I just bought a 96 Audi A4 and the speedo and tac don't work about every other time I start the car. Other times it works just fine. Also when they happens the climate control panel doesn't show the temp etc. I am going to look deeper into this tomorrow and have a mechanic friend see if he can run a diagnostic check but in the mean time I was wondering if anyone had similar issues and could share some wisdom. Thank you in advance.

 

I too have a 96 that had both those issues. As for the speedo it was the ignition switch that was bad. Mine also would not allow the lights and blinker to come on at times. As for the climate control, i just ignore it. I could not find any fault in the wiring to or from the control panel and discovered that when I applied pressure to the case it would work so i was assuming an intermittent short or ground issue within the panel. I didn't feel like taking that apart so like I said, I just ignore it. It seems to work most of the time regardless. Hope that helps some.

 

That does help - thank you. I will look at the ignition switch. As for the climate control I was thinking about replacing it but that will depend on how hard that might be.
