Hi guys, I need some help here. I recently had my ECU tuned and SHortly after, the CEL came on and when hooked up to a scanner the following fault code appeared: P010B

Has anybody seen this before? Anybody know what it means?

Many thanks for all your help.

you play with your airbox or filters recently...

Which tune did you get?

Crazy how some of these cars just dislike after market air filters.

Definition: Mass or Volume Air Flow "B" Circuit Range/Performance

I believe this definition is applied to all auto manufacturers.

Perhaps it has to do with the TB's being opened too much.

I could have to do with air filters/carbon filter delete, as others have said.

Do you have different filters and if so did you do that mod before, simultaneous to, or after installation of the new tune?

Thanks for the replies. The week before the tune, I installed the Cargraphic exhaust system - sports cats, secondary cat delete, x-pipe and valveless rear mufflers and changed the stock filters for new stock ones. Car runs well for 1 week with no cel.

Then, the ecru goes to Germany for the tune gets reinstalled and runs well for 1 day. Next day cel and P010B code. Since then have added gruppe m intake and k&n filters. Car drives great but the cel is still on and it has been reset 3times.

Could it be the MAF sensors on the Air filter housing? Cel not flashing. It's just on.

Thanks guys.

No problem. That's what this board is for.

Realistically, you've done some modifications. I would say that with this particular fault code, it may be due to the Gruppe M intake.

But, it's really hard to know. Btw, I'm not suggesting the Gruppe M intake is bad for your car. It may be great for it. I really don't know. Seems like it adds power as we've seen with the MCD version of it.

These cars throw CEL's too often for my taste, but then again it just shows you that these cars are dialed in very precisely from the factory and when you alter the parts, it's hard to compensate perfectly.

I'm out of suggestions at this point. I hope things work out for you.

My AMG tech said the MAF sensors are very sensitive. I had the same code they replaced the MAF sensor under warranty and no problems since.
