I bought a 2005 A6 2.4 liter about a month ago,and it serves me very well. I've owned a 1998 A4 2.4 and a 1992 80 2.8E before.

Here are my questions/problems:
1. Last week the braking error lights have started turning on. I get a warning "ESP fault, CHECK OWNER'S MANUAL" and "PARKING BRAKE MALFUNCTION" from time to time as I'm driving. After some times it gets back normal, and also with these lights on I can normaly activate the parking brake. What could be the reasons for this?? Braking fluid? Sensors?

2. Today when I tried to pull my A6 in neutral, it didn't go over 4000 RPM. Just stopped there. Is this a limit? When moving, there is no problem with this.

3. Looking for an option to play MP3 files. I heard somewhere that an upgrade to the MMI (I have MMI Basic Plus) can allow the CD player to read MP3 files. Another option is Dension. I also tried with FM transmitter and Bluetooth streaming, but it's very bad quality. What do you recommend?

I think there are some questions left that I forgot and I'll put them down when I remember them.

Thank you very much for any help!

Regards,
masters
