2004 Volvo V40


#1

I have a V40 with 122,000 miles. About 4 to 5 years ago it started to sporadically drop subtly the RPM. It does this no matter the weather, air on or off, etc. the dealer about 2 years ago changed the idle sensor. The problem still exists today. This does not affect the performance of the car. I bought the car new, the transmission was replaced about a year and a half after I bought the car.


#2

If it’s not shaking the car, at this age and mileage, I’d forget about it. (I would, however, mention it the next time it goes in for regular maintenance.)


#3

Have you had the ECU scanned for fault codes?


#4

No,I have not. Can ask when it goes in.
