If you don't mind a bit of wiring one of these will do the job

I've one wired to a serial port socket, but yet to get hold of a copy of carsoft to try it out with (must get around to it).

Will that work with a 38 pin socket due to prootcol. Did MB use ISO9141.?

Also you will require a multiplexer or breakout box, or probe each pin individually.

I'd be interested to see if this works.

also this one is kind a not chineese, and price is almost acceptable
but 30% for shippment to Lithuania is a sky high price...

I believe pin 15 on the 38 pin is ISO9191 K-line

Yes I'm planing to probe individually if I want other systems.

Maybe on the petrol engined cars, but 230k's experience found that to not be the case on diesels as the UK cars weren't OBDII complient before 2002, even though USA ones were from 1996.

Most importantly there was no need to have the diesel models compliant because none were shipped to the USA, unlike the petrol models.

There were of course MB diesel cars shipped to USA and they had OBDII.

Really? I didn't know that! Which diesel 210s were there?
