Hi Chaps, I've been on the Russian website to try and obtain the part number for a new child seat sensor (W202 220cdi) as I have an intermittent SRS warning. I can't seem to find the part in the on-line catalogue. It is not listed with the other airbag components under "electrical system - subgroup 287" or with the seat components. I would appreciate any advice. I did pop into the stealer earlier and when I got back to work and looked at the quote, they had given me completely the wrong part number (a side airbag sensor) and wanted £188 Thanks in advance.
