any update? I'm gonna try to tackle this issue soon with OBD11, even if it costs me a stupid membership fee or whatever
Apologies for the delay in checking back in on this strand.
So, back in early Nov of this year I ended up trying claytoncamilleri100's suggestion, above (i.e., using the "live data" to adjust my radar alignment to at least be under 0.8" misalignment, parking my Golf R in front of my white garage door with exactly 1.2m between the door and the face of the radar sensor and running the OBD11 module scan) and was able to clear the faults and get ACC working again. However, for the past couple of years (for reasons I still can't figure out - perhaps an exposed wire in the radar harness), my ACC tends to stop functioning for days (and sometimes indefinitely) after I drive in the rain (regardless of whether or not I tried to use ACC in the rain). That is exactly what happened in mid-Dec, requiring me to re-run claytoncamilleri100's process again.
Unfortunately, this process is still a bit baffling to me - this last time I had to rescan all of the modules, select "key off restart" (that might not be the exact name), and clear faults on the ACC module, all multiple times, before it cleared the fault(s). There's likely a more streamlined process of entry selections, but at this point I'm a bit like a monkey at a typewriter every time this issue comes up...
I hope this is helpful to y'all...
