Have the 2.0t which as having issues while my wife was driving with it jerking and stalling at stoplights - she was on vac with the family so I had her put LUCAS in a couple of tanks and it got here home from Florida

BUT - now the car will start but then immediately die - the code list was long - but the easyones were misfires on all 4 so I did the coil packs and plugs - did not work

SO - Im asking for a little help - pulled the hose the throttle body and sprayed starting fluid in while starting and go results - Im thinking fuel - easiest first - fuel filter - still same results

Next fuel pumps - one in the tank - one on the back of the engine - what is the eaiest way yo check which might have failed???

, P0171(sys too lean), P0300, P0301, P0302, P0303, P0304 (misfires), P0507 (idle air), P0089 (Fuel Pressure) (sys

 

P0089 is likely the low pressure fuel pump, but no guarantees. That's the only thing that fixed mine. It didn't die out, though--just hard starts after resting and the code. There's a test that can be run by a tech with a VAG-COM. I paid the dealership to diagnose it.

 

I changed the low pressure fuel pump in the tank. Didnt fix the issue. Also the fuel filter was changed.

It still starts and immediately shuts down. I put a guage on the fule rail and turning the key to on - I get 74 psi

When you start the car it jumps up to 82/84 psi.

Does anyone know what the number should be?
