Retrofit cruise control
 

So I've finally got round to connecting all the wires on my retrofit cdti without factory loom,I'm confident I've got all the connections ok and the brake and clutch switches are good but the cruuse light on the ipk stays permanently on when the engine is started and the cruise switch only flashes green briefly when pressed someting is wrong somewhere just wondering if anyone else has had this ,can the cruise ecu fail ?

I have not encountered a faulty diesel cruise ecu to date, I would carefully recheck your wiring is correct ;)

The wiring diagram I've attached for you :cool:

Best of luck

Brian :D

Sounds like it needs t4 programming?

When I fitted mine on my diesel it worked ok the only thing I needed a t4 was to enable the resume function every thing else was fine Brian slighted this for me

Thanks for the info Brian, I’m going to double check the wiring bit worried about connecting it up again though in case it causes problems with the main ecu

sounds to me like you may have 2 wires the wrong way around. I'm assuming you used my how to guide for retroffiting cruise control here:https://www.the75andztclub.co.uk/for...d.php?t=228668

Have another thorough check of all the cable connections to ensure they're all connected to the right places. Having two cables the wrong way around can easily be missed. I'd start at the cruise master switch.

Yes i followed your excellent guide but have now come to accept I've wired it wrong the light comes on even with the switch disconected,I'm gonna take a breather and try again thanks for the info folks
