I know this is a long shot but wanted to reach out to see if anyone has an idea.
So far two BMW techs have been unable to diagnose my significant loss of power issue. I am at about 25% power and the car literally shut off on the highway at 75 mph.
I had used cats installed which for awhile seemed to help but I am right back to square one.
When you accelerate the car simply doesn't respond and you hear a womp, womp sound like the car is bogging down (only way to explain).
So far we have checked the MAF, the DISA, the vanos seals, the reluctor wheel, cam shaft sensor, crank shaft sensor, PCV, timing chain, etc.
It is throwing no appreciable codes of any sort.
Tomorrow he intends to do a compression/leak test.
What are we missing??
