Possible boost leak

Mybimmer · 01-11-2018, 04:58 AM

I noticed over the last week or so my spool up is happening later in the rev range than normal. Have not done a pressure test nor smoke test on the system yet.

Went for a run and pulled a few logs. As you'll see load and boost targets are off and you can clearly see spool up later than it should.

New OEM turbos only 2000'ks old. So I doubt any problems with them.
New boost pressure solenoids installed today. Made no difference.
New Vacuum lines all round. Made no difference.

Check the charge pipe for leaks. Also check intercooler piping.

Reset adaptations and take a new log?

Thanks mate. Yes all adaptions reset via INPA before the posted logging.
I'll smoke / pressure test tomorrow.

Yep was the charge pipe. Should have known better to buy a Chinese piece.
Swap the stock pipe on and much better.
