2.0tdi egr valve fault and less MPG!
Hi! cleaned out my egr valve last recently and found it was coated with soot, so was the intake manifold so gave them a good clean. Also the flap was stuck open and wound't move freely before. After cleaning and installing back, I got a warning light saying, "insuffient egr flow"! :S it was blocked and covered with soot before and no warning light and after I cleaned it i got this with VCDS! I then couldnt be bothered paying for a new egr valve and used vcds to change the function of the valve. Now the warining light has gone and have realised I used to get around 38/39MPG around town and now getting 32/33MPG! Im guessing the valve is now closed and EGTs have increased, causing more fuel to be taken into the engine to reduce the temp. So is either replacing the EGR valve/ vaccum the best option or for about half the price get a EGR delete kit? Thoughts welcome, thanks
