Got my 2007 2.0t Vectra with 40K miles on the clock and it is a nice ride, but I noticed some strange noise, only when engine is warm.
I drove over 60 miles every day and when I stop and leave the car in neutral I can hear tapping/ticking noise from the right side of engine (near the tyre) if I look the car from the front. If I go in a car and press clutch or just slightly press on gas pedal, noise disappears and then come back again when idling.
Pressing clutch several times and noise is gone for some time...it's like something gets in resonance or two small steel materials will tapping
BTW: I noticed that service fill oil over the maximum indicator...is this somehow related?
Is this something to worry about?
