To decide what to buy for a perfect diagnostic kit for my VW Marine TDI engine.
This regards for a marine application and appreciate your advice for my further ordering of diagnostic tool, interface, software, all needed for diagnostic of my Volkswagen Marine TDI 165-5. This mainly to be used for troubleshooting, maintenance and parameters readings.

Engine type: Volkswagen Marine TDI 165-5, model year: 2008

VCDS will certainly talk to the ECU. The real question is whether the ECU requires CAN bus for communications, or whether this one is still old enough to use K-Line. Has your boat got an OBD-II style connector? If so, which pins are populated?

The Marine TDI 165-5 is a 2.5l VP-TDI (Engine Code BTW) which means our KII-USB and HEX-USB+CAN should both do the job. The diagnostic connector should be labeled accordingly, the location should be noted in the engine owners manual. Here's a scan excerpt from one... :)

Code:
Address 01: Engine
Part No: 065 906 018 G
Component: T165-5 MDC 0100SG 7285 
Coding: 00000
Shop #: WSC 00031 
Readiness: N/A

...the current version of VCDS also has TDI-Graph support for the marine engines - in case you need to adjust the injection timing. ;)

Thank you for your advice and purchase order for diagnostic connector made accordingly.

I also have a VW marine engine (V6 3.0) which I am trying to connect to my boat network with an Arduino adaptor. All of the wiring diagrams I have seen imply it uses k-line for diagnsotics but when I connect my VCDS Hex-CAN it shows it is using KWP2000 to communicate. Presumably the VCDS suggestion of KWP is actually the accurate answer.

KWP2000 is the software protocol, which actually uses the physical K-line.

Although KWP2000 can also encapsulated and transported via CAN, when VCDS shows "KWP2000", it means plain KWP2000 on K-line.

Thanks Uwe and Dave. That makes a bit more sense to me now. With the Arduino there are code libraries for both k-line and KWP2000 so I shall try the KWP variant. Interestingly there is also a CAN network on these marine engines but it seems to be solely for communicating with the multi-function tacho unit rather than diagnostics. It is however wired to pins 3 & 11 (if my memory is correct) on the OBD connector. Maybe I'll sniff them once I'm a bit more experienced with Arduino stuff.
