Hi we have owned our silver grey A2 1.4 tdi for nineteen years and has over 200000 miles now on the clock. I purchased it in 2004 and 10 years ago became my wifes car. its been a great workhorse over its life and we absolutely love it. we have a problem with the drivers central locking solenoid it "chatters" when the lock button is pressed. our local independent garage who has serviced the car its entire life hasn't been able to source a replacement solenoid the Audi dealer advised him they were no longer available. does anyone know where i can find one? many thanks in anticipation. Tony
