Webasto! Why won’t it work on its own…. VCDS enabled??

If anyone as a spare webasto circuit board that displays the real coolant temp I would be great full of it. Mine says 112 deg C. All the time

It's the little white resistor by the metal plate. I think it's impossible le to know what rating etc it is, I sent mine to be refurbed. They changed the capacitors too as they were cracking. Wad quoted £50 but ended up free. Link further up thread I think. ...I do have one spare but inprocess of mending my own.....
 
Evening all,

Great thread this. I’ve just nipped out maiden to change my engine ECU soft coding from 00005 to 00002, ignition off, then on again and I was presented with the dimming interior light. I can confirm that my webasto is now firing up by itself.

Sat here watching the measuring blocks and the coolant temperature is rising quite nicely.

That’s Project EUD sorted, will move over to Project OEM in a minute.

Awesome teamwork on this issue that has been an issue for many.

Kind regards,

Tom.

My thoughts are if the temperature of the webasto isn’t showing 112 degrees and the glow plug works, it’ll probably go.😀
 
Me again.

Same result regard the Webasto automatically starting in Project OEM. Unfortunately it’s not quite firing up as it’s sat at Start and not full throttle/part throttle. It eventually comes up with malfunction in Group 001. Not registering a fault though so some deeper investigation into this particular car I guess. All the temperatures are spot on though but think I’ve got a flakey flow plug in this car.

The Webasto exhaust is only slightly warm and not fully at flame-on. I’m sure I’ll fix it eventually.

Time to get the spare Webasto out of storage I suppose.

Does reverting from soft coding 00005 to 000”2 mean that I’m no longer running the remapped settings, I guess I can simply go back to 00005 in the warmer months.

Kind regards,

Tom

Your running a partial remap on 00002

Mr blacks webasto is working but Mr Silvers isn't, both have 0005 coded ecus. I have the original from Mr Silver, will throw that in and see if I get any joy. How is the ecu switched to 0002?

Morning Tom,

Hook VCDS up to the vehicle, ignition on (no need to have engine running) and select Engine 01. Wait for it to load up then select Coding 07. It will display the current software coding as 00005, simply change it to 00002 and tap do it. Go back and exit VCDS, ignition off then on and start the engine. All being well, you'll hear the fan start and notice the interior light flicker if you have them on.

For pure satisfaction you can use VCDS to monitor Group 001 in measuring blocks of control module 18 (Aux Heat) and you should see the coolant temperature rapidly rise and see the status go from Start - Full Throttle - Part Throttle and Off. hopefully that’s the case and it doesn’t come up with Malfunction.

The above easy to follow procedure is all I done in both of the fleet last night which cured the blocked signals from the ECU. Both Webasto heaters went through the start sequence but only one actually fired up. Project OEMs glow plug has a fault which is no doubt from me cooking it every winter trying to get it to work going through the output tests multiple time; when it was never going to work due to the coding being incorrect.

So wish this was realised a couple of years ago as it could have possibly saved a Webasto swap as the glow plug used to create a plume of smoke but not anymore unfortunately. The good thing is I have a few spare days holiday to use up so might take a day off, give the other driver here the EUD A2 and get the Webasto in the OEM A2 swapped for the spare I have in the garage.

Kind regards,

Tom

Hi Tom, two q's does this affect the engine remapped power map, and can you do this with vcds lite? Cheers

Morning Edd,

The answer to your first question is yes. Using 00005 is the full remap and 00002 is the standard or a partial remap. Switching back to 00005 in the warmer months (if you have a working Webasto) or when you deem it necessary.

Unfortunately I’m unable to answer ykur second question as I’ve never used VCDS Lite, only ever had full VCDS. If you have VCDS Lite then please give it a go and report back as many people will be after doing this during the cold spell I’m sure.

For anyone else reading this who would like their Engine ECU reverted back to 00002 who hasn’t got VCDS then I’m happy to help out (free of charge) if you’re ever passing J22/23 on the M1. I’m also heading to Wakefield today (staying overnight) and will have the laptop with me should that benefit anyone.

Kind regards,

Tom
 
Many thanks Tom very informative!!

Does this mean any remapped ecu with the full power map will be set to 0005, so if you buy a new to you car is simply checking with setting the ecu is showing a fail proof way of telling if the car is remapped?

A YouTube video of this procedure would make great viewing lol!!

Cheers
