Have a strange problem with the car when you start the car and the climate control comes on and the fan starts in econ mode there is a click from a relay and the light dimms and the engine note changes to deal with the load about 5sec later same thing happens, but if you turn of the climate control all returns to normal turn it on and same thing happens.

Been getting lower than normal mpg over the last few weeks just as if you are driving around with the air con on but its set to econ so should not run at all as the out side air temp was 1c so had a look and the compressor ant starting so i was thinking what would cause such a change in engine note if it ant the air con compressor.

the car is a 130tdi sport 2003 Have any of you guys noticed this on your car any info would be good

Cheers

Similar sort of thing with mine, Econ button engaged temp set low> 20c no load on engine.
21c above - as yours, relay clicks /engine lugs down as though the AC compressor engaging and clicks on & off too.
Thought when the Econ button depressed, AC is off no matter what temp is called for.
Ideas anyone?
