Harmonic Balancer second failure
The harmonic balancer was first replaced by the dealer in 2015 at 67K miles.
It is failing again at 125K miles. Should I replace it again with an OEM pulley that seems to last only 62K miles or try something else, like the fluidampr? Any good experience with this one: https://www.tunemyeuro.com/fluidampr...35d-2009-2013/ Thanks |

Around January 2019, I proactively changed my OEM damper at ~67,xxx miles to a Fluidamper from tunemyeuro. I'm now at about 72,xxx miles and no issues.

I had no idea there was so much going on inside one of these! See the section half way down the page:
https://*************************/pr...15428796317786 Damn censorship! w h i t b r e a d p e r f o r m a n c e . c o m Thanks for the heads-up that they're a good alternative to OE. I'm getting a quiet but definite knock around 1000-1500rpm. I can only hear it faintly when driving on smooth road surfaces, but it's definitely there and if anything it's getting slowly worse. Is that likely to be caused by the damper going bad? M57TU2 330d, 138k miles. Also, I remember from putting the stretch belt for the HPAS on mine (~10k miles ago) that it seemed excessively tight. I'm confident it was the right part, and was either from Conti or Gates (can't remember)...could that have contributed to early/accelerated failure? |

#1 OE/70K-rubber tore #2 BMW/115K-rubber tore #3 BMW/159K-knock issue. The last one was FCP warrantied so either upgrade or buy from FCP and you only have to pay shipping.

OE damper failed last winter on wife's X5d 177,000 miles. Bought Corteco from FCP. Maybe it'll last another 177,000 miles. I know the engine will. Fluidampr is superior, just didn't want to mess with dialing it in. Plus Andrew is a good dude. I'll get that for my 335

Good Luck with that Dampr.
Had my original fail at 65k, then Valeo replacement failed at 94k. Fluidampr was replaced under notice for manufacturing defect at 120k. |

At 11Y and 115K my E70 factory vibration damper is about to give up.
What is the community vote for end of 2023: - FAI - Fluidamper - Corteco - Genuine Thanks in advance for your input
