OBD1 cable

Does anyone know if this OBD1A Diagnostics - ISO9141 / KWP2000 PROTOCOL cable will work on a 1998 Xantia 1.8i 16v and or 1999 Saxo 1.0 ?

Their list shows a Xantia and Saxo but they could not confirm any customer using it on my particular cars.

Thanks

I very much doubt this will work in any meaningful way. Citroens (and Peugeots) of this age used very much their own diagnostic protocols and despite MK2 Xantias having a diagnostic socket that looked suspiciously like an OBDII one, they were not OBDII (or ODBI) compatible.

Bottom line si that generally diagnostics can only be performed by a Citroen Lexia, Proxia or ELIT machine or one of the specially designed ones like the Sykes Pickavant ACR4.

Sorry to be the bearer of bad news

Actually, it's better than that - NOT.

OBD scanners can give totally false or half-cocked interpretations of the PSA coding. I've seen this with my own eyes, in a little test I tried on the Xantia using a fancy tool in generic mode.

The Chinese "Fauxia" or "Peugeot Pranet" software with dongle, is the OP's safest bet for cheap DIY diagnosis.
