DTC code 17544 hard to start after refuel

[emeth]

i have an OBD II scanner and it says DTC 17544. been battleing with this problem for months now. i ran a few tests with my car so as to detect what really went wrong ie. n75 valve, fuel injectors tests, leak test but no luck so far. kelangan ko help.
i wanna do everything i can do on my own first before finally getting it checked by the dealership aka stealership. heheh.


at eto pa! meron ako REPAIR MANUAL in pdf format para sa mga DIY owners na tulad ko. post ko dito kung meron gusto. FYI, eto ung repair manual na ginagamit ng mga stealership to fix ur beloved audi. if u have it, u have the right tools, u can pretty much fix almost every common probs with ur audi.

para sa mga gusto nga pala ng OBD II scanner, i can hook u up in case wala or mahal satin sa pinas. PM na lang.

Hello Sir,
naalala ko lang erpats ko nong nagkaron sya ng problem sa A6 nya, parang ganyan ang naging issue, nilinisan lang ang MAF sensor, then OK na... But I'm not saying na yan ang sira, just try to test some of the items listed below...goodluck

if its lean then it may be clogged injectors

Possible Solutions
Check Mass Air Flow (MAF) Sensor
Check Fuel Pressure Regulator
Check Fuel Pump
Check Intake/Exhaust System for Leaks
Check Secondary Air Injection for Leaks
Check Vacuum Lines for Leaks

check your coolant temperature sensor... when the car reaches its normal temp (90deg.) the car would experience hard starting if this sensor is bugging out... have you experienced hard starting if your engine is cold? if not then this must be your problem

*emeth, sir baka pwede po paki post ninyo yang REPAIR MANUAL ng Audi kasi malaking tulong sa mga DIY owners na tulad ko din.salamat po (APT/EPT Audi A4 2001).

Sir check nyo po yung parameter value ng oxygen sensors dun sa freeze frame data nung time na na captured nya yung faults. baka electrical interference po yan sa oxygen sensor circuit. kase po broadband yang sensor na yan eh. nag ooperate yan sa napakababang voltage.

[batangtalyer]

pinaka the best kung may oscilloscope ka jan para makita mo kung may unwanted voltage spike. yan kadalasan ang encounter ko sa mga oxygen sensor. lalu na sa upstream. kaya ginagawa ko jan, binabalutan ko ng aluminium foil yung wire ng oxy para iwas spike.

What sort of camera did you use? That is certainly a decent high quality.
