Be interesting to see how you get on with the clutch, and how much it ends up costing. Might help a lot of people out who want more power, or want to use the cars hard on track.
This sounds very much like my car and has been doing this for years (I always assumed it was the car being over sensitive and pulling the power).So it looks like my clutch pack is starting to let go. I'm told there is a common issue where the rear main seal mists a bit of oil onto the rear friction plate. This shows itself initially with the car reducing boost/power when it sense slip in 5th gear. So I pile through the gears and it gets to 5th and goes slower, shift to 6th and it goes full bore again. You can see the boost pressure drop down to just under a bar then climb slowly with the revs. The cars ecu monitors input and output shaft speed of the gearbox by the looks of it. It is likely effecting 3rd also but as it whips through quite quickly I'm probably not noticing it. We did keep the torque relatively low to try and keep everything together so this leans more on a contamination issue but that said it is now on 98k... Id say on a stock car you would never notice unless looking for it or if it was really bad.
I'm looking to get a stronger clutch made up by helix (through Ktec) to replace the current one, just awaiting a new rear main seal to come into stock before I drop the car off. This will be the first major job I've not undertaken in many years. To do the job the gearbox needs to be fully removed and some specialist tools used to remove and press the clutch pack into the gearbox.
Hopefully it will all go well, then later in the year I can jump back on the quest for power with bigger injectors and a few other tweaks, the clutch will be hitting the wallet a touch hard though.
does it only do it in 3rd and/or 5th?This sounds very much like my car and has been doing this for years (I always assumed it was the car being over sensitive and pulling the power).
it would appear so…does it only do it in 3rd and/or 5th?
could well be a bit of contamination on that friction plate, or just a little worn out with age. does it do it more/worse on cold days, when the car may be a little more fruity/powerful?it would appear so…
He is indeed, hoping to drive out there again soonI run most things past Tuur, he was the one that told me the issue after I ran through the issues and problem solving I'd tried already. Top bloke 👍🏼
so its a hard one to put a definite finger on as some days the car feels like someone has left the stable door open and all but a few horses have bolted. Others it feels great and pulls like it should. My gut feeling is there’s more to to that simply clutch contamination, I think there’s an electrical element to it also. But, I’m just a girl. What the fcuk do I actually know 🤷🏼♀️could well be a bit of contamination on that friction plate, or just a little worn out with age. does it do it more/worse on cold days, when the car may be a little more fruity/powerful?
I can check the thickness of my clutch plates using Renolink, could possibly do similar on yours to confirm the issue (contamination or wear) that said its the same job to fix it.

To be fair, I think the stock clutch will be fine for most people. The price of this fitted (at the moment ) is cheaper than a new unit supplied and fitted, essentially its refurbing and relining the old one. (I've done this many times in the past, just never on a DCT)
We will see though, for me it needs to be able to hold more torque than the stock unit for a decent amount of time to be a success, happy to try it out though and go from there.
I've been quoted just over 1500. That said I've still not heard back from them so fired an email over at the weekend.What's the damage?
Not got any videos of it as of yet. I will at some point though. I had it mapped pretty linearly, so it drives a little more like a big N/A, hard to explain, pulls well though, gets stronger the further through the revs you get.Loved reading this give me some inspiration for mine! How does the new power feel? any videos of it doing some pulls etc?

refurbished clutch, not the box.....Nearly £4k for a refurbished box!!! Just buy another car for that, they seem to be interested in pushing Hyundai and fiat 500's just now. For the work you do on the cars you have had and have, i'd take the pain on taking it out and doing yourself. Easier said than done tho.
glad im not the only one thinking it...That’s taking the biscuit like
Get a shot of a hoist and whip the whole lot out? My neighbour loves doing engine changes on transits (Don't ask - but we've managed to do 4 engines out in a day, a really really long day) Plus get to clean up all the engine and box while its outrefurbished clutch, not the box.....
yeah ive had a look at whats involved, wouldnt be too hard really. if i had a ramp itd be done by now.
I had a purple gearbox bushing in my first Cupra, would have preferred the red or yellow to be honest as the vibrations were a little too much for that as a daily.
