Fuse F 5/1 Location? No terminal 86 S Recognized


Recommended Posts

  • Admin

If that is a fault code 25 -- No pin 86 S recognized then it would be fuse E1.

That would be the fifth row down from the top - first fuse on the left (7.5A).

If the fuse is good (when tested with a meter) then you may have a short to ground. If that is the case then look for water under the driver's seat.

Hi Loren - Thanks for the answer. I guess the Durametric software has a typo. The E1 fuse checked out okay and it looks dry, although dusty underneath the driver's seat. You are correct - the fault code is 25. What problems might a 25 fault cause? I think everything is working okay with the possible exception of occasional airbag lights. Is there a wiring schematic on the board I can examine?

Possible cause of fault:

• Pin 86 S is not detected when terminal 15 is switched on

• Fuse E1 faulty

• Short circuit to ground/open circuit in wiring between the alarm system control module and the ignition lock

• Ignition lock faulty

Hi Loren:

In step 2, I only measure 1.2V from Pin 1 to ground. Ground is taken at the door hinge or at the door lock catch. Fault 25 is intermittent. What does step 5 say?

Oops - never mind. I see step 5 is a separate attachment. What is meant by the "ignition lock?" I'm not sure what plug is being referenced.

Perhaps this is the plug being reference?

Which is terminal 86S. I change the ignition switch about a year ago. Maybe it's going bad?

P.S. Just bought another ignition switch from the Audi dealer (doesn't seem like you can enough of them around.) On the new switch Pin 86S is labeled so I should be able to trace the problem to the harness or the switch. Hopefully, it's the switch.

Thanks for your help.
