My recent experience was:
1. Grinding sound from the belt area.
This happened on the first day of CNY when I was at hometown in Johor, the sound came after the engines heats up and will stay there until you off the engine. You can even hear it while driving but the sound is faint but still irritating. It is loud if you are outside the car.
It sound like it was one of the bearings connecting to the belt was not smooth. Awaiting diagnosis from FA.
2. Emission lights on for the past few days.
I have had this error light before, last time it requires me to upgrade a software at a price ( i think around 200+) to enable the new software to tune the engine. Now have to wait for another round of diagnosis from FA
For your information, my S40 2.4i has clocked almost 120,000km, so it is now in FA for the major service like timing belt and other major operations. This will cost at least RM3000+ Ouch!
Initial checking from FA , beside the 120k km service, I will need to replace my front brake disks (both ard RM1k+) and front brake pads (RM450+/pair) , also the battery (RM551).
This will be the biggest price I am paying for a service. I can feel it is gonna cost me around RM6k!
Be aware S40 owners. Feeling the pinch after warranty is over
Will update you guys with more details.
