I always hate it when someone posts a problem they're having and then doesn't follow up with the resolution...
So I left this off last year when i was freezing my butt off in Telluride... i contacted a webasto shop in Grand Junction that said he would take a look at it... well they were very nice but didn't really deal with webasto's much and didn't have updated software or the proper connection to hook up to my heater.
After that i left GJ and went down to Moab to warm up and started calling around to shops in Salt Lake City, a few of the shops i contacted told me to contact another individual that does that stuff and i did, talked to him about it and he said he could take a look at it and adjust it to run at higher altitude... then when i tried to get a hold of him to setup an appointment he wouldn't return my phone calls... awesome.
At this point I thew in the towel on fixing it... i was frustrated with it and had been traveling for a while in my van and was a bit burnt out on that anyways.... fast forward to a few months later and I did finally take the webasto apart and it was COMPLETELY filled with carbon. So i thoroughly cleaned it out, put it back together, put it back in the van and on the first attempt it tried to fire up but didn't... make sense though cause it needs to get the fuel back through the fuel lines, however... additional attempts after that did nothing and it was flashing the error code saying it was locked out due to failed start attempts. Well to clear the lock out you're supposed to pull the fuse... well that did nothing. Frustrated with it i just boxed it back up and figured i'd deal with it later.
Well later finally rolled around and I was getting ready for a trip back to CO. I sent it off to stewart & stevenson in commerce city, CO. When i talked to them, they seemed very professional and like they knew what they were doing. A few days after they got it they called me, there was nothing really wrong with it... i was pulling the fuse while it was turned off... you have to pull the fuse while it is turned on to clear the lock out code! dammit.. haha
Anywho they cleared the codes and checked it and yes it was running rich, so they set it to run at higher altitudes sent it back to me and now it works like a charm. Ive been on the road a little over a week now hitting up aspen, keystone and fruita running it between 5000 and 9500 feet with no problems, I'll have to take it apart when i get back home to see how much carbon has built up. The guys at stewart and stevenson were awesome at answering my questions and told me to just call them if i'm having any problems so they can try to walk me through fixing it without having to send it back to them.
Essentially my problems boiled down to:
1) The heater was just not setup for the altitudes i wanted to use it at.
2) When i first had problems and contacted webasto support inquiring if the altitude could be an issue whoever i spoke to that time didn't know what he was talking about and said no it wouldn't be an issue (the times i called webasto support when doing my install they were very helpful and knowledgeable)
3) I wasn't clearing the lock out code correctly!
4) I simply had a lot of trouble finding a good webasto shop to work with... which was probably the most frustrating part to me.
Knowing what i know now when i first had the problem in tahoe i could have just pulled the heater, cleaned it out, and had it back up and running again... even if it was running rich i would still have had heat... hopefully now that it's adjusted to run at the higher altitudes it won't be an issue.
Sorry if someone else already covered a bunch of this stuff with the webasto heaters but i haven't been following the forums as much lately... it was getting too expensive always wanting to add the new toys everyone was getting
I run the smaller 2000 as opposed to the 3500 and that might help a bit...
