Help with fault codes
Hello all, new to the forum and hoping someone might be able to help me.
We have a 2008 LR2 which has been functioning perfectly, all of a sudden the check engine light came on.
We got the codes read and it came up with three codes -- p0458,p0057 ,p0051, It seems there must be something common causing all of these..
They all seem voltage related.
Any ideas ? Where can I start looking to try to diagnose this ?
Any help appreciated as I do not know where to start.

When the battery gets old electrical gremlins show up
how old is the battery?
for my LR2 the fuses in the engine compartment got corroded when my battery failed
i replace all of my fuses
i also replaced a few relays
get a copy of the electrical diagram and check what’s in common with the codes
here is a video of a Volvo owner that did exactly that
note: the xc90 in the video has an almost identical engine to the 3.2 in your LR2 and the electrical system should be very similar if not identical
good luck
