Drivetrain Malfunction 247500 247600

chill8 · 05-24-2022, 04:12 AM

Hello,

I've got this set of errors pop up once or twice a week, depends how often I drive, sometimes I can drive three weeks without it, then it pops every other day.

I've been having this trouble for 3 years but otherwise car drives fine.

Since I decided I would like to keep it a lil bit longer I've got my timing chains done and now trynna figure out this error.

I've heard it could be a failing HPFP or Rail Pressure Sensor or Leaking Injector.

My average fuel consumption is around 7,2L/100km and Iam used to drive quite aggresively.

Only one thing I noticed when the car is fully warmed up and I turn it off and then turn it back on - there's no problem with starting but I can smell a little bit of fuel smell going to my cabin (when the fan turns on) which goes away in a second.. but this thing leads me to leaking injector thing.

The thing is, where should I start..

, I apperciate your feedback.

Does the car have a tune/chiptuning of any sort?

Yes, it's been tuned ever since I have it but I've got 2 control units, when I tried the original without tune It used to happen too I believe. And ofc it happens in high revs, when I floor it - sometimes, sometimes it doesn't, annoying thing.

Ok, because poor tuning often causes these codes just as well.

Might it be just a bad batch of fuel perhaps? Hopefully it's not something defective with the fuel pump(s).

Well the thing with fuel smell is rather just me being paranoid I guess coz I asked few people when turning on the car and they said they don't smell anything. Anyways I might just try to put the car to stock coz I don't have confirmed that it did the same thing with the second ecu or I can get diagnosed the pressure of Fuel Pump and injectors but I belive that if it was something fatal the car wouldn't run for 3 years and 60k kilometers with sometimes dropping these errors… And I feel like these errors are occuring when I drive for more then 30 minutes and car is fully warmed up idk about that.
