BMW 123d drop in power at 3000 rpm

Post by UniCroN » Fri Mar 23, 2018 12:06 am

I been having a problem with the power dropping from 3000-3200 rpm. Car otherwisefine runs fine and there is no other problems but it is getting a but frustrating.

I have changed the glow plugs, glow plugs relay and changed the dpf and it still has the same loss of power and ideas?

Engine has only done 40000km

A dyno with no tuning and after tuning where its shows the drop

I'm sure we had a 123d auto a few years that had been tuned by another company already that did this and when we put it back to standard it was fine
We then tuned it our way and it never did it

I still havent fixed the problem.
It has been tuned by a Danish Company who used to have a 123d and tuned it without problems. I Think its a mechanical problem.
