Hello, 


Im gathering all the parts to retrofit 5DP Park Assist, but I'm having a hard time buying a JBBF used on all these parts markets.

Most advertise a part number that is not real with the number displayed on the parts.
This is also not new as they do it to try to sell without caring with returns. 

But the weird part is, in 20-30 adds I'm only able to find one of the part numbers


A example :










Cant find it anywhere.
How to extract the part number is not easy, but on some parts its easy to spot others the numbers are weird combination.


What I'm hunting
JBBF (Junction Box Electronics Front) 
The version without Park Assist has the PDC ECU built in. 
JBBF PNs:
61356992414 (07/01/2017 — -)

61359393665 (03/01/2016 — 04/19/2018)
61359384212 (07/01/2015 — 12/22/2016)
61359361114 (03/01/2015 — 03/10/2016)
61359353417 (07/01/2014 — 08/06/2015)
61359345320 (03/01/2014 — 07/03/2015)

If anyone could advice how we can decrypt the front or where we are able to see the part number would be great. 
In some we have a  "SN :" others we have "s:" or maybe there is another combination.
