Hi this code came up a couple of weeks ago.

Car ran fine until I could not start it. Battery was dead. I jumpstarted it . It ran fine for the day. Mext morning, battery was dead agsin
Brought it to the mechanic and he ran a bunch of tests... Called me and said he could not fine anything else but the battery that, in his words, was weak.

Replaced the battery and will see tomorrow is the battery hold its charge.

Any idea or suggestion as to what it maybe?

Thx all for your appreciated feedback.

P06A3 - Sensor Reference Voltage "D" Circuit/Open

I had the same code a while back while I was dealing with a bad DPF filter and glow plugs/wiring.

Can't offer much more but with any luck it helps you on your diagnosis.
