My wife has a 2005 Volkswagen Golf 2.0FSI GT with 51,000 on the clock. The light in the ESP switch, and the dashboard steering wheel and ABS signs, have all come on together, intermittently, over the last six months. They usually come on after heavy rain and then go off again if the engine is restarted after a few miles. As a former amateur rally driver, I have driven the car off road almost on the limit (but of course safely) with the warning lights both on and off, and can detect no difference whatsoever in the handling and braking.

I know that you have advised many times, in response to readers letters, about a known problem with the ATE Teves unit. However, on speaking to a relative who is a manager at a VAG garage (in a different area of the country) he confirms the known Teves problem, but that there is an even more common problem with the sensor being faulty. I do wonder, therefore, how many VAG car owners are paying astronomical costs for a replacement Teves unit, when it is only in reality the sensor that is at fault.
