Hi everyone,
I have a 2000 apy s3 with the mtm kit on it, and i have been having some issues with traction control light comming on.
Running the car
So when i start the car up the light does not come on, but when the car is driven off say 10meters down the road the light comes on, and stays on for as long as you drive it. But say i drive it 10 miles once the car is nice and warm, then stop the car turn the ignition off then turn it back on again and drive away there is then the traction control light does not come on. and the car runs as normal.
When the car is sat ignition on but not running before running
When the car has it ignition on and not running, all i can here is the Haldex pre charge pump running, all the time. It only seems to stop when the car is warm after a run. please see video below. This pump appears to run non stop wile the car is on ignition
So what have i tried?
1st I read as much as i could off this fourm.
2nd I checked the fuse and all is well.
3rd I checked the plug at the back of the diff - and it is like new inside.
4th I chased back all the wiring to the pre charge pump from the plug its like new inside,
5th I chased back the wiring through the boot of the car and all the way down the passenger side of the car - all is ok.
6th I checked for the earth strap off the passenger side of the rear diff and i do not have 1?? - it seems not all were fitted with it?
7th I herad it may need a service - so it was all serviced today and they said it still hd the original filter on it!!
8th I took it to a priviate field to test the 4x4 works - and yes it does
9th had it plugged in, 1 fault came back heldex related, 01312 - power data bus - esp 37 - 00 faulty, and part number 02d900554b which after a search seems to be my controller. another fault was 01324 f code 49 -00 part number 8no907397 and this seems to be a abs pump. Linked? By the way i hope i wrote these ok, i litterly scribbled them on the back of a box.
So questions for you people, and what do you think i should do next?
With the 9th item do you think 1 of these faults could cause the other? do you go for a new controller? or abs pump? or both?
Do you think the potential lack of service has damaged something?
Do you think i should fit a earth strap?
Is there any other plugs or wires that anyone knows of that i can check.
Any help with this would be great, im going to look for a cheap controller to try i think then go from there? Thought any one?
Thanks Phill
