Assistance Systems Error - Speed Limit Display (warning message)

[SteveP]

I Steve, i left my car for nearly 2 weeks at the London West branch. They done a reset but all errors are back again after 15 minutes drive. I am so angry they didn’t fix this issue. How did you know about it ? Is there any update?

At the moment, most Centre’s are likely unable to provide immediate fixes due to there being limited functionality (not due to error) with the vehicle Software Testers.

What is likely the case at the moment is they are carrying out guided fault-finding at request of the Technical Dept & Porsche GB/AG and feeding back the results for Technical to work with the Software Team in Germany to build a patch to fix it.

The fact that immediate fixes aren’t available also leans heavily towards it being a software-based issue, as if hardware you could replace a sensor (pending availability) and likely get your desired effect.

I’ve had experience with similar issues with other vehicles and have - for my sins - worked in software previously. I’ve spoken with friends in the industry to get some insight into a broader range of the goings on with new Macan EV experiences and I should say these issues are relatively limited, with most new Macan EV’s working without a hitch. It seems to be when introducing Adaptive Cruise/Innodrive that things go awry.

Would be interested to know if anyone is having issues just with the standard Cruise Control.

Hi,

Add another one to the list, London based, same issues as above.

I have to say the dealership is doing well to support me through this.

Can i ask which dealership ? Mine is in the West London Centre

+1 Also London based. I was told by my SA (Porsche Centre Mayfair) that a prevalence of this issue is being reported in London (or maybe other cities) on roads where roadworks are taking place. Not really sure how this would impact the car but will drive the car to quieter roads over the weekend and see if the warning signal disappears. In any event, a software fix is needed. He did not have any news on that.

I am still having the same issues. My dealership has passed it back to Germany.

There is same issue on Q6 etron, and Audi has confirmed there is a software glitch.
On the Q6, the software tends to read road signs in mph and process them in kph (or the contrary). This discrepancy causes the inboard systems headache… and so it disconnects assistance systems.
It seems Audi will roll-out a big software update by mid November, and it will be installed at the dealership (no-OTA will be very costly for the VW group…).

Macan 4 with Innodrive, picked up 31/10.

One day into ownership and have the traffic sign recognition fault (which is clearly intermittent but more off than on). The adaptive cruise control functions are the same, keeps coming back with messages that the feature is wholly unavailable and can’t be initiated and later works. Also getting intermittent errors giving an ‘assisted driving’ warning light and a ‘warn and brake assist’ warning light. That’s it so far.

Dealer claims were unaware of issues and had no problem with their demonstrators (none with Innodrive). However, did say another 4 with Innodrive collected the same day as mine has similar issues.

Will have to see what happens once one of the dealers technicians goes on a course next week!

 

[Diamondtrons]

Yep… More cars with Same issues
Mine has been with the dealership for 2 weeks. They sent a fault “ticket” to Porsche Germany and now waiting for instructions. They gave me a rental car… Pfffff… I only drove the car for less than 2 weeks ! I am so annoyed

Had this error for several days and different drives. Today it worked itself out, and functional again.

For some reasons i feel this problem is more specific to Uk and Innodrive ?

My Turbo is now with the Dealership for 2 weeks while I’m away so will give any updates I get from them. Agree this seems to be specifically a UK problem

Statistics based on this forum would suggest this…

No, I had the same problem last week here in the Netherlands. Also Innodrive and all the alerts that are mentioned here above. After a stop of half an hour, the alerts have disappeared and I haven’t had them since then. I’ll be alert and mention it if it’s coming back.

 

[MacanT]

I also have the same problem with my Macan 4 which I picked up last week. No Innodrive, no adaptive cruise control and occasionally not recognising road speed limits.

Please inform your dealership as soon as possible. The more cars they have with the same problem, the quicker they will be able to make a diagnostic and full resolution.
