Hi all,
Ever since I bought my car a few months ago (2012 opel insignia select with 65000km) I noticed an odd humming noise (regardless of rpm the sound does not change). It was used for city driving before I got it and when I first picked it up this humming noise would happen quite often.
Now that I have had it a while though driving it daily (fairly rural driving so a consistent speed for 20-30 minutes at a time) it has decreased in frequency.
I have tried to take a video of the noise but it did not work out. So my question is does anybody have or have you had this humming sound in your car?
What do you think it could be a water pump? The DPF?
Thanks for your help.
