slow performance
A few weeks ago I become owner of 2007 R320 CDI. I have noticed that car a little bit hesitate to accelerate and I am wondering if any software update could be performed on car to solve that problem. When I press pedal, I fill that car doesn't respond on that (I used to have E320 CDI and I didn't have that problem) - it does take ~ 1 sec to respond on that event. In my dealership, they told me store that engine is going through regeneration mode and it is normal - I cannot believe but I'd like confirm it here ...
Also, I have installed Kleeman box but I don't see big difference..?
What I should do ..?
10x thanks ..

I sent e-mail to my SA asking about all TSB performed to car. I am just wondering if ECU could be programmed to the latest software. I am going ask what it is the current version on car and I can compare it here ...
I used to drive E320 CDI and it was much, much faster ...

Every auto magazine review I've read on the R-class diesel mentions an unnerving lag upon pressing the gas. Once on the boil, though, the diesel reportedly moves the car pretty well.

Could you please give me some link about it (tunekit). I am using Kleeman box (not ECU programming) and it did work excellent on my E320 CDI. Once I put on 1000 lb havier car, I don't see any improvement ...

zemun1234,
You can find what you need(power pedal) here: www.tunekit.com
Actually it won't increase power and torsion but only quicken up the pedal reaction, therefore, I think a ECU tuning should be done for better power output.

as I mentioned, I have Kleeman KD-Box and I think I am getting some boost (not as for E320 CDI) but I think my problem is TCU (transmission) software. I see Kleeman has ECU programming which it does modify both ECU and TCU. I am not sure if it does work 2,000 $ for heavy car as 'R' model ...
Is anybody there tried to do chip programming for R model ?

What transmission mode are you driving - C or S? I noticed a big difference between Comfort vs. Sport. I like the S as it's obviously peppier, but it also has more torque at low rpm and makes it difficult to stop/accelerate as smoothly from complete stock due to the brakes.
