Hi kind of related to my other post and probably should have posted here first.

I am looking to find out what the Octavia Mk1 and Mk2 say in the top left hand corner of this vag-com screen shot, the one below is for a golf mk5.

Its the bit that says KWP2089 that I am interested in if anyone gets the chance to have a look.

Cheers

Jim

My Octavia Mk 1 1.8T 4X4 shows Protocol KW1281 for most addresses but KWP2089 for Address 03 - ABS Brakes.

Does your device just plug into the OBD port or do you need to 'wire it in'?

I had a quick google for it but couldn't find much more than a couple of installation issues with TT owners.

Hi, it just plugs into the OBD2 port, no other wiring as all the data and power is available there.

If you google "liquid tt" you wont find much, try "liquidtt" and you should find more.

Cheers

Jim

Did you read the manual?

Ross-Tech: VCDS Tour: Open Controller

BTW: THat version of VAG-COM should not be used with PQ35 model.

Yes, not sure what you mean.

Means the version you are using is way to old to support all functions/protocols on that car.

You miss the point of what I am trying to do, I want to see what protocol is available using an older cable.

I was initially surprised that the older cable actually worked at all. Since the newer cars do support the old K-line diagnostics interface it will be easy for me to adapt my product to work on newer cars without adding a CAN interface and software stacks.

Nope, I didn't miss the point - vice versa, you missed it.

Just because a few engines still support k-line doesn't mean much. Try the TFSIs or the CR-TDIs and you will quickly notice that they don't. However, the protocol itself doesn't mean much either, if you're familiar with this you should know that one can use several different services ontop of kwp2k (and thats what my comment above was directed to)...

Point is, you better get used to the CAN problematic as well as current protocol details or your product will soon be outdated, thats my advice from a business point of view...

Currently I use 1281 to extract boost data, but getting data on the protocol has been very tricky though not impossible, it looks like you can do somthing similar on kwp2000 as shown above i.e.kwp2089, but daa on this is even more sparse the 1281.

It will be interesting to see if boost data is available via obd2 on CAN based cars.

Do you have any knowledge on this.

Just look at which PIDs are supported by the control module in generic OBD2/EOBD but I would expect the sample rate to be quite low.

I know for a fact that boost was not provided on the 1.8T which led me to use 1281 but haven't had a chance to look on any newer cars.

The market for aftermarket mods for the mk5 platform will start to develop once a reasonable number of cars get outside of their warranty period.

I plan to work on implementing a CAN version over the winter and hope that the boost info is available to minimise resarch into proprietary protocols which is very time consuming.
