when i took the one out at the dealership i had it pegged at the speed limiter.. i think it was 132 mph ish... that was fun

I never thought I would see something that could out torque and out horsepower a good old fashion GM engine. Typical gasser engines always have to give up something. Not on a CDI. I think it is a great brand for DC to keep up and it is a mistake they are not going to use that emblem on the Jeep Grand Cherokee. I got the only two speeding tickets of my life in 2005 within 3 months of each other and they were both soft too thank goodness(one of them thanks to a state trooper who could have nailed me). But I got both of mine in my GM v-6's. I'll make sure if I get my CDI I will get one of the heavier ones that the engine can't quite accelerate as fast.

Don't count on it, S420cdi's are the bigger/heavier one, and they develop even more power! (its a V8 diesel!!) :eek: These are performance diesels, they can beat gassers of equal size. I'd give anything to take a 320cdi out for spin.

WOW to CDI
 

In July I purchased a new 320 CDI. All I can say is WOW!!!

I do miss the little clatter of my 300SD --- yes the 3.5L but the torque, on this new one is something to be careful of.

I don't who got the speeding ticket but I can easily see how you can get into trouble very quick. The first time that I passed someone on a 2 lane road I was used to punching it. Well I did and before you know it I was doing 95 mph.

The ONLY issue that I've had with the car is the windshield wippers. They make noise. I've contacted the dealer and should get them adjusted fixed at my 13K oil change. Other than this minor issue the car has been fantistic.

On a long trip 300+ miles the computer was consistently at 38.6 MPG with an average speed of 78 MPH. This sucker was meant to be on the road WOT 24/7!!!

All the best

3 point star

The jury is still out on the new generation of CDI MB's, the real question is once one get passed the 100K and lose all warranty protection, how are the owners going to cope with the cost of dealing with electronics on this, essentially a computer controlled automobile.
This is already happening with 700 series BMW, from what I hear once the 740/750 gets out of warranty you simply can not give them away, no one wants expensive trouble.

Mercedes does not allow anyone to run more than B5 (5%) in any CDI.
 

Sorry but I have to disagree with this blunt statement, do you officially represent Mercedes Benz?
I own it. Because of this Mercedes Benz has no legal right over what I do with the car, heck I could even put spinner wheels on it if I wanted to. Also what basis do you have of claiming that M/B will void the warranty if they find more than 5% biodiesel in the car? By your claim they would void the warranty pre-emptively even if I had no warranty claims or issues.

That is 100% true. It's your car, do with it what you wish. Just don't expect MB to fix it on their dime if your alterations are the cause of the problem. If they can prove that your alteration is the cause of the fault, they have every legal right in the world to deny your repair claim. They designed, tested, manufactured, marketed, sold, and shipped you the car. All you did was pay them for it. They know the limits of their car, that's why they only want B5.

If you bring your car in for new brakes and they find B100 in your tank, BAM!, they CAN void the engine/fuel system warranty.

I do not represent MB, I'm talking common sense. If you violate the warranty statement that you signed when you bought the car, then you are on your own. Pretty simple concept.

Just because you can does not always mean you should.

That is why you bring in your car for dealer work with diesel in the tank.

Fools the VW guys everytime we take it in for warranty work.

Yep. Sometimes you just gotta play the game. :)

If you put Biodiesel in it and if that is a no-no according to MB (I don't know the official stance), they could only void your fuel system warranty. Not your body/suspension/transmission and all that. They'd have to prove that the biodiesel caused a problem in those areas...so no way that's possible.

And I'm not sure if they're allowed to flag your vehicle as warranty void, would the dealership just say, sorry we can't work in this.. and you could try another dealership? Or would they tag your VIN.

If you can afford to fix it go for it. Seems pretty pointless buying a $50k car then trying to save a few cents on fuel?

Just don't get annoyed if MB denies warranty claims.

Its not about saving a few cents on fuel, at least not to me. Its more of an enviromental aspect. Not only that, but i hate when i leave soot stains on the driveway due to diesel. And as said many times before, your not at risk of mechincal problems if your run quality biodiesel. The same can go for diesel as well, you can also get some bunk diesel fuel with to much water in it and mess up your fuel system.

MB still wont cover it under warranty though as you ran bunk fuel through the car. Bad fuel is bad fuel.

Cant say for sure, but if they are anything like VW all theyll do is deny your warranty claim. You can easily go to another dealership. There was a thread on the TDIclub of a guy whod been having in-tank pump problems with his TDI. So he brought it in the dealer with diesel fuel and the dealer tech's claimed "there was biodiesel everywere!" He had them do a fuel test to prove that bio was in there, $400 test showed that only thing in the tank was diesel. But they still denide his warranty claim for having mentioned using biodiesel before.

So he took it to another dealer and they fixed the problem as he didnt say a word of bio, they didnt flag him or anything. Just didnt want to cover it at that specific dealer.

So if your going in to the dealer for service, bring it in with diesel and keep your mouth shut!

Simple as that:)

New cars are pretty clean, I'm not to worried about the environment.

the new S-class is more enviromentally friendly than the prius
