I want to know if the mirrors are the same.

1) Will they bolt up, I want a full sized passenger mirror.

2) Is the wireing the same.

3) If not can I buy the C5 mirror and take it apart and mount half the C5 miror to the C4 arm.

4) Are the mirror caps the same, Say if I decided to get the chrome caps, will they fit my C4 mirrors, just not the passengers side obviously.

Please let me know.

 

I do not believe they are the same. Park next to a C4 and have a look. If I think of it I'll check ETKA and get part numbers.

 

Ok then, my C4 mirrors are not as pointed as the C5 mirrors, but if you could check I would greatly appreciate it. I would really hope they are the same.

 

They are not the same. Actually, some early model C5 cars have a different shape than the later years. I had an extra driver side mirror which went to audiSean, but his A6 (earlier year) did not have the same shape, even though both cars were the C5 platform.

Best of luck in your search!
