BN2 Heater Diagrams

Warning: BN2 GAS Heater is very dangerous and very unpredictable!  If you insist on fixing it yourself, do it in a well ventilated area and use extreme caution.  I would HIGHLY recommend that you get a specialist to fix it for you (the dealer)!

Here are some useful diagrams and links for the BN2 Eberspächer heater.
If You haven't already been, go to my Manuals page fro more info on the BN2.

Safety Belt Warning Relay Diagram

This is a hard to find diagram (that I took the time to create) of the safety belt warning relay.  The relay is located behind the fuse box (the bigger of the two).  Your car will not start without this (unless your smart like me and short pins "C" and "50)!
