All greetings from Kiev (Ukraine)!
I have already the second Pontiac Vibe – ’07 1.8 FWD low mileage - 40625.
I can not solve the following problem - after starting the engine when the engine is cold (its temperature below 104F) if you switch the transmission to position D or R - we hear this sound: https://www.youtube.com/watch?v=moWaaoBolc8" onclick="window.open(this.href);return false;
In position P - sound is not present .
When the engine warms up 104F- the sound disappears.
Installed a new belt tensioner, belt also new.
My dealer says that this is a problem in the exhaust system. But what kind exactly?
I hope very much on your help friends!
