Can anyone tell me what the difference is between these two hood badges? They both have the same part number on the back(901 559 210 20), but the one on the right has thicker details and is more convex than the one on the left. The one on the left was never installed and was included when I bought my car. I picked up the one on the right on ebay because I thought it was a cheap price and I might just put it on my tool box or somewhere. Was there a year when they changed designs but not part numbers? Just curious. Thanks.
