Faults

I have recently bought an 08 L322 and it is lit up like a Christmas tree. I have an LR3 and a gap tool for it and I used that gap tool to read the faults and I’m wondering what you guys think could be going on with this thing.

Suggest starting by checking the battery voltage / output which if low, can trigger random fault codes Thumbs Up

I plan to get a new battery tomorrow. What cold cranking amps do you suggest?

A new wheel speed sensor cured the problem.
