My ed30 was done at 14k and then 28k on LL. The R32 I bought has the first stamp at 16K (whoops forgot to check that), but ticks over sweetly enough so I am not concerned.
LL seems to get a bad rep, but if you are doing 15k+ a year with longer journeys etc then I dont see a problem. If its purely short town driving then go TD.
iirc they do know if it has been driven for too long with the service light on. More than 2k with the service light on then bang goes the warranty I think. Dealer should be able to check that.
