Sound like the swirl flaps are timed to fail at around this time of the life cycle. Interesting..!
Please tell all your friends who's using 525d and 530d about this known issue and get it rectified before any of the flaps get sucked into the combustion chamber, damaging the cylinder surface, head and piston surface. Scary..
The flaps seemed to be redundant and can be removed or replaced with a plastic flaps (available after they realise the design flaw).
Are these cars brought in by BMW Malaysia? If yes, then there are responsible "somewhat" and if its parallel importers, I don't think the car dealer will absorb the repair cost and its unfair to "attack" BMW Malaysia.. BMW Malaysia should at least help nego with HQ to subsidise the repair cost but technically, their product liability period ends after the warranty. So whatever help they can provide, is on goodwill basis. Unless its a design flaw that leads to safety concern that can threaten the life of the driver, passenger or even pedestrian, then different scope of social responsibility.
What was the mileage when the flap fail? Warranty only covers 60k km.. or 2 years whichever comes first. The expected life of the BMW engine is expected to be 160k km, as how they specified the maintenance requirement for the car i.e. LifeTime transmission lube, LifeTime axle oil and all meant 160k km which was published later when whole world is asking how long is "LifeTime". If you have reached 200k km when your flap fail, u should be congratulated because u have clock additional 40k km as a bonus.. and what was your question again??!
For instant, the first generation Saga has this body problem where the antirust or bitu layer on the body is corrosive to cause rust on the all 4 doors and roof and its obvious for Saga that's >6 years in age. What u expect Proton to do?
