Radio failed to work and sometimes came on by itself. Went to dealership and they replaced radio under warranty.
A year later, the car wouldn't start but lights would work and radio as well. Took to dealer and they repaired electric sensor.
A year or so later, the battery went dead. Went to dealer and they replaced it under warranty.
A year later, the battery went dead, car out of warranty. Bought new battery. OK for a while.
Then months later, wouldn't start. Took to good mechanic and he diagnosed it. First tested security locks and left locked at all times unused. Drained battery still.
Then, pulled out the radio and for last 6 months, there have been NO PROBLEMS without THE RADIO. Inspected radio, there was a sticker - the dealership replaced my new radio during the first year with a FACTORY REFURBISHED radio!!!
Now, I am looking to get a new radio, but local audio installers can't find VW harness and can't help me. The dealer couldn't provide harness either, but offered to SELL ME A RADIO! They are nuts!
