Thread: Fume into cabin of D4 3 Ltr TDV6 & Potential EGR issue

Does it relate to EGR vale but I did not check for fuel consumption for a long time since the lockdown from last year in Melbourne? No engine noise as other EGR faults. Can I use Gap iidtool to detect EGR vale pressure? No fault code come up yet. Attached picture was another suggestion of the leak. Thanks.

Ours does/did this, it was a cracked turbo crossover pipe on the left hand side back from turbo, I'd check there for black soot etc..

Good thinking. I’d forgotten about that fault with these
