    Default 3.2 v6 - is this normal

    Hi All, my first post so please be nice

    Bought a 60k mile GSI in November with a couple of issues i'm working through - these cars are bargains!

    Can you confirm if it's normal for these cars to do this:

    1. Engine whine, almost like a quiet electronic beep or supercharger whine, at high revs.
    2. Temperature gauge, engine takes 10-15 minutes to warm up and seems to get hotter under hard acceleration, will be changing the stat today.
    3. Vibration from steering wheel from 50-70mph, seems ok at 80 (?!?!?). Suspect usual balancing issue.

    Thanks in advance guys
    Tom

    not sure about whine. a petrol engine should run about 85 no matter what. if your in town it will run hotter and fans will kick in from time to time so might be worth your while changing thermo as there a known failure issue. the vibration sounds like a wheel balance problem. try getting them balanced if this doesn't cure it i would check front wheel bearings next.

    As just said.
    The whine might be a bearing being driven from the auxillary belt or even a cambelt pully, might even be a bearing in the allternator,aircon pump.Might be a waterpump bearing too.

    Thanks all, i'll be replacing the stat if it stop raining for a few hours!

    The 'supercharger' sounds like it's built into the dashboard, and doesn't sound like a bearing to me. I'm wondering if it's the brake servo leaking but don't know enough about how they work to confirm and don't fancy taking the dash apart unless i'm 100%. Has anybody here had to get to the servo before?

    Thanks for the input
    Tom
