Hello all
im new to this forum and I guess the cliche is “sorry to if this has been asked before”
but here it goes,
A6 2.7 tdi 57 plate great condition all round car, only bought as a second car,
only had it 3 weeks and suddenly I have while driving esp fault light on parking break malfunction
the sound of locking and unlocking of central locking
constantly, and when accelerating on hills 3rd 4th
gear slight judder , rear window wiper not working
i have replaced the battery and alternator working fine
Other than that polishes up nice :-))
any help advice be appreciated

If you bought it from a dealer my advice would be to get it back to them asap as you have a month returns warranty. Or get a diagnostic check carried out
