If the 08's and 09's could stay in S mode, there has to be a way to update the software to be able to do it in any model. Now to find the setting. We need a CS major in here!

 

All 08's and 09's will remain at S or C mode, depending on the setting that you were last on when the car shut off.

2010 is the first model year where MB defaulted to C mode upon start up.

2010 was a transition year. P30 was offered until December 2009. P31 became the default option at the beginning of Jan. 2010.

I hope this clarifies any confusions.

 

So ym10 pp cars mfg up until 12/09 would have lsd as part of pp and later ym10 pp cars would have had to option it in.....I would assume

 

A quick way to differentiate the P30 vs P31 cars are the red calipers. Alcantra wrapped steering wheel is another way, but not all P30 cars were spec'd with Alcantra wrapped steering wheels. Since you have an 09 car, you definitely have the stiffer suspension and lsd packaged performance package car.

 

If you have access to a xentry/DAS developer system, I think you can change the settings in developer mode.

 

Have you tried it before? If that's possible, I'll have it updated.

 

I personally haven't tried to do the developer programming, but can check it out on my das system and get back to you. im pretty sure I read about it though on another forum.

 

If you ever get around to it, let us know. It would be awesome to be able to start in M all the time.

 

The W204 is covered under Xentry and not DAS and developer is not available through Xentry. I think that is why only 2009s have been modified using DAS and you have to have an older version of DAS to get any W204 coverage. Not an expert but that is how I undrstand it.

 

mort, you can access w204 in das developer in 2012 and prior versions of das/xentry. w204 has to be unlocked which can be done with a passcode or enabling it as a prototype vehicle in earlier versions. there's a lot of threads about this on *******.


there's a video that kind of explains this (using das for w204, not the startup mode specifically) on youtube:

 

Haha....
