The Problem
It is very common for the stainless-steel exhaust manifold to crack causing exhaust gases to leak.
The stainless-steel exhaust manifolds fitted to many BMW vehicles frequently fail, often after as little as 40,000 miles, with some vehicles having 2 or 3 replaced so far. These manifolds are not suited to the conditions of the fitment and through expansion and contraction with heating /cooling eventually fail. Developing cracks or slits in the manifold causing exhaust gas leaks and the symptoms noted. These stainless-steel manifolds are simply not up to the job, BMW still offer these as replacements at a vast expense, fitting another stainless-steel manifold it would just fail again.
Symptoms of the fault
Smoke coming from under the bonnet, soot evident under the bonnet, smell of fumes – particularly when sat at idle. MOT failure for fume leak. Hissing sound or sound of gas escaping. Exhaust gas smell within vehicle cabin.
Leaking of the manifold can cause further faults such as louder engine, slower turbo response, less torque, decreased fuel economy.
To be sure of the fault it is worthwhile inspecting the exhaust manifold, using a mirror / torch it should be possible to inspect the manifold at which point cracks can usually be seen or soot / fumes can be seen.
