Hello chaps,

I have a 2006 2.5 Tdi (auto), Have been getting exhaust fumes in the car for a while, so decided to replace the cracked exhaust manifold.

Not to bad of a job, apart from 1 manifold nut. All back together and now it runs lumpy at idle and knocks went revved up to about 2500 rpm.

Any ideas of what I've done?

Thanks in advance.
