Id be curious to see if you can get away with much less torque on it to extend the bolt life.

The recall mentions that the original bolts were backing out and that is what was causing them to break. Perhaps they did not have the thread lock like the new ones.

The last posting in this chain came only a few months before the NHTSA issued a second recall on the same item for the E70 35d. Mine was done under the original recall in 2012. (I looked at the parts diagrams and failed to understand the moronic design, reinforcing my decision not to buy any other BMW for the next few years.)

A few weeks back my wife went by the dealer in Portugal for something else (which true to style they failed to address) however, they did come up with recall number two on this. At first I wondered if there was a problem with the fact that the car changed continents and they were about to perform the same recall again but it is actually recall nr. 2 for the same item that is being proposed.

I am bringing mine in tomorrow to have it done, curious if anyone on the Xoutpost has been in for "round 2" on the idler pulley recall?

Yes, it is a second recall for rhe same assembly and part from several years ago. Need to get mine done. I like the idea of getting a replacement bolt from ARP. If the problem is the bolt backing out and snapping, that seems like an easy fix.

When I recently took our 2009 35d in to replace the steering rack, our dealer insisted on replacing the idler pulley bolt, even though they had replaced it once before on a recall and I had replaced it again just a few months back. Maybe the third time’s the charm?

Dropped it off this morning for the recall (and received a Renault 3-cilinder as a loaner.....ugh). According to the SA, they replace the two piece arrangement where the pulley bolt screws in to the head of the alternator bolt (!) with a single bolt that holds both.

Before I dropped it I read the (4) engine codes (which prompted a CEL a week or two back) and apparently the DEF valve had stuck open and caused some displeasure but the codes did not come back on the 30 minute drive to the dealership.

We'll see when I go pick it up what they come up with. These guys are usually a bit lost as the US version does not equal the '09 Euro version....

The M2 Competition in the showroom looked very sweet!

Huh??? Maybe you need a new SA

I’m pretty sure the bolt covered by the recall is #5 in the attached diagram. FWIW I replaced parts #1, 2, 4 and 5.

And none of the bolts involved fit your SA’s description.

Correct, they replaced the bolt holding the static pulley.
