You appear very passionate annoyed by vw's apparent oil cock-up. Would you care to ring a vw dealer yourself and "discuss" this issue with them as you'll be able to fight ur corner very well.
Please report back your findings as to whether you think the main dealer will just change my engine oil foc on the say so of one person's comments on an Internet forum (rightly or wrongly).
Cheers
Huh - yes, I AM passionate about oil - and most who know me on this forum would tend to agree that I know my stuff when discussing oils.
Dealers - as much as I don't care for my own local stealers, the DO know about the using only LL3 oils - they only use Castrol SLX Professional Powerflow LongLife 3 in their workshop (except for those to oil burners mentioned earlier) - so why the need for me to phone my dealer asking them to do something they already do?
And rather than dissing me as 'one person on the internet' - perhaps you might like to do 3 things? Firstly, use the search function - there are loads on this forum who understand that only LL3 spec oils should be used, even when on T&D. Second, READ your own car handbook - at the rear of the folder, you'll find a thin book - '3.3, Technical Data, Golf GTI'. Now please tell me where it states anything about viscosity grades? It doesn't - it just states VW oil standards (none of which include semi-synthetic or 10w40). Third - go to your stealer and look at ETKA - it too clearly states the VW oil specifications, and also lists the viscosities of said VW oil specs (again, no 10w40). Then you will perhaps agree that everything I've stated about oils is actually 100% correct.
Finally - if you really CBA doing that - then log onto
https://erWin-Volkswagen.com, create yourself a free account, and then input your VIN - and Volkswagen Germany will tell you exactly what spec oil is to be used.
Then fone up VW UK customer service, armed with all the evidence, and ask that they intervene and arrange that the correct oil is used - as per the manufacturer, in your car.
