Hi there,

First time poster, so hopefully this is as proper as I can make it. *I can post an autoscan, but I cannot communicate with 09 Central Electronics, and Autoscan hangs at that module*

I was adjusting Byte 18 in the Central Electronics module to see if I could find a code that worked with some aftermarket headlights for my 2012 Passat SE (2.5L, North American Region). By default, the turn signals are on (at a reduced brightness) with the low beams, and ultimately, I'm trying turn them off completely (but still function when I activate the turn signal).

After trying numerous different values for Byte 18, I entered FF, which turned my car into a total light show (exterior lights, interior lights). Now I cannot start the car (tries to turn over but doesn't start), or access Central Electronics again. Battery voltage is approximately 11.2V.

Does anyone have any idea how I can revert back to the factory settings without currently having access to 09 Central Electronics?

Thank you in advance!

11.2V? I would start by connecting a battery charger. ;)

Ok, I don't think the battery voltage was the issue. I put it on the charger (got up to about 12.8V) and did not fix the problem.

With ignition on, door lights, low beams, interior lights, etc all flash twice per second. Battery drain is pretty substantial (estimated 0.25V/min), and still cannot communicate with 09 Central Electronics (auto-scan hung on that module). I also cannot lock/unlock the doors with the fob or buttons inside the car. Auto-scan below:

Changing codings in a module with battery voltage down in the mud could very well cause problems.

Next thing I would try is cold-booting the BCM. Either disconnect it from the car's harness for a while or disconnect the battery for a while. No guarantees that this will fix anything, but it costs less to try than a new BCM. ;)

Thanks for the quick replies Uwe! I disconnected the battery overnight (just positive terminal). Is there a fuse tied to the BCM? Any other ideas?

So I guess I will order a new BCM?

Personally, I don't have any other ideas.

VCDS does warn you that fiddling with byte 18 may cause malfunctions that in some
cases cannot be fixed except by replacing the module.

Any idea if making changes in the BCM can affect other modules in the car? For example, could it affect the CAN gateway, or ECM, or some other electrical control module?

Update:

For those looking at this in the future, it was just the BCM that was fried. Replaced that, and all was mostly good. I am having issues pairing keys, but I think there is lots on the forum to troubleshoot that.

Does anyone have the stock 09 Central Electronics long coding for a 2012 2.5L Passat SE?

Look in your Scans sub-folder, perhaps you did an Auto-Scan before you bricked the module?

Or look for for the CodingLog.txt file; it will likely have some, if not all of what you're looking for.

If you don't have either of those, the closest data I have handy is:

2012 Poverty Spec 6MT TDI:
Code:
Address 09: Cent. Elect. (J519)       Labels: 1K0-937-08x-09.clb
   Part No SW: 5K0 937 085 P    HW: 5K0 937 085 P
   Component: BCM PQ35 B+   011 0047  
   Revision: BH011001    
   Coding: 6F200EB8F82B28D408880001360004C84071008E50A00560648060000C70
   Shop #: WSC 09003 957 00200
2013 TDI SE with Sunroof & Nav:
Code:
Address 09: Cent. Elect. (J519)       Labels: 1K0-937-08x-09.clb
   Part No SW: 5K0 937 087 AA    HW: 5K0 937 087 AA
   Component: BCM PQ35 H+   121 0168  
   Revision: BL121001    
   Coding: 6F200E1B802B2AD408880001160085480071008640A00560648060000C70

Thanks for the help Uwe! From what I can tell, this is the original coding:

2012 Passat SE 2.5L w/Nav and sunroof

5K0 937 087 P
6F200E1B902B08D408880001160004480071008640A00D60648060000C70
