Regarding mileage. I've got a 2011 2.0 TDI 170bhp DSG VW CC with 260k miles on it. Had it 8 years. Routine service and DSG service keeps her going. Things changed/fixed: Front wheel bearings, discs, pads, tyres, couple of bushes Dual Mass Fly Wheel. So nothing out of the norm for routine wear and tear and it never misses a beat. My 2017 2.0 TDI 190BHP DSG superb has 400k Km on it. Had it 3 years. Things changed fairly much the same as the VW CC, As others have mentioned. Routine servicing including DSG and they will do very large miles. I've read of some 2.0 TDIs hitting 500k miles.

I scanned the car for codes. The one I got was: P029900, Turbo Charger Under Boost

Anybody?

Hi All, I've got a 2017 2.0 TDI 190 BHP DSG sportline. A couple of times now over the last 2- 3 week when I've dropped the DSG into Sport and hit the accelerator to overtake a car I get a flashing coil light and the car goes into limp mode. Stop the car and restart the flashing coil light goes out and car goes back to driving normal. I did a quick scan with Carista and have the code P029900, Turbo Charger Under Boost. Doing a bit of searching / googling I've found a couple of possibilities: 1. A check valve on the vacuum line: 2. Turbo actuator: Any other ideas what it could be before taking the car to the Indy? I'm planning on trying 1. above as it's only a few quid for the part and an easy change. Thanks.

Rather than replace the slipping clutches have you looked into can the pressure used to operate the plates be adjusted. I ask because a VW/Skoda Indy had mentioned this to me before. About 3 -4 years back I had my 2011 VW CC 2.0 TDI 170BHP with the DQ250 DSG into them to get the Dual Mass Flywheel changed. So I asked them as they were doing the DMF should I get the clutches done at the same time (car was on about 220,000 miles at the time and on the original clutch pack). They said no and that they had never had the need to change a clutch pack on a DSG. If the clutches did start to slip they could increase the pressure used to operate the plates using VCDS to stop the slipping. My VW CC is now at 260,000 miles and still on the original clutch pack with routine 40,000 mile DSG oil changes. Might not apply to a DQ200 box but might be worth looking into to save a few £££. There are also videos on YouTube about how you can use VCDS to carry out adaptations on the DSG where the clutch re-learns "bite" / engagement points. They might be worth a look as well.

Where in Ireland are you? Might be worthwhile giving Daltons just outside Portlaoise a call if you're not to far away. www.daltons.ie

@Donweather It was a four wheel laser alignment where it measures all the angles. So I'd say the camber on the rears was checked. As mentioned earlier in the thread, small adjustment made on the rear drivers side. I think when I replace them (next few days) I'll try rotating tyres periodically as mentioned earlier in the thread to see if that helps. The current set had done approx. 32k miles before I noticed the rumble noise starting.

When I got 2 new tyres a few weeks back I got a four wheel alignment check done. Rear drivers side was out slightly but not much.

@langers2kWondering if you can help here. When I got my car a couple of years ago the memory buttons for the seat worked fine. One time when moving the seat all the way back to hover underneath they stopped working, I followed the move forward, back, etc. and it reset. Then a e while later the same thing happened and no matter the combination of forward, back, up, down, etc. nothing would reset it. Using VCDS I ran the basic settings a number of times but nothing seems to get rid of the error codes. I've taken some photos of VCDS to show what I get. Error Code 1: Error Code 2: Error Code 3: Module Info: Advanced Info: Thanks.

I've got a 2017 2.0 TDi 190Bhp Combi and run 2.5 bar on all corners as usually there is only two people in the car. Do you think increasing the rears to 2.8 bar might reduce the issue I'm getting with wear / cupping on the inside edge of the rears?

I have the same problem on mine and tried the different options mentioned in the various threads. I even tried using VCDS to reset and complete the normalising (I think it is called) where the seat automatically moves through all movements. Still no joy. So resigned myself to just moving the seat manually. Error code I get is something like lumbar movement missing basic settings.

@toot I had read that the recommendation was to always put the new tyres on the rear. Hence moving the new tyres to the rear and putting the old ones on the front. I'll see how it goes. I'll probably end up getting new tyres on the front as well .

I had the same sort of issue on my 2017 190tdi Sportline combi. Inside edge of rear tyres wearing. Cupping I think it is called. 4 wheel alignment done and the rear drivers side was slightly out but not much. Shocks are Koni special actives and only about 2 years old. I'd to replace the front springs just over two years ago as the drivers side snapped. Rear springs are the originals. I don't carry heavy loads (at least not often) and I don't have a tow bar. Could it be worn / saggy rear springs causing the issue with the rear types cupping? I've rotated the wheels for now so the new tyres are on the back and the old cupped tyres are on the front. A bit of extra road noise from the front but hopping that will go as the tyres wear.

Here in Ireland we can get Dipetane. Not sure if you get it in the UK or not. On some forums you will see people saying that when they put their car in for its NCT (Ireland version of the MOT) if failed the emissions test. Then after running the car for a period of time with Dipetane in the diesel it passed the retest no bother. Also threads saying the NCT tester recommending using Dipetane to get cars passed the emissions test. It's a Hydrocarbon fuel treatment that is supposed to make the fuel burn more efficiently reducing carbon and emissions. https://dipetane.com/

I've a 2011 VW CC 2.0 TDI 170 BHP with the DQ250 wet DSG (probably the same in the sportline you're looking at). It has 240k miles on it and still on the original clutch pack and never had a problem with the gearbox. And that's after getting the engine and DSG remapped 7 years ago. I've also got a 2017 2.0 TDi 190BHP superb sportline with the DQ250 wet DSG. I had the engine and DSG remapped 2 years ago. Now on 400,000Km. Original clutch pack and never had a problem with the gearbox. Just make sure the DSG oil and filter change has been done every 40k miles.
