Coming across an issue with my Tiguan 2017 2.0, 7 speed dsg auto - 45300miles on the clock.

After 35mins of driving roughly the emergency gearbox mode (you can drive on) comes up and goes into limp mode. I then switch of the engine and it goes back to normal for 20 mins then message comes back.

If I leave the car overnight, it drives fine Asif nothing is wrong until it's all warmed up roughly 30mins of driving then back into emergency mode only gears 2 4 and 6.

My friend plugged it into his basic code reader and fault P0805 clutch positioning sensor circuit came up.

Any ideas what this could be or anyone came across similar issues?

I've read about mechtronic box failure but surely not being 2017 and only 45300 on the clock, and of course out of warranty.

Cheers

It may be something as benign as the sensor itself is playing up. And not the gearbox.
The DSG has 2 clutches, one for odd gears and one for even. Makes the gear change smoother and would xplain why you can only get gears 2, 4 and 6 in emergency mode.
Not seen this mentioned anywhere else here but sounds like a visit to the dealer, but at least armed with the above info

Yeah think I will give them a call tommorow as I've just had a minor service and gearbox oil and filter changed this week
, VW also carried out a health check but never came back with anything concerning but I guess it's due to them not running the car for a long period of time.

Took my car down to a local gearbox specialist an he plugged it in and got the same fault my friend got on his unit and says as the fault is intermitten it's likely the Mechatronics box is on its way out ! ...and mentioned the clutch positioning sensor itself it's within the Mechatronics box ! Not what I wanted to hear...a new box itself is +/-£1850 without vat and fitting, such a strange fault tho as it's driving fine yesterday Asif nothing it wrong...then a long journey it will ping up about 40 mins in

Guys for what it’s worth……have a look at getting VW’s extended warranty! These cars are great when in the first three years and under VW warranty but can be an utter nightmare when that expires! I have the extended VW warranty on my 2018 R line biturbo, mind this was post having to have a failed LP turbo replacement at 3K…ouch. For £33 a month you get x two services, VW warranty, breakdown for two years and x two MOT’s…plus you can sleep at night not having to worry which black box/item is going to fail next.

Hi, did you get to the bottom of this? Mine has just done the same thing. Same year 2017 - similar mileage. I’ve read it’s a really common issue but can’t be seen until the end of the week so no car whatsoever and my commute it an hour each way so that’s great. Also how much did this set you back to repair? Thanks

I'm located in Australia. We first had the warning 'Gearbox in Emergency Mode - you can drive on', January 2021. Took it immediately to mechanic (who works with European cars only) and he checked it and found it to be caused by a battery fault. So, battery replaced, faults cleared and no problem again even after a long drive in April 2021 of about 500 km.
This Monday, 21/2/2022 on our first long trip due to being restricted with COVID rules, we set off for a 1,000km round trip and at about 400 km the dreaded warning light appeared again. Had to stop several times along the way of the first stage of this trip and restart car to clear the light. Then engine light came on and cruise control ceased working.
No dealer was prepared to look at the problem, so we were left with no choice be to continue another 80 km approx to our first overnight stop. Remember Australia's towns are spaced much further apart than England's. At this stage we could only travel at a max speed of 67 km and only gears 2 and 4 would engage.
Long story, short - Roadside Assistant man said don't drive any long distances (that put returning home by car out of the question) and that it the error that came up showed P0805 Clutch Position Sensor Circuit (after being stationary four about 4 hours). So the car was placed on a tray truck and shipped home and we flew. Thankfully we have roadside assistance which covered these costs ------- but we still need the problem fixed.
Seems to me, from reading the many forums that the Mechatronics is a problem known to VW but they will not recognise it to enact a Recall of vehicles.
I have my fingers crossed.
Put me down to add to a Class Action!

Hi, my 2017 tiguan is doing exactly the same thing, drives me nuts. So intermitant. But once it happens that's it until you leave the car off for about 12 hrs otherwise it happen every couple of miles.
I was wondering if it was water in the electronics?
At the point I'm just going to sell the car unfortunate because I really like the car.
Absolute joke a car with such little miles can have a fault that vw aren't recalling because it's a common fault.

Any informations about fixed/faults found would help? Maybe stop me selling it. Absolutely bricking it putting it into vw with there hourly price to find a fault on something that happens know and then. May never find the fault at the right time but will still charge.

Cheers guys

What are the cables you mention?
A little knowledge can be dangerous. This article's about the DSG box, controlled by the mechatronics module physically attached and integrated.

The reply about the cables is referring to the manual box as the gear shift is connected by cables with poor joints, so can cause miss selection.

I wrote about this problem in February. It was only when we forced the error to appear and were able to get the VW dealer to read the code immediately that it was confirmed as the mechatronic unit being faulty.

In Australia we have protection through the Australian Consumer Law, which covers major failures for items where it is expected that they be “good for purpose” for a period of ten years. So even though our warranty period had expired for our 2017 Tiguan, we made it very clear to the dealer that we knew our rights, and that the dealers’ call was on VW for a replacement part and our call was on the dealer for cover of labour to fit the part.

Thankfully there was no argument and the part was replaced last month at no cost to us.

We still have to go for a long drive the test the new unit, and plan to do that in about four weeks.
