2008 335i engine malfunction
Hello guys. I'm new to the forum. Hope everyone is doing great.
I have a 2008 335i for a while. It has 73K miles in it but is in great shape. Hoever once in a while and not under any given condition the engine lights comes on. I've taken it to various BMW mechanics and they can't find the source. They plug in the scanner to check for codes and the only message that comes in the scanner is " Boost Deactrivation "failure". No assign codes reflcted. Engine looses power but does not stall. It keeps running. Then you stop, turn the car of for a couple of seconds and continues to run normal for days and perhaps weeks. It comes on during any type of driving. Accelerating, running steady at 55 mlies. There is not a specific pattern.
No one seems to find what it is. Anyone having a similar issue??
