Turbo Lag below 2500rpm

[Michael112]

Hello everyone. I am new to this club.

I have my is220d for over 6 years so far and never had any problems since until now.

Everything has started with the white smoke from the exhaust (it seemed to be dpf regeneration), but after few longer runs with highier rpms that seem to be gone.

Few days ago i have noticed that my car has completely lost a power until the turbo kicks in at arround 2500rpm. First thing i suspected and as found on various forums was egr.

so got that cleaned but still no luck and no power.

I have done cars health scan (on my friends diagnostic tool) and it became with quite few faults which i cant really understand. (pictures attached below).

Would someone be able to identify the problem or maybe someone had similar issue with is220d in a past and how this been solved.

 

Thanks in advance

With that many errors I'd question if there is an electric issue causing multiple sensor problems. I'd check the Battery is ok, and the earth connection and straps.

Worth disconnecting the Battery just to reset everything.

You've taken a note of those codes (screen shot) so clear them, as they may be from old issues.

Then run the vehicle and see what shows up as current codes/issues, hopefully that's a shorter and more accurate list.
