I've got a a4 b7 2.0ltr TDI and I'm not sure If it's just my imagination or if the engine is vibrating and noisier than usual while stationary
So I've read alot about cleaning the egr valve on the car so I'm going to have a look
The cars only done 41 thousand miles but the previous owner ran it on supermarket fuel so think it might be caked up
First things is do I need 2 new gaskets ?
Then is it carb cleaner I clean it with
And finally can I just check is this the valve in the picture and I'm guessing you undo the 3 Allen key bolts the 2 at the top and the 1 underneath ? Then undo the connectors and pull it out to clean
Do you then just replace the gaskets and bolt it back on ? Do you need to rest anything using vcds ??
Just got a few nerves as I don't want to try and fix something that's not broken and actually break it lol
