It's certainly not obvious to me. I still don't get your point "the OP is talking PHEV". A PHEV still has an internal combustion engine capable of producing emissions and liable (in certain circumstances) for an undue idling offence. Perhaps you're simply trying to be argumentative - are You ???

"but because the OP is talking PHEV" Explain please.

I was trying to keep the post brief but to the point and not do a full discourse on all the exclusions, ifs and buts. You're the only one to mention Private Ground !!

Moreover, in the UK, idling is an offence under The Road Traffic Act 1988 Section 42. And yes, you guessed correctly it's to do with air pollution.

I have a 20l Diesel Kodiaq Sportline 190 bhp, new in March 2025. In particularly cold weather in Glasgow (between 2C and -6C) I've noticed that on occasion the lock/unlock feature doesn't work but a press of the button on the front door handles works perfectly. My previous car, a 2022 2.0l Diesel Kodiaq L&K, behaved exactly the same in the same atmospheric conditions. Has anyone else experienced the same? I can't really say it's a problem since it happens so infrequently, it's merely an irritation.

What ???

I understand that KESSY places a strain on the keyfob battery so that would suggest that the battery will need to be replaced more often. Given the ease with which the battery can be replaced, and the low cost of the battery itself, this is not a deal breaker. Deactivating the KESSY system is akin to throwing the baby out with the bathwater.

I can't help you any further.

A quick search on Google suggests that this is a known issue, essentially due to the inherent imbalance of running a 4 cylinder engine on only 2 cylinders. Worn engine and/or transmission mounts are one probable cause. Another probable cause is that when running in 2 cylinder mode the exhaust frequency changes causing the exhaust system to vibrate against heat shields. Thus exhaust hangers, heat shields and connections should be checked for integrity. On some VAG cars a loose wastegate rod can cause rattling which can feel like vibration and in cars with direct injection (like the VW 1.5 TSI) carbon buildup on the intake valves can cause rough operation when in 2 cylinder mode. Bearing in mind the high mileage on the subject car in this post, carbon buildup seems a quite likely cause of the problem. The ACT system relies on oil pressure to activate the solenoids that disable the cylinders. If oil pressure is low, or if the oil control valve is sticking, the cylinders may not deactivate/reactivate smoothly. Depending on the car model driving in sport mode disables the ACT but obviously this is a workaround rather than a solution. Given the diverse nature of the possible causes it is not at all surprising that 'qualified' mechanics have thus far been unable to determine the exact cause. Good luck Brian15 - I think you'll need it !!

From your pevious replies I would hesitate to call you naive. I don't believe for a second this is a feature (it would be the most pointless ever). This is clearly a defect. Whether it affects only a limited number of vehicles is not to the pont, it is still a defect which Skoda has been advised of. In true 21st century corporate behaviour it will not publicly admit to the defect but will fob cutomers off with any old excuse under the sun until the real technicians do some proper testing and remedy the fault, or until a significant number of car owners begin to reject their cars under Consumer Protection legislation and tell the general public through social media of the reasons why.

Does the car have a full service history? I agree with Warrior193. Something other than ACT is at the root of the problem.

With the greatest of respect I think you place too much faith in Skoda Dealerships and in users manuals (which in many respects are no real use). I'm convinced PHEV and pure electric Skodas have been rushed to market, without adequate systems testing, just to show the world that Skoda are ahead of the Zero emissions mandate.

It's because of the battery which sits where the third of seats would be.

In my Kodiaq Sportline if I set Auto Hold to on it remains that way until I stop driving and turn the engine off. On restarting Auto Hold is off. IMHO that is the way it was designed to work. I suggest you get the car to the supplying dealership and get it checked.

In the UK ACC is not a mandatory safety device.

I'm not criticising, it is your choice of course, but why rely on ACC? You are in control of the car and, by law, you alone are responsible for the manner in which it is driven. That said, why do you abdicate that control to an electronic system which may or may not be infallible ?

This is exactly why I never use ACC. Some users have also posted that AEB is also too sensitive and has caused some rear end collisions. My 2.0 litre diesel Kodiaq Sportline has occasionally flashed up the advance collision warning sign on the dash but thankfully has never applied emergency braking. I may just be lucky in this regard !

Hardly the point though !!

I've been reading these comments on PHEV and pure electric models and it seems to me that Skoda perhaps rushed these to market without fully testing the currency of the software and its performance. These sorts of problems are absent in ICE cars.

I have the Kodiaq Sportline and it has the mandated (under EU regulations) speed limiter. This is enabled every time the car is started. Should you exceed the permitted speed limit on any piece of road, the limiter will emit an audible alarm but there is no automatic reduction of speed to the specified limit. It is frankly an irritation as is the lane keeping feature. I regularly turn both off before I move the car. My car also has ACC but I never use it. I don't think is has any effect on the speed limiter.

More reliable? It isn't just the interior trim that's compromised. Engine, electronics, gearbox, suspension are all built to a price. Good luck if you choose one !!

Take it back to the dealer for a warranty replacement.

Have a seat in any model of Dacia and you'll quickly realise why they are so cheap. They are designed to a minimalist specification and it won't take you long to walk away.

My 2025 Kodiaq 2.0 litre Diesel Sportline is not even 1 year old. A couple of weeks ago I got a message on the dash advising a drop in pressure on the nearside rear tyre. i pulled into a service station to re-inflate the tyre, and as luck wouldn't have it, I saw immediately a machine screw or nail protruding from the tyre tread. This was at the beginning of the holiday season and I decided not to go far. I checked over the next few days and surprisingly when I checked the pressures it told me all were within specified range. Clearly the screw/nail was providing a seal against further pressure loss. Then my dilemma. It's a heavy but powerful car. I tend to drive 'spiritedly' and regulary travel to France and Germany on holiday trips. Would I be completely comfortable at Autobahn speeds with a repaired rear tyre? Wiser counsel prevailed and I got in touch with Black Circles who offered the exact same brand and size of tyre to be fitted at a local garage near me. The job was completed this morning and I have nothing but praise for Black Circles and also the local tyre fitting place. Perfect service in this day and age !! I can't recommend them highly enough.

I routinely turn lane assist off every time I start the car. The way in which the steering is jerked when you stray out of lane is quite disturbing.
