Error code...?

Hi All, I have exactly the same car and exactly the same error codes. In addition to the error code, in my car I experience the behaviour described here: https://www.volvoforums.org.uk/showthread.php? t=168829 Anyone has any idea on what the problem could be? Thank you very much in advance.

Bazbart giv us this answer: "Hi, The car is long gone now. I got the pedal changed but the garage never updated the software initially. There was no change. I eventually brought it to a Volvo garage in another town and explained that the pedal was changed. They updated the software and they also updated the Volvo ecu software and after doing that it drove perfectly. I hope that helps." Maybe that can help?

Please give feedback on how it went if you try this! :)

Hello, yes I saw that answer from the forum I linked. Nonetheless, that refers to code P1577 only and not to the "combination" of P1577 and P138B. I was wondering if anyone had the exact same issue we are facing, and found a solution. Thanks

That's true, I hope for the same.

I have not yet found anyone in Norway who knows what this error code means on Volvo S40, 1,6 diesel... :(

About Volvo fault codes, it refers to a lot of information, for example: Fault Codes WARNING!

When using DCU or DU, the fault code is displayed as plain text. For a further explanation, see “Reading fault codes”.

Afternoon. I have a volvo s40 1.6 diesel eco drive and an error 'engine system service required' and error 272 on the dash when holding down the button next to the speedo. Anyone know what it means? Car running fine also service was done 8month ago so doubt its overfilled oil. Thank you in advance
