Many thanks to everyone reply, I just visited one of the accessories shop in Penang and found the Slime Repair kit, RM70 (the one come with a green sealant + a 12V pump). When I'm about to make my payment at the counter, I ask the guy to test if the pump work. When he open up the package, the cigarette power socket broke and fell apart. (Plastic material deteriorate). Then he take another one, same issue, the cigarette socket plastic crack and that is their last stock. End up I did not manage to buy. My advice to those who purchased Slime Repair kits, please constantly check the pump and everything. Don't end up surprise when you need to use it at the roadside. Another experience I wish to share. My E90 front wheel arch plastic cover (the 6x5 inch square plastic cover when we want to replace light bulb) fell off and went missing. I went to a renown 3rd party mechanic shop here and they quote me RM38, the same day I drop by Auto Bavaria and bought it with only RM8.90 !!! I think if parts that doesn't require intensive workmanship, we should check with AB for comparison, AB not always expensive. A separate question, Tesco Penang on sale a 4-Liter Castrol Edge 0W-40 fully synthetic oil with only RM136. Anyone know what is the normal price? Is this oil good for E90 320i? I know most recommend is 5W-30. If oil thickness of 40 give a little bit more protection with perhaps little compromise in power and fuel consumption. Why not. (am I right?)
