Error code 144 in A6 diagnostic section

Post by falconstar16 » Thu Sep 13, 2018 1:56 am

I just purchased a 1994 940 recently and I was hoping to figure out what the A6 error code 144 means and what I need to do to repair it or solve the problem. The car has no issues with ignition so far and I thought that error code was related to the ignition.
Thank you in advance!

Hi
thank you for the reply

Where are these possible sources of fault are located? (if there is a diagram or something that would be helpful)
Also, can I easily fix these issues and what do I need to do to check or fix the sources?
Thank you!
