Hello and i would really appreciate some help with this problem! when i got my s3 the abs light and the esp were both lit up. fault code points to longditudinal sensor. ok, so here it is, i have changed the londitudinal sensor and the lateral sensor and the abs module, have had the wiring checked, the basic settings reset and reset and all manor of diagnostics, i have got not a clue what to do next other than get rid of the car. The only thing i will say is, if anyone has any ideas or wants to take a look at the car for me it would be most appreciated. or if anyone can point me in the direction of a good abs specialist in the london area. thanks very much car is a 2001 s3 facelift.
