    Default VW Passat 1.4 TSI CNG 110Kw runs BAD

    Hi, i need help, can anyone of you guys check this flash?

    New spark plugs, coils, parrameters from MAS are OK... but when motor is cold starting almost 30 times... no reaction on throttle

    No DTC (i have unplugged CNG so 2 dtc stored for now) Edit: sparks are black after few km...

    149k Km i also thought it can be cracked piston, cuz these engines around 2k9 (1.4TSI with turbo and compresor) often has this fault. But it runs ok on CNG...
