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.

Maybe you should try to change cables first, i know a guy who had similar problem and after all it was cables not a Mechatronics box!
