'02 Bora 1.6 AZD 16 valve SE with a new EGR valve fitted. I keep gettting MIL and code PO171 - even though I clear code with VCDS Lite. fault code reappears after either a few days or approximatetly 50 miles. any help will be greatly appreciated. I am located in SE London but am willing to trave to any location within the M25.
Thanks In Advance
