How to enable Dyno Mode (Instructions In Post)

In the 2007-2008 S-Classes, put the key in the ignition, turn it to position 1, or with keyless go push the button once without having your foot on the brake. Then at the same time push the accept call button and OK button and hold them both for a few seconds...then your in. Im sure you can figure out what else to do from here

This way you should be able to read the battery voltage too. I once tried it quickly but couldn't get to the menu. Perhaps I passed the allowed time or something. Did you make it?

Actually tried it again today and it worked first time.

Dyno mode is mainly intended for testing the car on a dynamometer, where only rear wheels move. All ABS/ESP etc. features are completely switched off in order not to interfere with dyno or similar testing.

Definitely not intended for normal driving.

Do you have to turn it off manually as well in the newer MBs? The other ones that do it, when you're in dyno mode, you're in it until you manually go back and turn it off.

Probably...but idk about your engine though. But we dont have the CDI engines where I live(On the S-Classes), so I dont know about that...but if the surface is wet or slippery, probably.

The S320CDI has the same gear and rear differential ratios as the S500, not sure if the US S550 has the same. The engine torque is a bit higher on the CDI (in practice the same, 540 versus 530 Nm) but the CDI makes it at a lower RPM.

At first gear, the CDI should actually have more torque (and power) where the rear wheels start to burn rubber. I haven't tried it, and will not, but I assume the torque converter would not allow engine RPM go high enough where the S550 would make more HP compared to the CDI (even 320). Here I mean the case of burning rubber, car practically stationary and rear wheel "speed" pretty low.

On a normal acceleration, the CDI should do the same for the very start but once engine RPM would go above 2000 or so, the S550 would start accelerating faster. I actually looked at the engine power/torque figures, at 2000 RPM the 320CDI has more power than the S550 at 2000 RPM, at 3000 RPM S550 is marginally better, the CDI would stop doing better at 4000 RPM while the S550 really gains a lot more power beyond 4000. This is why the S500/S550 makes a lot better for 0-100km/h.

The CDI would beat the S550 at the point the tyre first loses it's grip and from that onwards should be "easier", I would not be surprised if these two cars burn rubber the same way. Anybody willing to try

Not really what an S-Class is about but has anyone tried the Brabus Diesel tuning box for the 320 CDI? Seems like a pretty usefull hike - 37 hp and 50nm.

or theres this mob who say 51 hp and 85nm

Keep telling myself it's not in keeping with the type of car..
