E92 m57 335d loss of power! EGR 4030 error?

MCCoding · 10-14-2021, 09:53 AM

Hi all, been a big follower for many years but this is my first post!

I normaly find a lot of good info, but have not found much about my issue ( if someone has spoke about this before, i apologise)

Long story short, the BIG turbo does not kick in!

I have a stock m57 with dpf and egr delete. However, i have recently got a EGT error 4030. This may be the reason why my big turbo is not working? (NO power after 3k revs, and its like a sloth with the revs thereon after unless, i shift the gears; and the small turbo kicks in)

This happend right after i upgraded my intercooler (aftermarket). I then panicked and upgraded my boost pipe AND vacuum lines but still nothing!

Im going crazy! Please help

Again i have no performance map

Just the usual. DPF, EGR, Swirl flap, EGR cooler delete

Look forward to your responses

Many thanks
E92Mani
