Reading Error Codes

[pgs49sullit]

Hi - fresh meat here, just joined the forum. My wife has a 1999 SLK 200 Kompressor and I have a W202 C200 myself.

I'd quite like to learn how to read the error codes - particularly since the engine warning light came on the SLK this afternoon. I have the laptop, I expect I'll need some form of bridge cable and some software - what's my chances do you think?

Is it something that is covered in these forums or am I transgressing rules by asking?

Any/All help greatly appreciated.

Peter

Both of your cars will have the 38 pin socket I think so something that can read from those ports
