Long life servicing

[goodwill]

When I got recovered by the AA the other week due to CV joint failure I was have a chat with the AA man who used to work for VW as a techie and owned a Touran 2.0tdi 140. Anyway I mentioned that I thought it was a con that VW engines can go 20k for an oil service where as Seat only 10k. The guy explained that Seat cars can be converted to long life servicing (20k) by re programming the oil sensor in the sump and replacing the oil with long life oil. He mentioned that this could only be done on cars with a certain set of letters on the cars data sticker which were CQG. Intrested to know if anyone else has heard about this or its somthing to look in to.

Another one for Klawit I reckon.

I top mine up with the extended service interval oil since it's suppose to be a better quality... I started off with it so I continue. My understanding is that some garages only stock the extended interval oil change for reasons of economy if they service both types of cars. Thus I'm not sure where the sensor thing comes into it.... I'll bow to better knowledge.

If the sump has the oil sensor fitted then it can be converted (with VagCom) to run on the extended sevice interval, and uses the sensor to monitor the oil quality to recommend when to sevice.

If the sensor isn't fitted, then there's no way the computer can manage the long sevice interval as it can't monitor the oil.

Well, as a matter of fact, the current generation of PD TDIs (starting late MY07) do have to have the long life spec. oil (50700), as they need this in combination with the mandatory DPF (particle filter) to reduce output of ashes.

Still, nothing to do with oil change interval ... which is regardless of the potentially more suitable oil every 15000km / 10000mls

And as long as the car is under warranty, I'd rather not try to interfere with reprogramming any vital parts of the engine ... and haven't heard about anyone in our board trying to do so.

Tell, sorry, but the presumed good deed for your engine (i.e. most expensive oil) was more or less an aid for the petrochemical industry ...
as SEAT's 2.0 TDI engine itself is just not set up to benefit from the long life oil ...
but on the other hand, it sure enough wouldn't have done any harm to it.

greets ... Klaus

That's what the nice VW German guy said who sold me the oil on holiday when it was getting low on the dip stick, so I've kept it on the good stuff for filling up there after. I did read that garages tend to keep the high quality oil if they service both types of car.

No I wouldn't mess with the service interval myself.

VW now specify only VW 504. 507. oil at 5w 30 weight for pd TDI engines. Any TDI serviced at VW will get this treatment unless you feel like arguing with the Service Manager and having him get the 5w 40 oil in specifically for you. Or perhaps supplying your own oil would gain the same end result. See, they don't hold the 505.01 oil any more as far as I know.
