Hi All In case anyone is looking for a cat control unit for a 348 with Motronic 2.5 I have two new and un-used ones available. I made a mistake and bought them whereas I actually needed the ones to match the Motronic 2.7. The part number is 141037 - there are two cables from it; one with a 2 pin connector and one with a 4 pin connector (the Motonic 2.7 system have one with a 6 pin connector so it is easy to check that it the right part if not sure). I'm not giving them away but I can offer them at a good discount if anyone is interested in them. Regards Mark Just send me a private message if interested. (Note that I am presently in Switzerland - so any Swiss 348 owners with the typical "slow-down lights" problem are especially welcome to contact me ;-)
