DSG Transmission Problem

Hey guys, Iím hoping you can help me out with a little problem going on in my car.

So sometimes, Iíd notice that when I put it on drive, it would of just rev. The white letter indicating he gear would start blinking on the dashboard too. Also Sometimes, this happens when I put it on reverse too, it just stays stationary and I have to turn the car off and back on to make it work again.

It showed P0783 (3-4 shift) at the time and I thought maybe I need to add more transmission fluid, so I did and it helped out. It stopped with the blinking white letter and staying stationary, for a month or so. Recently, it started doing it again. The problem is, the shutting it off and turning back on to make it work isnít fixing the problem.

I checked for codes and all of a sudden it showed 4 more codes, and the previous one.

P0747 (pressure control solenoid a stuck on)
P0871 (1-2 shift)
P2096 (post catalyst fuel trim system bank 1 too lean)
P2196 (O2 sensor signal stuck rich bank 1 sensor 1)

Iím gonna try to take it to the shop tomorrow if they have space for me but what do you guys recommend me do? any of you experienced with these problems?

RIP mechatronics unit.


You'll need a new one, and depending on how long it's been doing this for, you might as well look at clutch packs. The cost is typically around $1300-1750 for independent shops, and $1800 from the dealer for just the mech unit, and probably another $1500 for the clutch packs, if not more. Shop around a bit, but I guarantee that's what it is.


Also your post-cat O2 sensor is dead, replace.

Same thing happened to me when the Mechatronic unit in mine went out. Luckily they didn't find any damage to the clutchpacks, so $2,200 later and she was back on the road. I'd stop driving it immediately though, I've seen some instances where a bad mechatronic unit can cause damage to the clutchpacks and require an entire rebuild.

Good luck playing with fire lol. The previous owner skipped the 40k service on mine and the mechatronic took a shit around 58k.

The oil itself is unbelievably expensive, had mine changed now on Monday, but what a difference it makes, do it do it do it... It's like a new ride, honestly.

55k miles without a DSG service yet and Stage 2? I hope it fails before you ever try to sell that car to some poor soul.

OP, yes sounds like a bad mechatronic unit.

Sure can, but how's that labor total look, and what would the lifespan average?


Used part... no warranty, no guarantees. New part, 1yr warranty, peace of mind.
