TS, i know what you feel right now, i had been thru everything that u have been thru now, hours and days in COE, can't fix, head of department came, say leave the car and collect it tomorrow, same shit, i ask him go have a drive with me, he said " Oh, ada lagi bunyi ya", i said, "ya abang, macam mana, ini bukan pertama kali u duduk dalam tau?" , ends up, leave it for few more days ?! WTF?

A few advises for TS, if you can, try to go to smaller SC, some of them have very experienced mechanics! ( Exception for Inspira since it's a mitsubishi )

You may want to go to EON Service Center as they service the Mitsubishi Lancer.

My technician friend managed to fix all my waja cps problems within a day, this shows how unexperienced, skill-less and inferior the quality of Proton's technician.

GL to you and Wish you all the best!
