Answers:
I have a '98 Opel Vectra ,and I notice lately that its leaking water in the interior...?
It sounds like engine "knock" or "pre-ignition" as it will only occur under load. Try switching to a high octane fuel and see if it goes away. You may have to get the timing checked as well, too much advance will also cause this.... good luck!Where and how did Volkswagens originate?
Check the water pumpWhy does my ford focus engine light keep coming on then off then on then off etc?
i own a repair shop ,and you need to check the coolant level in it,it sounds like air has gotten in to the system on it,that will cause this very same sound you said it makes,and the air bubble will have to gotten out of it,its probably nothing serious,but check everything as far as the fluids go,and make sure its full,the sound your hearing probably is air trapped right now in the heater core on it,it sounds kind of weird when they do this,but it probably not a serious thing right now,but have it all checked just to be sure,good luck i hope this helps.check the timing or else your not advancing under load
