Just got myself hooked up with this nifty app, but I'm disappointed to find it can't read things like EGT, EGR setting, and DPF temps. Can these be accessed by manually inputting the relevent pid or are the only readable with vcds etc? I've seen Passat owners in the states get access, but not sure that's on a PD170. Is there a list of PID's anyone knows of?

Cheerz.

After some digging, it seems nobody knows. Bit hacked off as I really wanted this to keep an eye on exhaust temps and when regens are happening. Buyer beware!

You need one of these if you want to get the full range of sensors

Thanks for that. Might have to save for a while. You used these?

Yes, but got an older model.

Takes a bit of setting up but all works great now.

Really? In what way?

I am not very good at explaining but you need to create a text file that labels all the measuring blocks. Visit the torque forum there is loads of info on there.

OBD2 PID scan or at least decoding the supperted PIDs is not a rocket science.

Everything is here:

https://en.wikipedia.org/wiki/OBD-II_PIDs

 

Mode 01 0x00, 0x20, 0x40... are the coded PIDs, where the supported PIDs are encoded.

Torque is capable to read this via extended PIDs.

 

Example for 0x00 PID:

Since the response is 4 byte long, you have to set 4 extended PID.

Most significant byte: A (PIDs from x01 to x20)

Mode and PID: 0100

Long name: PIDs_Mode1_01_20 (or whatever you want)

Short name: PID0120A (or whatever you want)

Min value: 0 (Torque will change it 0.0, but don't bother)

Max value: 255 (Torque will change it 255.0, but don't bother)

Scale: x1 (default)

Equation: A

(leave the rest as is)

 

The result will be decimal, so you have to convert it to binary/hex. See: binhex.jpg

 

The same extended PID has to be created, the difference is, that the Equation will be B, C and D for the 0x00 PID.

For 0x20, 0x40, ... PIDs the method is the same.

When you have all the supported PIDs, the most simple way to decode them is this program:

https://www.outilsobdfacile.com/obd-mode-pid.php

using the PID decoder.

 

Here is my exported csv, if you don't want to bother editing the extended PIDs:  supportedPIDs.csv

I've also scanned Mode6 PIDs, the result is this in Torque: Mode1_Mode6_PIDs.png

And the decoded result: OBD_Mode1.jpg, OBD_Mode6_CAN.jpg

 

Finally if you want to see all your supported PIDs in Torque, you only have to add them one-by-one or via csv (don't forget to equations!, for details see the Wikipedia).
