Enabling C5 Cruise Control With Lexia

Hello,

I wonder if anyone can help me. I have a 2003 C5 2.0 HDI Estate and I am trying to add cruise control.

I have bought a stalk and installed it. When checking the ECU in lexia I can see the stalk operating. I have also added the second brake switch which shows up as the redundant switch in the injection ECU, which works fine.

I enabled cruise control in the injection ECU but it does not work. I thought there might be something else to enable but I cannot find it.

Any ideas?

Thanks

Peter

Set RVV to present in injection ECU & if i remember right there is also a cruise control setting in BSI.
After you have changed the settings disconect lexia & switch the ignition off for 2 minutes to let the settings take effect (a bit like restarting your PC after installing a new program).

the car will need to be in at least 4th gear and 40mph to work, when you press the clutch it will need to be resumed

I enabled the option in the engine ecu but I cannot find anything in the BSI. Will it need this enabled to work?

Thanks

i don't think there is an option in the bsi just the injection ecu

I will try it again but I am sure it is not working. What could cause the cruise control not to work?
