Just bought a 2003 XC70 D5, some small issues

DirtyC70 · Mar 30th, 2024, 18:44

I have SRS light on, no horn and no multifunction controls. Clockspring?

I also have the clock on the speedo infinitely scrolling, and the trip and clock toggles don't seem to work. DIM repair needed? Is there anyone on the forum offering this service?

The car is also hunting at idle. You can't see it on the rev counter but you can definitely hear and feel a surge every few seconds. Not sure where to begin with this one. It drives fine.

TIA

First off, Vida code read. Clear existing codes and then re-read.

I have a copy of VIDA arriving next week some time, I was hoping I could make a little progress without it for the time being.

Suspect vacuum leak for the hunting idle, taking oil filler cap off confirmed as much. Traced leak from hose running under car to actuator? (engine mount?...). Blanked off and now I have a lot more boost but still some hunting at idle.

if / when it comes to electrical repairs these are the well recognised experts down south, you'd probably want to post it to them from where you are I suppose

but agree with above always codes first and go from there anything else is just a wild stab in the dark

Clockspring replaced, reconditioned DIM replaced. No more codes.

Hunting at idle I suspect may be fuel regulator. Injectors and Pump confirmed good, new OEM fuel filter, no vacuum leaks. Fuel rail pressure in VIDA is spiking. Any way to test the regulator?
