On a 2003 w203 C200 Kompressor the Check Engine Light came on.

I have a T30 with Xentry and tried it for the first time with a Memoscan multiplexer. On connection both the lights came on - but were not flashing (which i understand can indicate data).

The Xentry system started the communication layer (?) but then failed to communicate -saying it was not finding 12 volts on circuits 30 and 31 ??

So I am guessing the fuses have gone- but on checking the fuse panel on the side of the dashboard it said fuse 62 - but that feeds the dipped headlights as well - which are working.

Can anyone help on other fuses please

Have you ever used the MUX setup you have before?

I would get a friend with a generic OBD2 tool to scan the light for you and see if he can read it to debug your setup.

If his tool can't read the CEL then you have an internal prob.

I have a T30 with the STAR C3 multiplexer, works like a champ.
