Hi all,
I recently bought a audi a4 avant 53 plate and have noticed an issue when braking lightly. oddly enough this doesnt occur under heavy braking but when braking lightly the ESP light comes up on the dash and when i push the button to turn it back on nothing happens the only way to get it to work again is to switch off and on the engine. I have connected it to a friends computer diagnostic machine but there is nothing logged in the codes about a fault. any ideas other than replacing the sensor.
regards,
