  1. 1 Series & 2 Series
    Hi guys. So I'm new to this so please bear with me. I'm really struggling with my car. So what happened is that a few weeks back while driving the vehicles revs went over 5k and wouldn't change in to the next gear. So I slowed down and turn over and the vehicle died. Showed a lot of warning...
  2. E82 / E87 / E88 / F20 1 Series (2008 - 2014)
    Hi all, New here; looking for some advice on some issues I'm experiencing with my 130i LE. Overall the engine performs brilliantly; to me it feels like the car is producing good power and seems to be returning MPG I would expect. The only issues I have are quite an aggressive jerk (stutter)...
  3. BMW Coding and Programming
    Hey everyone, I hope this is a rather easy answer but I am struggling quite bad. I have a 2007 E60 with the N52. Bought it as a crank no start situation and it had spark at the time. Diagnostics lead me to replacing the battery and starter and now I don’t have spark. I have covered everything I...
  4. E60 / E61 (2004 - 2010)
    Hello to everyone, i am facing a strange problem i wouldn't expect it exists. I am reassembling my N52B30 engine and just put the cylinder head on top of the block and the 14 cylinder head bolts in their location and hand tightened it. But now i realized i am missing the four from around the...
  5. General BMW Questions
    Hello everybody. I have done a lot of maintenance to my E92 over the past few months, and I haven't reset the ECU (as far as I know) at all. I have replaced VANOS solenoids and changed the oil multiple times. I have also changed the air filter and replaced MAF. I was wondering if any of these...
  6. E90/E91/E92/E93 (2006 - 2013)
    Hello all! I have had this weird (whining?) noise coming from my N52 engine for about a week now. Nothing had changed with the engine immediately before this noise started occurring. It has no patterns, so no change with different temperatures, RPMs, etc. It seems very spontaneous and random. I...
  7. E60 / E61 (2004 - 2010)
    Hello All, This is not my thing, - posting stuff. But I wanted to share some of my (torturous) experience with replacing a 'valve cover'. It started with the 'loud whistling sound'. This one coming from the port located at the crankcase diaphragm cover. Many of you already know that it's caused...
  8. E90/E91/E92/E93 (2006 - 2013)
    I have a 2008 e90 325i that just doesn’t want to stop leaking oil from the valvetronic motor gasket. I’ve replaced it twice with the OEM gasket from bmw and on the second attempt I used some silicone gasket to help it seal but it just didn’t seem to do the job.it has the plastic tappet cover/...
  9. E60 / E61 (2004 - 2010)
    Hello everyone, First time owner here. 2007 530xi with the N52. For the sake of time I will try to give a relatively quick overview. I bought this car as a crank, no start vehicle. Previous owner had limited mechanical experience and I bought it thinking it could be an easy fix. Car would turn...

  11. E90/E91/E92/E93 (2006 - 2013)
    Changed new valve cover. Hope I followed all instructions correctly. When I started the car, saw white smoke coming from behind the engine. Stoped engine right away to inspect. When I started again the smoke came back on from behind engine close to the breather hose. Any suggestions on what...
  12. E60 / E61 (2004 - 2010)
    Hi, I'm the unfortunate owner of a 2006 E61 523i with a high oil consumption. The motor har been driving around 180k km. I got the car about a year ago and it has always had a very big oil consumption (1 liter per 1200km or so), which I understand from other threads is not that unusual with this...
  13. E90/E91/E92/E93 (2006 - 2013)
    I couldn't find what i needed so here's my first post... So for months I've been experiencing misfires from specifically cylinder 6 and 4 on my bmw 328xi 2007 e92 113k miles. It was at a shop for months sitting (really lazy mechanics)trying to figure it out it would idle really bad knocking...
  14. F10 / F11 (2011 - 2016)
    So i sent my Ecu to get tuned, I get it back n hook it back up and immediately once i turned car on i got Drivetrain Malfunction warning and chassis stability malfunction warning , Car idled rough for a few seconds and shut off . I read through a few post and did the Throttle Body adaptation...
  15. E60 / E61 (2004 - 2010)
    Heavy Buzzing/grinding noise coming from the drivetrain. Very hard to tell whether it s engine or transmission: only between 1500 & 2000 RPM very pronounced when car still cold. happens on 2d(slightly), 3d, 4th, 5th, 6th never happens in 1st gear and reverse. the noise tends to disappear...
  16. E90/E91/E92/E93 (2006 - 2013)
    So the story is, I had a leaking exhaust flange and thought to my self why not get a cutback system instead of spending money on the OEM exhaust, so got a quote for £550, went to the exhaust shop where they told me that they will fix the leaking flange for £150 and will do a mid back section for...
  17. 1 Series & 2 Series
    The time for oil change has arrived and my local mechanic said that he doesn't have castrol edge 5w-30. He had this made in germany oil called Adrenol 5w-30 synthetic. Is this oil a good option for my n52 128i ?
  18. E90/E91/E92/E93 (2006 - 2013)
    I’m currently working on a 2007 328i with 177k miles on it, and there is a quite worrying sound coming from it. It’s not lifter tick, because that comes from the valve cover and I have lifter tick too and I can distinguish the two while it’s running. The sound I’m worried about is coming from...
  19. E90/E91/E92/E93 (2006 - 2013)
    I’m rebuilding a crashed “run and drive” e90 sedan, and for some reason it came to me with quite a valve cover leak. As you can imagine, the headers were quite soaked and it smoked insanely bad anytime you wanted to test that “run and drive” claim. I was also getting a bit of smoke out the...
  20. E90/E91/E92/E93 (2006 - 2013)
    I'm looking into buying an n52b25, and the one i came across had compression readings as follows: C1 - 15bar C2 - 14.5bar C3 - 14bar C4 - 15.5bar C5 - 16bar C6 - 13bar Is that too big of a difference? Cyl 1-5 look great, but cyl 6's reading is considerably lower. The engine otherwise runs good...
