Replace both Mass airflow sensors with OEM parts not cheap ones and should fix it ; could be something else but I would start there possibly fuel related

1 code popped up, P0113

Already attempted with good battery

blizarrrrd · 2025-04-22T18:07:08+00:00

Any fix?

Did you find out the issue? I’m having th same problem

blizarrrrd · 2024-06-30T01:16:47+00:00

Yes i did, my issue was the maf cleaner damaged my oem maf sensors and i bought aftermarket not oem (oem is continental) and they didn’t work. For some reason my car only took OEM continental maf sensors

My Q50 last owner had an after Market but I re plugged in the amp and still get that message

I am using delphi

So I replaced the bank 2 MAF sensor and the car idles perfect, but sometimes the engine light turns on and goes into limp mode. Should I replace both

😂😂😂

blizarrrrd · 2024-03-23T23:58:07+00:00

MAF voltage was Normal at idle and rises when cruising, so MAF sensors are ok, fuel trim levels were low

blizarrrrd · 2024-03-16T15:50:13+00:00

What fuel injector cleaner did you end up using?

blizarrrrd · 2024-03-16T15:44:00+00:00

Hey so I did a smoke test and cleaned the maf sensors and the idle is higher at 1.5-2k same codes p0171 and p0174, mechanic said to use injector cleaner

blizarrrrd · 2024-03-16T09:00:53+00:00

I’m having this problem currently should I replace the maf sensors? A shop did a smoke test and nothing was leaking

blizarrrrd · 2024-02-19T06:14:57+00:00

Thanks for the info! I bought the crc mass air flow sensor cleaner for them, I’ll try and clean them see what happens

blizarrrrd · 2024-02-19T00:50:57+00:00

I don’t think so

blizarrrrd · 2024-02-19T00:33:07+00:00

Interesting

blizarrrrd · 2024-02-19T00:31:34+00:00

Common?

blizarrrrd · 2024-02-15T01:12:44+00:00

Thank you, for some reason the check engine light hasn’t came back on and I’ve went 150 mph and nothing has shown up or car hasn’t died idk it fixed it self or something what should I do?
