Information electronics restarts / shuts down

Hello everyone,

I hope someone here can help me.
My radio/navigation system in my Sharan has started turning on and off repeatedly.
After sending the device to a repair service, the diagnosis was that it could not be repaired. Since a new one costs over €1500, I found a replacement part from a parts supplier. However, it is Revision D, not Revision B.
The component protection could be replaced at the dealership, but now none of the features work, such as the navigation system, hands-free calling, or anything beyond the radio.
My question is, can this device actually work in my vehicle? Encoding was taken over by the faulty component.
Here's the Autoscan result.

Thank you very much for your efforts!

Best regards,

The first thing I notice is that the battery voltage is too low, at 12.15V. That could also be the reason why there are so many error entries.
Why is the address for the radio not available?

Hello Andreas,

Thank you for the response.
I cannot answer your question about whether there is an address for the radio.
When checking the voltage, I need to check the battery.
Nothing is displayed, neither the PDC (Park Distance Control) nor anything else.
Right now, only the radio is working.

Why don't you go back to the dealer and report the problem? Who installed the radio? Is it connected correctly?

Hello,

I was already at the doctor's for several hours yesterday.
Tomorrow, I'm going to try again, let's see if everything works out this time.
I just wanted to check if anyone is familiar with this.

Hello, please perform component coding and restore function activation.

Best regards, Dago.

We don't know what the "Freundliche" (Friendly) person did, or what they should have done. But obviously, some steps are missing, otherwise the complete functions would be available.

Hello everyone,

Here's a quick update. The navigation and Bluetooth are now working. Unfortunately, the PDC (Parking Distance Control) display and the traffic sign display in the navigation system are not working.

Whether this can be fixed with software or coding remains to be seen.

SG

We can only guess here. All we know is that a Revision B was swapped for a Revision D. We don't know if it's an RNS 315, 510, or something else.

PDC is definitely a coding topic, as it doesn't require any additional cables.

But for that, we need more information, or even just an automated scan that includes the relevant component.

Hello.

Okay, I've attached the initial scan report to my first post. It shows so many errors because I always disconnected the fuse to protect the battery. The "Radio" boat got stuck in a loop.
It's about address 5F.

Code:

Adresse 5F: Informationselek. I (J794) Labeldatei: 5G0-035-MIB-STD2.clb Teilenummer SW: 5C0 035 680 B HW: 5C0 035 680 B

The device was beyond repair, so I looked for a replacement part that was reliable (protected component). That search only turned up the part number 8C0 035 680 D.
It works fine overall, except for the parking distance control (the graphical display on the "radio" screen). As well as the traffic sign display feature in navigation mode, which appears on the "radio" screen.

The encoding is identical to that of the B and D devices, and there are no errors in the memory. I can run an Autoscan tonight and send you the results later to show you how things are.

Am I understanding correctly that you replaced part B (defective) with part D (now newly installed)?

The scan is from the old one.

The RNS510 was essentially in production for about 10 years and was often revised during that time. Just between the two generations you're talking about, there's a different display generation, and of course, there were a lot of firmware updates. It's possible that there are some "incompatibilities" due to software versions.

What does the coding say about the PDC (Parking Distance Control) display?

Hello.

Unfortunately, I haven't become any wiser.
As far as I can tell, everything seems to be okay with the coding.
The OPS (Obstacle Pre-Scanning) feature is active in the parking sensor coding, as shown in the Screenshot. Reordering the values didn't make any difference.
There's nothing to find in the "Radio" section of the encoding, but there are a lot of adjustments there, although they are incomprehensible to me.
As far as I can tell, the firmware is the biggest difference between the devices.
The "B" models have firmware in the 200s, while the "D" models have firmware in the 300s. A change is not planned by VW.
My friend is checking to see if he can get anything else.

I just ran a recent car scan and have attached the results.

Thank you for your efforts!

SG

Hello,

I also find it strange that the car scan doesn't show a radio. Do you not have a previous Autoscan?

Did someone with technical expertise disable the radio in the gateway's configuration list (control unit address 19) in order to make existing errors "disappear"?

Best regards, Rainer.

Hello,

Here's a log from November 2020.
There's no more radio like I understand it.
Everything is now categorized under "Information Electronics," but I just use "Radio" because it's shorter.

SG

Hello, it's also possible that the radio is not supported by the device. The manufacturer often provides very little information about this, so you usually need to contact the TV manufacturer or supplier directly to get any information. For that, your friendly contact would need to take some time.

Otherwise, your VW workshop could try to obtain a build-state documentation for the 5F model (if that's possible) and also use an online software configuration tool. Perform steps STG. 10, A5, 19, and 09.

Best regards, Dago.

Okay, that's a shame. Thank you for the feedback!
