Siren noise on initial acceleration...

[Nige_RS4]

OK, I've been following this thread for some time, and my thinking is that it's the roof rails (assuming its an avant) - they make a siren-type of noise around 30-40mph ??

Are you serious ? I didn't see the smiley...

I agree with you Dippy. There is a big between a quiet turbine sound (normal) and a loud siren sound (not normal).

Course I'm serious, you said the noise came from the back of the car - unlikely to be the turbos then, unless it was a rear-engined S4 special [img]images/graemlins/smile.gif[/img] ??

Funny... The RS6 Avant at Hockenheim made a whistling sound at speed, but the saloon didn't. You may be onto something here.... [img]images/graemlins/sekret.gif[/img]

I didn't mention the back of the car ! Perhaps there is a misunderstanding as I said I looked round to tsee if there was a police car.
The noise was most definitely from the front. And it was noticable at very low speeds - ie, 0-20mph - as the revs built up. I was driving pretty normally and not accelerating hard or anything

OK. Thanks everyone for your responses.

I went to my local Audi dealer today and they gave me the full history for the car [img]images/graemlins/thumbs.gif[/img].
The bottom line is that the warranty will cost £765 (as previously mentioned). Because it is still in it's service schedule they will NOT need to inspect the car (saving £85). The warranty also includes Audi Roadside assist, which softens the blow a little bit.

I am now feeling a lot more settled, and am going ahead with the purchase. [img]images/graemlins/clap.gif[/img]

Thanks again to everyone

You won't regret it mate, with the warranty in place all you need to worry about is the driving.

The S4 is a truely phenominal car, and the understated looks guarantee you plenty of traffic light fun!!! [img]images/graemlins/grin.gif[/img]

I've had mine nearly a year now, and whilst I've considered tuning etc.. I don't think I'll mod it at all, I love it the way it is.

Enjoy! [img]images/graemlins/thumbs.gif[/img]

Yes, you will have to get along to a meet as well [img]images/graemlins/cool.gif[/img] . Check the Trackdays and Meets forum.


Enjoy.

I think you may be right - but only for the black roof rails.

I have the silver roof rails, and at high speed they make a screaming sound...

...or maybe it's coming from the wife in the passenger seat? [img]images/graemlins/confused.gif[/img]

My new turbos have this whistling noise from the back, but mine's a saloon - no roof rails [img]images/graemlins/laugh.gif[/img]
