Take the Engine-Codes.com Tech Challenge and test your car repair knowledge
a 08 bmw 328i and when i try to start it it takes along time to start sometimes i have to do it 3 times and when it starts it shakes bad and a warning light comes on and a picture of a car lifted comes on to and also the check engine but the only code that comes on is p1727. i looked it up and it says its coast clutch inductive signature malfunction but what is that what part is that I allready asked this question but now the car started making a whistling sound I take the oil cap off and sound stops but all other symptoms are the same. Any help would be awesome thank you. Could it still be the crank position sensor. That's the only code that came up. And I started the car today and started fine with no problems.
