Boost problem c220 cdi 2012

Hey......my car has gone into limp mode and computer indicates that there is a air leak somewhere.......i have replaced the intercooler pipe and the trottle body seals also the vacum transducer......but the same noise persists and is coming from left side of car......if sat in the car you can hear it coming from passenger side air vents...........can the intake manifold leak air......any clues guys????
.......its driving me crazy

You need to do a charge pressure test to confirm the air leak and then a smoke test to locate it, but its likely got a snapped inlet manifold bolt.

If it is a snapped bolt.....would i have to replace the full inlet manifold......if so do you know how much it can cost???

Yes, the bolts are captive in the manifold and have since been modified.

Its roughly a £1000 job at an indie.

Do the bolts break in the engine block and need to be drilled out.......or are they pretty easy to remove and are snapped in the manifold itself......seem like an expensive dooo.....

The snapped bolts may have to be drilled out. Depends where they snap. It’s not hard to get them out.

Would the engine need to come out???

We don't take the engine out for this. Its a horrible awkward job though.
