My friend has a 2001 TDi (115BHP AUY engine) that is rattles at tick over but fine when driving, it returns good MPG and it doesn't use any fluids.
I put it on VAG.COM and discovered the start of inj. is 6.1 BTDC at idle and it should be within 1 BTDC to 2 ATDC, as you rev the engine up it backs of to about 9 BTDC. I have the same engine is a 2002 Galaxy that is running fine, that idles at 0.8 ATDC and backs of to about 9 BTDC when reved up.
Sounds to me like the injector timing on the belt is out but I am no expert, what do you guys think.........
Oh and if I could be cheeky and ask 1 other thing. His specified and actual MAF readings are both about 250 at idle but my actual is way up at about 490, I haven't noticed a problems with performance but is my MAF about to give up on me?
Thanks you very much for reading and hopefully replying.
