KI.15 supply (control unit)

The offending culprit is the pressure sensor switch and has been left unplugged until the new one arrives.

At least the fuse has stopped blowing and everything else is back to normal.

hi there, my A6 02 plate, is doing the same thing, are there any picture references to the details you have described? (electrics are not my strong point)..

Hm OK, thanks.

Fuse 5 blows instantly ignition switched on - I'll have a prod about later, but do you think maybe faulty ignition or just a bad connection/wire somewhere?

Im in same boat. Stumped. I have gone over tons of wires n spots. Driving me nuts. Also hazards n door locks go off 10x like crazy when super cold out.

Can you give me any ideas to how you resolved your issue. I'm busting my brain and patience dealing wit this fuse. I've gotten it to not blow... but shortly into driving it then again blows. I've had a number of other crazy things happen to me since this issue.

This fuse became a issue after engine replacement by a friend of mine I was not there to help him much but I feel maybe he cause a short to ground n have chkd all front end wires besides the one to a.c. compressor valve on the compressor n oil temp sensor if my 2000 2.7t has one on the upper oil pan which IDK.

I've checked everything simple... I'm dieing with no heat n a.c.

Thanks

Is this the switch that screws into the air-con piping between below the O/S headlight and air-con rad? G65?

If so mine was showing as being the fault on my AC with VCDS but it hasn't cured it by changing it, wasn't blowing the fuse though.
