Still having problem with the OMP.
I have an S5 na. I've scanned the ecu and have code 27 OMP issue. So i've changed new oil lines and bought a used OMP and still having the same problem. Any idea what might be? The check engine turns on when i rev sometimes in 3,800 at 6,000 too, and sometimes even at 2,500. Hope someone can help me out.

I also have a similar problem as you. In reading some posts about this issue I found that many times if the OMP fails it takes the ECu with it. Did you replace the ECU with a known working one with no codes? If not try that and see if it fixes it.

seems like a lot of folks (myself included) are having / have had this problem. A somewhat common solution is to "trick" the ecu and just use pre-mix. search around the forum, lots of information on this issue and possible solutions.

Well, I've opened the ecu and it is burn out, 2 resistors and a kind of chip(don't really know). I have another question, my S5 na vert has the 353 ecu. Is there any problem if i put a 351(89-91) ecu?
