Gearbox in emergency mode Tiguan 2017

[Delewin]

My 2017 162 TSI Highline (70Km travelled) has just started to show this error message, and I was stuck in 1,3,5,7 with no reverse. We travelled from Sydney to Cataract Dam. It was a hot day. After sitting at the side of the road for about 10 minutes we were "back to normal" and able to gently drive back home. I ran a scan when we got back from the first trip and cleared ALL fault codes to try to eliminate erroneous error codes. That was on 9/2/25. Everything seemed fine until 1/3/25 when we travelled to Campsie from Chatswood. It happened again. The same error with no reverse and only 1,3,5,7 manually selectable gears.

Also just had it serviced where I replaced the battery with a new AGM battery. 24/2/2025. Is this a factor?


After the Campsie trip, I carried out a scan (VCDS) and it showed

1 fault found.

I live in Artarmon. This car is well out of its warrantee period. I did the first 6 services at Alto VW Northshore in Artarmon and the last 2 services at Tyre Power in Artarmon.

What are my chances of receiving a good will Mechatronic replacement from VW?

It is bog standard in every respect.

Which VW Service franchise to i use, as I have read very negative feedback regarding virtually every VW outlet?

The problem seems to be temperature "sensitive". That is on a hot day going for a reasonable run, it will trigger the problem. Has anyone "received" the Software Update and was it successful?

Every assistance gratefully accepted.

Thank you,
