Ford smax codes

[Roberts95]

Can anyone tell me what these codes are and what are the fixes? U0405:00-68 & U3001 00 08 it’s a Ford S-Max 2007 2.0 diesel it also has a small leak on the alternator side I think it’s diesel because when it comes to a stop you can smell diesel sometimes, if anyone has any idea what that could be I have looked under the hood and you can see there’s been a leak, but I’ve cranked the engine while someone looked and there’s no obvious leak. The alternator belt has sprayed the liquid everywhere

Any DTC that begins 'U' is a communication error between modules. They are in themself not a fault.

I think you need help from someone who has knowledge of car engines. PS. In the UK our cars have bonnets.

Didn’t mean a hood I was tired ha! 
 

I’ve checked the fuel filter ect and it’s bone dry wish it was a bigger leak so it was easier to pin point
