2012 Tiguan 2.0 TSI
My 2012 Tiguan 2.0 TSI w/ 68k miles on it
was running fine Wednesday afternoon but
by Thursday morning it was not running. I
would get the car to idle very tough but
once I stepped on the accelerator the car
would shut off. Fast forward to Saturday I
switch out all 4 coils and still have the
same outcome. My buddy scanned the
vehicle and multiple random misfires
occurred in cylinders 1 and 4. Also code
"01259-Fuel Pump Relay-J17 Open
Circut/Short with Ground" comes up. At
this point my car sometimes won't even
turn over. What should I do? Some have
suggested that carbon build up may be
blocking my fuel injectors. Does anyone
agree? What could possiblt cause my
engine to shut off while stepping on the
accelerator?
