WEIRD NOISE S70

Hello,

Recently my 98 S70 Glt starts making a noise like a turbine driven something 30 seconds after starting. It continues for a minute then dies down. It never made this noise before. Does something need a lube job, or is something on its way out? I don't want to be taken for a ride with the dealer mechanic.
Thanks,
Trish

    That would be your air pump..Mine has started the same thing..(noisy)
    the information I have gotten is to drill a hole on the bottom side to allow
    the water to escape. I havent looked at it yet and I'm not sure where to dril
    the hole but I am told that it is obvious when you look at it.
    I have a 98 w/turbo.

      Thanks.

      The part seems a bit pricy ($325.00) for the pump. A fan for $325? What gives?
      When the pump fails, will the car not run/start? Whats the deal with this pump?

      Thanks again,

      T

        The secondary air intake pump is there simply to feed the exhaust sys air and
        get the cat converter up to temp quickly (liking blowing on a campfire to get it going).. this reduces emmisions as the cat is hot shortly after start up.
        If the air pump dies it is not a driveability issue. However, if you have to do the smog check in your area your car will not pass as the check engine light will be on. I replace the air pump on my 98 jetta.. not only was it a PITA to get to it cost $400.00.
        I got it in just before my tags expired and then the CIL came on again. Seems a associated valve was faulty also ( the pump on this car was FULL of water and that
        is probably what killed the check valve..) Anyway this was the last day on my tags so I had to do something.. I cleared the codes.. unhooked the battery an then hooked it back up.. clearing anything in the computer's memory.. and drove straight to the emmisions station. As I had cleared the memory they had to go back to the old way of sniffing the tail pipe emmisions instead of useing the car's OBD II diagnostics port.It passed.. I got my tags..:-)
        The only good thing here is that the air pump on the s-70 is pretty easy to get
        to as it is in the wheel well as i remember and not under the intake manifold as it is on my Jetta.
        If yours is making noise it may just need the drain hole drilled to get the
        water out.. or it could be the check valve is acting up which is the cheapest fix!

        Good luck and dont worry about driving the car under this condition..

          Thank you so much for the great info.
          Yesterday the pump only came on for 20 secs or so. Maybe becauseit was a bit warmer today. I will get the codes cleared as it is due for a test soon. I hear it's a good idea to drive the car and have it already warmed for the sniffer test instead of it being cold when the exhaust is full of cr#p.

            Well if you live 4 - 5 miles away from the station I would think it
            would plenty warm enough...
            My S-70 is up to temp within a couple miles from home.
            Keep in mind that clearing the ECL will only turn the light off for
            a while.
            You need to
            1) clear the ECL
            2) disconnect the ground strap on your battery (make sure you have your
            cd player's activation code still)
            3) reconnect the battery and drive over to the station.

            It takes a hundred plus miles for the on board diagnostics to rebuild
            the history data which was dumped when you disconnected the battery. The
            sniffer station can/will read the historical data also so it has to be cleared.
            This worked for me. :-) Good luck! also post back if all went well.
