Retrofit electric tailgate

Post by ezejp »

Hi, I am doing research to retrofit the electric tailgate in my C5AC, I got some of the parts, and in the meanwhile before buying the tailgate struts that are the most expensive, wanted to know if someone has done something similar here? I see that parts are similar as in C4 Picasso b78, 3008 and sure some more.
I am missing the wiring diagram, so working on get that too. As I think it can be a good start, to see if I can connect the electric module to bsi, and check if functions respond (with a voltmeter)

Thanks for your time and reading!

I really wouldn't bother to be honest - these are factory fitted options only, so have a completely different tailgate wiring harness and are completely different to the C4 Picasso B78. Some trim elements are different too. Further, there are other issues to consider like the hands free access / starting as the fobs are also different according to options.

Thanks, it's already started, since I know there will be some incompatibilities, I know that it may not fully work. I mean, if for example hands free doesn't work it won't be a problem. I am doing this to learn on different bsi configurations, and hoping to solve issues I may found.
If after several tries, nothing work, well i will be at the same starting point, without electric tailgate.

One question that may be someone can answer, is there any suscription in service.citroen web page to access wiring diagrams? or the suscriptions are only to see parts?

thanks

Wiring diagrams are chargeable and separate to parts.

Thanks, and the URL to access to wiring is the same as parts? do you know if a VIN is needed or it can show wiring depending the car/model selected?

You'll have to find that out for yourself I'm afraid. I know diagnostic procedures requires purchase of tokens and that is 1 token for one vehicle for 1 week or 2 tokens for 1 vehicle for 2 weeks or 2 vehicles for one week and yes VIN is required.

I can't advise about the electrical diagrams - but I know that many have paid for access, but have not been able to get access and support has not responded.... so you take a chance here.

It is my understanding that the diagrams should be accessed by URL.

You dont need a VIN to look up wiring diagrams on servicebox. You can manually select them with just vehicle details.

I only mentioned that in relation to diagnostic procedures, for which you do.

With a live connection you can access the SEDRE wiring diagrams via Diagbox however the normal way would be via servicebox. I would say you just need an hours normal technical subscription which should let you look up tech procedures and wiring diagrams. Once in servicebox you just select this menu & it will take you to SEDRE for wiring diagrams. If you have input the VIN it will pre fill most of the info for you in most cases. If you go in without VIN it will just let you select the vehicle manually.
I suspect if you went in using diagbox you would still need a separate technical subscription anyway as well as the diagbox token.
