Strange things.....

Got a new alternator belt as power was flickering, seems to have sorted that.

Got a new variator - no more diesel sound. Happy with that.

Got a new cambelt tensioner and pulley - blinking whining at cold still there, but goes when hot.

Do all 147's whine when cold? In am wondering if it is just a noisy alternator? I am not worried now that I know the cambelt and pulleys are all spot on.

Also.... Pressed the aircon button today, heard the beep, but aircon did not come on. Kept pressing, it eventually came on. Pressed again, it went off. Pressed again, would not come back on. Pressed a few more times - now works fine. Strange!

Hi Wilmslow

Not sure if it applies to your system but i seem to remember reading the aircon in mine will not operate if the temperature is 4 or below

Re: Strange things.....

COuld the whining noise be due to the water pump?

Re: Strange things.....

Pen, presumably because the aircon compresser won't operate correctly when the outside temp is too low. It would be like trying to operate a fridge outdoors in the Arctic Circle for instance..
If the Orange Snowflake is lit up on the display, the the compressor thereofore the aircon doesn't work.

Wilmslow, sorry to hear about your ongoing problems, it still sounds to me like a tensioner that is whining or the alternator bearings.

Re: Strange things.....

hmm... Tensioners all changed twice, so I reckon just alternator bearings. It has been seen and passed as ok by my specialist, just a little noisy. Based on that, I am happy to continue driving it - if the alternator ever goes my AA warranty should sort it. Just as well I have upgraded to Relay! Only real worry now is the fuel pump whine from the back seat, but, again, it tends to go once the car is warmed up. It sounds like an orchestra some mornings!
