Hello chaps,
I am very sorry to start an introduction with a problem but this has got me quite worried.
So this morning, I start my car and, on acceleration, hear this rhythmic 'thump, thump' of a sound like I have a flat tyre. I only hear it at low speeds and disappears (becomes faint) at high speed. Any ideas what this might be? Checked my tyres and it wasn't flat or anything. Really annoying and has got me quite worried. It's a 2006 A3 Petrol Automatic but in pristine condition as it was hardly used with only 16000 miles on it.
Any help appreciated chaps.
Jay
