the led display has malfunctioned, all its showing is lines across the display. Ive checked the fuses and disconnected the battery. Banged on the dash, to no avail any solutions?

I have a 90s4 and it did the same thing one time and went away. I think my battery may have been drained at the time.

The lines come on mine when the battery is newly connected. Then eventually change to read out within a second or so. So its something in the boot up.

Charge the battery and check the fuses

Try raising and lowering the pod while the car is running. My LED was flashing solid until I did this, then "voila!", it came right back on.

This is after I had:

• checked the hot post
• cleaned the grounds, including the pod grounds
• replaced all fuses
• sprayed contact cleaner on the central panel while fuses were out
• removed the instrument panel and cleaned the four connectors and the panel contacts

All this was performed with the battery disconnected, BTW. I have a recent thread on this, including loss of fuel, speedo, and tach at: https://rennlist.com/forums/928-foru...or-latest.html
