Drove a 07 E320 CDI today

Went to look at a local CDI that was for sale with the V6 and right before they introduced that stupid ad-blue trash. Hopped into it and turned the key into the accessory-on position and the steering wheel tilts down. Fancy! Had gobs of torque and lots of passing power. However, I felt the 7-speed 722.9 transmission is a bit harsher than its predecessor 5-speed 722.6. I felt each gear change a lot more in the pedal than the 722.6. Which IMO the 722.6 is smoother. It was very fast for a diesel and with the CDI injection, it was mistakable as a gas motor to the untrained ear.

However, I took the engine car off to look around and it was a total rats nest under there with the V6 and electronics. If I was to buy a CDI (which is in my future), I'd go with the straight six and deal with the injector issues they're known for. Easier to work on and a more balanced motor. I really liked the responsiveness of the steering, the box was very quick compared to the w210.

In all honesty, after driving my first w211 I would have to say it is not a whole lot different than a w210 in ride quality or comfort. It has a updated interior and a command system and a few extra gadgets, but not worth shelling out any extra money when you can buy a really clean w210 turbo diesel for $4500. I will buy one in the future just to have one, but other than that my w210s suits me real well.

Should have bought it, as it was the only one in existence.

BlueTec. Sorry for the huge misunderstanding. Oh and it was an 08 too to be precise.

Jake; we have an 08 Bluetek, bought new. So far we have had NO repairs required. We have done all preventive maintenance by the book. The car is lightning fast to me but my benchmark is a W123 diesel.

It is a great place to sit but I agree that the thought of having to access anything in the engine compartment for remove and replace is the stuff of nightmares. I still prefer driving and maintaining my 300CD.

Yes the '07 and up W211 Diesels have a lot crammed under the cover. Although not quite as DIY friendly as a W210, they still have many DIY serviceable systems. My friend has an '07, and I have serviced everything (I am not professionally trained) except the DPF (I may buy the kit from Pelican to do it next time) . They did have the instrument cluster fry because of using it to jump start another car, and it had to be sent for repair. They seem to be very reliable cars. Other than the oil cooler seals, there aren't any major things that go wrong with them. I am partial to the '05 or '06 CDI, and may not ever go further up the food chain ('07 or newer). The CDI's seem to have the best of everything, and I am very happy with mine.......Rich

Bluetecs have AdBlue, which I really don't hear about many problems with. The oil cooler thing is labor intensive but a member here put up a really nice DIY, while time consuming it looks totally doable.

What no one wants to talk about as we drive our CDIs around and talk about what complicated messes the bluetec cars are... bluetecs do not have SBC. Something to think about.

Not all have AdBlue. The V6 in an '07 (and later) is called Bluetec, and does not require AdBlue.

They are quick as all hell, but I'd rather maintain my w210s and w124s because of the simplicity.

That's good to hear. I do plan on picking up one of these cars, so that's good to know. I also don't believe that I'll ever go past an 07' Mercedes. Too many computers and too much technology. I hate computers.

I've heard the SBC system is a nightmare in the S-Classes. What's the big issue with them? The oil cooler thing isn't too big of a deal. If that's the major issue with the car, then that's fine with me. Also, like RollGuy said the 07 I drove was the last year before the AdBlue urea system.

Adblue first appeared in the diesel W211's in 2010 models in the US market.

S classes didn't have SBC. W211s before 2007 did. So do you want the v6 "complications" or do you want to deal with SBC. That was my point.

I too would like to know what the big deal is about the SBC. I do know that special precautions need to be taken, even when changing brake pads. I have heard that when they fail, they fail expensive. Other than that, I am enjoying the GO as well as the WHOA in my CDI, SBC or not.
