Engine malfunction error and weird error codes

Hi all,

I have a 2009 focus MK2.5 1.6TDCI zetec with about 116k miles on the clock. I've just come back from work and for the first time that I've seen the 'engine malfunction' error come up on the dash. The car drove perfectly on the way home. no weird noises or limp home.

When mentioning this to my wife she apparently saw the error thursday last week when she was moving my car but didnt tell me as she thought I was already aware . however I've used the car for 10+ trips since then and I didnt see anything. However since the first time I saw the error it seems to be consistent now.

I've used forscan and found the following codes:

PCM:

• Code: P0704-28 - Clutch switch input circuit malfunction
• Code: P2585-61 - Fuel Additive Control Module Warning Lamp Request

FACM:

• Code: P2409-60 - Fuel Cap Sensor/Switch Circuit Range or Performance
• Code: P1922-60 - Fuel Additive Level Circuit
• Code: B1317-20 - Battery Voltage High

The last time I checked codes on the car was probably 5-6 months ago. The only code then was the first one in the FACM P2409-60. I've tried resetting this and it keeps coming back. I have a feeling the magnet is missing from the fuel filler flap. This code has been there since I bought the car, 1 year ago. So I was aware of this one. It never caused any harm so I never bothered with it.

Some of these codes could be old but they dont really point me into the direction that is causing the error. If the fuel additive tank needs topping up I was expecting P1927 or P1932 to be present.

Any insight would really help. If it makes any difference, I'm fairly sure the DPF has been gutted on my car by the previous owner. I've also attached the DTC log for full analysis. My next course of action was going to be jacking the car up and visually looking at the additive tank to assess if it is empty or near empty. I was also going to reset all DTCs and monitor which ones reappear, i.e. presistant issues. However Im far far from an expert here which is why I came to you guys
