P006A code at 2800rpm, cold engine

[Seanyp]

2012, 3.0L D

Hi all,

I need some help, last year, I got the P006A Mass or Volume correlation bank 1 code and subsequent limp mode, so I replaced the MAF sensor with a new one and it sorted it.

Recently the P006A code has come up again, but only when the engine temp is cold, and the engine revs past 26-2800. If I manually shift and keep revs under 2000, and let the engine go to temp, the code won't come up.

From what I have read it could be something to do with the second turbo that kicks in at 2800.

Any advice?

Cheers

Was something similar to this covered earlier on this forum with a guy in Europe somewhere?

My memory isn't that good, but it sounds familiar ish..

is that P006A 21 or 22

Not sure if 21 or 22 [ATTACH=CONFIG]1939201

hi, you might need to get it scanned by a different device, or buy a gap idd tool, as the code can either be pressure too high or low, id guess too low, and maybe you have a manifold or inlet pipe leak.

Can you get live readings from that tool or any others you may have?

As pointed out, that isn't the best tool to have for one of these cars.

Yes, it can do live readings. What values should I be looking at when the code triggers?

The first readings would be manifold air pressure and mass air.

Also ambient pressure.

So MAP, MAF and AAP.

ideally you could record those inputs along with intake temp and post the log here.
