Testing and Diagnosing the E53 Webasto Thermo Top C/Z

[janzek-e46]

hello,

about the scanner i think to buy one that its almost the same like the china version but i'm gonna buy him here in slovenia  because of the coding part. I have a few friends with bmw-s and there would like to have some things coded But when i'm gonna buy another newer bmw i'm gonna buy the BMWhat from googleplay 

and as far as i know the reslers usb diagnostic has its software integrated in the usb adaptor, the one on my link has a standard usb plug and in the black little box its the software. I might buy the one of this two options.

How much cost the reslers usb adaptor?

Encouraged by all the good work being done and discussed in this thread, I spent time today sorting a remote for the webasto on my 3.0d. I wrote up a little thread about it on XOutpost.

Thanks very much to everyone who has contributed here and especially Jaynana!

Hello, I coded the webasto option, worked for a year or so.
Stopped working some time ago, hooked up my 140 coder and it says circulation pump error.
So will order a new one.
However, feeling a bit energetic I thought I started to investigate the telestart option.
It seems I have no wiring going to pin 1 on the webasto.
Also in the boot, there is no 3 wire connector.
So it seems not all cars are prewired. Mine is an E53 3.0D 2002/05.
Anyone else experienced this?

Hi,

How do I get to the pictures? my e53 has a heater, but only has a ventilation option on the on board computer.

If I put 12V on pin 1 should that start and run the unit? (assuming no faults)

It’s some time since I did it, but try looking at my write-up here from a few years ago:

Yes - 12V to pin 1 should fire up the Webasto if there are no faults.

jaynana, I am trying to sort my Webasto type c on my E53 as well... could you send me the PDF guides as well please?

[jaynana]

Hi, I wouldn’t remember the diagnostics as its been a very long time. I will dig into my archives and see what .pdfs I have next weekend (travelling right now).

Cheers

Hello,

I have a problem with my webasto thermo top c x5 e53 3.0d. When the car is asleep and i press the ON button on the Telestart it says OK but the webasto does not start. When i open the doors and the car wakes up and then i press the ON button on the telestart it fires up and works as it should. The car had a STH: K-bus malfunction error code on ISTA, so i did the test module where it said it had a voltage supply problem. I finished the test module and there was no problems it said that the voltage supply is ok and you need continue testing. What should i do next?

What is the battery state? The system has a ‘no start’ on the remote side if the vehicle battery or fuel supply is low. It’s to ensure there’s enough energy to start the dar.

+1 on battery age and condition will stop it working.
???? you open the doors and not start the car ???..

So what is happening is when the car is asleep. There is no lights on the gear indicator. I press ON on the Telestart remote the webasto will not start but the telestart says OK. When i unlock the doors the car wakes up and the gear indicator lights up. And after that when i press ON on the telestart it starts up just fine and works as it should.

About the battery: It is a original BMW AGM battery 2021 year 92Ah. Car starts even in -25 degree weather without problems

It’s long since I played with this so how it works is not fresh in my mind.

I’ve accessed my archives and I see various pdfs there. Happy to share pls PM if interested.
