Hi all just wondering what your thoughts are on the matter in hand.

After returning home from taking my car out for a little run today I noticed that one of my bosch 044 pumps has started making a really loud high ptuched whining noise when I put the ignition on to prime the pumps which is louder than usual. The car seems to drive fine and the're is no fuel pressure drop being shown on my toucan.

I currently have 2no of these pumps fitted after a swirl pot. the pumps are staged so only one is all of the time until boost kicks in. The pumps have done approx 5000miles if that so i don't want to buy a new one if it can be avoided.

Sounds perfectly normal, they are noisy buggers (I have 2 of them in my boot) if there is no drop in pressure or performance then I wouldnt worry

Maybe try DW350il might be quieter.

some bosch 044 that are having noise issues might be because it is fake. Or maybe the common prob which is your filter.
