Hi There,
I have this problem, two weeks ago it is all started with a faulty left turn signal. I replaced it and it worked fine.however, the mechanic was not familiar with German cars so he had to dismantle so many parts at the left side to get to the bulb. Once he put every thing back and turn on the vehicle the EPC alarm and check engine light came on. later on I found out that the brake stop lights and the cruise control are not working. So my question is:
What part of the brake stop light harness connection that might be affected during our bulb replacement? before that every thing was fine.

Appreciate your inputs

Hey REMO2004,

It sounds like he either left a wiring unplugged or forgot to reconnect a ground wire. It will need to be taken back apart to see what he did wrong.

Please let us know what you find so it will help others.

Hi Ken,
Thanks for your reply. I solved it and it was very simple. When we changed the bulb the first time he used a bad quality bulb which make the fuse blown every time. When we changed the bulb for the second time we took the Brake light Fuse to test the bulb and we forgot to replace it. Once I figured this out and put a new fuse all things worked fine.
