W447 Vito 2 to 1 passenger seat conversion airbag light

[ajsc]

Hi
I've replaced the double passenger seat with a single one in the front of my 2015 "65" registration W447 Vito.
Can anyone please advise how I should connect the cable to the seat connector, as per the photo, so that the passenger warning light goes out on the dash (as I have my MOT coming up... )
Thank you very much

Hi, I had the same issue just last months with my 2020 W447 so can tell you how I resolved for that vehicle.
I also assumed the airbag light was due to the seat sensor but the solution was much easier by reconnecting the middle seat belt recoil unit (removed but remained with the twin seat). I now store it connected but bagged under the passenger seat box mount; it does not need the red buttoned catch just the recoil unit.

Thank you so much for the response.
Please would you clarify what you mean by the recoil unit - is it the "middle" seat belt from the double passenger seat? (I removed and no longer have this, as it was integral to the double passenger seat, but may be able to source a replacement).
Please would you post some photographs of your solution?
Thank you very much

Yes, the middle seat belt as shown fitted in the first photo below( belt/buckle central and the yellow connector at base); due to its location within the seat it took about 10minutes to remove with a socket set.
The second photo shows the driver side seatbelt connected, its the same setup but for the passenger side.
The third photo is of the seatbelt I removed from the twin seat. It is connected up and stored under the passenger seat.

Sorry forgot to add that I did ask the MB dealer if the middle seat could be removed from the configuration, they did look but said it was not an option for the dealer to change.

Thank you so, so much
Is the cable in the first photograph the same one as in the third photograph connecting onto the top of the seat belt, with the brown and pink wires?
If so, I have the equivalent cable, so need to purchase a seat belt, and similarly store it under the seat.
Please would you share the part number of the seat belt with me (I can't quite make it out from the third photograph) and I will try to source one.
I am so grateful for your help

Yes, first and third photos are of the same seatbelt. I'll take another photo tomorrow morning and add it to this thread.

Sorry for the delay...

I am looking to do the same and convert my 1 + 2 vito to a 1 + 1. Did either of you have any issue with the occupancy sensor causing an SRS error when changing your seats or did you only have to connect up the original middle belt unit?

Neither of the people posting in this thread have been back to the forum since, so they're unlikely to reply.

As an aside does the passenger airbag installation (number/size/position of bags) differ between single and double passenger seat vehicles?

If so I'd be pretty cautious about this - the occupant of a single seat won't be where the passenger airbag(s) expect either person on a twin seat to be.

 

[reptilemarine]

As a follow up to my previous query, I have since converted my van to two single seats. Krystian at KDL Technologies engineered a solution for me incorporating an emulator for two occupancy sensors, a seat belt and retractor. All working perfectly and no SRS warnings or system errors on Xentry.

I get that it's possible to do this without SRS lights coming up on the cluster, but I'd still personally want to know that the number & position of passenger airbags on a van built with a twin front seat is safe for the occupant of a retrofitted single. It could be that the airbags are physically the same for both versions (which would be handy!), but I'd be slightly surprised.

Hopefully you've notified the DVLA and your insurers of the change ... did it affect the insurance?

 

[reptilemarine]

Looking at WIS all the part numbers are the same for the safety components on twin vs bench models.

Yes insurance came down actually, less people to potentially pay out when I crash. Win win! DVLA advised me it is not a notifiable modification.

 

[BTB 500]

DVLA advised me it is not a notifiable modification.

Erm ... number of seats is recorded on the V5.

 

[reptilemarine]

Yeah - 2

 

[BTB 500]

Yeah - 2

But it had 3 seats before?
