Salut. Try and report. Not checksumed. See if mpps can do it on the fly, or wait a proffessional solution here. Succes!

Salut! I have already tried with dtc off and egr off, the light does not come on anymore but the limp does too!

It looks like bad fuel mixture in load. I ghink this cannot be solved by remap, but by mechanical repair. Maybe i'm talking bullsh...
Just my oppinion: air leaks into tank or on diesel hoses? Did you try with full tank? I think is underpressured. Or loosing fuel pressure

I have replaced turbo, because i was getting a lot of errors and low turbo pressure! Before i was getting P0638, P0100,P0400 and P0234! now only errors P0638, and P0100! Now uphill goes fine, no limp, when down hill after a while it goes in limp!
I have no errors of bad fuel timing or debit!
