First Post, Thanks for reading and helping out. Here's the story:
-At 91,000 owner (me) performed DSG fluid and filter change, 5 liters Pentosin and filter.
NOTE: Last DSG service was at 37,xxx miles, so I was way over the 40K service interval with 53,000 on that fluid.
During process, on VAG com noticed:
19221 – Clutch
P2789-001 Adaptive Learning at limit – intermittent
(I can post the print out of this code with measure blocks if needed, it won't show on autoscan because I cleared it)
Cleared code
-Drove car for a week or two, noticed buring smell, slightly jerkier performance (car never seemed smooth to us at times)
Same code re-appeared
-Performed another DSG fluid change to verify correct fluid level. This time with Liqu Moly product. Also performed VCDS transmission reset to basic setting process at same time.
Immediately after fluid change and reset, car popped out of reverse, flashing “PRDL” on dash, this code appears:
18223 – Pressure Control Valve 1 (N215)
P1815-008 Short to Plus – MIL ON
Repeated reset process and tried to move car further, same results but will throw another Pressure Control Valve 2 code.
Attempted to perform another Reset, this time at first group 061 measuring blocks not even visible, just ERROR in boxes.
Disconnected battery and joined positive and negative cables overnight to do hard reset, no change in condition.
Pulled connector plug to transmission, pins look perfect, everything dry and like new.
Took this Autoscan, then took it to dealer to help me diagnose it...
Dealer says bad Mechatronic (Mechtronic?) unit. Seems plausible based on my research, but I don't trust dealer's diagnosis 100%. So I decided to remove Mechatronic unit myself and ship it to UK ECU Testing.com for testing and repair. Once I had it out, I OHM tested all the solenoids I could get to, and all were in what I considered agreeable range. Pressure Solenoids N215 and N216 both showed 4.9 ohms. So I thought sure I had an internal wiring or circuit board failure on the Mechatronic
Unfortunately, ECUTesting cannot find fault in my unit. They put it on a dynamic testing rig and said it performs perfectly. They said my pressure solenoids could be intermittantly bad, but I don't think that sounds right based on the communication problems with my Mech unit.
I talked with dealer and it looks like they did no electrical testing at all.
So I guess I'll pay to have my old Mech unit shipped back across the world, and start pinning out my wiring harness on the car? (as should have been done in the first place.)
Anybody have any other thoughts? I will need access to a FSM or at least a wiring diagram for this car, so any links to that info would be great. Any help/thoughts much appreciated!
My thoughts are a chaffed wire in harness that shorted during basic settings proceedure due to longer duration of solenoid engagement, or maybe running crappy dirty fluid corrupted the trans in ways I can't know or something.
