i put my car on the road on saturday and on sunday the eml decided to light up and stay on.my trusty code reader has decided that it would not read the codes,i could access other areas just the codes i could not read,i managed to get someone with opcom to read the code and it was egr,i already had the blanking plate in place with the egr valve plugged in,so this evening i have plugged the cheater in but i had to clear the code with my reader (yes it will clear codes) and when i started the car no eml on so fingers crossed nothing else will go wrong,just got to fix the roof now
