Right, got my new EGR valve today, and fitted this afternoon - is a bit of a bitch to do, cant really access the bottom clip for the pipe...and obviously I kept dropping tools and bolts down into the engine...
After driving home from work, my average mpg was 51, but I got caught behind a slow car and this isnt reflective of my usual journey home. As I sat at the traffic lights I saw my average mpg go down to 46, but I had only done a few miles...
I cant see if its still smoking, as I didnt have anyone following me, and couldnt boot it enough to see.
I got a few errors over the last few days, but no real loss of power, just a flash of engine warning, but I think thats my un-relocated boost valve playing up in the rain...
Will let you know if my mpg picks up. Should it take some burning off of old crap before I take the readings seriously?
