Hello there,
Some time ago I changed the diff in my 2003 Series 3 NB from the stock 3:6 ratio to a 4:1.
This achieved in giving me a bit of extra pull I needed when going up steep grades etc.
The problem is, now the speedo reads at 9% out of whack, i.e: 121 kph is actually 110 kph, 110 kph is actually 100 kph etc.
I've been told that I need to get a (RED) cog for the cable that runs into the side of the gearbox, to bring everything back to where it is meant to be. So I was wondering if any of you may have one of these cogs laying around that you are willing to part with?
Thanks for any help that may come my way.
Cheers, Wayne.
