ticking noise on the dashboard

[Rigkraft]

Hi every,
sorry my first post is a question, I just bought my first Mercedes last night , and when you first switch on the ignition there is a noise like a loud clock ticking in the dashboard , to the left of the instruments , the car is a a 220cdi diesel , is this something to worry about ?

thanks in advance for any help

Does the clicking stop after a few minutes?

It could be the dreaded heater flaps problem. Plenty of posts on here about the problem, do a search.

I think you could be right Mr G , at least it isn't anything major , I didn't notice the "search" button

Thank you

You could try resetting the heater flaps, might be worth a go...

To reset heater flaps and actuators

Switch on ignition.

Press recirculated air and defrost buttons on control panel together for longer than 5 seconds.

The LED's in the defrost and recirculated air buttons flash alternately.

Wait until the LED's stop flashing (approx 30 sec) system set to defrost LED on.

Switch off ignition.

After 40 sec re start engine.
