The check engine light was on a few months ago. When I took to my Volvo mechanic (not dealer), he said there was a leak from a bad gas cap. I replaced the gas cap a few weeks ago, but the CEL is still on. Should I have the codes read AGAIN by my mechanic? Or will it take a while for the codes to res...

Mike -

What type of bulb is used on that panel? I have to get in to replace the ones in my '04 V40 as well. Would love to know how you fare.

Best,
Daniel

Thanks for responding.

Prior to posting, I called around to the AutoZones here in the San Francisco Bay Area and learned that they no longer offer that service. They referred me to Midas, who charges $135.

Hi - 2 questions about warning lights on my 2004 V40 with 71k miles: 1) The 'Check Engine' light comes on intermittently - about 30% of the time. I called my local Volvo guy and he said it costs $90 to have the car hooked up to the computer to check the codes. Is this fair price? Is this something I...

Update: Turns out the constant idle speed motor was going kaput. Had that replaced - for $400 parts/labor - and all is good now...

This morning I was able to start my car - the engine turned over normally - but it immediately stalled. The car just won't idle after it starts.

I have just one fob on the keychain. In fact, we're taking the car in next week to have a new second fob programmed for the car.

What do you think?

Hi - I'm noticing that occasionally the immobilizer light will come on the dash when I first start the car (04 V40 with 63k miles), but I'm still able to shift and drive the car. Each time I restart the car after the first instance, the light does not come on again. (This i the light with an X acros...

The car has 63,000 miles on it - the factory warranty was kaput at 50,000. The transmission fluid was the first thing I thought of, but I don't have all of the service records, unfortunately. An "expert" on another site said the shifting behavior is normal for these Volvos. Nevertheless, I...

I just brought home an automatic 2004 V40 with Turbo and I found that when I'm driving block-to-block in the city at between 5-30mph, there's a delay in changing gears, which is a little jerky. If I ease up just a little bit on the gas, the car shifts appropriately. I've never owned/driven a turbo b...
