Compression check
Hey was wondering how to do a compression check on these cars. TIS's states to hook up bmws compression tool that checks all cylinders. I've always done it manually on my previous cars with a compression gauge. Just not sure the process on this car as you have to remove the charge pipes to get to the plugs and which fuse i should pull for the injectors.
