Hi,

I got a 2017 Tiguan 2.0 TDI Bluemotion and I got clunky downshifts on uneven gears.
I got an extended warranty through the AA, and I was wondering where you recommend I send my car to get it fixed.
To be clear, no faults have been generated, but I don't want to wait until I am actually stranded somewhere.

Hi mate,

Is the AA extended warranty a full third party warranty or the Garage Repair cover?
If it's the latter, the must cause a breakdown and you must call a patrolman out to diagnose.

Hope this helps

After driving my 18 plate diesel for about 30-40 minutes, it goes in to gearbox safety mode. I’ve had it for less than a year and it has 54k on the clock. Took it to a garage who read the code and said it’s the mechatronic unit and it will cost 2k for the replacement part not including labour and other parts. I’m gutted. It such a big expense for a car with a relatively low mileage. Also, the garage told me this is a very common problem on Tiguans. I can’t help feeling VW know about this issue and are not owning up to it. I read in Australia they had a recall on the same part. I’d be interested to know how many other people have had the same issue?

That's a shame
Have a read of other threads on here, as there are other options like getting a refurbished unit.

If you could find an independent garage near you to fit it

While it's a not uncommon issue, it's not what I would think is endemic. Given how many VW cars have a DSG box the number of problems is in the very very low percentage.
None of which helps you of course
Hopefully someone on here can advise a best course of action.

Looks like a good option. Thanks

Thanks. I spoke to these guys and they quoted me about £450 to repair the unit. Seems reasonable and much cheaper than some other places have quoted. Have you used them before?

 

[thejanners]

No I haven't, but it was being investigated prior to me buying the Tig as friends of mine were having issues with there DSG although they did have older vehicles in the VW group
I took out the extra warranty after the 3 years was up as I am finding it difficult to work on my cars due to space even though I am able bodied to do so

Four days ago we also had a problem- the gearbox in emergency mode notification came on. VW quoted just over 1.6k for the "gearbox repair kit" and then confirmed it's mechatronic unit. We are no happy as our extended warranty just finished in Jan and we were planning to get a new cover, but none of the telephone advisors knew how to extend as it's different for cars over 6 years, so we left it to speak with the vw garage, as the car was booked for service and cambelt change in the mid of May. The mileage is only 51k, therefore we are quite disappointed with the expensive repair and no car for further 2 weeks. Tiguan diesel Estate, 2.0 TDi 190 4motion R-line

The increase of this fault with the mechatronics unit is concerning. They all seem to go around the late 40’s early 50,000 miles. @pa.paulina the fact your extended warranty ran out just before it went is horribly unlucky and Sod’s Law, I feel for you. As you have to pay, it may be worth your while going down the repair route from these guys as mentioned on here before. Will save you a lot. Keep us updated on what you decide and costs please.

My tig was on 63k miles when I sold it, the box performing perfectly. There are a number of variations of the DSG gearbox, maybe if people gave more information on their specific car this could be narrowed down to a version of DSG.

Mine was the DQ500 high torque version fitted to a 177 ps diesel 4 motion.

I agree but @pa.paulina listed her Tiguan at the end of her post as being 190 TDI 4motion which will have the DQ500 also.

had a chat with my local vw specialist, he does alot of work on dsg boxes.

he says vw dealer replace instead of repair, hence the huge costs. Should be no more than £400 to repair.

I have a 2018 plate Tiguan 2.0 biTDI 240 and at 60,000 got the mechatronics failure. Currently at VW garage getting sorted under warranty. Been there 2 weeks. No news yet

I have a 2020 VW Tiguan where I had a problem with the Megatronics. Exactly the same pattern of error messages etc which was initially cleared by computer then happened again and VW said the entire gear box required replacing. I lodged a formal complaint with VW given it is less than 4 yrs old, just out of warranty and low mileage (55k). VW came back and stated the issue was caused by my “Driving Style” - I am lodging a complaint with the South Africa Motor Vehicle Ombudsman. I had the megatronics replaced by a a gearbox specialist at 1/3 of the cost but am likely to sell the vehicle now. I find VWs feedback unacceptable. Driving Style?

Also by the number of votes on this forum it looks like this is a potential issue?

 

[Tricky]

It's happened to a few people, but considering the millions of DSG cars out there, and the hundreds of members on here with DSG'S it's not a major issue.

I agree with you totally on the VW position: A manual clutch you could cause issues driving badly, DSG totally down to the car, you just accelerate and brake, the car does all the gearchanges not you.

P.S. It's meCHatronics

Thank you. As you can see I am not a mechanical expert anyway have replaced the mechatronic plate and all seems fine now. Just irritated with VWs feedback that’s all.
