Has anyone found a work around on the m274 engine crankcase breather? I have found that when turbo pressure enters the crankcase you get a code, the pcv valve is supposed to stop this , when it fails the computer senses the extra pressure, i installed a 10mm check valve from ebay for 2.99 and the light whet out.
Did you see the post one page back on this thread about replacing bleed line?
Also can you post detail of your fix? What part and where on the car?

Another huge thanks to Metros for coming up with a solution to the PCV purge valve issue. I completed the repair this past weekend using his technique. As has been mentioned previously, there was oil leakage into the connector portion of the purge valve. The van has 56k miles on it and the check engine light has been 'silent' for 50 miles so far...
