Any ideas on what this sound could be? Audi A3 8P
Hi all does anyone have any idea on the problem my car has, I have a tapping noise at idle and speeds up with acceleration and can hear it inside the car doesn't affect performance.
First heard this after I had my glow plugs changed, had these checked and all seem to be correct size and fitment and no debris in cylinders.
Its had the rocker arms, lifters, injectors and all cam followers replaced and noise still persists, havent replaced camshaft but was inspected and all seemed to be okay.
Been advised by three separate mechanics its not bottom end so at my wits end really, any thoughts appreciated.
Car is a 2.0tdi 170.
Thanks.

Hello
Thanks for your reply johnny, the garage plugged it in and it came up with injectors i believe 3 were down so had these replaced first and the issue was not solved
I took it to several garages who all said the same thing, after the injectors were done, again i took it to several garages and was told lifter tick.

You need a real mechanic, not those guessing-guys in them garages who only want your money without having a clue.
