20mpg

is 20mpg normal?? ive had it upto 26 on motorway at 80mph for 15 miles. but it seems to be going down by the day. lambda sensor has been cut off. but it still shudnt affect it that much surely?

My mPG has suffered alot, i taught it was petrol prices but i dont think so. According to MPG computer it varies from 18mpg :help: to 29mpg, some times im lukcy 33mpg. I have alhambra 1.9 PD TDI with stage P-Torque remap. Past month ago i cleaned the egr valve, then lowered the setting for it...
