I bought an E63 with a February 2007 build date. The off-the-line performance seemed a bit sluggish. Apparently Mercedes knows this, and has a very recent software update along with a new throttle valve for the transmission. I had that done.

With the latest, the car will leave rubber when cruising at 30 mph in first gear (manual mode) when you stomp down on the pedal with ESP off. I can repeat this every time.

From a dead stop in first gear, sport mode, ESP off, stomp the pedal and the car will leave 50 feet or more of rubber.

Before the update, I couldn't leave rubber from 30 or from 0. The overall acceleration seems the same. It's just that the transmission seems much more responsive.

 

I haven't heard of this. This is good news for 63 owners!

 

build date for our 63 estate wagon is dec 21.... paid for the P30 !!YAY!!

 

Nice KJ, they're building it on my B-Day!


Just for that, you need a decal, JIMBOMOBILE

 

Can't wait to get mine updated as well.

 

just put in dyno mode, if you really want to replace your tires in a few days.

 

How do you do that?

 

I had a check engine light and took car in to check at 3k miles. They replaced the "switchover" value and now a whole new car. It is noticable faster and the tires light up easily. Great deal

 

What all does dyno mode do?
