Font suspension trouble - dealer won't listen
Answered by Graham Smith · 04 Jan 2013

As the dealer has offered to recheck the car that is where you should start. It would seem that there is a fault with the strut or a bush in the suspension and the dealer can check those things. If that doesn't produce a resolution then you could approach BMW directly.

Known issues with high-mileage BMW and Mercedes?
Answered by Carsguide.com.au · 20 Nov 2015

Our experience is that older BMWs suffer problems with things like the plastic fittings on the engine, the plastic radiator tanks etc. that can add up to a sizeable sum of money when you have to replace them. One car, an older 3-Series that had done around 250,000km developed a problem with the power steering that had mechanics completely stumped. After four visits to the workshop, having replaced the steering rack, the power steering pump and many other steering parts, it was finally found that the fault was in the steering column. That was replaced and the problem fixed, but it cost more than $2000, and that's using second hand parts. That said the engines and gearboxes, etc., are bulletproof. We don't have the same feedback on the C-Class, but remember all cars have problems; no car is completely free of trouble.

Should I buy a second hand 2012 BMW 328i imported from Germany?
Answered by David Morley · 03 Mar 2021

That’s quite low mileage for a 2012 vehicle and, on the surface, suggests that it has led a pretty easy life. but you’d still only buy it if it is presented with a fully-stamped service book to prove that all the critical preventative maintenance has been carried out. These are complex, high performance cars and they won’t tolerate neglect in terms of skipped services.

The major mechanical problems with these cars were found in the engine’s variable valve timing (VANOS) system. Any 'Engine Malfunction' message or 'Check Engine' light in the dashboard could quite easily be caused by a fault in this system. The VANOS arrangement was also the first system to show the effects of poor servicing, so make sure it checks out before you hand over the cash. Fundamentally, though, these cars are not low-maintenance units, so make sure you budget for the necessary ongoing servicing.

Don’t forget, also, that this series of BMW was caught up in the Takata air-bag debacle. So make sure the car has been attended to as part of the global recall and don’t take a chance on any car with no proof of this air-bag replacement being carried out.
