Juz to share my experience..
i have a proton persona elegance year 2010..
1st problem..after a year water pump squeeking sound...change it at the stupid SC at jalan peel sumhow they destroy my car and the RPM shoot to maximum whenever i start my car n aircond knob will auto on and off(Going back there so many times until cant tahan see them d wan vomit)...so go to COSE (since its the HQ and recommended) to change it..they say its the 1st time they see this RPM problem...so they ask me to leave it for a day...ok...(have to use KTM to go back since i stay at Puduraya area and COSE is sumwhere near to subang jaya)..Waste my time should told me earlier if cant fix on the day...went there at 8AM but they ask me to go back when they near to closing..
next day said ECU problem called me at 5pm how to go and get my car?..live so far..no other transport so leave again another day...
so went there the next day to get my car luckily a colleague send me..got my car everything ok...
so i was happy but sure thing my happiness was short live...now my car have a new problem suddenly i dunoe y the break disk and break pad is touching with each other or mayb some other problem have a very loud scratching sound like metal touching...very annoying....i not yet go to SC vertified since quite bz....
then i remember before sending to COSE my mileage written is 24508 if not mistaken but after getting my car back from COSE is 24544 they ed bawa my car go hantam and racing maybe...xS
it shud not be so far gap for my mileage just to change the ECU..hmm..this makes me wonder and scared to leave it at any SC again..
But i know for proton its impossible even u take good care of it...
Ahh, just a small matter I see. For the brake disc & pads coming in contact part, that is. You can get it rectified at any tyre shop. As you said, your mileage went up by 30-40 KMs, it's possible that they've been driving quite hard with your car and doing hard brakings. But then it's also crucial for them to do so to rectify ECU issues, so take it with a pinch of salt. Your car is already at 24k KMs, have you changed your brake pads before, ever? I know my Iswara had that constant brake disc & pad screeching noise also, but never bothered to change the brake pads cos it doesn't move around much.i have a proton persona elegance year 2010..

Go get your brakes serviced.

But I think it may be the throttle positioning sensor that's faulty in this case, which caused the ECU to not be able to control the idling and the RPM shoots up high. It should be stated in the receipt/invoice what part is changed. Mechanics usually tell you simpler and more general things to avoid you from questioning them and the need of further explanations.. Or probably they themselves don't know the name of the part they changed.. 
Then when the noise is gone I'll avoid any uneven road at all cost.. xD
