Thanks for this. Just got the codes about a week ago. Found the tube cracked as well. Hope it fixes it.

Fixed it for a short while, then it poped back on. Tonite driving home, started running rough. Pulled codes, and I now have 0313, 0300, 171,174, 306, 303. WTF. I guess Sat I will have to check the Disa, and look for vac leaks. Luckily it is not the main car, but Sat morn is when I am going to sign the deal for my Euro Delivery of a 435i M Sport. Don't need to spend more money right now!!!
