Hello I am looking for sound advice re my A4. I am getting multiple brake error warnings when I switch on my HID headlamps. If I'm driving the speedometer drops to 0 and stays there until I stop and switch off the car. On restart all the warnings disappear except the traction control. My mechanic says it's related to the ABS control Module as it's giving his reader an error. I'm not convinced because the brake warnings come up every time I switch on the headlamps and if the car has been sitting overnight or for the day.

I'm also looking for a reliable & honest mechanic in North Vancouver or nearby.

Please let me know if you have solutions or any advice.
