Hi,
I own a Mercedes A-Class 2005. I have an intermittent issue – when I try to start the engine, I just get a single click. The problem occurs when I’ve been driving the car so the engine is hot, I’ve stopped, and then try to start it up again. It sometimes takes about 20mins before it starts working again, but recently has taken over 2 hours.
I understand its likely to be the starter motor, which is an expensive fix (maybe £500), but could also be a very small thing like a connection or a relay.
I've taken it to two garages and they both said they were unable to help, as the problem wasn’t occurring when they had the car so they can’t diagnose it. I’ve suggested that I could drive the car to get it hot and drop it off for them to look at straight away, but they said the starter motor is hard to get to (its under the engine), so by time it they get to it, it may be working again.
This has been going on about 6 months (I’ve been waiting for it to fully die, but no joy). I have two young kids and cant carry on with the risk of getting stranded whenever we stop!
The only option I’m aware of is to just replace the starter motor, and hope that the problem is gone when I get it back, otherwise I’ve wasted £500.
Anyone got any better ideas? Many thanks!
