CLA 45 Transmission Software Update In Progess...

So my car is currently at the dealer getting a transmission software update. I can confirm this mysterious update does exist. What it does? I don't know.

But I've heard that it does improve driveability and it apparently engages 4Matic more, including off the line w/o launch control. I'll give you guys updates once it's done.

making changes to increase the life of the transmissions. dont expect anything more aggressive since you will be disappointed.

which dealer did you take it to? last time I took it in, they said that no update was needed, so maybe I should try another dealer and hopefully they'll be mod friendly as well.

Confirming this next week. OETuning isn't convinced that I have the GLA45 TCU program update for the CLA. So we're looking into it. I'll have an answer soon.

Thanks,

The below was posted on the AMG PL. Apparently the 4Matic system is locked 50/50 when in ESP sport or completely off. Maybe improvements are when in S mode with ESP on?

[MBUSA William Vetter;1617321]The 'performance map' of the variable 4MATIC system is different in each of the modes...so in:

- C the focus in to provide a performance drive but with the highest efficiency, meaning that it will try and keep 2wd as much as possible and typically only send power to the back axle when front wheel slip is seen or the vehicle data (G forces, steering angle, etc.) says that power delivery would be better/safer with more power going to the rear axle...in this mode the torque bias is full variable

- in S the focus is on performance so there is a lot more bias sent to the rear not only re-actively based on what the front wheels are doing but proactively based on the vehicle data and how you are driving the car...in this mode the torque bias is full variable

- in ESP Sport & ESP Off - the torque bias is locked at a static 50/50 front to rear.

I asked about any transmission update and got the longest blank stare. They then told me that any updates are passed down through. But as of lately no updates.
