Right, egr removed and cleaned (wasn't too dirty), and all moving parts moved, nothing stuck. Broken wire on plug to n18 egr valve fixed. Ran vagcom again, code 001027 now present and won't be cleared. Engine power restricted but seems smooth with steady idle, no excessive smoke etc...

Even changed the black plastic egr cover with mni geeks but alas, same problem... I tried the vagcom output test of the egr which does on-off-on-off etc but it doesn't make a sound like its opening/closing so I'm guessing the actual valve is faulty even the plunger to opens the valve can be moved by hand which only points to the motor that controls the plunger...

Reluctant to shell out on a new egr without some reassurance that's to blame... Any one else had this code?

So, as all connections, hoses, etc had been checked numerous times and the vagcom was pointing to the egr, which didn't seem to be opening and closing with the output test, I bit the bullet and replaced the egr valve for a new one.
Reassembled all parts, checked connections, turned key to position 1, glow plug light on, then off as per normal so I start the van.
After 30 seconds, glow plug light starts flashing again.

Sense of humour failure, much swearing and I've decided to come inside before I make expensive mistakes with a wide variety of tools...


No longer feeling the love for the van, the egr, the f$*kwit that designed it and put the bolts in hard to reach locations etc and deciding that getting a van to inhale its own sh01te was a good idea....

I hereby admit defeat and will accept the first reasonable offer... Yep I'm that annoyed with it.
