bought this 2014 a few weeks ago with 34k miles. super pumped about it, 1500 miles later my mech unit goes out and the shop said my whole trans needs to be replaced apparently there were other failures inside the trans. the dsg service was done at audi in florida 4k miles ago. how does something like this happen? it’ll be covered under warranty so im not too worried but just curious how it could happen at such low mileage

Pic for attention. :)

I have a 2010 S4 with 215,000 miles on it. Regular DSG service every 40k miles.

I've got the problem where once the transmission is HOT the car will slam into first gear at a stop, act like its never driven stick before when pulling away from a stop, and only once did it stall when coming to a stop. I only have one code that I pulled a couple of months ago when I actually got a gearbox malfunction display:

8957 - Clutch 1
P17D6 00 [01100101] - Pressure too High
Not Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Priority: 2

Accelerator pedal position: 0.0 %
Clutch status: Kupplung 1 kann Moment übertragen

I have never had any electrical fault codes related to the transmission.

Someone at Audizine once suggested a particular gasket known for causing fluid to leak between galleries but in iterating this with the robot (Claude), it pointed out that the code is for pressure too high - not likely with a leaky gasket. I also considered the ECS rebuild kit but it seems to be focused entirely on the circuit board and I have fortunately never had an electrical fault.

I was considering replacing the mechatronics with a rebuilt unit - there's one or two places that appear to do that by mail - but I let the robot talk me into considering just replacing the solenoids, two for clutch pressure and one for line pressure/cooling. The cost for that will be about $350 or so plus the service kit (which I need to do anyway). That's pretty attractive as I am comfortable doing the work and I don't have to trust that someone else has done it right - that being said, a rebuilt mechatronics would conceivably have new solenoids and be plug and play, too - and would add minimal time to the service project.

Looking for some input here from those more knowledgeable about the transmission. Thanks.

So through my research on this I've been seeing that a lot of people are just straight up replacing the lens instead of trying any box restore products or wet sanding. I bought a cheap turtle wax headlight kit to try and I think i understand why changing them might be the way to go. Most of the "gunk" or imperfections are on the inside of the lens. I'm wanting to know if anyone has gotten any restore kit to work, which one of if so. Or do I just get new lenses? The second option seems to be the easiest option, but the most expensive. Thoughts?

This sound like a flex plate problem or something really bad 🤦🏽😂 ?

This sound does go away when driving too, but comes back when idling.

Timing chains good no rattle.
Transmission feels tight and real good, smooth.

The sound is coming from the bottom of the block at the back…. Scary stuff i know right.

It cant be a starter problem, or debris in there. ?
Anyone dealt with this type of noise, some enthusiast has dealt with something like this before… Come on bro give up the sauce.
