    11-31-7-531-813-M36 is the part number. Febi makes them aftermarket, which (for this particular part) are rated excellent according to PelicanParts user reviews (though I don't know how that data is aggregated). Some of their other stuff is meh. ~$60, plus get a new seal for a buck or whatever. Seal PN: 07-11-9-963-355-M131.

    The part number on realoem is 11317531813 (the same one) but it lists for $80.

    Just ask EAC Tuning or another forum vendor for assistance to make sure you get the exact right part. They're pretty helpful cats, and that's the way I'd go.

    i did the tensioner replacement and the old one had dead spring. but now when i cold start the engine i hear rattle for second. Didnt do that with the old one . ive driven the car after the change about 10miles, wondering if it just takes time to "settle" there or is there something wrong. There is no oil leaking from the tensioner hole. Thanks in advance. Good guides -> easy job! Thanks!

    Just did this today. Easy job. Took all of 10 minutes including coffee break. As I was pulling the old one, I had the new one soaking in oil. New one went in just fine and there was no rattle at start up. Used an OEM tensioner I picked up at the dealer for $62.14.

    this fix doesnt seem to address the rattle.

    the rattle isnt actually the chain. its the vanos gear wobbling on the camshaft.
    there is a new Beisan Systems vanos kit coming out soon.

    We've had several customers replace the entire camshaft sprockets and not have it help. Only one customer that I can remember came back and said that it helped.

    too many
    Got the febi for $65 out the door, at my local euro parts store.

    It made a hell of a difference in engine sound! My engine no longer makes a ticking noise. It just purrs now.

    My old tensioner (100k miles) was stuck closed!! Literally had no spring action!!

    Thanks for posting it. This job is a MUST DO for e39's and only takes 30 minutes!!

    Does this fix the tap noise at warm idle? Or is it strictly a cure for cold start rattle.

    My old tensioner was stuck closed as well, with the spring compressed.
    I would say I had 1/2 - 1 second of start up noise, maybe 20% of times.
    Now I have maybe 1/2 second noise, about 5% of times.

    should it even matter which direction? compression will occur from both sides equally regardless i would think. for example i've seen some coilovers out there that offer both inverted and standard setup(for exame BC coilovers) but springrates doesnt differ.

    What's up with the unusually high shipping rates for this little part? $18? Seems a bit much.

    Website pulled each part from a different warehouse. We combined them and credited your card.

    Thanks!

    When does the new tensioner design was introduced ? Before or after the end of production of our e39 ?

    I'm asking since I will pick up my 540i in about one week and it is a 4/2003 production.

    Every one I've ever changed was an older design. I don't know when the new one came out. I think it's just been within the last few years.

    the rattle isnt actually the chain. its the vanos gear wobbling on the camshaft.
    there is a new Beisan Systems vanos kit coming out soon.

    What if your car is pre-vanos and still makes the rattle though?

    I need to do this ASAP.

    After all of the help I have recieved from this forum, I thought I should try to contribute. Even though this thread is pretty old there may still be people like me out there who are just now needing to do this maintenance.
    The instructions on the first page are very good, this is a straightforward DIY. However, I found that the easiest way to install the new tensioner is to start it by hand rather than using a wrench.

    I started out using a wrench and socket and after about 5-10 minutes of frustration I decided to change my strategy. I got the wrench out of the way and put pressure on the center of the tensioner bolt with my left thumb. I then used my right hand to twist until the threads started to catch. I got it about 1/4 to 1/2 turn started with my fingers, then put the wrench back on to finish it the rest of the way.
    I was able to get the threads started in about 10-15 seconds using my fingers.

    I replaced my old tensioner with a Febi unit that has the longer spring. The only tools I needed for the removal and install of the tensioner was a 3/8 socket wrench with a 19mm deep socket. I had some chain rattle on startup that went away after about 3 seconds.

    Did my tensioner today. Pretty easy, no issues. I bought the genuine BMW part off ECS tuning and I was hoping to see a different spring than the one that was already in my car. Maybe a revised spring or something- but they were both the same. The used one did sit a little lower than the new one though- so I'm happy with that. Didn't have any issues to begin with so nothing to report really.
