I have a 2003 A6 2.7T ... love it! ...boughth it off just off a lease with 39,000 miles on. Have had it for4 months and 10,000 miles!

Unfortunately ... i have nowrun into2 problems ....

1) when I start to brake there is a rather loud "klonk" sound from the front - sounds like it is from the front axles / brakes?

2) when i start the car up, last week a "whining" noise started - sounds very metallic and like a wheel spinning super fast... runs for about 1 minute until the car is warm... and then it stops ... ydayon my way home from work, when slowing down itcame again for a short while (2-3 seconds) and then stopped??? ...

have anyone experienced similar problems? I just had it in the shop where i got an oil change,transmission fluid changed, and rear brake pads ... this started 2 weeks after ....

any help / advise appreciated

The whining noise sounds like you have a noisy secondary air pump, it usually runs when you start it up cold and it will run sometimes on decelleration.
It shouldn't be a problem un-less the check engine light comes on.
For the brakes there are two large 21mm or 22mm bolts that hold the caliper on, if someone did a brake job and forgot to torque the bolts on of them onemight have backed out. Check it out asap!

 

The noise from the front could also be your control arms showing some signs of wear
