Vrs discharge.

Hi All,

We have a MK1 Octavia VRS, been a good car for the past three years, but now has developed a starting fault due to a a discharge over night. It only happens intermittently. I put a battery on it out of cause, charging systems works fine. Did an amp leakage test with the alarm armed and it draws 0.15amp. Which I didn't think was to bad. I've been told of alternators faults that may be the same thing but I thought I'd ask here first.

Any one had this?

Thanks in advance.
