Okay here I am again.
In my 2000 S4 Avant.
Having got wheel bearing sorted and run VAG COM I can not see why my ESP light comes on under hard acceleration.
Usually in third around 5000rpm but it can happen in 2nd lower down.
I have used VAG COM to record wheel speeds and other ABS/ESP sensors all are fine and no fault codes anywhere else.
A quick run recording engine values also looked okay.
Boost pressure maximun at 1750 ish from a 1010 tickover.
MAF peaked at 204 under load 5-6 at tickover.
Labdas both peaking at 8-10%
Any advice on what I could log and what the values should be to check MAF, etc. Have had a quick go but not sure how to verify that the answers/graphs are good.
Car still pulls well. Is it a good idea to try a FATS test with the ESP off?
At least I can be confident in the engine then.
It looks like I need a trip to a specialist.
Can any one recommend the easiest to get to from Weymouth?
Thanks in advance.
