Transmission software update?

This is my theory, these boxes pick up driving style and habits over an amount of time. they can possibly be over sensitive to driver input. TCU update could improve this . Wipe the learning technology clean. And start fresh learning carracteristics.

Is it worth it. This is what I'm trying to gather.

I don't actually know if the TCU update erases the previous learning. It may or it may not, but it's not obvious either way.

In any event, the TCU learning is a dynamic process, and if you change your driving style then the TCU will quickly relearn - there's no particular advantage in erasing the previous learning.

(Not to be confused with Adaptations, which is a different thing altogether).
 
One thing I did notice and the reason for asking for the update was due to a bit of lag. I now realise that the lag was probably turbo lag, but since the update I hardly ever notice any lag.
Last time I gave it extensive use of the paddles was when at Carlimits for the day but that was with traction control off and not under normal driving conditions. If you're ever down this way you are welcome to give it a drive using the paddles.


I have read the TT engine can lag at certain rev range. On the US forums more the case.

Thanks for the offer. I would be happy to have a blast using the paddles.

Not confused at all with adaptions. Well aware they are different!

Having a TCU update and adaption reset. "Might" be the answer.

What does a software update do to the TCU, this is what I would really like to know.

What the update does will depend upon which update is applied, and there may be several updates available which must all be applied to get to the most recent. Most updates will be to address specific issues rather than a general improvement

Your early posts in this thread led me to believe that you thought a TCU update would be a good thing, then you seemed to flip 180-degrees reading as though you think it’s poppy-****, and now back to being a good idea.

Find out which version you have now, which version is the latest and what the interim updates do (not just the latest). You can then decide whether it’s worth it. As suggested already be prepared for other updates to be bundled as control units are often interdependent.

Long winded post. None of the wiser 🙈🙈. I need a Brain update now. Or was it a TCU update. I'm so confused.

I imagine a TCU update on a 10 year old car can only be a good thing right ?

How would I gather the information on what version or software I have on the car currently. Could someone advise?

Cheers
 
Does anyone know of what is involved with a transmission software update. How much would it cost " ball park" figure would be fine. And is it recommended with the MCT transmission, considering my car was one of the first to have this transmission. Looking over the history an update hasn't been carried out on the car.

The transmission is all working spot on I'm just curious, would it be of benefit to have this done. What if anything can be achieved by having a transmission update?

Also who would be best option to carry out the update?
Cheers, Tom
been charged £60 for mine
 
Again, what's to be lost with inquiring regarding a software update!!

You've had a map on your car. Maybe a TCU update my be of benefit to your vehicle!
I'll take the advice of a respected indy like Alex and leave well alone.
My changes are millisecond fast and as he says, a software update could wipe the remap.
When my car was serviced last Sept I specifically asked them not to update any ECU for the exact reason of wiping the map.

If your gearbox is working fine, why have a software update that could leave it operating worse. Not all updates improve matters.
Those diesel owners having that Nox update aren't happy, and it can't be reversed.

But if you want to apply any update going, go ahead. Its your car.

You will need to connect the car to STAR to find out which version you have and which updates are available - the technician can confirm when they hook up to update it.

Like others, I personally wouldn’t update it if it’s all running rickety boo, but as @AMGeed said, it’s you car so do what you think is best.

Your car more than likely has the most up to date TCU software applied to it. Being only 5/6 year old.

My vehicle 10 plus years, and looking over the history, no obvious updates have been installed.

My gearbox shifts perfectly for my liking. I was under the impression if newer software was available it could improve it even more so. Which I personally imagine an update would achieve.

I need to find out exactly what if any updates my car has had.

And the milliseconds shift my car does as well but only in "M" mode 😉

More investigation work to be had on this subject for me and my machine 👍

So I'll need to book it in with a outfit that has star diagnostics. So do I ask for the TCU and ECU to be read and ask what updates are available?

Would a MB dealership be able to Tel me over the phone do you think. On what updates have been installed on the car?

Do you have a record of other software updates in your service history? I am a little fanatical about the service history record and I don’t have any records of updates.

Unless someone specifically asks for updates to be applied - like you’re planning - and they retain the receipt, I can’t think of another record of software updates.

I suspect that 99.x% of updates are applied as a warranty fix or as per of another repair, and as such wouldn’t be recorded, as far as I’m aware.

Please do let me know if it’s available by other means though.

I believe that a main dealer would need to connect your car to STAR and read each control unit to confirm versions.

When you book it in, just tell them what you would like them to do, ie update the TCU, but first tell you what the updates do.

It will probably my cost you the standard diagnostics cost, which at my local dealer is £110 (not sure whether that includes VAT).

Phillipe, showed evidence of just this on post #6!!

Maybe your cars haven't had the updates because you didn't request them?

I would like to know and want to know what updates have been installed on my car!! And have the paperwork to prove as much!!

Out of interest did you read the post you quoted?

I know he posted the receipt. He specifically asked that it be done, like you’re planning to.

Only a very small percentage of updates are specifically requested. Like I said in post #51 which you quoted...

I'll inquire tomorrow with MB and an indy or two, and see what's the best way to go with this.

You know so much you should have your own forum 🤣🤣🤣

Mr BD the forum Guru

I'm very disappointed you did t know the £110.00 was including vat. Come on man sharpen up BD Guru 😉

I don’t think it would be particularly popular but thank you for your vote of confidence.
 
Brentwood, Essex. I may give MB Chelmsford a call tomorrow. See what if any this update can achieve.

Thanks, Tom
Sounds like the start of a plan , depending on what they would charge , may be worth an Indy phone call after that
 
I've been in touch with a few, and majority are of the beliefs if it's all working in good order and nothing is causing any odd behaviour. Then go with what the car has currently.

On the other hand if there is updates available for my actual vehicle, then by all means go ahead and have the updates done.

I've contacted a Main MB dealership and left my cars information with them. I hope to hear back shortly if there are updates available.

It turns out there is a recall on my car, the lady I was speaking to, told me of this. I'm sure she said a knee adapter or something along them lines. A 10 minutes job according to her. She couldn't give me anymore on that at this time. The link wouldn't open for her she said. Very helpful lady I have to say. She thinks it's a software update.

So I'll wait and hear back some information hopefully.

Thanks for the contributions to the thread. It's appreciated.👍

Forgot to mention that speaking with the specialist I have been speaking to today. Informed me. Most have the diagnostics like star to do the updates. But are not legal to do so. As you have to be certified/ registered with an MB to carry out such work.
