Hi Had my first one of these appear today. MIL on and code indicated faulty EGR circuit. Did the usual clean and test and all seems Ok. Cleared codes and road tested, no code returning but still gutless. Anybody got any info on correct actual values at idle for air mass & EGR, this one says about 38 KG/HR and the EGR is at 35% - Not right to me. Maximum reading from air mass while under full load on road test was about 280 KG/HR- not right either. Nothing obvious. Any common faults to check for on these?
