Need to fix some holes i made above the silencer, through the insulation - BMW Forum

528i_tourer · 08-28-2009, 07:08 AM

Well guys i have a problem in my car...i wanted to put some screws and so i made some holes in here

(this is above the silencer (silencer its ok, no holes in there!), where we use to put the CD player) and things went wrong...i made a hole in the thermal insulation too....by mistake...

its part number 12 on the picture above...

Now i need to fix these....i hope it is possible to fix like it wasnt there.....

I went to BMW dealer and they told me they could fix it soldering or welding (which one is the right term ??) the screws and the insulation since there is a hole in there they could also provide the needed resistance to the screws through the insulation

I am very very concerned with these stuff but i believe it can be fixed, am i right ?

My concerns are with the holes i made and since there is the silencer in here....would it be some gases from the silencer inside my car or could they insulate these and no problem ?

Can you please help me cause i am very worried with these thing....i guess it could be fixed without any problems in the future but....

Also, what kind of screws can i use in here since there will be a soldering /welding in here ?

Thanks a lot for all the help you could give me!

You may want to consider a good fix. Simple filler may fall out over time.

Well then soldering/welding would be better of course, is that what you mean ? I mean just filling with anything wouldnt fixed of course.

The insulation prevents the gases from entering inside ? And if there were any kind of gases would i notice them too ?

Thanks a lot!

Yeah, a welding fix would be better. Exhaust gases may tend to get in there among the turbulence behind the car.

Sorry to insist, but you mean that a welding fix will avoid gases of entering inside of course...sorry for insisting but i am really concern man and these is getting me worried!

I think the exhaust concern is secondary to a good fix that will prevent corrosion issues from developing.

Now you left me confused

Corrosion problems from holes ? What ? Thanks again for your patience!!! I am really thankful for your explanations!

Are the holes through metal or plastic? If the former, the holes have exposed unpainted metal.

Through metal as you can see on the pics above i made the holes on metal, right ?

It looks that way, and would be why the dealer spoke of welding.

Hmmm....let me see...i start to understand something...welding its just to prevent corrosion on metal ???? And the insulation stuff??? Isnt that a concern to have ???? I really dont understand how these works....so welding would prevent corrosion but gases problems arent the main problem ???? Why ??? (living and learning!)

THANKS!
