At recent MOT on my 1988 G Wagen the inspector noted that the under bonnet insulation was falling apart stating it would be a failure next year under new rules. I had already contacted the local Mercedes dealership who were unable to assist. Does anyone have any suggestions please?

Re: Under bonnet insulation.

Lots of products from different suppliers available online. Also youtube videos available for how to do the job (although it's pretty obvious).

JUst google "under bonnet insulation"

Mine isn't bad enough to need replacing (yet) so haven't tried any to be able to recommend.

I'm sure someone will be along in a while with a recommended product.

Re: Under bonnet insulation.
I used the aluminium sheet that is used behind household radiators to direct warmth back into the room. It is simple, tidy and easy to stick on and only costs buttons from B&Q. (Other DIY stores are available.

Re: Under bonnet insulation.

Isn't part of the function supposed to be sound insulation though?

How effective is the radiator foil at that?

Of course, some people like to have extra grunt - but having had a "sports straight through exhaust" in the past, I found that it can become quite tiring especially on motorway driving.

True, Mark.

However, the OM606 does sound good.

Ha! Ha!

Re: Under bonnet insulation.

Thanks to all for their input but since G Wagens are still produced in Germany I was hoping someone knew how to purchase replacement under bonnet insulation from Mercedes when the local dealer is unhelpful. I want mine to remain as original as possible. I have investigated online but not found a similar product as used by Mercedes. Maybe I’ll have to travel to Germany!

Out of idle curiostey is your a Petrol or Diesel?

Secondly, is insulation no longer available or is no there no stock in the UK? I have some quieries on going with Austria; I could enquiry from there but you will need to furnish the full chassis number.

Re: Under bonnet insulation.

Thanks to Pistonheads input. The car is petrol driven and Chassis Number: WDB46023827058977. The local Mercedes Dealer in Southend-on-Sea said there was nothing available on their database. I pointed out that G Wagens were still being produced but was informed that since new models were not sold in th U.K. they were unable to assist.

Re: Under bonnet insulation.

Unfortunately that's the calibre of people that some Mercedes dealers employ to staff their parts department.

Perhaps what he meant to say was that since very few people could afford to buy the new models they were not able to assist. Funny though that they are currently advertising the new G on their website.

Maybe you should try a better dealer - you could try chrisearl@sytner.co.uk. He's been helpful in the past. Email him your Chassis Number and a description of what you want.

But I'm sure many other dealers would try a bit harder than Southend.

Re: Under bonnet insulation.

Hi, fourbyfourclub.com have the OEM under bonnet insulation, it's not cheap! If you go onto their website, 460 body parts page six of six. I also assume it's LHD so not too sure if that would be compatible.

Re: Under bonnet insulation.

hi there,

I have just finished restoring my W463 SWB petrol 300GE

I stuck the black sound deadning panels to the underside of the bonnet to increase sound insulation

and then used the old sponge cover as a templale for the fireblanket used in racing which is a woven

blanket with the aliminium silvered on one side .

all round an excellent solution.!

The panel you require is def available from mercedes benz dealer on order - from memory it was very expensive

(£176??) just need to make sure the parts guy knows you have an old vehicle -some of those guys

were not born in 1992!

 

can send photos if of interest

Re: Under bonnet insulation.
Many thanks for all your suggestions. I did send an email to Chris Earl at Sytner but no response has been forthcoming. I will try again with other Mercedes dealers and perhaps will have more success. I much appreciate the diy solution but I am uncertain if this will fulfill the new stringent MOT regulations coimg into force next year. Christmas greetings to all.

Re: Under bonnet insulation.

My understanding from someone who knows everything there is to know about G Wagon spares is that MB no longer do supply the under bonnet sound insulation for the 460 model. They do for the 463 although he was unsure if this would be a perfect fit for a 460.

I can't imaging that you would experience any problem with the MOT if you were to use something made for the job but not by MB (they probably wouldn't be the manufacturer anyway):-
