    Just had a partial service (filters changed; oil changed, sparkplugs changed and a health check including scan with star)... All's well but the lesson I learned is to check my plugs before buying new ones.
    I guessed that after doing over 62k miles I should change the plugs.

    On removal of the NGK platinums, they needed only a wipe and they looked like they'd only been in there a week! Anyway, the new ones went in so at least I have peace of mind.

    My local Merc indie guy is Nick at Parkham Garage, Wellingborough, who is a star and any local piston heads should pay him a visit rather than take out a mortgage at Merc, Northampton. (Last time I was in there I thought I was in the 'Dorchester').

    My ML55 AMG engine is a credit to whoever built it - there are no 'signature plates' on my engine but by Christ is don't half go....!

    Whether you actually change the plugs or not, they should be removed and cleaned at the specified interval otherwise you risk them seizing in the heads.
