This winter was quite warm overall, but on March we were around 0 celsius, while typically on January and February we could have up to -20...-30C. Temperature is not a very likely cause on this case, but of course also not totally dismissed. We’ll see next winter if the fault does not show itself ea...

This fault seems to remain a mystery for now. After resetting the codes second time on April 6th, the engine fault indicator has stayed off and car works normally. I wonder if a bad batch of fuel could have caused the issue, dunno.

Thank you, I didn’t know that the codes could be translated that way. I noticed an interesting conflict on the first code. While it says ”flow too high”, but still one possible reason is blocked intake? I spoke to a local ”Volvo only” garage (not official retailer), and he said that maf failures on ...

Got the codes from a professional reader today. P010121 maf sensor circuit signal low (translation from finnish, not exact) P218821 fuel system too rich outside idle, low signal (translation from finnish, not exact) Both codes are classified being intermittent. The garage recommended replacing the m...

Normally I would use Torque and Obd Auto Doctor Pro from Creosys. But because of the current corona situation I’m 200km away from the car, and the only available reader is ”el cheapo” BLE327 which works currently only with Obd Plus, which is quite poor by the looks of it. Next step will probably be ...

Thank you for the response. I have used cheap generic elm327 readers with windows, android and ios for about 10 years, and this is the first time I encounter this kind of an issue. But a reader issue definitely would explain why there is absolutely nothing to find with google.

This response maybe comes quite a bit late, but a faulty battery could cause this kind of symptoms if voltage during startup drops too much.

Our 2008 V70 2.5T automatic has lit the engine fault symbol now twice. Both times it has happened on slow speed after several kilometers drive. After resetting the code first time it took about two weeks and maybe 200-300 km drive before appearing again. The only fault code present is P3388 and I ca...
