The pump you are referring to is not the egr valve but the secondary air pump by the sounds of your description. You should be able to hear it slightly on startup as it takes the warm exhaust gasses and recirculates them into cold engine to help it heat up quicker to reduce engine wear. Your vauxhall one might be broken due to it sounding like a hoover as this is also a symptom of them wearing out. I would recommend just getting another one or grab one off ebay as they shouldnt be too expensive. Or you could strip it down and clean it and that might fix it.

I have just brought a 2000 facelift 2.3 automatic ford galaxy with 74000 miles on the clock. The gearbox was slipping very very badly so i dropped the sump and replaced the fluid (which was black). The gearbox pulls away now but only in second gear and only changes into 3rd and wont go into 4th. The gearbox still slips quite badly but at least the car now moves properly. PS the engine light is on (but the engine is perfect) Also the triptronic mode wont work. My motor factor recommenced AQ202 ATF fluid. Is this the correct fluid as i refuse to buy my fluid from the stealership due to the cost. I was also worried about the thick amount filings on the sump magnet. Does any one know how much there should be as mine was about 2-3 cms deep on the magnet. Any help would be greatly appreciated thanks
