What exactly is a 'D' service?

Took my B class into a Mercedes dealership today for a quote as my dash is telling me I have 1500 miles until its due a D service - 6 years old, 35000miles.

Apparently its the same as a B service. A (+C) = minor, B (+D) = major.
I was told that an A was £225. Not much help as I asked for a D (B) service but finally found out that "thats only £299". Ok, I thought but "what is done"?

I could not get an answer from him apart from "a change of brake fluid worth £50 and an internal/external filter for air coming into the cabin (whatever that is)". I told him that I changed my brake fluid when doing the brakes 6 months ago so didnt need that doing.

So what is this D service then? Can anyone shed any light as to what will get done and are they likely to pile on charges midway through as they said they would need to check the computer with the chassis number to find out what exactly will need doing - although he wasnt prepared to do that then. What a headache, Im not prepared to hand my car over to a dealer to be at the mercy of what effectively is a blank cheque.

All these letters are in fact pretty meaningless. Certainly our local dealer just sticks to A or B plus whatever else seems to be due on a time basis - eg brake fluid, plugs etc.

The letter thing used to be an indication of how long the job takes i.e. A service is one hour, B is two hour, C is three hour so on and so forth...

The letters signify how long it will take (I think from memory D means it will take between 3 and 4 hours). The actually elements that make up that time always vary.

^ Or we he said above. Doh!

Thanks guys. I was told by the MB service dept that A, B, C, D, E, F etc referred to the order of service. So next year would be an E then a F etc.

Im mainly trying to work out what gets done in a B/D/2hour service to see whether it is in fact worth taking it to MB or if its a giant rip off. I have full MB dealer/specialist service history and would like to keep it that way for resale value but need to work out whether what they actually will do with which they dont seem to want to tell me.

Lots of Mercedes!
Nope they are talking rubbish. Most generally ignore the letters and will go A/B alternate taking into consideration the extra time related items.

I couldnt work out whether he didnt know what he was talking about or deliberately feeding me rubbish. I think he was just clueless, either way not reassuring.

What is generally included in a B service over an A service? I have a feeling spark plugs will be included which would make it more than the £75 he quoted which makes me nervous of receiving a bill higher than quoted.

Strangely, mine needed an F last year and now requires a G this year.

Why is that strange? That would make sense.

Lots on the web - as a for example:

What is service A, A1, A2, B, B1, B2, C, D, E, E1, E2, E3, F, G, H, or + service for Mercedes Benz and how do i determine what it is?

The services due are determined by the car based on mileage and time. A-H is a time indicator for how long the service on your car will take to perform (A=1 hour , B=2 hours, max H=8 hours). If you have a + after the service that means you are due for a brake inspection.

The services due can be any combination of 20 possible services. To view the service item(s) that are due, you can call up the service menu in the multifunction display. It will tell you the service code due, but to determine what service the code correlates to, the Mercedes Benz service information program (WIS) will have to be called up. The services do vary from vehicle year and model so a service number 5 on one car can be completely different on another car.

Common service items for late model cars using ASSYST PLUS:

Oil and filter change (12k, 13k, or once a year. Europa Auto recommends changing your oil every 7,500 miles)
Cabin filter (26k or 2 years)
Air filter (52k or 4 years. We recommend changing the air filter more often. This is included in our B service.)
Car inspection (Once per year)
Brake flush (Once every 2 years)
Spark plugs (Depends on model usually every 78k, 100k, or every 5 years)
Fuel filter (65K or 5 years)(Diesel every 26k)
Charcoal filter (60K or 5 years)
Transmission flush (Once at 39k 2006 and later model year)
A1 service (1 year or 13k miles): A service in addition wiper blades.
A2 service (3 years or 39k miles: A service in addition wiper blades and transmission flush service. 4-matic also has transfer case flush.
B1 service (2 years or 26k miles): B service (dealer does not change air filter) in addition to brake flush.
B2 service (4 years or 52k miles): B service (dealer does change air filter) in addition to brake flush.
E1 service (E class at 50k miles): B service in addition to brake flush. Diesel engine replace fuel filter.
E2 service (E class at 60k miles): A service in addition to fuel filter (Gasoline), and spark plugs.
E3 service (E class at 70k miles): B service in addition to brake flush. Diesel engine replace fuel filter.

Post #6 was dismissing.

I understood each letter was a time thing based on the number of things being required.

I don't know for definite though.

If you want to know what work is scheduled for your car, then fill in the ESS: Mercedes-Benz ESS

Even this is only predicting. Just read the service book! Work it out
It's hardly rocket science fella.
Very few reset assyst plus correctly, so what your cluster is telling you is probably bullsh..t anyway. Read the service book and it will explain all!!!!

Thanks,
Ive just run my vehicle through and it has come back with what it looks like should be done based on age and milage. Basically this "major" service includes a replacement oil and filter change, brake fluid change (done 6 months ago) and thats about it. The key fob battery is replaced but apart from that they just do a lot of 'checks' like wipers, making sure the headlights go on and that the brakes work. :dk:

No wonder they were so evasive. I mean how do you tell a customer that you are charging them £300 for an oil change and the assurance that the car they have just driven in to be serviced can be driven in.:eek:

Thanks for that. There is a lot of info on the internet. Take the above post about the ESS. It gives contrasting info to this and this is just on one thread. Knowing what it should be is extremely difficult.

Im just wanting Mercedes to tell me what they will do and how much it will cost so that I dont get a nasty surprise at the end of the day (my trust in them is waning fast). It really isnt unreasonable yet its something they dont seem to be able to do. Whether its easy to find out or not is not really my problem. Leaving a customer scratching his head with unanswered questions as to what he is paying £300+ for is not really ok.

Hmmmmmm.

Ever tried to figure the spark plug change schedule for a R170 from its service book?

I'm not sure its science as a set of mystic clues and spells.

And I'm fairly sure Assyst+ is based on upgrading from that to astrology.

Behind the scenes the dealers probably get the equivalent of Tarot cards. They take a sample of your hair and mix it with a sample of the engine oil and then burn it while drawing the cards to decide what to do to the car and how much to charge.

Can dealers put on additional charges as they see fit? I have read a few reports where they have 'checked' parts as per the service schedule only to find that parts need replacing and added £200-£300 more on top of the standard service cost.
