Just acquired a very nice E200 Elegance and after a check around and a good drive, can find just small problem/****le...... When I click unlock with the remote all the 4 door lock buttons come up and doors open immediately - except the driver door which appears to take about another 30 seconds to unlock. Hope one of our forum experts might be able to advice if this is as it should be. Thanks and the best of everything to forum members for 2011.
