So I took the MAF out and cleaned it but it didn't need cleaning really because it was very clean, but what I noticed before taking the MAF out is that the air intake boot was not perfectly seated on the air joint (sorry for the lingo) underneath it. So when I put the MAF back I made sure the air intake boot was seated properly and the air joint was sealed.

I started the car and it idles better. It still had slight hesitation but quickly settled. I drove it and it pulled harder. I was surprised because I thought my car already pulled strong, but it was pulling ever stronger!

Next thing: have the injectors cleaned and do the carb clean up.

Mine leaked once or twice this winter when it was below -20C.

I got the same result when I googled P1345 code, I just don't know what the result mean or how I can fix it.
damn that's pretty bad!

Have you visited you local BMW Retailer to see if there is an outstanding recall based on the issues you have described?

If you wanted to check our www.bmw.ca/safetyrecall there is a new tool that allows you to search for any active recalls by entering your VIN.

Might as well give it a try if you are still struggling to find a solution.

Hi, it's the CCV (oil separator). In the winter it doesn't get enough time to warm up so it gets clogged with mayo-like thick oil. It's because I work close to home and it's rush hour so it's a short drive and the engine doesn't rep up so the CCV never gets the chance to warm up.

Anyway, I got another job that takes me on the highway so the engine will rev up more and it sounds like it's all clear now (it's also summer so that helps). I will wait until winter to see if the problem comes back. If the oil separator is cracked then I have no choice but to replace it.
