Instead of removing the seat, you can remove the lower cushion. There is a metal catch directly under the cushion; you may have to use lever at the front left of the seat to slide it all the way forward to reach it.Unless you have the connector to the box, it's probably easier to access the wiring by removing the driver's seat. Six Allen bolts, two screws, and one connector. A five minute job, described in the Westy manual.
Tried my wiring harness + serial adapter again, but no luck. Then used the Autel adapter (sprinter benz), worked like a charm. Reset the lockout code and the Espar is alive again!Our D4S Espar (Airstream Westfalia 2005) is also not working now. Dead as a doorknob, just does nothing. I built a y-adapter with the circular plugs so I could tap into the line, then bought an adapter off of Ebay, shipped from Lithunia for about $65. It is supposed to work together with the Eberspaecher EDITH software but it's not working, I get "communication timeout" errors. An oscilloscope hooked up to the adapter shows that it sends out signals, but either it uses the wrong protocol, or the espar is so dead it doesn't respond.
The EDITHsoftware has several promising model numbers to configure:
D4S 252293 (Westfalia James Cook; Hella) [not tried yet]
D4S 252293 (Westfalia James Cook; Wehrle) [not tried yet]
D4S 252341 (DC James Cook NAFTA; Hella) [tried, doesn't work]
D4S 252341 (DC James Cook NAFTA; Wehrle) [tried, doesn't work]
Not sure what the Hella/Wehrle means. I believe those are relay manufacturers.
Today the magic Autel ODBII connector arrived in the mail, so I'll try that one to see if it can connect with the Espar. Will also try the Lithunian adapter with the model number 252293.
