Alright! So after the dealership being a total waste and telling me what I already know, these are the results.
As posted on the scan, my vehicle has a CTHD ECU.
With only 65,000KM, and all harness and connectors intact I was pretty sure that the wiring was not an issue.
My fault was the P10A0 - Electrical Malfunction on the Air Recirculating Flap.
My issue was the ECU. There are two options to get this sorted.
1. Have the ECU replaced with one with the EXACT part number printed on it. Ending letters MUST be the same and have it coded to the car. The shop or person must have VW dealer tool to properly have this done, however the issue will return as this is a known fault for these vehicles in this climate.
Or
2. Repair the ECU. I had no choice but to go with this option as I was unable to locate my ECU online or locally, and also, the option of brand new was costing over 3000USD which was not feasible for me.
Repairing the problem:
From looking on, apparently there’s a capacitor that burns for whatever reason due to the circulation flap as it’s connected directly to the ECU. So that was replaced and the track from the pin for the circulation flap to the capacitor was also burnt. It was damaged pretty badly. So that was repaired. After this, I cleared the fault, and I can now go over 3000rpm.
So this is the solution. Once your connector to the flap is in good condition, and you changed the flap but the P10A0 fault is still there, it’s the ECU.
Hope this helps someone in the future.
