Now my 135 is jacked....the idle fluctuates, turbo is lagging and it switches over to limp mode as it pleases. Its been at the dealer for the past 3 weeks. I love the power of that engine and they have a sweet growl but what a huge pile of garbage.

Ive had such poor luck that I just decided to go back to the non turbo I-6 and havent looked back. Im waiting to find an e46 m3 and im gonna roll the 135 off a cliff. The I-6 is easier to work on and less prone to issues. I have towed a 24 foot maxum with the X5 and not had much issue....it get the job done well.
