Hi all, I had a few issues with my battery and car starting few months back. I got a brand new battery in July and the car worked find and I had no starting problems.
At the same time, I did a parasitic draw test using help on this forum and confirmed that there is not a lot of draw causing battery to drain when off. Battery is a Varta I1 110AH 920CCA.

Now 6 months later, my car is having starting problems again. When I turn the ignition on, I often get the Parking brake, ESP and Glow Plug lights on and they stay on. If this happens my car doesn't start. I still have my old battery I replaced 6 months ago. If I jump start using my old battery the car starts fine. I have charged my car battery and left it on trickle charge for the last 10 days without using it. The battery shows fully charged, but I am unable to start the car. I made sure the charger is working using a volt meter. What could be the problem?

I lost my bluetooth OBD scanner, so unable to read any codes now. Last time I checked after replacing the battery and the control flap in July, there were no codes.
