Chasing a fault or faults with my Mk5 R32 that I think are electrical gremlins. I've replaced the timing chains and the VVT solenoids for a short while all seemed well. However recently the car started complaining about the cooling fan and then also threw some codes P0102 and P0113.
It went for it's MOT and failed due to emission's but they managed to get it past by taking out for a drive as it hadn't done much running around for a few months. I suspected battery based on this and as when I took it out the day before the MOT I turned on my heated seat and that seemed to cut the car out! I've replaced the battery now anyway as it was tired and the only codes I'm seeing now that are repeatable are these relating to P0102 and P0113. The symptoms aside from the codes are just slightly rough running and idling.
I'm suspecting loom or MAF itself. Usually i'd just buy a new MAF and see if it sorts the issue but I'm not sure if the previous owner replaced it and I don't want to throw another £100 away on something that might not be the cause. I see some stamping on the body of the MAF 32/06 3A and I'm wondering if this is 32nd week of 2006 perhaps? If it were the case I think a replacement might be a good start but not sure if there's another way to identify if its original to the car or at least older than last few years.
