We have recently had a new clutch and flywheel replaced on

Resolved Question:

We have recently had a new clutch and flywheel replaced on our mini 07 reg. Since replacement fumes have been coming into the cabin. We've driven the car less than 30 miles since the replacement. The car is now back with the garage who did the replacement. They tell me it MIGHT need a new CAT and or DPF and say that its not their fault. We've never had a problem with fumes before and didn't have until the car went into the garage.

Hi..there thanks for getting back..

Normally with any type of exhaust fumes leaking into the cabin is down to leak somewhere at the front of the exhaust system/manifold or gasket leak.egr gasket leak which i can see it being to be honest...The cat converter "if petrol" shouldnt cause this unless it was damaged/corroded allowing gases to escape...if a diesel engine 1.6d then the dpf normally doesnt cause this either,you may find a hot type smell under regeneration..they should recheck the joins/differentail pressure tubes/aswell as turbo unit connections,egr....the fact you had the clutch done and this problem arisen would suggest they have removed parts of either of the systems above and not sealed them back properly..thats my understanding without seeing it and the only real cause for exahsut fumes to enter the cabin... unless its fuel smell then that would have to be investigated for and should be easily spotted for wetness - they have to properly recheck the system is sealed properly at the joint/gaskets...rather then guess whats wrong at you expense..maybe get a second opinion and take you findings back to them..I do hope this helps
