Engine Electronics Warning light - MkIV Astra

Sounds very much like an EGR valve problem (Exhaust Gas Recirculation). Vauxhall have had problems with EGR valves and have modified the design , they have also changed the EGR valve gasket material. If this is the case , the problem will get worse and the light will eventually not extinguish. You will need to have any fault codes read from the engine ECU on your car and see what fault is stored. On some cars (particularly the 1.6 litre single point versions) there is an ECU fault which can produce the same problem. Best of luck Mike

First off, change to decent quality petrol and see if that stops it. I have frequently come across the light being put on due to inferior fuel, so if you are a supermarket fuel buyer, try a tank full of ultimate or the equivalent, it may well cure it.

Funnily enough, I just finished a tank of "ultimate", cos it was all they had the day I filled up my car. Don't normally buy it though, but I do try to steer clear of supermarket forecourts all the same. I'll get the ECU checked, and take it from there...

Thanks again, DSt.
