i cant have the bora sport clocks in my car as its not can-bus or something like that i gave clocks part number to a guy on ukmkivs and he said no lol
I've fitted CAN clocks to non CAN cars before and they heve worked,it doesn't work on some but to say non CAN to CAN won't work is wrong (you have a better chance of success if the car is diesel).
Some non CAN cars don't pass the rev counter data properly (CAN cars pass it over the CAN system and pre-CAN cars pass it over a dedicated wire) so the rev counter doesn't work, on both petrol and diesel the airbag light needs coding out (bags still work though).
The only true way to tell is get some CAN clocks and connect them up and start the car, see if the rev counter works before the immobiliser kicks in - if it does you are good to go
Have a read of the
cluster thread on uk-mkivs
