I have a 2004 Golf TDI (automatic) that recently started having an issue with "low/reduced" power. The car turns over and starts fine but power is low/reduced until ~2600rpm is reached, then it performs ok at all speeds/rpms (e.g driving in stop and go traffic). Performance remains ok as long as I don't turn the car off. There are 2 error code: "Unexpected Voltage" and "EGR excessive recirculation".
With the MAF sensor unplugged, there is no low/reduced power after start-up and overall performance is ok. The "EGR excessive Recirculation" error remains however.
What do you think? Is it a bad MAF? or something else?
