Bye Bye Transmission?

So far so good. Got registration on the car and have put probably 30 miles and no code coming back for the tranny. Before the fluid change and speed wheel cleaning it would come back after just a minute of gear changes. I have to order obd eleven to clear the airbag code and I'll probably get a litre of fluid at the same time and add that to the tranny and reset the level.

Interesting so yours went away after only cleaning wheel and fluid change?
Guess ill have to follow suit and try that out first.

^ These sensors wheels filling up with filings has to be the reason for this type of issue.

Trans still shifting OK 3 months in. It faulted once when shifting into reverse on a hill. It is pretty clunky going into reverse or drive but seems to work OK. It's like it clunks twice then stops. I've never had a dsg so don't know if this is normal behavior. I assume the clutches need replaced at some point, but until then she can clunk away.

If it goes bad, does anyone know the going rate for salvage DSG gearboxes? I was bore and recently looked around for replacement 6MTs and was surprised at how amazingly cheap they are, like.... a couple hundred for a functional transmission.

You shouldn't be surprised at how cheap the manual trans is. It is essentially the same transmission found in every manual golf/gti since early 2000s. 02J or 02M whatever ours is. DSG is way more complex and is essentially two clutches so it's always going to cost more. Salvage DSGs probably go for 800-1200

My reverse problem got much worse over last couple months, was happening daily and on occasion popping a P2711 code "Unexpected Mechanical Gear Disengagement" so I finally got around to cleaning the sensor wheel.

My DSG filter seemed to be disintegrating, not sure why. It was an OEM filter I picked directly up from the dealer.
And the gear oil I used was Febi NR.39070 straight from Germany.

The sensor wheel had a bunch of metal powder on it, but oil didnt seem to have any flakes, or shine to it.
Cleaned it up with rag and we'll see how long it lasts.

Also noticed some rust on the oil pump, hopefully this doesnt cause issues

I used some Valvoline Dual Clutch transmission oil this time since it was only thing I could find local.
So far the cars been driving much better and hasn't failed to engage reverse even once.
It doesn't even hesitate anymore like it did before.

Hi! My 2010 Golf with DSG (around 118k miles) has been doing same thing when I try reverse. Any update on these days after you clean and refilled the oil? Please let me know I would appreciate it!

Unfortunately I still get it on occasion. The immediate days after it was a dream. Im assuming that means the sensor got covered in the fine particles again. I would assume the only way to fully treat this is a complete teardown and cleaning of all the magnetic areas within the transmission

Thanks so much for responding. Ok! I will try it too and readapt the DSG using VCDS after cleaning. Thanks so much again.
