Plugging in fault code reader on W202 C220

[420SE]

Just had a look around the engine bay this morning and in the top right corner, there is a cap which comes off, revealing a plu like thingy

1. Is this the only location to plug in a diagnostic tool, or will there be something inside the car too?

2. I'm going to order a U581 code reader later today, would I be right in thinking that I need one of the plug adaptors shown below?

U581
Car Code Reader / Scanner OBD2 / EOBD CAN U581 2010 DTC on eBay (end time 24-Mar-10 11:21:47 GMT)

Adaptor
16pin to 38Pin Mercedes Benz Adaptor CABLE 38 Pin obd2 on eBay (end time 17-Jan-10 21:57:52 GMT)

UPDATE: bugger.

Just spoke with Mike from OBD2 | CARSOFT 8.2 | Car Code Readers | EOBD | OBD | Professional vehicle diagnostics MaxiDas DS708 and the Launch X431 from Talk To My Car who said that neither of the machines I have picked out above will work as diesels only became OBDII compliant from 2004 onwards.

So that's my plan shot down then.

Very kind of you, thank you.

I spoke to the company mentioned above, chap called Mike runs it, he said that if my moel was a petrol C class, it would have been fine, but apparently because it is a diesel, it won't be able to communicate with the device.
