Does the mk6 gti come with a default setting for LL service then ?,
ALL VAG engines are factory filled with LL oil, irrespective of weather they go to a country which can use LL or not.
But there is no such thing as a 'default' setting. The service schedule is ONLY set by the suppling stealer as part of the PDI, and unfortunately, unless you specifically tell them you want the T&D, they automatically set it for LL.
On my service history in the owners manual they have ticked the t and d service intervals section
Which was done by a pen pusher at the stealer.
but on the trip computer it says LL.
Clarify. What exactly does it say?
Anyway, that will have been set by the grease monkey.
I have purchased the fixed price (£250) 3 year service plan 12 months,24,36 so i presume they will reset it after the first service but does it matter ? isn`t it just a way of the car telling you the car is due a service ? (as long as you get it serviced at the correct intervals)
But you don't expect to pay 20-odd grand for a brand new car, only to find they failed to correctly set it up!

You pay a specific 'delivery charge', and part of that includes the dealer correctly preping and PDI-ing the car - and they failed to do it correctly.
If it is wrong, demand they set it correctly!
