Hello all,

I’ve had this issue for some time now. It’s a right hand drive 2019 A5 and I get a rather disconcerting sloshing noise over my right shoulder when accelerating or braking. Of course with the petrol cap on the right side that was my immediate thought but I find it hard to believe that would slip through the design and quality checks. 
I have given the doors a good shake, nothing there. I see no liquid leakages of any note. The volume does vary over time but this could be weather or fuel tank level. 
Anyone else suffer this?

Thanks.

I've read a few posts where people have reported this and the issue was water in the sills, which has got through the bungs in the floor panel underneath the car. Might be worth checking.

this is very bad on audi for a 2019 car to have such a fault,im sure its very annoying for any owner to have this happening.

I had no idea. Thanks all for the responses and guidance. I’ll check the sills at the weekend

Didn’t even consider googling this one. School boy error. Thanks jdragon.

Any particular reason for responding to this nearer 2 year old thread James? 
I haven’t opened the link.

Just bought a 2019 A5 with sloshing in the sills, found the service bulletin and decided to share in case others had this issue. Spoke to Audi service department today and apparently there is a fix for the water ingress along with the referenced improvement for water flow in the sills… haven’t found any information on the official fix yet..
