Hello everyone, I'm having issues with my 2008 E93 that is testing the limits of my patience:
On April 6, 2020 at 92562 miles, I was getting problem codes P2B2C and P29F2. Looked up on forums here & elsewhere, looked like it was the High Pressure Fuel Pump (HPFP). I replaced it with an OSIAS fuel pump from Amazon with a 3-year warranty here: https://www.amazon.com/gp/product/B07K7G9R35. Before I get the inevitable "you should have gone with the BMW OEM" comments, they're not helpful right now, and I can get a free replacement if this is still the fail part.
At 94176 miles on July 15th, she threw codes P0306, P0303, and P0300, but was able to limp home. These are misfires in cylinders 6 and 3. Ordered replacement coil packs and spark plugs from FCP Euro, and found out my standard spark plug removal plug was not thin enough. While I was waiting for the socket to arrive, I just replaced the coil packs and the issue/codes went away. Replaced the spark plugs anyways when my ATLIN Thin Wall Spark Plug Socket 12pt/14mm arrived with Bosch ZGR6STE2 plugs. Car ran buttery smooth until...
At 94407 miles on August 10th, I noticed a small coolant leak near the upper radiator hose. Yes, it was the classic crack at the upper radiator hose plastic connection. I tried JB Weld first, but ended up replacing the radiator. Really enjoyed doing that in the 114 F days Phoenix was going through at the time!
Just when I thought I was out of the swamp, I'm out enjoying the car at 95005 miles after the substantial work I've put into it, and it throws codes P142E and P302C, and I get the reduced power/half engine light. If I let it cool down and clear the code, she will run fine until I'm at full operating temperature and going up an incline, such as a freeway exit, then she'll throw one of those two codes. After throwing the code the car does not run extremely rough like it did when the HPFP went out in April, but it's definitely not it's normal accelerating self.
It's been less than 2500 miles since replacing the HPFP, did I miss an underlying problem? Why does the car need to be warm to cause the HPFP problem? Someone please help me before I swear off BMW's forever...
