S40 V40: - 2014 V40 CC - Won't start

bigjon001 · Aug 26th, 2019, 15:42

Hi.* Sorry if this has been mentioned elsewhere.

I have a 2014 Volvo V40 CC D4.* I began receiving a Low Battery Charge, and, after not driving my car for 2 weeks, she would not start.

I promptly went to purchase a new battery, put it in and she started up - no issue.

I went to the shops and drove around, until, that is, I parked at the mall.* On my way out, I attempted to start my car - nothing.* A loud click, and then what I assume is the pump starting.* After that - nothing.* She will not start.* I have removed the battery terminals and reconnected.* Still nothing.* I have tried jump starting.* Nothing.* I tried using a diagnostic tool, but no errors.

I have no idea what else to try.* Can anyone suggest anything?

Thank you!

Seems like bad alternator, or some serious battery drain when car is parked.
Did you get "low battery charge" on new battery, too?
What is the battery State of Charge and battery current when connected to ELM327? Try this free app:

Battery State of Charge should be 82-85%.
Battery drain with ignition ON (but engine off) is -10A to -20 A, with ignition OFF is -2A to -9 A, then settles to -0,7-0,9A for next 15-20 minutes. Standby battery drain overnight should be less than 25 mA (you can check in VIDA).
Alternator current with engine running is 25A-150A depending on CEM request), 0A with engine off.
