SOURCE: what does fault code ECM - 250A long term - fuel trim:upper limit on 2004 volvo S40 mean

Sound like a problem with the MAF sensor, try replace.

Pulled codes for ECM-250A long term fuel trim upper limit, inspected and found air mass sensor failing internally, should show 4 f/s at idle and is showing 2.98 f/s at idle. Recommend replacing with new.

SOURCE: 2004 Volvo S40 Noise and check engine light. Any

warranty is 60 k or 3 years on volvos what engine is in the car if it has a 1.8 engine petrol vvti pully on it its this what causing the noise

SOURCE: i have volvo s40 2004 The engine light comes

Sounds like your dealer is feeling its way. which sensor did they say they changed and why. Do not pay for this ****, you took it to the dealer with a warning light and they say they changed something in order to attempt to cure the warning but they failed. About as much use as changing the seat covers and emptying the ash trays! When you say noise, is this a squeal, a crunch, is it continuous or is it during change gear. Does the car slip when in gear, is there vibration. Check your engine oil and transmission oil levels

Testimonial: "thanks for the help . I have checked the oil levels . The noise comes when accelarating and sounds mlike a friction noise "

Look for a pinched wire from the car being put on a rack or possibly an accident you may have had recently. If you can find no problems with the wiring or connections then it is time to see a professional transmission expert. It may just be that the transmission has an internal problem.
