Fenderboy Posted October 11, 2013 Report Share Posted October 11, 2013 Hi all, had my E46 325i touring for nearly a week and the first problem presents itself! Was waiting at a jebel crossing earlier when the car began idling a little erratically, nothing dramatic. As I pulled away it sounded almost as if it wasn't running on all 6 cylinders. Power was through the floor, really sluggish. I nursed it to where it was going and started/stopped it a few times. I then put it up on a ramp at my friend's house whilst we looked underneath. We brought the car back down, all the time with the car idling fine. Poking around the engine bay, we found a split, well, a massive hole in what I assume is the crankcase breather, it tees off from the main air inlet after the filter. I didn't have anything to hand to make a temporary repair, so just thought I'd nurse it home. When setting off, all was well again. Power was back, car pulled really hard. Got home, went out again and it started back lumpy again and began cutting out. I took it straight back home and we went out in the wife's car instead. Could this (scary to me) behaviour be a result of the hole in the breather pipe, or do you think something else is at fault, maybe a coil or something? I'm going to try and make a temporary repair tomorrow and see how I get on. Thanks for reading, sorry about all the words!!!

Fenderboy Posted October 11, 2013 Author Report Share Posted October 11, 2013 *level Bloody autocorrect!!! Thanks, feel a bit less gutted now ha ha! I thought it couldn't be anything TOO serious, as it did come right for a time before it went bad again. Will try and repair until I can get a new one ordered. Cheers for the reply!

B0B Posted October 12, 2013 Report Share Posted October 12, 2013 (edited) It sounds like you are describing a split in the lower intake boot where it T's off to the idle control valve. They aren't that expensive to buy from the dealers. Edited October 12, 2013 by B0B Quote Link to comment Share on other sites More sharing options...
Marcus Posted October 12, 2013 Report Share Posted October 12, 2013 has to take the mickey sorry. they are well known for boot splits. go to dealers aint too expensive. they come in 2 halves best buying the lot and fitting in one go. the lower one can be a pain to get to.

Fenderboy Posted October 12, 2013 Author Report Share Posted October 12, 2013 No prob Marcus, I type too quickly! So we all think the symptoms fit the split boot then, great.
