My opinion is that I'm at 91,000 miles without a failure. I'm going to DIY this once in the lifetime of the car. It's not worth my time and effort to need to redo this because some OEM (non Genuine) part failed. It's not worth the cost savings. There are parts that I would buy OEM instead of Genuine only if the cost savings is substantial and the time/effort needed to remedy the problem is not that much. |

Update. Took it to the dealer for oil leak and mentioned my tensioner was jiggling. Mine is exactly like the op's video. Tech said that it's normal and no adjustment/replacement necessary

The belt is made by continental and the tensioner is made by INA. Those are both the OEM BMW brands, just not branded as "Genuine". Both parts should be about $100 or less if you source on from the right place online. The tensioner moved left to right at the top, like where the bolt is. The new parts are rock solid. Any movement would just allow the potential for the belt to be walked off which is risking catastrophic failure. My dealership said any movement in the tensioner is NOT normal.

Thanks for all the input, appreciate the help!
I looked it up in ISTA and now it makes much more sense. Is the "special tool" is suppose to hold the tensioner in there just when you remove it? [IMG]http://*************/wp-content/uploads/2018/04/rollpin.png[/IMG] [IMG]http://*************/wp-content/uploads/2018/04/instructions.png[/IMG] Just looking at it from above the engine bay it looks like it's suppose to jiggle.

^ That is exactly why you change your belt and tensioner. And also why you do the OFHG before doing so. Its literally $130 of parts total and maybe 5 hours of DIY labor.
Not saying his was caused by neglecting the jobs because anything is possible.

So there's two diagrams for this on RealOEM... 1. "Value line" - 11282457049 http://www.realoem.com/bmw/enUS/show...diagId=11_7066 2. Individual parts http://www.realoem.com/bmw/enUS/show...diagId=11_4454 I can't tell what exactly the "Value line" includes... I tried to look it up in ETK but couldn't see what the parts to the kit were... |

MECHANICAL BELT TENSIONER 11288604266
Deflection pulley 11288673720 These are my part#'s but you should probably google them and confirm or just check Realoem. If you're changing the tensioner, you may as well change the deflection pulley as there is a set of bearings that can wear out but it's completely up to you if you want to wait until you hear sounds or it fails. |

Interesting, its move a tiny bit, but mine before replacement was alot worse.
Don't think of it as a waste because it could eventually need replacement.

Changing the belt was good, for ease of mind. But the tensioner didn't change from before, don't know if new one is bad or just the way they are. Oh well, it's not giving me problems so I'll just live with it

Ran into this issue as well. Reached out to my local shop and he said what he saw from my video is normal. My idle seems to be running quite loud as well. Thoughts?

I just change my belt and tensioner and stationary pulley and still have the same jiggle. The noise did go away but how long before its back if the same symptoms persist.
After further inspection I can see it's the harmonic balancer that is warped and is causing the issue. This seems to be a pretty common issue on these engines. I'm surprised there isn't some type of recall. This is not normal, a warped harmonic balancer will ruin the pulleys, tensioner and belt again. It certainly cannot be good for the engine! I searched every where and I am surprised no one has an aftermarket fix. The OE balancer is close to $500 and likely to warp again. |
