Morning, I've been struggling recently with my "new" 06 plate 1.9TDI and trying to get it talking with an elm 327 Bluetooth dongle (and torque pro).

The tablet and dongle have been used successfully on loads of cars more recently a Kia rio and zafira tourer.  Both show the real time telemetrics on the torque dashboard.

 

 I've found some info online that seem to point towards the ISO 9141 protocol for the ODBII port on this car, but I cant get torque to connect to the ECU.

The dongle will connect, but the ECU connection fails.  I've tried all of the various options in torque (choosing the protocol manually, fast comms on and off, 327 slow mode on and off, resetting app data etc etc).

It seems that the ECU comms knocks the whole dongle off, looses BT connection and I have to start all over again.

Never had this on any of the other cars I've tried it on.

 

I've tried pulling the battery terminal off, just incase the ECU comms is locked out, but again no joy.

 

does anyone have the specific torque setup they use for this car (its the 100HP 1.9TDI)?

or any other general suggestions?  I quite like torque itself, so if anyone has a verified working BT ODBII dongle for this specific car, I'd love to hear.

 

much appreciate (in advance) for any help.

 

 

Got a bluetooth and torque dongle working with my pd100 2007 AXR ibiza and my pd130 ASZ pre facelift ibiza.

 

This is what i have. I can look closer if you want more details. It worked straight away. Also used a odb USB cable with VCDS no problem

Is the ignition on/engine started?

 

Simplest thing first 

 

EDIT: Do you have a aftermarket or replacement radio fitted? If you do that's probably the issue! You're right the car does use the ISO9141 protocol for Diagnostic over the K-line bus. That bus is shared with the radio to allow certain OEM features to work. Aftermarkets radios don't use this functionality and some connect the K-line either to Ground or to +12V which totally stops any diagnostics (Including ELM327) from working.

Potential fix

Ok, thanks for the replies.

 

tried with engine on, and just ignored on, no joy either way.

factory radio.

 

the BT dongle fires up and connects to my tablet.  Torque connects to the adaptor but no comms to the ecu.

Do u know if that adapter is elm327 based?

I've read I need to use the KW1281 protocol which needs a WBH BT4/5 adaptor, is this right? (Not supported by elm327 chipset adaptors)

or  this one looks to support KW1281:

but £100 !

KW1281 was designed by VW and it's true the car does support it. However the car does definitely support ISO9141 (Tested working with my own ELM327) for functionality with "Generic" test devices such as the ELM327. 

 

Possible you've got a bad dongle mate?

So, the obdkey dongle was delivered today, works out of the box.

 

my elm327 dongle works in my wife's zafira tourer but not the Fabia.

bizzare.
