this is on my moms mk5 fiesta, the other day she said the car cut out whilst driving and started again, I took it out this morning and it struggled to start up, luckily I got and OBDII reader and app on my phone (used it before on the car as was correct) so was able to check for error codes and got 3 of them

U2510
U0155
U1262
what are the codes for?
