Phoned a couple up and they recommend I have the 2nd year / 20K interval service. Which in the manual on top of oil change etc is they checking;
Battery
Tyres, tread and pressures
Brakes
Now those were all checked when it went in for warranty work 2 weeks ago, even got a printed "health check" sheet to say so.
So Just worth having the oil / filter service with added bits.
Cheapest so far for 2 year / 20K (using LL Oil) with brake fluid and pollen filter change is £187, the rest quote £210 - £230
