Although Enginer went out of business a while back, we have spoken with suppliers and are now able to obtain replacement parts for Enginer PHEV systems.
Warranties are very limited and there is significant lead time on some parts, but feel free to call me and I can see what we can do for you.
On a related note, if you are throwing in the towel, and simply dismantling your current system, please contact me. I can remove your system and recycle/dispose of the parts properly.
