Well that sounds 100% conclusive. That also answers my other question. It’s only the 1 litre tsi which has 3 cylinders, the others have 4. Obviously I’ve been looking at too many websites with misleading info. Many thanks xman for the research and manual. Brilliant!

Timing belt in oil systems, also known as wet belt systems, have been around for over 15 years. Vehicle manufacturers such as Ford, PSA, and Volkswagen use them. Wet belts are fully encased within the engine, whereas ‘dry’ systems are positioned outside of the engine crankcase. Wet belt systems were introduced to reduce the weight of components, reduce the engine size, maximise efficiency and meet emissions targets. How can a wet belt system be damaged? Oil impurities such as soot and other oil oxidation breakdown debris can get between the belt teeth and pulleys, weakening the belt. Wear on the outer belt coating exposes the underlying materials directly to the oil, which may contain unburnt or partially combusted fuel that attacks exposed belt materials. The teeth can become detached, creating a smooth section on the belt. This causes the pulley to slip and changes the engine timing. The side wall of the belt being exposed to oil and oil debris can cause delamination of the belt layers. Any failure from the belt that creates belt wear debris can cause problems elsewhere in the engine, due to blocked oil pathways, particularly in the oil pick up strainer. This would trigger a low oil pressure warning.

When I say ‘wet cambelt’ it’s because it runs in oil and it’s located in the engine casing compared to a conventional dry belt which is outside the main casing. There have been reports of the former shedding particles inside the engine and blocking the oil ports.

Hi, Having sold my Yeti I am looking to replace it and like the look of the Karoque Here is where it gets complicated for me. What is then difference between the 1litre TSI and 1.5 TSI engine. Apart from the obvious. I know the 1 litre has a 3 cylinder turbocharged unit with a wet cambelt. Does the 1.5 have the same system or is it a 4 cylinder with conventional cambelt? Thanks for reading.

Personally I don’t see the point in registering with these lawyers. Any judgement made against VAG is bound to open the doors to compensation for all affected parties, whether or not they are signed up. Just look at the banks ppp compensation scheme which started as a private. class action. Why give away 30% to the lawyers.

I have just driven 300 km to Bordeaux & back on the autoroute with first of all the dpf warning light on then all three and limp mode. So it can’t be short journeys. The comment about the EGR cooler valve iis interesting. Skoda Perigeuex have at last (after 15 months with numerous regenerations, 2 temperature contrôle sensors and telling me I was doing too many short journeys) agreed to have the car in for 3 days to do some extensive tests as they have finally admitted that there may be a post fix issue. So here’s hoping!

Great to hear that dealers in the UK have a complaints procédure in hand. Nothing like that here in France. I have registered my complaint direct to the head office of VAG group in France.

In my case, the handbook says in order to clear the yellow Dpf warning light, you have to drive at 40 mph per in 4th gear for at least 15 minutes continuous. . Then it’s suppose to clear it, but it doesn’t. I have now found out on the last two occasions that it has to be driven down a motorway at max speed for at least 30 minutes where the oil temperature reches 95º this is happening every 3 weeks on an average monthly mileage of 800 in a mix of country lanes and B roads with no congestion.

Correct Ryeman. The whole is a bloody scandal. Here in France the dealers are trained to say its the customers driving that causes the problem. You are treated like an idiot and just have to put up with it. I have written to Skoda with a formal complaint under their trust building measure. Although not sure I will get anywhere with it.

I have been plagued with exactly the same problem since the 'fix' in November 2016. 3 regenerations, new temp sensor. The local VW dealer doesn't want to know and says its my driving causing the problem. I live in rural France with little traffic or congestion. Now I am resigned to it. Every 3/4 weeks the light comes on and I have to do a half hour motorway dash at maximum speed which seems to clear it.

Ok I accept that but the last time the warning lights came on was well into a 150 km journey!

Exactly. The last time my dpf warning light came on was on a drive from Bordeaux to Paris. After another 30 Km the glow plug and engine warning light came on. Took it into Skoda Dealer.. They said there was no soot in the dpf, so recommended changing the temp sensor. They changed the sensor, then the next day the dpf light came on and after a week the other two came on. Took it back to Skoda, who then said it needed a regen and and some further calibration to the sensor and engine. Now waiting with fingers crossed. This whole saga is becoming a nightmare!

Brilliant.Many thanks Lofty 79.

That’s interesting Lofty 79. How do you do the roll back,
