Anyone know the part number for the small turbo charge pipe bolts/clamp plates


I appear to have lost one of the 5mm turbo charge pipe allen bolts/small clamp plates


which may explain the whistling noise at about 1750~2000rpm


but now the car is making a thud thud thud noise on idle and driving


bit like a quiet helicopter sound coming from the engine


ive been doing a bit of investigating and stripping down, somewhere in the region of 3-4 hrs worth to be exact, on top and underneath



ive taken the red boost hose off suspecting that may be split or leaking, the car is 01/2008 and the red BMW hose is date markered up 04/2010


so its obviously been back to the dealer to have the revised or just new hose fitted since the car rolled off the production line


could be the seals on that pipe, im going to get a forge silicone one with new seals at the same time



one problem seems to lead straight into another


am fearing the small turbo is shot, the large turbo feels fine to the finger tips

OP, go look in realoem.com. I must admit I don’t exactly understand which part you are asking about. How about a picture please?

I always wondered why they don't come with 2. I ordered an extra and put em on just to fill in the blanks.
