Ive heard that dsg gearboxes can suffer from mechatronic unit failure, is this a common thing?

Im thinking of getting Cupra 290 and would prefer a dsg if they are a reliable gearbox?

Early models maybe had known issues but I know quite alot of people who've had (or still have) DSG based cars and they swear by them, myself I have a 290 DSG and its a great car, well pleased with it especially with the ACC combination.

Its the same as anything else, your mileage may vary..........keep it serviced at the recommended intervals, use it as specified in the manuals, ensure you use a reputable and decent outfit to get it serviced and you will be fine. ;)

I was wondering about DSG also as I really want to go auto on the next car, wasn't there a wet and a dry gearbox or something and the older ones had issues?

The dq250 in the Cupra is "wet".

There was an issue with some early DQ200 7-speed units. The synthetic transmission oil became electrolytic/conductive, effectively causing a short circuit in the mechatronic unit and leading to a catastrophic failure.

VAG issued a recall to refill with mineral oil as a precaution.

Cupra models have the DQ250 6-speed transmission and are not affected.

My Ibiza Cupra had the 7 speed and this box is well known for being not as reliable. The 6 speed is the better box which is also stronger.

The 7 speed in my wifes 1.2 is not as smooth or as fast as the 6 speed in my Cupra. It drives me and her mad how long it holds onto 2nd gear, when 1st is needed for pull away.

Could not agree more. My wife's 2016 Polo Blue GT has the 7 speed "dry" box - it is definitely a good option for the car and I would not buy one without it, but the 6 speed "wet" box in the Cupra is in another league. It is faster, smoother and the shifts are spot on.

The most annoying feature of the 7 speed box is that it shifts to a low gear and holds on to it when you drive on a road with speed bumps. As there are a lot of speed bumps in our area the consequence is that it holds the gears up to 4K rpm on a stone cold engine even though you apply a minimum of throttle. The only way to avoid that is to shift it manually and be extremely careful as it does not shift instantly when cold - which we do to avoid the high engine speed before it is up to temperature but it is a constant item of irritation..

The best future of the 7 speed box is the gearing in 7 - I would wish that the Cupra had that extra slot in the box and were cruising at 2,500 rpm at 140 km/h instead of 3,000 rpm in 6...

Yes miss this on mine, a 7th gear would make the Cupra a very good cruiser.

I have a 2014 Leon Cupra and that had a new Gearbox/Clutch in Sept 2016. I googled the symptoms the same day and the same exact process happened in a 2014 Golf GTI, error messages etc. I've just put it down to bad luck. As people say there's 1000s of cars out there.

Cupra 300 has 7 speed dsg.

No unfortunately not - at least not according to Seats own specifications at Seat.de

To the best of my knowledge vag has no 7 speed dsg that can handle that level of torque from a transverse mounted engine. The Audi 7 speed is for longitudinal mounted engines - correct me if I am wrong?

Ahh it wasn't in my head....I had a DSG 6 speed in the Leon TDI, very smooth, no vibration felt when setting off from standstill, changes ratios very German like...smooth and fuss free...now i have the 7 speed DSG in an Ibiza EcoTSI, rattles between base rpm till about 2k rpm (like in a manual dropping the clutch), changes ok, if not a bit more franticly...like...'arrgghh so many ratios, grrr'

And I thought all DSGs shifts equally :blink:

The DQ250 6-speed transmission in the Leon Cupra 280 / 290 is a wet clutch unit. It is extremely reliable, with only a handful of reported mechatronic issues based on my research.

I was the same as you worrying about it. I purchased my 280 at 18,000 miles and it's on 38,000 now. It hasn't missed a beat and continues to perform as new. I do have mechanical sympathy for it though - I don't let myself launch hard. I take the simple view that if you look after it, then it'll last you well. I'll be getting mine serviced soon too.

There is the DQ380 7 speed wet clutch, think it's only for Chinese market at the moment, max torque of 380nm, apparently there is a version of it called the DG381 (400nm) which the Golf GTi (and S3?) are meant to be getting soon.

The TTRS (and RS3) uses the DQ500 7 speed wet clutch box (500nm).

Hopefully these newer 7 speed wet clutch boxes will find their way in to the Leon Cupra at some point!

New A3, Tiguan, Kodak and Ateca models have a high torque 7-speed DSG.

It's probably not unreasonable to assume that most of the 2.0 litre petrol-engined cars across all VAG brands will receive this box eventually.

UK configurator for Cupra 300 ST 4drive shows 7 speed DSG.

Edit - to be exact it shows 7-speed-DSG in large bold letters however in the small print it shows 6 speed. Nothing new for SEAT.co.uk to show conflicting info on the same pages.

"2.0 TSI 4Drive 300 PS 7-speed DSG-auto
Petrol / 6 Speed Gearbox DSG-Auto / 4Drive"
