    Hello. A few days ago the engine light appeared and I checked the bimmerlink application and the following errors appeared. I erased the error and continued to ride the car. The car is moving normally and pulls well. Today when I was starting the car I noticed that the coldstart did not...

    Hi, I was a long time owner of a N52 E90, I finally had to part with the vehicle after hitting 325,000km due to work =( I recently picked up a used N54 - 2008 335xi. The vehicle has significant wastegate rattle when letting off the throttle. I purchased knowing there was this issue. My...

    Hello, Lurker but a First time poster here. I am having an issue with my 2012 BMW 328i. I've had the car for 2 years now and about 3 months after buying the car I started getting a Drive Train Malfunction Error (loss of power) on the idrive display. When I turn the car off the drive train error...

    So I bought a 09 335i Xdrive coupe from a private seller on June 12th. Everything was beautiful on the car including the paint, engine, interior quality, etc. On the 14th the engine light came on and stated that the was an engine malfunction with low output (assuming it's the dreaded HPFP). I...

    Had my "new" '09 335i xDrive checked by trusted mechanic to keep dealer's feet to the fire on fixing anything amiss while I can still cancel the purchase. Mechanic reported (among other misc. things) "Turbocharger waste gate pushrods worn out; No boost faults present at this time." But he...
  6. General BMW Questions
    Getting a killer deal on an e92 335i 6sp sport package etc. But it's very high mileage and on the stock twins (it's been stock it's while life and driven across the country many times) I have money and time if the turbos do go but it would be nice to have a Pre Purchase Inspection Done on the...
  7. F10 / F11 (2011 - 2016)
    I have a '13 528i xDrive and it makes a rattle noise during acceleration. Whenever I search up my symptoms, I see a lot on N54 wastegate rattle. The symptoms sound very similar to mine but I have yet to hear anyone mention this for the N20. There seems to be some extended warranty for the N54 so...

    I have a 2009 335i coupe w/ manual trans and 76k miles on it. So recently I hear this rattle not on start up, or idle, but after a rev. When the rev dies its a pretty loud rattle that follows it. Always at low rpms while driving I hear it. So After some research it seems to have something to do...
  9. E90/E91/E92/E93 (2006 - 2013)
    I have an '07 e92 335i with 60k miles on it. Anyway, I've noticed that when I start up there is a rattle coming from the rear (butterfly flap) and occasionally the engine bay. However, when I rev it it doesn't hiss like the Wastegate rattles on YouTube but I feel like there's something wrong...
  10. E90/E91/E92/E93 (2006 - 2013)
    OEM turbos on the e93 335i are singing death rattles, so it's time to upgrade. I did all the prerequisite searching the forum, but all the discussion I found on this topic was either outdated or not terribly thorough, so here goes again... Also- conversations on other forums quickly devolved...
  11. E90/E91/E92/E93 (2006 - 2013)
    I been looking for a 335xi coupe, 6 speed manual, for a while and i just found one that i really want, its an 08 with 63k but im a little skeptic because of the mix reviews online, here is the history on the car: According to carfax: - 0-38,593 miles it was a corporate buy so no record on it...
  12. E90/E91/E92/E93 (2006 - 2013)
    I am having issues with one (or both) of my turbos. There is a rattling noise and the wastegate isn't dumping pressure any more. I have seen that BMW NorthAmerica (which does not include Canada) has extended the warranty on the turbos and wastegates to 8 years/82,000 miles (132,000 kms). BMW...
  13. E90/E91/E92/E93 (2006 - 2013)
    We have recently begun to replace both turbines along with the head-gasket on a 2006 335i with just over 100,000 miles on the N54 engine powering this vehicle. The car was brought in due to a rattle coming from the engine compartment. It was found that this rattle came from the actuating...
  14. E90/E91/E92/E93 (2006 - 2013)
    We have recently serviced an N54 unit due to both turbine wastegates having developing a rattle. Although the internal components appeared to be in fair shape, both turbos had an audible rattling noise upon activation of the vacuum actuated wastegates. With this becoming a common issue with the...
  15. E60 / E61 (2004 - 2010)
    Hello, I have 2010 BMW 535i xDrive, completely stock. I have been hearing the rattle from the waste gate for sometime now, took it to the dealership and they said "it's normal, the waste gate is normally a loud component" and I should keep driving it. The rattling has now gotten much worse and...

    OK so if it were possible, because I am almost positive I have a way to do this, who would be interested in having a turn of a knob, no map switching, boost adjuster for their JB4/3? I am going to install on my car and collect data on my laptop shortly.
