2006 S40 (not turbo)<p>in the engine compartment, its on the drivers side between the battery an the bumper. It has a polished metal top that has a hose coming out which splits into 2 hoses, one going into the valve cover and the other into the firewall. And it says "Pumpe PU28" on it. If you touch the top of it or the hose coming out of it youll feel the sound vibration...<p>A couple days ago this pump? started making this weird high pitched noise. Its really loud and makes the noise while the car is on and continues to make the noise for about a minute or two after the car turns off, then it just abruptly stops, it doesnt wind down or anything. What is this and is that noise normal?? We've had the car since it was new with no issues. And the car appears to be driving normally still. It has never done this before<p>If you know what it is please help me out. Ill post a generic picture if i didnt describe it well enough. Please help <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0">

Re: Please name this part. What is it? (poprocks)

I wanna say its a pump related to the vacuum system in the car. Mine was replaced when it was making the crazy "ERRRRRRRRRRRHHRHRHHRHHR" noise.<p>lol.

I'd search the parts microfiche on any one of numerous sites. Click around, look at some engine diagrams, and you'll stumble across it relatively quickly.

Re: (EricV)

I've been told that it is the fuel pump? <p>Anyway, mine started to make a lot of noise and get really hot! Car was using a lot of gas. Took it to the dealer who though it should be moved. Looked over the car and found out that the stuff that needed moving already had to be moved. <br>They told me that I could easily run the car and if it got to hot (which was unlikely) a fuse would burn and nothing would happen. <p>After one month the car fixed it self.

Re: (volvosince16)

As already said above it's definately the vacuum pump and should be able to read the part # directly off the unit unless the sticker is missing or badly worn in which case just ask the dealer to look it up and give you an estimate for parts only while your at it.

Re:

Its the vacuum pump and usually when they are making that noise they will require replacement. Any dealership should be able to find a part number for you and order a replacement part.<p>Volvos use vacuum pumps to make sure that the brake booster has an ample supply in order to always have proper brake operation. First i would check to verify there is no leak thus why the pump stays on all the time or if the pump itself is faulty.

Re: Re: (ForceFed Motorsports)

To add to what Kyle said, My pump failed just before the warranty expired. The rotor inside the pump locked up and blew the fuse which also powers the O2 sensor which triggers the Check Engine light. <br> My dealer replaced the pump but didn't fix the vacuum leak, the new pump ran for several minutes after I would shut the car off. This lasted for a couple months and just as mysteriously as the problem came the problem left about a year ago.
