Following a number of requests for information on the servicing schedule for the above car I will attempt to put forward a list of items covered by each service. Please note that this applies to the petrol model 'A' Class.
To undertake a service on any car, good sound knowledge of cars and mechanical skills are required, it will also be found that to do the job correctly a number of tools are required, some being beyond the toolbox of the average DIY mechanic, we therefore have to bear in mind that some tasks on modern cars will be beyond our capability due availability of tools or lack of expertise; at which point we must and should seek
professional help. In the main the A & B service will be within the scope of the average DIY and the tools required will be in the main standard to modern cars, however some special tools such as star drive sockets and other tools will be required to enable you to do the job efficiently and easily. Using the correct tools also helps reduce damage to component parts which can be a costly to replace.
The Service Assyst facility on this car will demand a service every 12 months, any remaining time in miles left on the Assyst indicator which forms part of the dash display will be wiped and Minus sign along with a number of days, as well as an audible warning, will display and be heard. This warning and display will continue to alert you every time you start the car, until the car is serviced or the Assyst is re-set. The days will accrue two days for every one that the car goes without service over the 365day allocation (twelve month service period) Ie 7 days overdue -14 will display along with the audible warning which will sound for a few seconds and then stop, after which the dash display will also return to normal working.
During the period of display there will be either a one spanner or two spanner icons showing centre to the instrument cluster. This indicates the service required 'A' or 'B' that is due, 'A' being a minor service, single spanner, 'B' being a large service, double spanner.
This list will include items which I carry out that may be in addition to the Mercedes- Benz list, but in my opinion should be included in any DIY service schedule, I will mark them with a red asterisk
The information supplied on this page is based on parts supplied for Mercedes-Benz services both '

Remove wheels and Inspect front brake pads for wear, inspect and service callipers as necessary
*Note I was informed when I enquired that MB do not remove the wheels to inspect brakes but do visually inspect via the hole in the backs of the drums, and visually inspect the front pads I find this totally unacceptable as the rear drums need to be cleaned to get the best from them and leaks on calliper seals and rear wheel cylinders cannot be detected with the wheels on.

* While each wheel is removed inspect the coil spring for rusting and inspect the shock absorber in each case checking for leaks from the cylinder.

Other items charged for on my 'B' Service included:-* Fuel cleaner * Car care kit * 'Superlube'
I am not aware if these items are charged for on every 'B' Service as standard Of the three the only one that may be required is the fuel cleaner, it is reference on my bill was only ZFSC priced £10.95 so what ever make it is it should be good! 'Superlube' was aerosol spray lubrication for door locks, hinges etc priced @ £3.85 and the Car care kit @.89pence, paper square to protect the carpet and protection for the drivers seat? Nothing that can't be provided by the car enthusiast.
Since the formation of this page I have been in contact with Mercedes-Benz customer services UK . They have confirmed that Fuel System Cleaner does not fall within their definition of fuel additives. As outlined and prohibited on page 25 of your Service Booklet. ref part Number 168 584 02 93. The ref to quote should you ever suffer a problem as a result of using such cleaners is:- Lisette/Case number 1-498321446/29.03/06. Rowe

Copies Of service /Check sheets
I have added the check sheet used by the service department carrying out a 'B' service on my own car, which indicates what has been done, and what extra's are required at a given mileage/age. If you have not seen these sheets before then I suggest you ask for a copy following your next service, it is no good paying for a professional service if you do not know what has been carried out.
Re setting the service ASSYST
If on the other hand you have done your own service then you will need to re-set the service ASSYST, this will automatically display the miles to the next service as well as the service A or B, and this is done with the blessing of Mercedes-Benz, well they do give the procedure in the handbook , it is also on my technical information page.
Having said that, it is easier said than done last year following my B service I re-set the ASSYST no problem, this year following a very thorough 'A' service, I was unable to reset even after several tries I failed, So I sought the professional services of John Haynes Worthing's Independent Mercedes-Garage, and where you can see some real Classic Mercedes of the past. On one of my previous visits I saw two fantastic classic limo's being picked up on transporters following their service for their trip back to London. They had come to John's Garage and yet must have passed many garages dealing with Mercedes on the way. That has got to say a lot for the service and knowledge that John & his team of mechanics and staff including parts department who are always helpful and friendly, something you will defiantly not find in you average Mercedes franchise Branch, no matter how large or sophisticated albeit I have no problem with the staff on the service team at the Chichester branch who are also helpful, although I feel their service is prohibited by the high service costs along with the extra charged for.
www.mercedesj-a-haynes.com when I explained my problem to John he immediately dealt with it and one of his mechanics had the ASSYST re-set in seconds. www.mercedesj-a-haynes of my arrival and John didn't charge me either. Thank you John your help was very much appreciated.
