Hi
I was driving home this morning and started to feel the road was uneven/ridged, though I doubted it was, especially when it went on for some time. Thinking it might be a tyre issue, I pulled off the road and could immediately hear this fairly loud regular pffffting ?? noise, which sounded like a hole in the exhaust but I couldn't pin-point where it was coming from.
Having decided to go to the exhaust place, I set off again and the car drove perfectly, so instead I came back home and on arrival, couldn't hear anything out of the ordinary.
Not happy, I took off again and after a few miles, stopped for a listen underneath and this time there was a typical exhaust blow noise, though not so loud as the first time. So off I go to the exhaust place. Up it goes onto the ramp. Nothing. He says there is no leak and all the mountings are sound so off I go again. Stop on the way home and can definitely hear it blowing, though driving OK. Get back home, nothing. Can't hear anything out of the ordinary.
I'm wondering if something - cat- has broken up inside and there's bits shifting around ? Do I just wait until it get worse. I'm guessing an emissions test might show up something ? What is the best course of action?
