    Having some problems with my 07 plate 2.0 TDI (140) sportback A3, had the car 4 months, full audi service, next one is due next month.

    I was driving along over a week ago and noticed the car was making a strange almost kind of murmuring noise at 50+ mph, it sounded like it was coming from the rear of the car, so i thought the exhaust was possibly on the way out, had the car on a ramp and there aren't any problems from that perspective, so I did a few checks under the bonnet, noticed the coolant needed topping up, so I did that, the noise still seems to there and plaguing my mind a lot so iv been keeping an eye on things daily and noticed the coolant had dropped considerably. Had it checked out today at an audi specialist, they did a pressure test that didn't come up with any visual leaks, they're saying i need to have a carbon test done to check the engine internally for leaks, i don't have the creamy oil around the cap which is a sign of the head going. I don't seem to be having any problems with temperature, it sits right at 90. Does anyone have any advice on what else it could be? Does the noise from the rear and coolant loss seem related or two different issues? Any advice would be great!

    A moderator should move this post to the A3 forum !

    Firstly, if you have only had the car 4 months - did you get a warranty ?

    Secondly, the two problems seem to me to be totally unrelated

    Finally - don't take it for a service until you know what the problems are ! An independent VAG specialist will help you. The noise from the rear may be just a wheel bearing.

    Have you noticed any leakage from the radiator or any wet carpets in the foolwells ?

    Unfortunately only a 2 month warranty, regrettably opted out of the year option because of cost but considering taking out some mechanical breakdown insurance.

    Am i right in thinking if wheel bearing is done there should be some play if i give it shake?

    No actually visual signs of leakage but il leave some cardboard under the car tonight to see if thats the case. I'll get back to you.

    Why don't you move this post to the A3 8P forum mate ?

    You will get more help from there and clearly the moderators are not watching, or if they are they are not taking any notice of my first reply !
