Hi experts,

I have a 2008 VW R32 with a turbo upgrade and it's mated to a DQ500 to handle the power. The gearbox is very young but the problem started with the car refusing to go into R or D. It would grab eventually, hard, and then work fine until you park it again and it gets cold. It has progressed to where nothing I can do will make it grab a gear. In the process, I got the PRNDS flashing warning and codes for Clutch 1 and 2 unintentionally releasing.

We replaced the mechtronic recently and it did not help the performance, although the codes went away. There are no codes on the TCU, and the only codes on the ECU are for changing the battery (steering angle sensor, etc).

We tried to apply basic settings and it fails for "Aborted Safety Reasons" and nothing I can do will make it work. Nothing I can do makes any sound come out of the gearbox either. It seems like it's either not getting instructions or its incapable of any internal movement.

When I put the car into any gear, none of the adv measurement pressure settings change.

Any suggestions on what to diagnose next would be greatly appreciated!

Thanks!

PS - I've verified the gear selector setting is correct in VCDS so that's working fine

I believe so. I drove it about 200 miles and once it would get going it shifted flawlessly and had great power.

The company that did the work also tested it extensively including dyno and road work.

Can anyone explain in simple terms how the pressure is created and controlled to operate the clutches inside a DQ500? I understand there are 2 pumps? a general supply and a hydraulic one inside the mechatronic, is that right? And there are two pressure sensors that are known to go bad, K1 and K2?

Are those readings the oil pressure in the mechatronic or the pressure the solenoid is pressing on the clutch with?

Thanks in advance!

I don't like your freeze-frames having bogus values for vehicle speed (255 km/h) and accelerator pedal position (0% even with off-idle engine RPM and torque) as well as sometimes not seeing RPM.

Your DQ500 has live measuring values for that data, see here for maps of a DQ500 in a RSQ3: https://forums.ross-tech.com/index.php?threads/26685/#post-228249

I would look at those and make sure it's consistently receiving engine RPM, accelerator position, and vehicle speed over CAN. If it's not, then that's an indicator you have software interop issues somewhere in your ECU / mechatronic / ABS combination. In that case, drivability issues are definitely expected, and you're not meeting those safety preconditions for running basic settings.

Thank you jyoung and iichel!

To mate the VR6 to the DQ500 I think there are some software gymnastics required. I know we need a specific vintage mechtronic for the application.

Ill start digging there.

I appreciate you both so much!
