minor service is oil and filter with a full health check.
Full service is oil air and plugs with a full health check or am I wrong?.
Yep, minor is oil and filter change, plus pollen filter if required.
Major is the above plus spark plugs and air filter if required. Both have safety checks though I think the major is more thorough where they remove wheels to check brakes etc and adjust tension of drive belt.
I was about to book a major service too so that's £30 wasted!
Pollen filter would be at extra cost?.
Drive belts are tensioner driven so I think that doesn't need adjusting.
Brakes checks are wheels off front and rear inner and outer discs check, although this is also done on a minor one less the wheels off as that's what I do in profession.
All cars are health - safety checked because if you have an accident and it's proven something like the brakes were at fault then you can sue the company for negligence.
