Pat Goss on the CDI..
I sent him an email basically asking about additives to use on occasion to keep the injectors clean, etc.. here's what I said and he said..
Hi Sam:
I certainly wouldn't lay claim to being a foremost anything but as
far as my
CDI goes yes I use an additive. The one I use is made by BG
Products 248 or
BG 44-K. Both are excellent products that help keep those expensive
injectors clean without the possibility of damage to system
components.
Hope you like your CDI as much as I do. It is the most amazing
vehicle I
have driven. I love the performance and the fuel economy isn't bad
either.
Sincerely,
Pat Goss

Hello
Hope this can make it to Pat Goss.
I read with great excitement that Pat drives a Mercedes CDI.. I
drive one too, and love it. I wonder if one of the foremost
mechanical minds in the business can help me out with a quick
question..
Do you use any (techron, etc..) additives in your CDI at all? MB
says not to, but then they only have to worry about the car for the
first 50,000 miles!
Thanks
Sam
I like the last part of his email...
Remember, your warranty lasts thru 50,000 miles, but your car may need to last well over 100,000...

If, for expample, you tried a lemon law return and the manufacturer asserted your breach of their instructions (and they linked it to the failure/problem), you'd be in a tough spot.

That all said, my thread wasn't so much about additives but about the comment that Pat love's his CDI.

I 100% endorse Khaug's comments. Mechanic's do indeed speak from experience and with the greatest of respect what experience do they have on these very modern CDI engines?
These vehicles are regularly used by our emegency services which thrash the living daylights out of the engine. The vehicles are expected (and do) last for three years after which time they are bought back by the supplying dealer. Each vehicle will do approximately 100,000 miles per year and have its oil changed at approximately every 20,000 miles in accordance with the Advanced ASSYST servicing system. These vehicles are being used because of their excellent reliability, and brilliant buy back price (300,000 miles on the speedo???) (They are mostly 320CDI Avantgardes fitted out with Police equipment)
The 320CDI is proving to be extremely reliable especially when you consider the service intervals, and NO repeat NO additives are put into the fuel (unless the dealerships decides to put a recommended product in at service).
This to me is experience! We will never drive our vehicle in the way the emergency services drive theirs and if the car is good for possibly 300,000 miles of hard earnt motoring, then I'm sure it will survive the mileage that the average owner will acheive without putting any 'additive' into the tank.
It is always worth absolutely flooring the throttle periodically just to 'clear out the old tubes' but I would avoid additives like I would avoid listening to a political speech.
Finally European 211's have the 30 year Mobilio warranty which is free and provides a free breakdown cover anywhere in Europe\Great Britain for the thirty years, so they must be pretty confident.
Have a nice day,

I love reading your responses. The fact that they can beat up their engines in that manner yet still are reliable is very reassuring to me.
Cheers!

I couldn't believe it when I first saw these vehicles being used, but like you, I looked on the positive aspects of it.
Police vehicles are usually serviced at there own workshops, but the 211's are very much the exception. They always go back to the nearest Mercedes-Benz dealership, although I don't think they get a courtesy car.
Nice speaking to you, and take care,
John
As for additives.. my mechanic (Dealer) said they will run a cleaner (BG44K) thru at the 13000 service.. so I am willing to suspect that your commercial fleet gets some kind of treatment during their 20,000 service. Diesel, at least here in the US, has a lot of particulate matter, and what your fuel filter doesn't catch will cause your injectors to clog up, and reduce (not eliminate) your fuel milage and power.
The purpose of the manual statement is so that end users don't just go grab any old additive off the self at a local car parts store and dump it in indiscriminately. Pat Goss, and my mechanic are enough proof of the need for good additives on occasion for me.
An excellent point, your diesel fuel is indeed 'different', and your dealer will no doubt be fully informed on how best to deal with this. I still believe that it might not be the wisest move to simply pour in any old 'off the shelf' product. Stick with main dealers that get regular and updated information from Mercedes-Benz will always be my choice of servicing.
The 320CDI is indeed a tried and very trusted workhorse, don't forget it has been available in Europe for over five years, some European countries even use them as taxi's!
There will no doubt be the exception and someone somewhere will no doubt know someone's uncle, whose aunt has a nephew whose father had a 320CDI that blew up after only 20,000 miles.
This is our fifth CDI powered vehicle (second 320CDI) and I can see no reason to ever go back to a petrol powered car.
If you ever get the 420CDI over there then this 4ltr diesel will blow away the E500 and laugh at petrol stations as it cruises by them. Let old dyed in the wool folks laugh, but I respectfully suggest it is the laugh of maybe a little envy?
Happy motoring,
John

It has been deemed uneconomical to adapt this vehicle for us 'civilized' folks who drive on the correct side of the Queens Highway! So no 4Matic's, and no V8 E-class
Regards,
John
