My car has been suffering an intermittent electrical / starting fault over the last few years and it seems the mechanics at the local Porsche independent are unable to identify the problem.
I think it's time I tried a different tack, so I'm looking for recommendations for the best auto-electrician, based in South London (as that's where the car is right now), please.
The problem manifests itself when the engine is hot (i.e. above normal cruising hot). After the engine has been switched off for a few minutes (say, to refuel), the engine won't restart. The usual ignition / warning lights come on, but nothing happens when the key is turned to the start position. After allowing the engine to cool down for 15-30mins, it will start normally. Once started, the engine runs fine. Provided the engine doesn't get abnormally 'hot', the car will always fire first time, even if restarting.
The usual diagnosis is a faulty starter motor - that's what I was told this morning, until I pointed out the garage had fitted a brand new one last year (a few hundred miles ago), when I'd been told that they had found and fixed the problem!
An immobiliser issue (it's an aftermarket unit that otherwise works fine) could be another cause, or a dodgy contact / wire somewhere which opens up when the engine is hot.
Seems to be one of those hard to identify (i.e. no fault codes generated), intermittent faults that mechanics hate these days, and it might just be more profitable to turn the focus on the potential electrical issues than keep fitting new parts.
Thanks
