164, 24v 1993, ECU error code 31

Post by 164Carlos »

Hi all! Hope someone can help me!

Get this errocode from MES;

31, unknown / no power supply

Same code in wilcos software.

I delete it, but it reappear at once.

Anyone have any idea what it could be?

The car seems to run ok.

Any advice appreciated :)
