Started the car up yesterday and again this morning. I'm getting an odd whinny noise while idling, quick high pitched. I will get worse and higer pitch while accelerating. after about 4/5 miles it disappears.

I have no clue. I'm starting to regret spending £2000 on the car!

Ford Foucs MK2 1.6 Sport.

when was your last oil change and did they use correct oil? is it a TDCI?

Last oil change was on the last service almost 12 months ago. its a petrol engine

Could be the auxiliaries drive belt. Some people suggest applying some talc to it to see if the noise goes away.

i will have a tinker on the lunch break. would that get worse the faster you drive?

Possibly the auxiliary pulley wheels.

I will record the sound on my break.

typical! its didn't do it this time! i will record next time i hear it,

Belts tend to squeal, bearings tend to whine, so it's most likely a pulley bearing rather than the belt itself. My guess would be alternator but could also be power steering pump or air con compressor.

any way I can test the above?

Ok so i have recorded the sound from inside the car. This was me going around 40MPH on a B road leading to a A road. I have other recording if needed.

The noise is coming from the left hand side of the engine down by the belt system.

Any help will be amazing!

My guess would be the alternator as mine went 2 weeks ago and I now realise what I thought was a noise on the gearbox was the alternator slowly failing can't open your link to listen tho

First test would be remove the auxiliary belt and run briefly. If the noise goes it's definitely related to that. You can also turn the pulleys by hand with the engine off, if any feel 'loose' or rough that's probably the issue.

Alternative test is carefully lubricate the bearings in the pulleys with wd40 or similar while the noise occurs, if you lube the alternator pulley for example and the noise stops then it's likely to be that at fault.

Thanks. i'm not great with cars and do know how to remove or look at the aux belt. I have a indy garage appointment today. If its is any of the above what money am i looking to spend?

Really depends what it is tbh. Alternators aren't cheap if it's that, but if it's just a pulley replacement won't cost much. I never use garages myself so can't really estimate their exact prices.

I wish I could it myself. finger crossed for pulleys then

I paid £180 for an alternator fitted think it's a Bosch one at an indi

TomsFocus WINS!

PAS Pump. quoted £320 for replacement. Going to by the part myself as I have a mechanic friend who will fir the unit.

Just need to check i'm buy the correct unit, from some it looks like it makes a difference if you have air con. Mine DOES.

Is this the unit? http://www.ebay.co.uk/itm/FORD-FOCUS-MK2-POWER-STEERING-PUMP-2005-TO-2012-With-A-C-GENUINE-RECONDITIONED-/171580834816?fits=Model%3AFocus%7CPlat_Gen%3AMK+II&hash=item27f303c400:g:eiQAAOSwPe1T9Hsy

Look though tutorials on how to fit the unit, looks like just under the PAS is the thermostat, I had a thought this was on the way out. I'm guessing its the right unit

Anything else on the way to the PAS that could could be and worth replacing?

£320!? I really outta open a garage!

Not familiar with your particular engine I'm afraid but I'm sure one of the petrol guys will be able to confirm those parts for you.

Yeah £170 for the pump

120 for the labour

14 for the union.

and then break fluid.

Luckily i know someone.....

Any petrol guys that can help me out there?
