Yesterday when I was heading to the track, drivetrain notification appears on the screen, and the full performance not available.

I turned the car off and turn it on again and it's gone.

So I took it to the dealer today and hope it's a small issue.

Also to be honest I was driving the car hard and it was in sport+ mode.

If anyone faces the same problem or know anything about it please let me know.

Thanks

Same here, SPORT+ and hard driving 180-200 for about 10 mins. It disappeared after restart the car so i haven't went to the dealer yet.

Since you post here, I assume you have mods.

Extreme heavy load with freer flow exhaust system on stock tune causes this problem if you search you will find more threads on it. It appears more MY2016 cars suffer from it.

Yes this is exactly what happened!

They said that they need to re-program the car and will update me on Saturday.

Yes it has an Akrapovic exhaust with catted downpipe, the service advisor told me that it's from the downpipe and they need to re-program it but it will not be under the warranty :

They offer to reprogram to your aftermarket part?

No, they said that they will remove the notification in the system by programming.

I'm not sure about it, because here in Qatar we don't trust our dealer :

Why u have to reprogram it? If its gone after restart. Did the dealer detect other problem more than a drivetrain error?

I haven't went to the dealer yet because the car drive normally now.

Because when they checked the system they saw that there was a notification and they said that they need to reprogram it to remove that notification.

And they said it's from the downpipe and I think it doesn't make sense

But at the end they said that they reprogram it under warranty and everything is fine now, also I would like to ask is your car stock or modified?

Thanks.

Guys, read this topic and you know a lot more... I had this reprogramming done by my dealer. I still need to test if the problem is gone.

Was the car low in fuel ?

Same here! Get your software upgraded and retest.

Nop, It was filled to the top, and we raced a bit on the highway before getting to the track.

Although for the first time, as I couldn't fill it with proper fuel I inserted a can of NOS booster (street formula). So not sure if different fuel caused this.

But anyway as @MR. suggested, I will get it to dealer and ask for PUMA update.

Why would you post this without bothering to explain how you modified your car?

Read my previous, where I mentioned all the mods.

Octane booster shouldn't cause this, and I did another run with the same fuel just with 1/2 of left in the tank, and the error didn't pop up.

I got this as well.. 6th gear, around 6k rpm and got the fault... 3rd time already. x less dp on stock exhaust. e30 95oct. jb4 on map 2, bms intake and Vargas interc.

The fuel tank was half with boostane (octane booster), our fuel has low octane unfortunately

I have mentioned earlier what is the modification on the car in the 5th post.

It has an Akrapovic system with catted downpipe and drop in BMC filter

Has anyone experienced this with other exhaust systems?

Not with other exhaust systems, but people have experienced it with other downpipes than the stock one.

It has to do with the more free flowing character of the downpipe and the on board systems giving overboost error messages.

So if planning to track the car we shouldn't install any down pipe even the HJS 300 CEL?
