Most expensive (an MBUK owned MB main dealer): £980
B-Service: £495
Fuel & air filters: £310
Brake fluid: £175
Although the service is by no means cheap , the price for fuel and air filters is OUTRAGEOUS , and why I do my own servicing .
I just bought an air filter for my S Class : £28 , and a couple of minutes of my time to fit it .
Fuel filters , generally about £10 for most models , slightly longer to fit : you have to depressurise the fuel system by pulling the fuel pump relay then cranking the engine , afterwards there are two pipe unions to be undone , which may or may not be rusted up , depending on the age of the vehicle - usually the job can be done in 10 or 15 minutes .
So , for £40 worth of parts ( say £50 just to be charitable ) , they are charging £260 labour for what should be no more than 1/2 hour's work !!!!!!!!
A large bottle of brake fluid (more than enough to do a full change , including bleeding ) is about £20 from Halfords - an 'easy-bleed' kit will cost a few pounds , but you only have to buy it once , then you only have to worry about siezed bleed nipples - I'd expect to spend about an hour changing my fluid and doing a full bleed-through . The £175 quoted for that job is perhaps not too unreasonable .
Since a basic service is in most cases not much more than an oil change , plus the 'free' software updates for newish vehicles ( but if the car is running fine before them , no reason why it should not continue to do so ) - again , I just did the S Class , which takes 8 litres of oil : 2x 4 litre bottles of Castrol GTX 'high milage' @ £20/bottle , 1 genuine MB oil filter @ about a fiver and , maybe 20 minutes of my time , keeps the engine running sweetly for another 6000 miles .
Obviously , there is much more than just changing oils and filters to maintaining a car correctly ( although if you at least do that diligently you will avoid a lot of pitfalls ) but , if you have a 'hands on' approach to looking after your car , you will not only save a lot of money but will tend to know when things need done and have more confidence in the car . I tend to spend a day or so , once every six months or so , just doing routine maintenance on mine . Larger jobs , like the recent brake rebuild I did , and the impending rear suspension rebuild are over and above - but , likewise , I will know the car is right afterwards and that the job has been done right !
A fancy waiting room and blue and white signs above the door are no guarantee of anything , other than high prices !
