I got a A3 3.2, but since most duudes there are 2.0T, I figure I ask my question here.
My AWD stopped working a while ago and I have been driving in FWD for a while. Now winter is starting to come and don't want to be in FWD mode. I have the HPC controller
I scanned my car and it came out with this:
Address 22: AWD Labels: None
Part No: HW0 5Ha lde x
Shop #: WSC 00000 000 00000
1 Fault Found:
00448 - Haldex Clutch Pump (V181)
014 - Defective - Intermittent
It indicates the electrical primer pump being defective. Does that mean if I bring the car in as is, they won't swap out my HPC controller or the valve/pressure sensor that came with it? It would be too much a PITA to swap it out just for warranty service (I have some extended warranty that comes with my auto insurance). Hopefully, I can find a mod friendly shop that doesn't know or care that blue box is a aftermarket part.
I saw this thread where it was just a connector that had to be re-plugged:
I remember there were a couple of plugs that goes to the HPC module, is one of them directly from the V181 Haldex Clutch Pump?
