Backstory: 2011 JSW. DPF light was on along with other associated engine faults. Fixed problems then drove highway while monitoring progress. DPF light went off, we (I) cleared all faults. At that second, the RNS-315 clock was gone (black screen) Will not power on holding power button and eject. Now the sunroof, sunshade and interior courtesy lights do not work properly but I believe they had been. The roof/shade will respond to recalibrating but and indicates as learned, but do not operate by controls.

We have driven 200 miles with no engine code faults. Everything else on the car seems to work. GPS, Instrumentation, Lights

Here is what we have tried:

Compared earliest and latest scans for the coding for each module. (No differences)
Re wrote original coding for some modules. 09,19,2E,37,4F
Tested every fuse in both engine and passenger fuse blocks.
Checked fuse and power for RNS-315
Looked at BCM and the attached relay connections for signs of corrosion.

The Memory checksum has been present for some time, long before this problem so I didn't consider it a cause.
The ABS TPS comes and goes.

Considered a ground problem but the infotainment blacked out during the fault reset.
But VCDS showed the memory size in the SD card. The card is now removed.

What am I missing? Pretty Please...

Will clearing all DTC/faults cause some systems to stop working?
I cannot imagine how or why. I mean, you're buy no means the only person with a car like that who has cleared DTCs, but you're the only one I'm aware of with this issue, so my money is on: This is a coincidence, and I've seen some strange ones, but the cause is something else, I'm just not sure what it might be.

cleared all faults. At that second, the RNS-315 clock was gone (black screen)

Something odd here

56-Radio -- Status: OK 0000
But then nothing for 56 - Radio in the scan ? Scan stops at Module 52 ??
Address 37
Address 37: Navigation (J794) Labels:| 1K0-035-27x-37.clb


2 Faults Found:
1048669 - Tuner for Satellite Radio
B11CF 53 [00001001] - Deactivated
Mileage: 174892 km

1048642 - Internal Control Module Memory Check Sum Error
B2000 42 [00001001] - General Memory Failure
[ECU defect data memory failure]
Mileage: 128285 km

Does this have a Satellite Radio ?? What is Satellite Radio ?? - Sorry I have never needed to know !

I note that Tuner for Sat Radio is deactivated - Deactivated where ? In Gateway ? In Coding ? Can you check ?

1048642 - Internal Control Module Memory Check Sum Error
B2000 42 [00001001] - General Memory Failure
[ECU defect data memory failure]

That there seem to pointing at a dud unit yet you maintain Sat Nav is functioning ?
1 Fault Found:
01512 - Control Module for Sliding Roof
005 - No or Incorrect Basic Setting / Adaptation - Intermittent

Mileage: 174892 km
How the F can "No or Incorrect Basic Setting / Adaptation" be intermittent ?? Not logical !


Also look at mileage in the Freeze Frame for the faults !

The Sliding Roof and Satellite tuner faults set together.



Go disconnect the battery for an hour. Reconnect and Rescan please.

Once again:

These cars do weird things.

For example a 2024 Vauxhall / Opel Corsa which is a rebadged Peugeot. I have experienced this more than once !! It is scary !!

If you disconnect / reconnect the battery it will then not start. Often Lock unlock will sort it but not always. Clearing DTC's will bring it back to life.


Agreed - Clearing codes with VCDS is not likely to cause this. This is a 2011 - 15 year old car. Any issue of this nature would have manifested a decade ago !!

It's a NAR market thing. Sirius/XM satellite radio. That fault code is just advisory, indicating no active subscription to the service.

How did you clear codes? Direct in 01, or [Clear all DTCs] in the Autoscan screen?

Great News I cant believe it. We put the car in transport mode for couple of days. As soon as we took out of transport more EVERYTHING started to work.
We had to enter the radio code and relearn the sunroof and sunshade. But everything seems to be normal. Thank you.
