S40: - Cannot install isofix bracket: missing hole in chassis

kilou · Mar 21st, 2021, 05:56

Hi,

I purchased an isofix kit for the rear passenger seat of my Volvo S40 MY1997. The kit was purchased from Volvo with part nr 30618404. I had no issue installing the left bracket but struggle with the right bracket. This bracket must be attached with two bolts. The lower bolt can be attached properly but for the upper bolt, there is no matching hole in the chassis. I don't get it, the kit is supposedly compatible with my car (I checked in VADIS and there is nothing saying the brackets cannot fit a MY1997).

I'm talking about the bracket appearing on the right of tis image:

The image is upside down so the hole that has no match on the chassis is the one on the bottom of the image. On the chassis, it is supposed to sit on a metal plate behind the lower portion of the rear seat backrest. The metal plate is there but it has no hole in it...

I'm up to the point if drilling a hole myself and putting a nut behind so that I can attach this bracket properly. But this doesn't appear as the safest option...

Any idea how I should proceed? Is this kit not compatible with a MY1997 without Volvo dealers/VADIS not knowing about it?

I went ahead and drilled a hole in the metal plate behind the seat backrest and fitted the bolt with a nut:

The alu-like tape thing is just some noise insulation i fitted a few years back.

Not sure how this is supposed to be fitted. Also I don't know if the metal plate where I drilled is really meant to support that bracket. I needed a quick fix but I'll for sure need to investigate this further. For those who installed such bracket, would you have a pic of how the mounting point on the chassis look like?
