Hi guys, I recently had my car mapped and have come across some challenges. So the mapping to be fair did not quite go as well as planned, a few points were picked up including my fuel pump seems tried (its only 11 months old - (1J0919051H)), the MAF was knackered and the N75 is erratic. Before dropping the car I did a fault check and it seemed to be working fine and I am guessing when you start pushing the car faults can/will arise. So when I collected the car and drove home, I got a light on the dash so I checked for fault codes. I got the below 16486 - Mass Air Flow Sensor (G70): Signal too Low P0102 - 35-00 - - 17963 - Shareware Version. To Decode all DTCs P1555 - 35-00 - Please Register/Activate Readiness: 0010 0101 01314 - Engine Control Module 79-00 - Please Check Fault Codes 00290 - Shareware Version. To Decode all DTCs 04-10 - Please Register/Activate - Intermittent 00287 - Shareware Version. To Decode all DTCs 04-10 - Please Register/Activate - Intermittent 01324 - Control Module for All Wheel Drive (J492) 49-10 - No Communications - Intermittent I got out the trusted laptop and cleared the codes down but these are still in the ECU. 16486 - Mass Air Flow Sensor (G70): Signal too Low P0102 - 35-00 - - Readiness: 0110 0101 01314 - Engine Control Module 79-00 - Please Check Fault Codes So I managed to get a genuine Bosch replacement MAF, but I am still getting the same error codes 16486 and 01314 even after clearing the codes again. Do you need to do anything when you replace the MAF like adaption? I checked the MAF plug and it does not look the best so this will need replacing I guess. While going through the fault finding, I decided to take a look at the N75 and both part numbers are completely different. 058906283F and the replacement is 06A906283E, which is the right one both look suitable from googling and does it matter? To add to all this my management light has come on. So not a happy bunny. Feeling a bit feed up.
