The Passat W8 started to misfire badly yesterday. I was a bit worried but I decided to start with the spark plugs. At 57K miles since the last change, they are a bit overdue (these should be changed every 40K miles). I have always have the dealer do it but I decided to do them myself this time. The process is actually pretty simple. You can find a well illustrated write-up @ the Passat World Forums. However, here are a few pictures of my car for comparison:
The good news is that the misfire is gone and our daily driver is back on the road!
