just noticed a small noise from the injection pump at idle at the rear of the car.the car is still running perfect but i now don't trust it and i'm afraid its going to stop working at any time.i am going to remove the inspection cover tomorrow to get the part number of it,but want to be sure the one thats in it at the moment is the correct one for my model before i order a new one.also who does the cheapest bosch replacement and how much will i pay?could this noise be caused by anything else?..... mark.

I ended up buying an aftermarket one on ebay for about $70 that had the correct specs and works great. Gunar

They all make a whirring noise when running.

My CIS car (system pressure=75psi)had an S4 (sys pressure=~40psi) numbered pump on it when I got it, worked fine. IMHO, any pump that fits, and is designed for injection, will work.

thats a lot better that the €280 i was quoted from my local supplier for a replacement.
yes i know the usual noise,but this sounded like it was drawing some air as it was running.the sound wasnt constant.
thats good to know.i know thats true for most injection cars but wasnt sure for cis....thanks
