im thinking of trying the resistor trick en egr valve by shorting solenoid connection ,anyone got idea of value and size of resistor needed,
                                  many thanks

doubt it will work as i suspect their is a feedback circuit (don't know for def on 2.2dti though).

Cleaning the valve is the usual fix for poorly serviced vauxhalls with dirty egrs

How many pins does the wiring connector have?

If just two you may be able to do it OK.

I measured the resistance of ours a few weeks ago.  Can't remember the number but it's on here somewhere.  I'll try to search it out.  If I'm correct in remembering it was around 30 Ohms [Edit; yes it was], then you'd want approx. 10W resistor.

Part number of EGR valve would help confirm whether it's the same.

thanks abiton,part no is 93170138 and it has 2 pins,ive cleaned it dozens of times and filled it with wd 40,checked all vacum pipes,..i just want to disable parmanently
                                thanks

That's a different part number from the X20XEV version, according to the Trade Club book, but I'd be tempted to take a punt on a:

10W W/W 33R H33R £0.46  In Stock

from Maplin.

Don't think there's any risk, but if there is I'm sure someone'll point it out soon.

fitted resistor,eml still on and off tried blocking off vacum pipes still on ,how do i clear codes with out code reader,tried dissconnect battery but powersounder goes off
                                    thanks

Of course its different - diesels use a different egr.  Diesels also use massive amounts of egr for economy.

Certainly the 2.5td engine measures the amount of egr used indirectly by calculating fuel/air

I'm so glad I went back to old school with the 4x4
