Here is a quick photo guide of how to clean your EGR Valve, my car is a Vauxhall Vectra C with the 1.9cdti 150 engine on a 2006 plate. Its got around 46k on the clock and a few months back the EML came on a quick trip to a local Auto Electric place confirmed it was the EGR Valve stuck error.
Apparently these can stick quickly and then free them selves but still throw the error up or then can cease permanently. Anyway the light came on again so i decided that it was probably worth taking off the EGR Valve and giving it a good clean and the mouth of the inlet manifold.
I’m not a mechanic by trade but i felt confident that this was easy enough to fix and probably took me around 40 minutes.
Things you will need
10mm Spanner or Socket
13mm Spanner or Socket
Flat head screw driver
Carb/Injector cleaner (i used 2 cans)
3: Your now looking at a bare engine, your EGR Valve is directly under the top right engine mount.
6: There is a sensor cable which attaches to the plastic side of the EGR Valve, i found this fiddly to remove whilst bolted to the engine, so i left it attached until the EGR Valve was free and removed then, now remove the bolts i would suggest leaving a top one till last, there is also a metal gasket between the EGR and inlet mani, mine was stuck to the engine, but be careful and try not to lose it.
8: There are the 2 top bolts here which connect to a loose bracket, underneath of the EGR. To be honest you can remove these first if you want, infact its probably easier, i think that there is a gasket under this between the EGR and the connection, anyway I’ve lost mine and all seems fine.
10: As you can see mines pretty caked with soot, soak with Carb Cleaner and wrap a rag around the screwdriver to clean the inside, if i had the time, i would of left the EGR Valve to soak in Carb Cleaner over night.
Now all you need to do is fit the EGR back on to your car. a word of warning before you start your car.
Mine didn’t want to start the first time and it did idle roughly for a minute or so, which I’m putting down to loose soot and Carb Cleaner.
