X1 Hood Sound Insulation

Anyone interrested to get the underhood sound insulation?
All our X1 doesn't come original with the car.
I guess BMW didn't think it is needed.

But since the 2.8xdrive was introduce, I think the sound insulation should cut at least 15 to 20% of the timing chain noise.

I found that it is possible to get it thru BMW.

X1 hood soundproofing

I'd be interested in hearing people's experiences.
Strange BMW can supply it if they don't fit it to their cars when new.

Looks like an interesting and useful retrofit ,could you get the part number/link? . I am guessing it could be from the BMW X1 sDrive20d EfficientDynamics Edition which features newly conceived insulation technology for reducing engine noise that is perceptible inside the vehicle.

The PN should be 51752990573

You could find this part on realoem as well, but the picture showing does not depict the real part.

I don't think, that this PN is the right one.
In Europe and USA as well, you get a different part with this number.
And where are this pictures from?

If reasonably priced I would like one too. The mounting points exist on my hood (bonnet). Has anyone contacted BMW NA?

I am very interested in buying one, however, went to my dealership and they said such part did not exist. Showed them the thread in this forum, they looked for the part nr, same answer: didn't exist?

Now what?

Mod is not recommended. BMW removed this insulation on 1-series here in the US due to heat buildup.

I have it on my '08 135i...no problems. Must be cost cutting. Try Schmiedmann, they have it listed. thinking about placing an order?

I believe they officially discontinued the hood insulation on 1 and 3 series May of 2008. Our 2009 128i & 335i don't have it.

This requires some modification to the underhood to properly fit the X1.

I did not realize that there was an X1 specific shield. I thought the retrofit was the 1 series shield.

http://www.realoem.com/bmw/showparts...=51&fg=75&hl=5

This part is available from US part suppliers. Best price seems to be from Tischer: GETBMWPARTS.COM

Great find. I wonder if heat is only a concern with the 6 cylinder engines and not with the I4s.

Do the grommets need to be purchased separately?

The 1 series shield definitely does not fit the X1. I purchased the 1 series part for my 2012 135i. They still make the part, so I'm pretty sure its just a cost savings measure rather than for heat issues. I've had no problems with the one I installed on the 135i:

I'm worried about the X1 shield part number as it does show something different on realoem. Has anyone ordered it yet?
