2014 vw jetta TDI came with a 086J BCM and I upgraded it to a 087J without any problems. The remotes paired as per rosstech's website via vcds. I recently installed a 090E BCM and I tried pairing the remotes again, and could not get the same procedure to work and even tried the manual way of pairing. It still didn't work. I thought, well, maybe after I have the newer instrument cluster installed and the new canbus wires added, the problem will rectify itself. Well, no, it didn't. Manual way does nothing. When I try through VCDS, it acts like its going to work, but when I set it to adapt a key, VCDS reports lost communications to the BCM. I tried 2 BCM's, one is a 090E, and the other is a 189. They both do the exact same thing. Is there something else I need to do? Everything else works fine with the car. Ignore the Info-mation system error, since I have a hardware fix on the radio. Also ignore the telephone error, I just need to pull that module out. Terminal 30 errors I am familiar with what I need to do, but would like to tackle the remotes first, unless, of course, the Terminal 30 errors are causing my problem? I doubt it though.

This is the dump from a good working 087J BCM:

Are your BCMs and keys all 315MHz? New or used replacement BCM? Factory mode off?

If You're missing power to pins of bcm, I'm not suprised it doesn't function 100%.

Agree, but these open circuits only apply to the lighting so central locking should be OK

I acquired this info from a vw polo website which was posted by those with european cars:

"BCMs with 434 MHz radio carrier frequency ends with the letters B, D, F, H, K, M, P, R, T. Pick up one of these if you are looking to upgrade. These BCMs are used in India, EU, South Africa and Russia."

So all others, I'm assuming is NAR. The bcm came from a NAR car, so its safe to assume its at 315Mhz, the keys are stamped 315Mhz also. Not sure about the 189 bcm, because it doesn't have a letter at the end of its part number, so I'm in the process of acquiring another 090E bcm. I haven't seen versions 90 or higher with anything other than E? Since the 2 bcm's behave exactly the same, I doubt the replacement bcm will help. These bcm's are used, so that is suspect.

Thanks for the help.

7E0 937 090 E is for 433mhz

and you are wrong thinking "other index" is NAR
All other index can be India, or even discontinued item and ETKA not have them in history record
if Etka show - is 433 = 1000000% is 433
in a fact it exist in POLO, so never been in NAR , only "old land"

Also - if you want install BCM after 2018 (accoriding to ETKA) remote key 50/50 will work
from 2019 VW removed "remote match" via BCM
Remote AND KEY is match automatic while Keylearn to cluster - yes - REMOTE and KEY (new cluster with new coding in immo 000002)
for example VW T6 from 2018/2019

Thanks for that info Spacewalker. The two BCM's that I have tried are 7H0937090E and 7E0937189, which came from NAR cars? If I am wrong thinking these are correct, could you point me in the right direction? What part numbers could I use? 2014 vw jetta tdi with cluster part # 5C6920974F.

I looked on ETKA and its saying all 090's are 434Mhz? If thats true, it might be easier to change my keys to 434Mhz and adapt them to the cluster.

Ok, the replacement BCM did it. Could of been the BCM was bad or something up with the coding. There is some differences in the coding, but I can't find any documentation to tell me what they are. I know in my vcds tool it tells me to NOT change them. Odd...

one that didn't work:
Code:
7B994F3808AB0B0000382600240884C40082502E60000000300050002000

one that worked
Code:
7B994B3808AB0B0000382600240884D500C2702E60004000300010002000

I modified the new (used one) BCM with the least amount of settings to make it work. There are differences in the byte string that I'm suspecting change the frequency of the internal radio channel for the remotes. Not sure which one though. I encountered a multifunction steering wheel problem and a turn signal problem with the coding of the new BCM with those bytes that are undocumented, so i kept copying the old settings until it worked. The settings that didn't seem to have an effect, I reverted back. One thing I noticed was byte 18, on the one that didn't work was 50 and on the one that worked was 70. VCDS says to not change this, so I didn't. No idea what this was for. I'm suspecting this was the problem.


Hope this helps someone who encounters something similar.

By all means, don't take my information as coming from an expert. I'm a novice at best. I enjoy modding though. With proper documentation, youtube and these forums, anything is possible, just have to be persistent.

I reinstalled the 2 bcms I had and coded them identical to the one that worked and it was a no go. I bought 2 bad bcm's off of ebay...
