After 5 years of driving my car with no clutch issues, I recently started noticing clutch judder when pulling away. This normally happens on cold and damp days, takes about 2 or 3 times of using the clutch first thing in the morning, then the issue goes away.
I suspect it is a combination of normal wear and condensation forming on the flywheel, which result in a clutch slipping a bit. Anyone knows if the clutch allows some form of adjustment to compensate for the wear and to increase pressure, thus avoiding occasional slippage?

What is the mileage?
The Dual Mass Flywheel (DMF) is the worst thing fitted to VAG engines.
The Dual Mass Flywheel (DMF) has been talked about many times on here if you search?
I assume its a manual gearbox?
Clutch slip can be oil on the clutch centre plate or a bad pressure plate.
Normal clutch usage the clutch will wear out.
That’s the other thing about bad driving no disrespect. People hold their foot on the clutch while waiting for traffic lights to change. That puts extra load on the crankshaft thrust bearings because they want a quick get away.
While waiting for anything you don’t slip the clutch that is what the hand brake is for.
Condensation forming on the flywheel doesn’t really happen, as soon as you use the clutch to heat built up will dry the condensation in seconds.

Yes, manual gearbox, about 80K miles on odometer. The reason I think it is condensation, because I don’t have this issue during warm and dry days. I’ve been driving all summer with no clutch judder, so maybe it’s not oil that causes it.
I’m usually very gentle with the clutch, so in my case, any water on the flywheel would probably take longer to evaporate. I think during winter, first thing in the morning,
I need to rev the engine slightly and then release the clutch very slowly, this should dry any water droplets. Need to avoid any judder in the future, since it could potentially damage DMF and bearings.

Crasher will tell you more when he reads this thread.

I wonder how common it is to replace a non-faulty DMF when replacing a clutch, due to normal wear. I imagine there is no OEM SMF for my car, only aftermarket.

A DMF is fitted to almost every engine from every manufacturer now as it helps reduce Co2 production, they are now very reliable and the prices have come down by more than a half.

Well, it’s a bit like automatic vs manual gear boxes. I don’t care how many people say that VW DSGs are now very reliable, I would always go for a manual — simpler design and less things to go wrong in the long term.
I get your point about DMF being ubiquitous these days (helps to reduce vibration, torque on gearbox and CO2 emissions), but if VW could make it work with SMF on such cars, I’d much prefer that.

Soon you will have no choice as the manual will die out and if we are forced into EV’s they don’t even have gear ratios as such.

The advantage of electric cars is simplicity and robustness — no complex drive-trains or combustion engines that require all sorts of expensive systems to keep them running. The problem is many current electric cars are too expensive or too clunky, and the battery tech needs to improve substantially. I’m looking forward to buying a new electric car, but not just now, maybe in 10 years time.

Simplicity. you have no idea. sorry but no offence but they are not simple but extraordinarily complex and dangerous and the passage of time will show you this.

Extraordinary complex? In what ways? Current internal combustion engines have too many moving parts, that wear out, need constant maintenance and can fail at any time. The list is mind boggling — gearbox, DMF + clutch, gas exhaust system + DPF and SCR tech, fuel + oil + water pumps, turbos + all the components inside the engine that constantly rub against each other and need clean oil every 10K miles.
Ignoring the battery tech, which is a bit immature at the moment. In theory, electric motors are much simpler and shouldn’t need much maintenance. Simplicity equates longevity, which is good news for consumers.

OK, let’s take a 2022 e Golf and go through it from groups 1 to 9. They have an electric coolant pump for the motor, charger and power electronics control unit and another electric coolant pump for the Positive Temperature Coefficient electric water heater; this has already been revised four times since 2018. and we all know how wonderfully reliable modern VAG electric water pumps are… not. As an interesting point, if a pump acts up the temp sensor will shut you down when driving or stop the vehicle from charging whilst you are snuggled under the duvet. They still have an electric cooling fan and radiator but an additional electric radiator blind.
The coolant will still need to be changed every five years. The e motor still uses the traditional «dog bone» torque mount any Golf 5>7 owner will be familiar with AND it has to work hard due to the torque. The AC compressor is electrically driven and has been so unreliable it has been revised five times since 2015 and the A/C system is conventional other than that so all the usual issues.
The suspension and drive shafts are utterly conventional MQB Golf style with the multi-link rear end which is now causing Golf 5’s to be scrapped due to the costs of rebuilding it. The brake hydraulics are also conventional stuff familiar from the Golf 5 onwards but instead of a nice reliable vacuum operated servo there is a £1K electromechanical servo. this has also been revised five times since 2015. On top of that there is also a £1K pressure accumulator, bet they will be fun when someone hasn’t changed the brake fluid in 8 years! The brake calipers and friction materials are all conventional parts BUT EV’s have regenerative braking which means the brakes hardly ever get used and will rust solid, this is already a known issue with the Nissan leafitalone. There is a conventional cable operated gear selector and pedal box auto style, already revised twice and then we move onto the body which is just MQB tweaked to become MEB so anything that could happen to a Golf 7 or 8 will apply. Then we have the thrice revised traction motor unit which is the motor and gears in one, there are no spares available for this so almost ANY fault means £4.5K for a new unit. If the internal alternator fails, this is not replaceable. The aforementioned high voltage charger is £1.5K and the car still has a conventional drivetrain ECU.
Then there is a power electronics control unit which is £4k and all the rest of the electrics is normal such as BCM, dash etc and all being run off a separate conventional AGM 12v battery which is only charged when the vehicle is running, not whilst the main battery is on charge. As an interesting point, if you have a problem with one of the range extending LED headlights, the base model unit is £1.3K. per side. I have jumped step though, my favourite big deal breaker for any EV, the shocker if you like. the 396 volt high voltage traction battery. This has a warranty a shade under 100,000 miles and spans a maximum of eight years. a new one is currently (sorry) £19200, yes nineteen thousand two hundred pounds, plus fitting which is ****** dangerous.
To move the battery around you need an £840 transport box or no one will touch it. I agree modern engines and boxes are WAY too complicated but that has been forced on us by the minority eco warrior shouting heads making the ECU introduce all sorts of daft and conflicting technology that has required the incompatible bed fellows of low Co2 production and reduced toxic emissions to lay together, take the 1.5 FSI Golf 7 as an example of trying to run an engine as lean as possible to keep the Co2 down but also not spit out nasty toxins and particulates that are generated by the combustion process, so bad that the technology now requires a petrol engine to have a particulate filter when my 17 year old petrol Octavia doesn’t which is ULEZ compliant and has done 200K miles.
