I need some help on my AUdi A4 1.8T. right now idling very roughly and when
i used my VAG it states that 16687 cylinder #3 misfire detected would this
mean that I need a spark plug? sorry to be asking such stupid questions.

It is almost sure that you have a failed coil on #3. They can be sourced
on line for $23 - $30 or dealer for a bit more. Just unplug the old one
and replace with the new one. You probably have 'L' series CPs. you can
check by looking ant the part number on the CP at the last character.
The 'L' series all seemed to fail. Either replace this one with the
current 'R' series CP and carry two spares in the trunk ro do yourself a
favor and replace all four now as the others will fail soon after the
first one.

Do NOT drive the car until you get this corrected even to go get the CP.
You will likely burn out your catalytic converter for $1,000 plus labor.

well i had to take it to the audi dealer by my place and i told them all
about the code so they tried testing the spark plugs and also the coil and
it was still bad so after that they tested the powersurge? something like
that but anyway it ended up causing me 740.00 ouch...
