CrosslandX Terminal 30 Error

I also have a CrosslandX. Did you check the battery? A heavily discharged or defective battery can cause that exact problem. What about the fuse box, have you inspected it for any shorts or damage? You mentioned it starts poorly, is the starter motor engaging properly?

Thanks for the quick response! I did a quick visual inspection of the fuse box, didn't see anything obvious. I haven't load tested the battery yet, but it's not that old. Could a faulty starter motor cause this Terminal 30 error, or is that unlikely?

While a faulty starter motor could theoretically contribute to voltage drops, leading to such errors, it's less likely the direct cause. Given the symptoms and error message, a heavily discharged or defective battery remains the prime suspect. However, if you lack the tools or expertise to properly diagnose it, I would strongly advise taking it to a qualified workshop. An electrical fault could get worse very quickly.

Thanks for the advice! I took it to a local shop, and you were right, it was the battery. They replaced it and everything seems to be working fine now. The repair cost me 290€ Appreciate the help!
