I had a code coming up (16685) cyl misfire, I was checking the coil packs on my 2002 audi a4 1.8T. I checked each individual coil for spark while engine was on, i noticed that the engine began to knock and then it died. After putting the coils back the engine will turn on and shake then die. Ive also noticed a smell of gasoline, any ideas?? My codes jumped from 3 codes to 12 after mishap. Maybe i flooeded the engine, do i just wait and trying again later?

Change all 4 coils to "R" versions and call it a day.

Just ordered them, new spark plugs too. See whats up tomorrow when it gets here.

Are those just upgraded versions of the factory Bremi coils or are we talking about Hitachi's here?

I'm not a big fan of Hitachis. I ran them for several months but at the end reinstalled the OEM "R" versions.

My car ran excessively rich with Hitachis and fuel economy was noticeably worse.

I run Bremis due to the consensus of responses I found using the search.

Installed new spark plugs and new r coils. Car starts up and runs great. The knocking noise is still present though, im aproaching 140k so im taking it to the dealership and installing the belt kit with a new water pump, maybe that will solve that. Been thinking about obtaining new knock sensors maybe that helps as well. Dealer is charging 550$ for job seems pretty good to me. Audi dealership is in Mexico though, I live right at the border . Well wish me luck.
