Is my webasto dead? - Page 2

r2andy · 25th January 2018, 21:07

Sorry me again.

Just connected the heater up to thermo test and could only talk to it when bmw was selected, is this normal.

Ive not started it yet but i did a component test, on the circulation pump, it started and sounds fine but when I pressed stop it slowed to about quarter speed before it stopped and then threw a fault - circulating pump interuption.

And - glow plug/flame monitor short circuit.

I guess the glow plug needs replacing, but unsure about the pump.

Andy.

First of all was it sold as fully working if so you could try contacting the seller, so many of these are sold as working when came off the car but they are only working properly if they stay on and heat the water to 71 and go into part load and then go into idle mode when temp reaches 77, there are a, lot of in betweens possible such as switching off after a couple of minutes etc
I have thermis test and have to select BMW so that's not an issue it may depend on the type of interface you use.
Try clearing the faults and see if they reappear and did you test the air pump and fuel pump too as you only mention the water pump and glow plug,
You can check the resistance of the glow plug across, the plug terminals it should be 4 or below when cold, access the plug by removing the plastic cover on top of the FBH that is next to the exposed 2 and 6 pin plugs, push the cover towards the front of the car from the back of it slightly and it should lift up at the front with the aid of a small flat screwdriver

Well Andy,i fear you have a knackered PCB

r2andy · 26th January 2018, 09:36

I will contact the seller, as it was advertised as "fully working".

Mike, about the pcb, is it fixable knackered or knackered knackered?

Andy.

Send your PCB to Mike, he will sort it for you, Mike has done loads for me over the years.

Thought I'd jump into an existing Webasto thread. Just discovered that my 2001 CDT has a Webasto heater fitted in front of the battery, I assume it's OEM, not retro-fitted. Question is, what makes it operate - I can't find any reference to it in the owner's handbook, and I haven't found any switches for it on the dash. Is it supposed to start automatically, when the temperature drops to a certain level, or do I choose when it should be on? As it's there, it would be nice to make sure it works. I am going to be setting off for work at 6.00 or earlier for the next few weeks, and there is plenty of time for frosts yet, so it would be nice to get into a pre-warmed motor.

Surprised that it is not in your handbook. It is in mine on page 47. Look in index for "Heating - Parking Heater"
It will automatically switch on when you start the car and the outside temperature is below 5 degrees.
If you have not got a remote for it, is there a timing unit when you lift the centre arm rest?

Comfortably Numb · 27th January 2018, 13:55

Thanks for reply, ACS, No mention on P47, or in the index. It may be that in 2001, it was a new option, and the handbook had not been updated. There is no evidence of anything ever being fitted in the armrest cubby; I know from reading on the internet that's where the timers tend to be fitted on CDTis. I suspect mine is the basic installation - apparently activated either by opening the door or starting the engine. BTW, how long does it take before you start getting warm air?
