Hi guys, please help if you can. I drive a fab 2003 V8 autobiography with LPG, which Im really happy with.
Recently, I thought that I was getting some radio interference as the car has developed a quite loud random booming noise in the rear. As I usually drive with music, I thought at first that it was the speakers vibrating or the bass box had come loose in the rear. But the noise is not related to the hifi evident obviously by turning it off! The booming noise remains. It's almost as if there was a pimped escort driving behind me with a loud boom box in the back. It tends to kick in about 30-40mph, and I guess becomes slightly more noticeable at higher speeds, although not considerably noiser, just easier to hear. It comes and goes almost like the bass in music. It doesnt happen on bends, or on acceleration or deceleration....just as Im driving.
It sounds as if the bass speakers are on full but with all other sound been turned off, or a little bit like the buffeting noise you may get on a really windy day, driving at high speed.
I've had a landy man look at it, as I am off on a long trip next month but he had no idea, He took it for a drive with a mechanic who sat in the back and they knew what I was talking about but not the problem. He said wait for it to get worse and we can see then. It is definitely outside the car, and NOT inside and only when the RR is driven at reasonable speed. I also feel as if it is more easy to notice when the car is warm but this may be irrelevant.
Please offer whatever thoughts you like, as I could do with help please.
