Do your brakes work....I don't think I've ever been in a Volvo loader that didn't give a brake pressure warning. My L70 gave me a BP warning when I started it this morning. It stays on until I start driving. I let it warm up for about 20 min because of the cold. Sometimes when I get back in, I have an injection system failure message, and it will go into limp mode. I just shut it down, and re-start, and I am on my way. I am a big fan of Volvo equipment, but I do find that there are always codes. 99% of the time they are harmless, but my L70, and the 4 L90s are all the same.
