I experienced a second occurrence of PRNDS flashing from the DSG mechatronics 02E 927 770 AE. I've serviced the DSG filter and fluid, with OE parts, at 40k intervals since ownership. Once at 265,000 and then at 305,000 a couple months ago.
-The first occurrence was August 9th at night from a cold start which immediately set a fault PRNDS flashing and no reverse. It made the short trim home and onto the lawn. The next morning VCDS scanned 18145 - Transmission Solenoid Power Relay. I cleared the code and it stayed off. I was able to reverse. I did some web research and decided to clean the grounds under the hood that morning. One at the right headlight, one at left wiper arm, one at the right headlight including the transmission on both ends. Also the battery ground on the right shock tower. All were wire wheeled and installed with CRC electrical contact cleaner. I also pulled the harness off the transmission. I noticed it was damp with an oily residue, so I CRC'd and aired out the pins, then ensured that it secured back on. No codes came up for about two weeks. Voltage supply 1 and 2 both had 13-14 VDC present. I downloaded the VW DSG 02E self study pdf to get more familiar with the components. Also to note, the selector lever is showing all positions as it is shifted through the PRNDS range in VCDS.
-Second time was today after a 10 minute drive. It cold started fine, drove half way to my destination (2 mi.), came to a stop on my journey and shifted to P and left it running. When I returned one minute later the PRNDS was flashing.......I scanned it tonight with VCDS. VCDS results are below. I cleared the codes, but the fault returns and there's no reverse.
+ I plan to back probe the harness tomorrow to check input voltage at the transmission harness for the voltage inputs. It appears like it's time for a rebuilt Mechatronics. I'm really interested to find a reputable place to send the unit if you know a reliable rebuild vendor. I found a place in the UK that shows $370 + $50 return shipping Ecutesting.com
