Posting on behalf of a friend, he has a 2005 Audi A4 2.0tdi BLB engine. He had the dreaded EGR and shudder valve fault which both parts have been replaced he now gets code p0244 turbo overboost

We have checked the car over and have found a small leak between the manifold and EGR, this is due to not have replacement seals at the time of fitting.

We now have the correct seals so they will be replaced accordingly.

Could this leak have caused the overboost? And if so why

Hope you guys can help
