I just received my C4 and 07.2019 Xentry set up from eBay. If you want detail on price and seller let me know.
I am trying to find the ATA version and change it to USA beep. When I go to control units>Body>Rear sam>control unit adaptations>read coding and change if necessary> I get the attached image. The ata version is not there. I have also exhausted the options in developer mode. I did find a ROW and US variant for PWM Ueff 5W.
Does anybody know how to enable beep when locking and unlocking?
I think we figured out in another forum (or maybe it was here, not sure) that there is an "alarm siren" installed in many markets of this truck, but not in the US.
It seems that the regular horn isn't used for the chirp. The alarm siren is.
So no matter what you program, you need to install a fuse and an alarm siren.
We figured the price was reasonable (can't remember but it was definitely well under $100) but I don't think anyone ever tried it.
Would be interesting to install the fuse, hook up a voltmeter to the connector, then lock the truck. If it shows voltage then you could go buy the alarm siren.
Look it up in a parts catalog.. or search around and see if you can find the previous posts. If you do it let us know how things turn out! There are quite a few people that would be interested in buying the siren if you can get yours to work (me included!!)
I was never able to get it to work. I think it required the coding PLUS you needed to add the anti-theft horn/siren. It doesn’t use the regular horn to do the lock chirp, it uses the alarm one (which does not come with your truck in North America)
Gave up after playing with it for a bit. I’m pretty sure it would have worked if I ordered the alarm horn. I’d try to find the connector and put a light bulb or voltmeter on it, then lock the car (after programming it). See if current goes to the horn connector. Then you know the horn will work if you order one. Wasn’t expensive ($100 or less..maybe around $50 if I remember correctly?)
Euros like the idea of brake lights flashing, but it's illegal in USA ... a thing with BMW motorcycles, too. Can't possibly look like an authorities vehicle is the reason.
Im not talking about the "chirp" sound, I mean the actual horn honking when you lock the doors. I keep reading different things. Does the X164 have the ability to make a horn sound when you lock the doors??

I've seen this before. The lights flash three times then stay lit until you release the brakes. Looks cool IMO

Alas, apparently this calls for some electronics option, because I tried enabling Flashing Stop Light and (a) it warned that some option was needed, and (b) nothing changed about my brake lights.
