I recently picked up a used Audi 4000 instrument cluster and sent it to North Hollywood Speedometer, Los Angeles, to have them go over it before I have it installed in the car.
Today they called and said it says W=1580 under the trip odo reset knob. To get the gear ratios right so the speedo reads correctly, they need the corresponding number on the OEM speedo. Long story short, I no longer have the OEM speedo. The wrecking yard speedo currently in the car says W=1650, and it seemed accurate (until it failed), but I'd like to be more confident before I tell them to go ahead.
Anyone with a 4000q, please look at your speedo and let me know the corresponding number. It wouldn't hurt to know the model year of your car also. Thank you.
