Poor running MK3 Mondeo 2.2tdci

Hi to everyone in the group. 

I wonder if somebody could help me please. I have a problem with my 2006 Mondeo 2.2tdci. it started off when could it would idle rough for a few minutes until warm them would run fine while it was running rough there was no smoke and even under hard acceleration there's no smoke it pulls well in all gears. After switching off and leaving for a short while with the engine warm it will start but run at low idle (500-600 rpm) the battery light and engine light would come on and there's no throttle response after 30 sec or so the revs would pick up and it would run fine I have found out that with the ignition on the bolts would drop to 11.8 and when the lights go out and throttle response comes back its charging at 14.6 so I checked all the wiring on the smart charge system and cleaned all earth's but still didn't make any difference. I then went onto putting a code reader in but no codes are stored I have also changed the battery for a calcium one again made no difference. 

I found out after reading online the injectors could need recoding which I done this sorted out the misfire/hunting from cold but is still the same when engine is warm. I have now done a leak off test with the 5 min test.

The results look to me as they are over leaking but all very evenly cylinder 1 was 70ml cylinder 2 was 60 cylinder 3 was 60 and cylinder 4 was 70.

Has anybody else had this sort of problem and willing to share your wisdom. 

Many thanks for your time
