Hi Lindsay,
Unfortunately it only worked as well as the eBay lead! I could only connect to the CR engine ECU with it.
Pin outs seem very poorly distributed and do not match my Autel Benz CV-14 adaptor. The only pins correctly connected seem to be the Live and grounds and one of the K-lines.
Here is how the pin-outs compare:
Sprinter DLC Function Autel eBay Ali-Express
1 Ground KL31 4,5 4 5
2 Ign On KL15 8 N/C N/C
3 Live KL30 16 16 16
4 Immobiliser 12 15 3
5 Engine rpm 11 N/C 2
6 Central Lock 3 N/C 6
7 Alarm 1 N/C 7
8 SRS/Airbag 6 N/C 8
9 Auto G/Box 15 N/C 9
10 Speed Control 2 N/C 10
11 Add'tl Heating 13 N/C 11
12 IC 7 N/C 12
13 ABS 9 N/C 13
14 CR CDI 14 7 14
When I get time I will try re-soldering the Ali-Express cable to match the Autel adaptor.
At least this is a cheap source of the 14 pin MB plug!
Keith.
