I own a 1990 Audi 80 and recently noticed that the D4 light is constantly blinking on the dashboard. As a novice car owner, I'm not sure what this means and how to fix it. Can someone please guide me on how to troubleshoot this issue?
ReplyThe blinking D4 light on your Audi 80 indicates a problem with the automatic transmission. First, check the transmission fluid level and make sure it's at the correct level. If not, top it up and see if the light stops blinking. If the fluid level is fine, you may need to have the transmission system diagnosed by a professional mechanic.
I had the same issue with my Audi 80 a few months ago and it turned out to be a faulty speed sensor. Get your car's computer scanned for error codes to determine the exact cause of the blinking D4 light. If it's the speed sensor, it's a relatively easy and inexpensive fix.
