#1560 of 1807 S40 Check engine light
Jan 29, 2007 (4:19 pm)
I own a 2005 volvo s40....bought it new, two months after i bought it, the check engine light came on....here i am 2 years later and it has come on a total of 5 times. When i take it in to get fixed, ive heard everything from "check the gas cap"( which it wasnt the problem" to a "power surge" to "massive air flow". I just recently had to take it in again. One week ago today, was told it was an emission problem this time...they reset the light, and guess what...its back on today! Called them back and was told that once a month they have a specialist come in...and they would have to look at my car. Didnt relize i needed a speacialist for my car, considering i took it to a volvo dealership(where i bought it from) its served as a good comuter car, but its also been a headache! Im almost done with it completly.

I'm looking at used Volvos (among other cars), and wondering if someone can explain the real world difference between DSTC and the older STC. Am I missing out by just getting STC? I'm looking at model year 2005 and older. Seems like DSTC came out in 2007 or 2006?

What kind of gasoline are you using 87,89,93? Look what I said in a previous message:
"I have an S40 2006 2.4i and had the same problem. Solution: Start using regular (87 or 89) gasoline instead of Premium 93 I was using. Performance did not get any down penalty and the light go off until today (12000 miles). Good Luck "
Hope this help you !!!!

DSTC is a yaw control program.
It is designed to lessen the possibility of the car spinning out of control in bad weather.
It controls both the throttle and all 4 brakes.
STC is just traction control. It will lessen the chance of the front wheels breaking traction. It controls the throttle and the front brakes.
If you live in a snowy climate DSTC is a good thing to have. Otherwise, the regular STC system will do nicely.

I'd recommend getting rid of it. I have a 2001 Volvo S40 and it has been nothing but trouble. The only redeeming quality is that it is paid for. The check engine light has been on for a majority of the past 5 years. I can only take it to the Volvo dealership and they can never "fix" it for longer than a day. The o2 sensors (front and rear)have been replace a total of 9 times. I am getting rid of it this year, and going for a Honda, ready for a reliable car!

A 2001 S40 is the joint Mitsubishi/Volvo car right?

It is, if i remember correctly, a Mitsu Charisma elsewhere.

It only shares the floorpan w/ the Carisma.
Some of the lesser Euro versions also used Mitsu engines, but the US version used a Volvo engine.

really? That was a volvo engine?
Where did they get that one from? That was ... i believe ... a 2.4 4-banger, right? Was that exclusive to the S40? Seems like a pretty expensive venture to make a dedicated engine for your low-end car.
I know Mitsu makes a 2.4, so I never thought it was anything other than a Mitsu. That and it had a Mitsu turbocharger on it, didn't it?

The US S40 used a 1.9l Turbo 4. It was essentially the 2.4l 5 cyl minus 1 cyl.
The 5 cyl was part of a modular engine family, the 4, 5 and 6 cyl engines were essentially the same design.
