Air-con compressor fault

[banksider50]

Was out driving our 10 reg Fabia behind a bus. Thought Hell, that's a rough-sounding bus. Then, when the bus turned off, realised that it wasn't the bus, it was our Fabia. Suddenly sounded like a really old, rough bus or lorry. Carried on driving carefully and the noise vanished.

Parked up where we were going. When we came back to set off again the noise was still there but nothing like as bad. So, can't remember why, turned the air-con off completely. And magic. No noise all the way home. In fact, the car has never been as quiet. Like new.

So, talked to out local Skoda garage who said it must be your air-con compressor. Which is being replaced later this week.

Has anyone else experienced anything like this?

Hello, a own a 2008 Fabia with 1.6 BTS petrol engine. And climatronic. When the clima is on very loud noise can be heard in ****pit.

A had two new compressors replaced by a Skoda service. The last time we listen to another (test car) and the noise was the same.

So now I have the same noise as before changing the compressors. Maybe an factory problem?

Please take a look at "A/C compressor buzzing" and at "Air Conditioning Noisy" at the Roomster's corner. The same sound as described back there exists in many 1.2Tsi Polos.

The a/c compressor that is used in 1.2Tsi cars is identical to the one is used to 1.9Tdi and some 1.8Tsi cars, also there is only one radiator fan which is working in full speed when a/c is on. I personally believe that these two reasons are triggering the odd noise every time we use the a/c. Mine is a climatic unit.

Is it nothing just like behind the bus your car got the bus fumes and the sensor closed a flap to stop drawing outside air,

& went onto the air re-cycle from within the car.

(you have a sticky flap now!)

Similar to when you reverse and the fan or A/C can increase the air speed and not draw outside air.

(forward engine fumes)
