I own a 2007 A3 Sportsback 2.0 Tdi which has recently started displayng the car skidding symbol in the dash. Additionally, and 'ESP warning' appears on startup. I have scanned the fault using vdcs and it shows error G201 whcih IM led to believe is a common fault with the abs control module. I have seen exchange control modules for sale and now want to know how to remove the old module and fit the exchanged one. Somewhere I heard that access can be gained from inside the near side wheel arch. The n/s side wheel and inner mudguard must be removed. Anyone know if this is correct or know of a DIY guide on replacing the control module. Add info welcome.
