Strip down and rebuild of Eberspacher D9W (D5W)

In this video I strip down and re-build an Eberspacher D9W which is similar to a D5W or the Hydronic hot water heaters made by Webasto.
I locate the problem with the seals inside the unit and put it back together.
Once reassembled the unit is screwed to my door where I run it up and heat a radiator to 75 degrees
This is the 24v version of the heater and is powered by two YUASA batteries.
This forms the first of three parts to my homemade heating system
Hope it helps
AJ

P.S. I know it's upside down

Hi AJ, do you happen to know where I can get a used ECU (steuergerät) for the D9W? It seems mine is dead, but would like to keep this unit.
