Just found this: "The NEW Webasto Air Top 2000 STC is now available on our online shop. This product is the further development of the Webasto Air Top 2000 ST and has the same dimensions and technical characteristics. It also runs under the same legal operating licence as the Webasto Air Top 2000 ST. It uses the standard fuel pump DP42 as used in the Webasto Air Top Evo 40/55 heaters. A change of the applications when using the new heater is not required except for using ta different metering pump ad harness. The Webasto Air Top 2000 STC will ensure full W-Bus compatibility and full operation with the NEW SmartControl and MultiControl without using the Unibox. Can be used in conjunctions with the Webasto ThermoCall TC4, this Can also be purchased on our online shop."

Sounds like it's a newer improved version of the ST which would explain maybe why ST test equipment won't properly interface with it. Updated heater as of 2015 (in Europe).

Butler Technik sells both the ST and STC in the U.K. So it looks like the ST is an international design that's the same everywhere. I'm guessing that the STC will be coming to the US sometime soonish.

Down the rabbit hole. So I'm pretty sure the webasto dealer you went to may not have had the newest WTT diagnosis software. It appears that most people use v2.13, but that the STC support was added in 3.0 or 3.2. Dealers should be able to download the newest software here: http://dealers.webasto.com

You may want to check what version the dealer was using to attempt the connection to your heater. Having done a lot of electronics work experience suggests that the reason they couldn't connect is because the device model number wasn't recognized. The data comes out of these heaters as serial, which is a pretty much universal method of data read/write for interfacing with basic electronics.

One other avenue is that you may want to call Webasto in Germany and see if somebody can explain what a US dealer needs to do to connect and diagnose your STC (or maybe a helpful dealer in the U.K. Can tell you what software version they use to diagnose an STC).

Thanks for your help everyone.

By chance, i took a photo of the computer connected to my Webasto; i can see that they are using version 2.09 of the software... this might be why they could not detect the STC. I don't want to go back to that shop though; they might be good installer but i'm not too confident about their troubleshooting skills...

I did a last attempt today. I simplified everything to the minimum...

Still the same behavior. I wasted enough time trying to figure this out; it's removed from the van now and will soon be shipped.

This video shows that the combustion ignite after the "abort" sequence (3m25):

Any update on this issue? I was planning to install a Webasto in my Transit - I put a hold on it until this is sorted out.

Just got news:
Carbon Buildup.
(again, we are at sea level and used the heater for extended period of time. Carbon buildup should not happen)

Just like another member here.

They want to clean it and send it back to us, but i see no reason why the problem will just disappears by itself! The other member with the same issue had to clean it twice already.

I asked for a replacement unit, because if i have to ship it to U.K. every time it has to be clean, it will cost a fortune in carrier freight.

Let's see.

I'm curious if any others here have had the carbon build-up issue besides myself and Antoine, and what typically causes it? I've heard that it's from incomplete combustion in the burn chamber from the heater not being hot enough?

Found that in the Espar (not Webasto) manual:

5. CARBONED BURNER CHAMBER – these are non-warrantable unless caused
by a primary failed part covered under a warrantable failure situation.

a. Caused by a restriction of intake or exhaust.
b. Caused by improper angle of fuel pump, pump must be 15 – 35 degree
angle up with the outlet / harness connection being on the high side.
c. Fuel system that has had improper amount of additives injected into the tank.
d. Fuel system with any kind of oil being used in the fuel.
e. Short cycling caused by improper application or electrical power
connections.

. If burner chamber has carbon build up replace the burner chamber
1. Soft carbon: (non-warranty).
a. Is an indication of over fueling (Pump angle).
b. Restricted exhaust.
c. Restricted intake.
d. Plugged blower wheel.

2. Hard carbon: (non-warranty)
a. Is an indication of too much additives.
b. Heavy concentration of bio-fuel.
c. Short cycle of heater (recommended minimum runtime is 15 minutes).
d. Road debris (reposition combustion air intake to a location not to pick-up debris).
e. Clear codes and run unit.

There is more info at page 31 & 31:

What i understand is, there are may possible source. It will be difficult to narrow it down the the single source...
