Another stupid question: Is your VRS a diesel? You will not get a regen if it is petrol. There are 2 kinds of regen: active and passive. Passive happens automatically when a sufficiently high temperature is reached in the DPF. As far as I know there is nothing to indicate that this is happening. Active regens are needed from time to time, as the passive regens are not normally enough to take care of all the soot that builds up. When an active regen is in progress the idling speed is a bit faster than normal: 1200 rpm rather than about 900-1000. You may notice the faster idling speed if you have a DSG and are coasting in eco mode. If you stop before the active regen has finished there will be the noise of a fan running and a burning smell. The purpose of the regen is to burn off soot which builds up relatively quickly in the DPF. Unfortunately this produces ash which is not eliminated by the regen process. It is the build up of this ash in the DPF which eventually requires replacement of the DPF.

Could it be the same issue as this?

Clearly the position P warning only applies to cars with DSG. Several models have been reported on here to have this error apart from Fabias, but looking at the postings on here I get the impression that it is mainly Fabias that have related issues with door locking. In my Octavia I occasionally have the error message flash up while I am driving, but that is as far as it goes.

According to tech info from VW, which I have quoted on earlier threads but can't find at the moment, the active regens are first triggered when the soot content of the DPF reaches a certain level, 45% I think. Regen attempts will then continue when conditions are right until the process completes successfully, or the warning light comes on indicating that intervention from the driver is needed. My driving pattern is not what might be considered ideal for a diesel engine, but in over 4 years of ownership I have never seen a DPF warning. Occasionally the fan running with a burning smell indicating interrupted regen has occurred after switching off, and occasionally I have noticed a higher idling speed indicating regen in progress, mostly when DSG is coasting in eco mode. I got the Carista and VAG DPF app to reassure myself that all was well, and have now come to the conclusion that the car will take care of the regens OK and I don't need to worry about it.

Yes, as Alex says this applies (mostly) to diesel cars only and the purpose of the regen is to burn away excess soot in the DPF (Diesel Particulate Filter). Some newer petrol cars have a GPF (Gasoline Particulate Filter), but GPF regen issues don't seem to be common at present. You should be able to do this with Carista using the VAG DPF app on Android. Many but not all VW group diesel engines are supported in the app, and there is a free version that you can try to see if it works for you before shelling out about £3 on the paid version that gives more detail. It works on my 2015 2.0 TDI with bluetooth Carista and a Lenovo tablet.

I wasn't saying my car was miss-sold, I was just speaking generally. I was fortunate enough to get an early Euro 6, so I am not personally affected. I feel very relieved that I didn't buy one of the affected cars, as I so easily could have done if I had purchased a bit earlier, although you seem to be saying that I wouldn't have been greatly disadvantaged if I had. For emissions and economy the Scout DSG is actually pretty good for a car with 4x4 ability, DSG and the same engine power as the VRS diesel, and I don't regret my choice one bit. Maybe but I wouldn't count on it. Cheers!

It is not about mental anguish, it is about the cars being miss-sold. I can see where you are coming from, but if you ever get involved in litigation it won't be your "book" that decides the outcome in court.

I stand corrected. Not sure how I got the idea they were cheating with CO2.

No, I was just referring to CO. I understand NOx is a more recent issue. Maybe they just couldn't find a way to do it properly within the time limits. If that was the case they might have seen cheating as a better option than ceasing to sell the cars. It seems to me that they must have continued to work on the problem as they would have needed to do, and they had apparently found it possible to meet the stricter Euro 6 requirements by the time that those came into force. As it turned out they were able to cover up the cheating until the Euro 6 cars went on sale, so in that sense the tactic worked for them. It seems to me that cheating would have been a last resort for them rather than a cost saver given the risk of the truth coming out. Not sure about that. i believe compensation can be applied in relation to any kind of loss or damage that can be proved in court, not just financial.

If you don't get what you paid for, that amounts to a financial loss. Also there will be a financial loss due to consumption of extra fuel.

There will be some people who were influenced by environmental considerations in their choice of cars and didn't get what they thought they were getting.

I would expect the stop - start system to have enough intelligence in its design not to damage the turbo or other car parts through its normal operation.

Sorry I'm a bit late to this, but just saying that I have been using Mozilla Thunderbird for several years. Started it on Windows XP and moved it to W10 a couple of years ago. Works fine with multiple email accounts and thousands of messages, so I concur with you guys.
