Emergency transmission mode

[akajjo]

I had weird experience.
2018 Highline 26000km
I got warning message
Emergency transmission mode, You can continue driving
then car used 2nd, 4th, 6th gears only with high RPM
After 4hrs I restarted it and I drove normal but there was engine light on
Next day, warning disappeared
Does anyone have same experience?

Take it into your local independent for a scan.

Given that a 2018 car would still be under warranty, why would you not just take it to a dealer?

Yeah that's odd. I would assume the gearset/clutch pack that houses gears 1,3,5,7 has an issue and that's why it disabled those gears. If you do not understand the DSG transmission, it has 2x gearsets inside the transmission - one controls gears 1,3,5,7 and the other controls gears 2,4,6.

Good thing is that your near new car is still under warranty - so make sure you get VW to have a good look over it, and if nothing else, have that issue recorded against your cars records incase it comes back again outside of warranty.

There are 2 mechatronic units one changes the odd numbered gears 1,3,5 and 7 and the other changes the even R, 2, 4 and 6. When one of the mechatronic units it can still use the other one, just not shifting to gears controlled by the other unit. This also triggers "limp home" mode in the engine management, if you turn off the engine completely (not just hit the Engine Start button) then it will reset the "limp home" mode for a short time so its easier to drive.

Strongly suggest you take it to a dealer and they can run diagnostics which will confirm the issue. From what you have posted it looks like the odd number gears mechatronic unit is on the way out or it could just be something simple like a loose electronic plug on it.

There is only ONE mechatronic unit and two clutches

So I've just had the same thing happen. I was 200kms away from home too, so driving back involved stopping a fair few times and restarting to clear the transmission errors.

I've booked it in with Volkswagen. Unfortunately mine is now out of warranty so I think I'm going to be hit with a massive repair bill. Not looking forward to that at all.

This is my third VW with a DSG so I guess it was a matter of time before I had a DSG issue.

I think you’ll be covered- assuming it’s the 2017 in your signature AND it isn’t modified.

No gearbox servicing happens in the first 3 scheduled services- so not even a ‘bit maintained’ angle could get VW off the hook. Because they feel it has 4yrs/60000kms minimum life in it- you should have a positive outcome.

Well, I had an APR stage 1 ECU tune (not DSG) done a few months back. I'm getting that reverted to stock tomorrow before it goes to the dealer. I know that it's possible that they can check the flash count so I could be in a spot of bother. I've never done a tune before because I've been paranoid about this type of thing happening but decided to do it this time because i found the car really lethargic in certain scenarios.

I'll see what happens..

[Simonr23]

Morally/contractually you shouldn’t be covered (the price you pay for playing) but if they don’t check- good win for you.

I don't have any moral issues with it because I seriously doubt that the tune would have contributed to the issue and I really don't drive the car hard at all. But yes, I did take the gamble in tinkering and if it means I have to shell out for it, then I'll take it on the chin.

Funnily enough, I was getting very close to purchasing a Golf GTI to replace my wife's car, but if this is going to set me back $5-10k then that goes out the window.

Hopefully you end up with the GTi

Just had the same problem with our '17 140TDI, only it was the other gearset. So no reverse gear. Car has done 72,000km. We were also 300km from home so that was a fun trip back.
Dealer has pinpointed the mechatronics unit to blame, waiting to see if VW will cover it as its 3 months out of warranty.
They noted that we own another VW and said that might help our case, fingers crossed.

[Simonr23]

You’ll 100% be ok- if you’ve kept the car serviced.
The dealer already knows this too- just wants to get some brownie points by “putting the pressure on VW Aus”

I'm waiting on the claim response from VW as well. The DQ500 is meant to quite good and to date has apparently not had many issues, but I've seen several reports in various online forums and facebook groups about people suffering the same problem and requiring mechatronic unit replacements or repairs, literally all in the last 2 months or so, on 2017 model Tiguans.
