Error Code P1125-62 and P1125-61 in Zafira

I recently bought this vauxhall zafira CDTI, 1910cc with a 56reg plate 2 weeks ago. The previous owner has been using it for minicab and thats what am using it for as well. when i got this car there was no warning lights on but 2 weeks down the line the EML came on last week then the coil ring light came on as well. The coil ring lights is always flashing when on but goes of after a long drive, like 25miles long drive. when i turn the engine off and back again the light comes back on, i also notice it produces blue tick smoke when idle and stops after a while or when i turn the engine off and back on again. I took the car to my local garage for diagnostic test it came up with this codes p1125-62 and p1125-61 my mechanic has turned off the EML light but need help to know what this code means. Am really confused and messed up as this car is due for an MOT and definitely wont pass with this light on.
Can anyone please help as would like some info so that i can know what am my next step can be.
Thanks
