NTR - EGR Valve

simonh · NTR - EGR Valve

on my zafira, the EGR Valve is giving a fault code so the management light is coming on.

Anyone know if it will affect the CAT if I blank of the EGR, and will there be anyother side effects. I'm assuming that more damage would result if I left the faulty unit in operation.

Reason I ask is, its a common fault on vauxhalls, and fitting a new one would only cure it temporarily (3000 - 10000 miles)

depends on the age of the car but most wont run without the egr valve just had this problem on a vauxhall 2.2 diesel frontera/vectra engine also it can show faulty egr valve if the little air pipes are bust on the car very hard to find without a vacum tester took me all last week to find this after buying a egr valve

I had an astravan years ago and the airbag light used to come on regularly.I put some black insulating tape on the dash covering the light.That seemed to do the trick

It might be the bulb that's faulty if it keeps coming on.

Apparently you can blank it then program it out of the ecu, so the ecu deosnt sense it anymore.

just its driving like a dog now, so want to blank it and sort the ecu programming later

the blacking plate is available form Main dealer, they will also remap the ecu for you, no harm to cat as far as I can see...

"Took it to PICADOR Vauxhall who told me that Vauxhall advice was to change software and blank off the valve which they did for just £45 !!! (excluding the diagnostic which I had already had done). Car runs great now. Interesting difference in the 2 dealerships ?"

plug in at a main dealers is about £80 I think

but it will be sorted
