2012 Tiguan 2.0 TSI

Asked by Apr 17, 2017 at 05:15 AM about the 2012 Volkswagen Tiguan S

Question type: Maintenance & Repair

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?

1 Answer

Same thing happend To my 2012 cc Misfires and all that stuff replaced coil packs and plugs and I also did a carbon clean out at 70000 but right after they fixed all this stuff it happened again and I threw a code this time and ended up being a high pressure fuel pump and the fuel modulator had that replaced and no issues since hope this helps
