Just Bought E320 CDI Bluetec
(1) Thank U Carsy .... good news that so many more oils meet the M-B spec 229.51. I'll check it out. I saw a FLEECE filter for M-B (Fram brand ) listed on website site oil seller, for 11. I have to go to M-B dealer to buy new M-B floor mats, tomorrow, so I'll ask 'em what they get for Mobil 1 ESP 5W-40, and the oil burner fleece oil filter.
I don't think the Diesel filter is fleece. Check it at the dealer. The one on my 06 E320 CDI is not.


Aside from the transmission I love every thing about the car, with the possible exception of the comand/navigation system.
Like I said hope you have better luck, there seem to be lots of happy owners out there and I would be one of them if it wasn't for the transmission issue.

I wondered ,how many miles has the car done & whether the trans has had the oil flushed ?
From memory the 7 speed is supposed to be serviced at 39,000 km .
MB say the 5 speed is OK for life but all MB mechanics say to change the oil at 39,000 miles ( 60,000 km) also.


Just today I got perhaps a taste of what's coming this winter. Twice I unintentionally peeled out turning onto a busy road to merge with rush hour traffic. Had this been a snowy road I would have been dead in the water even with snow tires. Having a high torque rear wheel drive car with no "winter mode" is insanity. The trick to driving in the snow is smoothness, no big sudden inputs.

Do you have a good independent European auto GB specialist nearby ?
If you look on the W 203 forum search engine in MB World you will see some info on changing valve bodys ect.
Good luck with it & let us know how you go.


I trust for the price per quart I was charged he used the right fluid, but I can't put my hands on the service receipt at this time. This guy is very particular about fluids, he always uses some German synthetic engine oil instead of Mobil-1. In talking to him I came away with the impression that he was not entirely comfortable with everything related to changing the valve body. specifically he various SW updates. That's why I am concerned about being charged again for the fluids if I have to go to the stealership.
Diesel Benzes are rare birds around these parts so there's not a deep repository of knowledge regarding the vagueries of Bluetec automatic transmissions. For example it took three visits to the dealer to find out about the "C/S" button disablement.
Obviously you need some top technical advive regarding symptoms.
A few phone calls to capital city dealerships may be worthwhile.

Good luck. Keep with it. You will win in the end.

I have talked to other dealerships and I get "we can't give an answer without looking at the car first" type answer. Meaning take a day off from work and pay us $150 to get an answer.
Thanks for the link of the thread. I've read many threads on this forum and others. There are definitely issues with the 7G transmission regarding the shifting issues, with no clear single issue resolving them.
Off topic, what is behind your C in your avatar? It looks like a trailer. In this country, USA, only the MB light trucks, ML, GL, R, and G our allowed to tow anything. Some sort of liability issue because the same is true for almost all manufactures.

Yes, its a trailer of about 1 ton of cow manurefor the vegies.I think the unbraked legal load for the car is about 700kg . I am amazed at how well the car handles this load. Very stable & with 400 Nm of torque you hardly know it's there.
Good luck with the gear box. I remember reading that the 7 speed has a memory of the way it is driven . This can be reset.
There are some very good technical minds on the 203 forum which may be able to diagnose your problem. I suggest leaving a post there explaining your problem.

Hello Carsy and Gang.
Fatherland ... I bought my '07 E320 Bluetec with 54K miles about 3 weeks ago. The MB dealer I use ( Shrewsbury, MA ... 35 miles west of Boston ) did some earlier warranty work on my car.. The trans was ONLY TIME NEEDED serviced at 43K miles ( 40K is the callout ) then U leave it alone for life of car. So says the "official" maintenance schedule
I bought car from a local "legal" VW dealer, and it still has 30 + days left on limited ( 60 day ) warranty. In both C and S ( comfort and sport ) settings, the 7G-Tronic starts in 1st gear, and has same shift pattern. So, I'd better get my sorry *** to MB dealer to see if I have a "warranty claim" with VW dealer. THAT should be interesting. VW dealer "tried" but put wrong diesel oil in car when they serviced it for resale. I had MB dealer use the right stuff ... in BULK, they charged less than internet sellers of Mobil 1 EPS M5W-40. So I really don't want VW guys playing with 7G trans ..
This MB dealer seems familiar with the car and tech stuff....FOR YOU, I will ask them about the abrupt shifting issue in first 3 gears. I will send U a private e-mail via MBWorld, and will also post it on this thread. Give me a week.
Stay Well To All >> NoFoolyn
