So, my wifes 05 XC with 75k on the clock has an issue.

Back in December I was driving the car. It was 25-30deg. I came out of the store & the car started ok, but I noticed the headlights & int light was fluctuating (diming slightly). Car ran ok, within 5 miles my CEL came on, car still ran ok. Message was check engine management syst.

Took it to my independent Volvo mech & he reset the code, but he said the code didn't say exactly what it was?

So a couple of weeks go by & one really cold 0 deg night the light comes on again & I drive it home. The lights seem to be diming again. It seems as thought the idle is low & fluctuating around 600 rpm.

I park the car in the driveway & go out a while later to start it & it's dead.
I jump it & it starts, of course the light is still on.

Back to the shop. Battery is orig; so we through a new one in & reset code.

Car runs fine for 3-4 weeks & then the light comes on again, no fluctuating lights.

Shop determines it's the air mass meter, $375 later & on our way.

A week later the light comes on again. Shop checks it out & finds a vacum hose under the manifold had a crack in it? $25 charge.

So, a month or so later (last weekend) I'm coming back from a road trip. Tooling down a long hill, 50deg, & the CEL comes on again. Stop at drive though coffee & idle is low again. Just under 1/2 tank of gas. Car is running OK otherwise, so continue 200 miles home.

Stop at shop on way home & they read the code, fuel code or something like that, supposidly not the same as the air mass code.

He says to use major brand fuel, I was using local independent + fuel. I had filled up after the light came on with Sunoco ++.

2 days later & CEL again! Shop replaces air mass & light stays off for 2 hrs; back on..

What the heck?

I have been using this shop for 10+ years & has always been good. I purch the car from him with 50k & this is the first issue I have had.

So, scheduled to go into shop this Weds.

p.s. could a voltage fluct be causing this? I haven't had any battery/charging issues, diming lights, but it's been warm.

Sorry I don't have more info on the specific codes, but it always says check engine management system.

Any thoughts woudl be apprec.

Stop throwing money at it, and bring it into a Volvo dealer.

They have a much more advance diagnostic computer specially designed for Volvos. It will tell them EXACTLY what's going on instead of just the code. In other words, the fault code is a umbrella code for many codes, the Volvo computer can read those other "smaller" codes.

^^^^Indeed^^^^

For fun, can you get a hold of a scan tool to tell us what codes are being set?
