Under Bonnet Insulation

Have any of the Aussie 135's missed out on this.:iono:

My car HAS the insulation.:smile:

This is an interesting topic as it seems to happen to alot of imported car brands from Europe...

I have 2 Opels (Calibra and Astra) also from Germany and on that particular car forum, many have had this same issue of the underbonnet lining/insulation missing from some and not on others

Lucky for me it wasn't missing on either one, some people actually like the fact it's not there, because they think the extra heat retained by it is not a good thing :iono: personally I like the sound proofing it provides and if it's meant to be there and your paying for it, then it should be included.

Some of these Euro manufacturers need top get their act together and provide the vehicles complete with everything that's supposed to be there, especially brands like BMW whos vehicles are at premium costs to buy

Yes I agree, seems to be totally random as to which car have them. Its as if they put insulation in on every third car or something on the production line.

Im lucky, I got one.:thumbup:

be interesting to see if corey got the insulation or not, his was next on the production line after mine.

I just picked my car up today and NO insulation!

**BUMP**

No sound insulation in my new 120d..... very weird.
(hence why I'm going to buy the one Andrew@SBM has if it's still there )

No insulation on mine either -- mine's a late Jan /early Feb 09 build

BSM 135 manual built 4/09, NO INSULATION!

[sparoz]

120d - has insulation, 125i, and 135i no insulation. Remember I had Dunlop runflats on the 135i and Bridgestone on the 125i.

This would have to be one of the most inconsistent hit and miss part on the 1er with no real answer why..
There have been polls on the other 1er forums since mid 08, and the results were allways inconclusive..

No insulation.

135, 4/09 build, manual, sunroof, no nav, bridgstone tyres.

[CT135]

No insulation.

135, 2/09 build, manual, no sunroof, pro nav, bridgstone tyres.

[sparoz]

Sounds like the later builds don't have insulation.

[Zuzu]

Correct...Seems as though that BMW had dropped the insulation completely from the MY09 cars..

Why would you want sound insulation on the 135 anyway?

..You could argue that it keeps the engine cool in summer or warm in winter from the outside elements...

Or...To keep help reduce engine noise,,

Will the heat generated by the engine have any detrimental effect on the paint on the bonnet?

i don't have the insulation, and one thing i noticed is that when it rains i often see steam coming off my bonnet when i'm stopped at traffic lights... it's a little concerning. Preservation of the bonnet paint is probably the only one reason why i'd want to have the insulation.
