2004 E53 X5 3.0d Sport - ticking sound

[Smeeagain]

I made this post at the weekend but it seems to have disappeared

My X5 has developed a ticking sound (only when the engine is running) which appears to be coming from the papsenger drivers door area. At first I thought it was the motor in the mirror or the electric window.

When i get out of the car and go round to the drivers door its difficult/impossible to hear due to background or engine noise. Sitting in the passenger seat it appears to be coming from the door pillar/lock area.

It sounds like a sensor or relay kicking in and out. Everythign (lock/mirror/window) appears to be working fine. Switiching the engine off and back on sometimes makes it go away

Does anyone have any idea what this might be and how I resolve it ?

Thanks

Not a problem, that is the heater

When temperature is low, you can really hear it chuck away.

Love these posts!

They come at this time of year and I was one of them!

You have nothing to worry about - the Webasto is kicking in when you get 7 celcius or less...

i agree with dumb and dumber above it sounds like an old gas fire when it gets going.Nothing to worry about there smee infact it shows you that the webasto is working and doing it's job

so basically it kicks in below a certain temp to keep the pilot warm in his cabin ?

It's initial purpose is to pre heat the heavy/thick oil in the derv's AFAIK...but can also be used as a cabin heater as an extra
