Hi all
So I scanned the car today trying to figure out why my central locking system keeps locking and unlocking at low speed by itself. No faults logged
Anyhooo I spotted 3 engine faults. My first thought after some googling is a possible bad n80 but any input would be helpful.
I’m running pretty much stock but with a DV+

I'm pretty sure that bottom one is the charcoal canister and pipework.
-
First step is to clear the codes and see which ones come back, but the top one could be a sticky DV+. The brass piston can bind in the alloy housing and is why I stopped using that DV.
The second error could be a worn HPFP cam follower, or the sensor on top of the pump could be cracked?
The third error is a pain in the arse and sometimes requires a new N80, new charcoal can, new charcoal can pipe and a new fuel filler cap to completely resolve. Start with the cheaper items first. Some folk also find brimming the tank causes that error, but that's never happened on mine.
