2018 1.4 Auto Exhaust resonance.

Post by knight-gkla » Fri Mar 22, 2019 4:15 pm

I have a second owner 2018 1.4 6 speed Auto. Great car but we live near a steep hill and going up or down, lower gears 2800-3000 rpm there's a lot of exhaust resonance. Garage couldn't find anything, is this by design or a problem?

It's not a problem as such and seems to be a feature of the exhaust design... although I doubt it was specially engineered to sound like that

OK, now My Vauxhall is up and running again I found a bit more about my vehicle. Seems the new car owner complained about "over revving" twice, soon after purchase. I believe this was exhaust resonance, only 3000rpm hardly "over revving". They probably exchanged it a couple of months later for a Ford. The previous Corsa D 4speed auto had an anti-resonance tube on the air inlet, across the top of the radiator. Any one know if this might help.

OK problem solved by Vauxhall engineer. Turned out to be a loose pipe behind the bulkhead. Everything fine now.
