The car has covered 38000 miles and the esp light does not go out when engine is started. Have been told by main agent that it could be electrical fault or 4x4 controller. They wanted the car for 5 hours to investigate fault but i declined there offer as controller costs

By 4X4 controller do you mean the Haldex ECU which is mounted above the Haldex unit at the rear? A number of 4X4 owners here have had problems with that ECU displaying an error when scanned - normally a checksum error - but it doesn't cause the ESP light to come on. That ECU costs circa

Have you had the car checked for fault codes I had an air mass meter problem which showed up with the ESP light coming on although this did reset when you switched off the ignition.

If it is the controller then search the scrap yards, its not I believe a common problem so you should be able to find a good one & odds are the scrappy wont know what its worth, tell him its

my ESP and ABS lights keep coming on but mine is the longitudinal acceleration sensor which is getting ordered in a couple weeks

Does sound like a fault with the Haldex ECU if it is clicking.

Where abouts are you?

Jebus! Nightmare stories there mate

Ref: Haldex ECU, Awesome Gti. show what appears to be an up-rated part under Audi A3/TT section,

tis an uprated one indeed, bit pricey though

Agree with Lummox, ESP light and clicking haldex is defo the haldex ECU. I had this when I fitted a used one that was sold as 'perfect working order'.
