for body panels and interior fittings, I doubt there’d be any interchangeability at all. The later car had different panels and the interiors were also completely different. Changes to styling also mean that headlights, tail-lights, glass and even detail things like door handles would not be interchangeable.
