Metallic 'clonk' sound
Discussion
Hi folks.
As I was out in my '09 DB9 Coupé today, I heard a strange metallic sound at two occasions. First, when coming to a stop after leaving the motorway, and the second time when driving around a parked car blocking my side of the road. The sound comes, I think, from the driver side of the car (LHD).
It sounds very much like a metal plate dropping against the ground. Quite nasty, to be honest. Any ideas what it might be?
Also, my left rear suspension creaks... And there's a squealing noise from the steering column.

Interesting. I have lived with what I think is that weird noise for a while, well, very occasionally I will hear it then nothing for months. Its a metallic clunk sound like something is hitting something else with a bit of grating. On mine I am sure it comes from the rhs front. I have had the car inspected by AM and an indy and both found nothing wrong. I am getting its serviced this coming week and will ask the question again. The only constant I have noticed is when the car has been parked outside overnight (rare) and it has been cold. I thought it could be suspension but if I drive it like I stole it over bumpy roads I get nothing, trackdays nothing. Then very occasionally on a cold morning, clunk, then once the car is warmed up nothing. I am starting to wonder if its something to do with the air ventilation system as it does seem to be temperature related and my car doesnt start ‘blowing’ until I have been driving for a few minutes, so could be a flap/valve stuck?
Also worth checking the metal shields/guards behind the front wheels (where the hubs attach) for any stones being stuck/wedged. Clearance is very tight behind there and I have had stones twice get caught and make a horrible scraping noise before falling away further down the road.
I will post if anything gets found re the above and it would be interesting to know how you get on. It is the only niggle with my car that I cant seem to solve.

Thank you for your reply! Annoying when one can't find what's causing it, isn't it! The point about shields behind the front wheels is interesting, there's a lot of gravel out after the winter still so I'll have to have a look. My sound came today after driving for half an hour or so.Also worth checking the metal shields/guards behind the front wheels (where the hubs attach) for any stones being stuck/wedged.

My DB9 (2012 MY) occasionally produces an unexplained metallic ‘clonk’ sound. Seems to occur after driving for a while and may be related to manoeuvring a low speed (with significant or even full lock steering input). On a couple of occasions I’ve noticed it when parked - once with engine still running, once just after engine shutdown. It sounded to me like it might be thermal expansion related. Inspection with Indy specialist did not reveal any issues.

This was it! Case closed - stones getting caught behind the guards, banging like hell when they snap loose.Gassing Station | Aston Martin | Top of Page | What's New | My Stuff
