I just visited Autobahn East (just google it) autobahneast.ca/
and Mark simply did amazing job!! He fixed my A/C where no one else could found a problem.
Trust me I brought my car to many shops include several BMW dealerships and they couldn't even locate the problem.
Mark spent almost an hour to inspect every single detail and finally found a problem.
I ordered a part from bimmerspecialist and got fitxed it today.
It's been 2 years of summer driving without proper A/C. (cold air front the middle vent, and rest of them blows mixed cold and hot, My temp control didn't work at all)
It turns out that "heater valve" was the problem.
If you live near ajax, you guys are so lucky to have him nearby!
Once again Thank you Mark!!!
