ESP/ABS Error Code

[Boydave]

Hi all

I have an ESP/ABS fault (both lights come on and stay on until ignition is turned off), I recently plugged the car into my m8s VAGCOM
It came back with error code 04FF – a longitudinal acceleration sensor.
I've tried doing a search but nothing matched.
I was just wondering if anybody knows anything about this sensor, or have come across this problem in the past, wouldn’t mind knowing what kind of damage I’m looking at
Any help would be greatly appreciated, I don’t even know where it is /ubbthreads/images/graemlins/noidea.gif

Cheers BD

Hi m8

Had the same lights on recently but fortunatly it was a brake sensor and cost about £6. When i was investigating the problem i came accross the longitudinal sensor and i think they are quite expensive. For some reason £700 rings a bell hope im wrong. Not sure where they are located.

I too remember a post about it, iirc there are two one expensive and the other astonomical! IIIrc too, one is located behind the centre console, not sure as I only have ABS not ESP

i think you will find it under the back seat in the middle

I feel sick all of a sudden /ubbthreads/images/graemlins/vomit.gif, lol

Thanks guys, first I just need to find where the sensor is hidden so I can test them with a multimeter, don't fancy going to a dealers, so they can have my pants down, just yet.

I’m told there are 2 of these sensors.

Yaw sensor thread - attachment from khufu for ESP

By the looks of the info from the tt forum guys, the combined yaw and acceleration sensor located in the steering column is the horrendously expensive one. The longditudinal one is behind the glovebox area (i think) and looks like its about £80ish.
