EGR valve

[king2136]

For a w210 e320 cdi. When you block off your EGR valve which vaccum pipe do you block off OUT or VAC ? just checking that the garage blocked off the right pipe.

Did you do the above ? Thought it messed with the ECU ?

You can't just block a vacuum pipe. The MAF still thinks its there. Have a look at this thread from then other side:

Cheers, a bit beyond my mech ability so will stick with trying to clean the EGR of 140k of gunk.
