Hi Pellesin, thanks for the reply well I changed the camshaft sensor but had no joy which leads me to suspect the Crankshaft Sensor is faulty.
Does anyone know whether Lucas SEB 1400 Crank sensor is the correct fitment for a Audi A8 2006 3.7 V8 Petrol?
I'm getting mixed matches from eBay some seller say it's a direct replacement others say it isn't.
Very confusing - if anyone can confirm that would be great
