As the thread title suggests i have a A4 Sline 1.9 170bhp with a hot exhaust smell and change in exhaust note . This has happened twice in the last few days after a long journey.(i regularly do long journeys and this has never happened before) The smell is like i've been gunning it and just driven through a large puddle ,the exhaust note is like the exhaust is blowing. I left it idling both times to get out and see what it could be,both times after about a minute it gives a bit of a judder and the car goes back to running normally.
Any answers would be appreciated thanks in advance DJ
