Treg went in for it's 1st service today. I also wanted them to look at the sinking front seats - sorted, overtly firm side bolsters on the seat base - nothing wrong, broken trim B pillar - replaced. Burnt rubber smell --- A bit of oil leak from the engine, and will need to have the engine removed to fixThe dealers are currently awaiting vw technical services to approve the work. I did notice this smell a few months after I bought it, and even checked the tyres. There is no oil drops either on the drive or garage floor. Good thing the treg's still under warranty.
