Fuel pump problems with a 2007 Mercedes-Benz E200k

At the first sign of a fuel pump that has started to play up, the advice is to replace it as soon as you can. These electric pumps can start to have intermittent faults where they will not pump fast enough or not at all, and then the next time you start the car, they'll work perfectly.

Don't be fooled into thinking it's all okay, however, as the pump will progressively get worse and worse until it won't work at all. Trust us, these things do not fix themselves. And since a fuel pump will leave a modern fuel-injected car absolutely high and dry, you're way better off fixing it now (by replacing the pump) than finding yourself stuck on the side of the road in the middle of nowhere.

Questions about the GVM of a 2009 Mercedes-Benz LWB Sprinter

This is an increasingly common problem for people who carry big loads and especially for those who tow heavy trailers. In some cases, as you've discovered, it's very easy to get perilously close to the GVM limit by loading up the vehicle with whatever you're carrying. And that's the catch; the vehicle's GVM includes everything on board including passengers, fuel and whatever accessories you've added to the car, not to mention the actual payload.

Earlier this year, Queensland changed its rules regarding GVM upgrades, but you would need to speak to a specialist workshop that deals with this type of work and is familiar with the QLD regulations which may vary from other states and territories. Companies such as Pedders are qualified to carry-out GVM upgrades on some vehicles and have the engineering experience to offer a package that is certified before it's fitted to your vehicle. Whether the Sprinter's body construction has any bearing on the availability of such a kit is another thing you'd need to check with a specialist.

The problem with exceeding your car's GVM is that it makes its potentially unsafe to drive for both you and other road users. You'll also find yourself in line for a fine and your insurance company is likely to disown you in the case of a crash in an over-loaded vehicle.

Are there known problems with the 2005 Mercedes-Benz Vito?

I've heard of these vehicles racking up huge mileages, but even so, 450,000 is a lot of kilometres and the thing could be a breakdown just waiting to happen. If it's been meticulously maintained, you might get a few more years out of it, but there's every chance it could be ready to go bang in some way. Certainly, the asking price should reflect this.

This model Vito was beset by a huge raft or recalls for all sorts of things, so make sure those have been attended to., Mechanically, the most common big-ticket item was a timing chain that could wear out (often long before 450,000km had passed under its wheels). Because the timing chain in the turbo-diesel engine is at the back of the engine (the transmission side) access is fiddly and the job to replace the chain, guides and tensioners is a relatively expensive one.

What are the best van options for wheelchair modifications?

From the sounds of things, you need a vehicle that can accommodate the wheelchair as an actual seat in the car rather than having the chair folded and stored for the journey. With that in mind, a van or people-mover is by far the best best bet and the news is good, because there are plenty of choices. For a while there, people were converting Ford Falcon station-wagons for this task, but since the Falcon is no longer made, vans have become the new default vehicle to convert. Which makes plenty of sense.

There are specialist firms around that will carry out whatever conversion you require and tailor-make the ramps, lock-down points and grab-rails you need to make it work for you. Switched on companies will sit down with you and discuss your precise requirements and engineer something bespoke if necessary.

At the moment, the list of car choices is pretty long and includes the new Hyundai Staria, VW Caddy, LDV G10, VW Caravelle, Renault Kangoo, Renault Trafic, Hyundai iLoad, Mercedes-Benz V-Class, Toyota HiAce and, in case you need something really big, even the Toyota Coaster. Some of these companies are also registered as NDIS suppliers.

But don鈥檛 rule out a second-hand vehicle, either. There are websites around listing used wheelchair-accessible cars for sale. Some will be ex-taxis, but others can be relatively low-kilometre cars that might just have the exact layout you were looking for.

Is a Mercedes-Benz C220 or BMW 320d better for fuel economy?

I've used the last versions of both those models for this comparison, which means a 2019 BMW 320d and a 2021 Mercedes-Benz 220d (I'm also assuming you're comparing diesels with diesels).

As such, the BMW holds a slim on-paper advantage with an official combined fuel consumption number of 4.4 litres per 100km, compared with 4.7 litres for the Benz. In the real world, that difference is a very, very small one and means the two vehicles are more or less line-ball for fuel economy.

Real world fuel consumption has a lot more to do with your driving environment and style than it does these laboratory-produced numbers. But the official numbers are valid on the basis that both vehicles were subjected to the same strict test regime, so they do provide a direct comparison, even if you'll almost certainly never match them in real life. Both, however, will surprise you with how frugal they can be.

Are there plans for Mercedes to bring out an EV small car?

At this stage, the smallest Mercedes-Benz EV is the EQA. Although there鈥檚 a Smart EV in other parts of the world, there are no plans to introduce it here. The decision not to make an A-Class hatchback EV is in line with the rest of the world鈥檚 car-makers who are ditching conventional hatchback and sedan designs in favour of the all-conquering SUV packaging.

However, while the EQA is physically larger than your current A250, it鈥檚 probably not by as much as you might imagine. In overall length terms, the EQA is about three centimetres longer and about five centimetres wider. The big difference is that the new car is a lot taller; about 19 centimetres higher, in fact. But even then, the EQA is still a pretty compact car, and if your garage won鈥檛 accommodate those dimensions, I鈥檓 wondering how it was ever council-approved as a parking space within a building.

As for your other requirements, the EQA has a theoretical range of up to 400km and can be fast-charged. As for more charging points in public areas on highways, I鈥檓 afraid that鈥檚 one you need to talk to your local government member about, not Mercedes-Benz.

How much value do factory options add to a Mercedes?

Factory options can add to the resale price of a vehicle, but not the full amount that they cost when the car was ordered new. Which means the AMG equipment and vision package will take the vehicle closer to the higher valuation. Some options are more highly valued than others, too, and the AMG package is one of them.

As for aftermarket (or dealership-fitted) options such as ceramic paint treatment, fabric protection and tinted windows, regardless of what the seller tells you, these add very little 鈥 if anything 鈥 to the resale value.

What van should I get to build a camper van?

Mitsubishi鈥檚 L300 Express was available as a four-wheel-drive model way back in the 1980s (83 to 86) and was a very popular van to convert for camping thanks to that all-wheel-drive grip that allowed it to tackle rough roads with little problem. After 1986, a few of the later model Express 4WD vans (often badged Delica) made it into Australia as private imports, and there are a few of them around now to choose from.

The requirement to be able to stand up inside the vehicle will limit your choices a little, but popular vans like the Toyota HiAce, Ford Transit and Mercedes-Benz Vito were available in a high-roof configuration. Even though they lacked all-wheel-drive, generally rugged construction means they should cope with dirt roads pretty well. They just won鈥檛 have the grip for off-road work.

As with any second-hand commercial vehicle, try to find out what it did in its previous life. A van that has been used for hard labour might well be worn out. And don鈥檛 forget, nobody bought these things new for anything other than a working life.

If, on the other hand, you鈥檙e shipping for a brand-new van, there are plenty of options from Ford, Mercedes, Peugeot, Fiat, Toyota and more. The vast majority of them use a turbo-diesel engine so will be quite economical and many also offer an automatic transmission for ease of driving. Choose the one that suits your intended layout best in terms of side and rear doors and the ability to climb from the front seat into the van area without leaving the vehicle (some have cargo barriers that will prevent this).

I tried to buy a new set of the specified, run-flat tyres for my 2015 Mercedes-Benz C-Class C250. None will be in stock until June...

You don鈥檛 have to fit run-flat tyres to your car, but it can be a lot more convenient. A decade or so ago, it was quite common to replace run-flat tyres with more conventional tyres as the ride quality of run-flats was relatively poor. These days, that isn鈥檛 the case to the same extent, and run-flats have come a long way.

But if you can鈥檛 get them in the correct size, then you have a problem that can be solved by fitting conventional tyres of the correct size, speed rating and load rating. A tyre shop should be able to sort this out for you.

The catch, of course, is that a conventional tyre won鈥檛 get you home if it deflates for any reason (as a run-flat is designed to do). The knock-on problem there is that a car designed for run-flats will not only not have a spare tyre, it won鈥檛 even have a physical space to put one. The solution then is to find a repair kit of the type found in many cars today. This amounts to a tin of repair solution which is added to the tyre through the valve and the tyre reinflated with the attached compressor.

The transmission keeps slipping on my 2002 Mercedes-Benz C-Class. Do you know what could fix this?

If the transmission is working properly between bouts of slippage, then it鈥檚 reasonable to think that this could be an electronic problem rather than a mechanical one. By turning the ignition off and then restarting, you鈥檙e effectively resetting the computer that controls the transmission. That鈥檚 why the gearbox comes good for a period before reverting to its old tricks.

That鈥檚 on the surface, anyway, but the problem could also be within the torque converter or something intermittent inside the actual gearsets, clutches, bands or valve body that is giving the same set of symptoms.

Ultimately, this is probably going to require a trip to a transmission specialist who will be able to identify the cause more accurately. In the meantime, though, there鈥檚 something you can try that might reset the transmission more permanently. On this model Mercedes-Benz, there鈥檚 a specific transmission-reset procedure that should take the gearbox back to its original factory settings. If that鈥檚 the case, it might fix your problem, but if not, then you need to call in the experts.

The procedure starts with getting in the car, closing all the doors and turning the ignition key to the on position, but not actually starting the engine. You should have all the dashboard lights illuminated at this point. Then, press the accelerator pedal right to the floor, making sure you can feel that the kick-down d茅tente has been activated. Hold the pedal all the way down for at least 60 seconds and then, without releasing the accelerator, turn off the ignition. Don鈥檛 open the door and don鈥檛 remove the key from the ignition. Now release the accelerator and wait five minutes before starting the engine and going for a test drive.

Good luck.
