Wanted to share...
So my mom has a VW Tiguan, basically a 4x4 GTI, with 70,000 gentle highway miles on it. Yesterday her CEL came on, then started flashing. She called me to help her figure out what to do.
So I hook up the scanner and get p300, p301, p303 ...misfires all over the place. Start investigating online. Turns out there are common issues with coilpacks going out around this age. Keep reading, turns there is also a common problem with direct injected engines where everything before the intake valves gets horribly carboned up from the PCV recirc because there is no fuel washing things down. Carbon also takes out the intake flappers.
Solutions: replace coils, decarb, hope you don't need to take stuff apart. Now where have I heard this before....
