Hi I'm glad you told me the model It's a smaller version of the Hydronic 10 I'll get some info together and post it on here If you know where the ECU is,I'll tell you how to test it without a vag com You have to bear in mind...an o\c includes the wiring going to the component

Another 2 non start faults are under and over voltage i forgot those....sorry

Can anyone tell me if this heater is made by eberspacher,and if so what model is it?

When I get a chance,I will look into it and post some info You can get fault codes out of the units with nothing more than a low amp bulb I'll also try to post a list of the codes and what they mean I need to find out where all the relevant parts are on the Galaxy first(like the ECU) p.s. the link didn't work...it just comes up as not available Forget that...it works now

The sensor that gives an overtemp fault is a positive temperature coeficient resistor,if it starts to break down it will give faulty readingsIt also has a lower warning range and an upper cutout range,so it may just be warning that it is approaching overheat.To reset I will have to know exactly which model it is...it can be done with a piece of wire...but it will only remove the last fault code,which will let you start it but 1 fault will stop it again...if you have the diagnostic meter you can completely clear the memory. The non starts are 1 Fuel metering pump open circuit 2 glow plug open circuit 3 flame sensor open circuit 4 fan speed error 5 temp sensor open circuit The problem with the failed starts is that the unit doesn't actually know why it hasn't started.....so even if there is no fuel,the unit can't tell and after 5 goes decides that it isn't safe to try again......the inline fuel filter is very fine and easily blocks...this causes the the unit to "sputter"and eventually stop.

That's because it didn't cause a fail start,if the glow isn't working the heater won't even try to start...it does a set of pre start checks,and if everything is ok...then it will try to fire up...if it detects any faults at all it won't even try...........however the fault will remain in the memory

I'm an Eberspacher service engineer...I can say with some certainty thet any reason will result in a lockout if it causes a fail start

I'm not certain....but I'm fairly sure from the replies that the heater is made by Eberspacher....it can come in petrol or diesel form...and the good bit is.....they have a memory unit fitted.If they fail to start for any reason 5 times...they are locked out until reset

Hi I know this may sound silly,but how low do you let the tank get before you refill it.....water slowly accumulates in the bottom of the tank if you fill up early....white smoke is an indication of water in the fuel.....it gets sucked in and trapped in the filter
