S60 d5 auto going into limp mode

[garrydiesel]

S60 D5 AUTO 2006 185BHP
Under hard acceleration the car goes into limp mode.
Message on dashboard states "engine service required" (or similar words)
When the key is turned on and off - power goes back to normal however message stays on dashboard.
I've plugged into my snap-on scanner, FAULT CODE - 2680 INJECTOR POWER CYLINDER 2, FAULTY SIGNAL
and another code... 135F MASS AIR FLOW (MAF) SENSOR FAULTY SIGNAL
(These 2 codes are constant, no matter how many times I clear the codes)
As soon as the car is under hard acceleration the codes come back (with it being in limp mode)
Obviously I know what the MAF code is, I don't know what the cylinder 2 code is... Can anyone give any information on this, it would be greatly appreciated.
Any replies would be appreciated, thanks.

First things first take your mobile number off. You never know who is lurking around. I would never openly post such personal details.

Second thing is you are in the wrong forum.
you will have better luck if you repost

Get the codes read with a proper reader.
Have a look at the other S80/V70/S60 Topic and search ECM6805. It's a common fault on these engines usually down to one of four things affecting boost. Split intercooler is the most common cause.
