YTMercedes  Mercedes w212 e250 DPF issue
Hi all, this 2009 mercedes has recently had the DPF professionally ultrasound cleaned but it's doing regeneration every 50 Kms, he wants me to delete EGR for him but there's no fault codes present so I don't believe this will do him any good, he's already installed new injectors, maf and DPF pressure sensor, still regeneration every 50kms, any ideas why this is happening ?

He says that the car was never remapped but the issue started after the car was recalled to Mercedes for a subframe installation and they updated the car

hey mate, is the turbo ok? no oil leaks in the intake? because one time I had similar issue and the turbo leaks compromised dpf.
