Right guys after taking my car to the garage ive narrowed down the engine bay noise.
cars a 2001 mk4 1.6 16v.
mechanics called it engine pinking,does it at low revs when the engines under strain, ie. pulling away at junctions and driving up inclines. it matches the revs of the engine,and disappears once youve pulled away properly.
seems to happen in lower gears rather than higher,and we also managed to get it to do it at idle by straining the engine.
The mechanic is unsure, hes gonna plug it into a lappy when it goes for the MOT,but its weird, no EML is coming up or anything,and the car runs fine otherwise.
He suspects it may be an ECU problem,that the ecu isnt giving the engine the right timings or something.
so ,any other ideas/theories?
im not sure if its a serious problem,but the noise is bugging the crap out of me!!
