As these can be fragile can anyone tell me the safest way or wrinkle you have worked out to remove the maf plastic cover. I need to get rid of that K@n in there and put a Audi paper element in.

Cheers.

AAN MAF Cover with PNs and Photos for removal hints

As these can be fragile can anyone tell me the safest way or wrinkle you have worked out to remove the maf plastic cover. I need to get rid of that K@n in there and put a Audi paper element in.

There are two large pivot sockets on the fender/wing side of the cover and five gripper teeth on the engine side, as shown below. It's the engine side gripper teeth that break off due to becoming brittle with engine (and turbo/downpipe heat). I think the strategy is to stand beside the fender/wing and pull the cover towards you and lift up *OR* push the cover towards the engine and then gently pull up the gripper teeth. (Is it even necessary to remove the cover to remove the top of the airbox? I don't think it is)

Item 2A here:



Here is the front of the cover (this is a new one from my hoard):



Here is the back side of the cover, showing the two large pivot "sockets" on the fender side of the cover and the five unevenly spaced gripper teeth on the turbo side (where they bake in the heat and get brittle and break off over time)



Here are the gripper teeth from a different angle:


Here is the PN on the back side:



Good luck. Try to remove the airbox lid without removing the MAF cover first.

When looking to remove the dress up lid cover from the top half of the air box, wear gloves two pairs of mechanics gloves to protect the tips of yor fingers and nails, while still allowing you to exert the necessary pressure to be able to 'peel' back the lid starting from the engine side as Dave has explained. Once the five teeth are released all at the same time, the lid comes off in your hand.

Also, do when the engine has just finished decent journey and stood for five minutes to allow the ambient heat of the engine and turbo to soak into this lid to make it more flexible.

Even when new if you look to take it off without fully realising how it attaches you'll crack it. BTDT. You'll fully realise how it works when you get it off, ideally without cracking it.

On my current one I used a file to file the teeth on the lid a small bit to simulate a bit of were to allow it to be taken off, while still allowing it to be tight when fitted.

Worth getting this lid if you don't have one on your UrS6. It make a huge positive change to the aesthetics under the bonnet.

Notwithstanding all of the above, the cost of new lid is still worth it, imho.

Ot you can velco the cracked one back into place.

Thanks Dave and Macspring for your super stella info as usual. I ordered an air filter from Audi today so fingers crossed it will be there tommorow ready for the Scottish tour. The guy i bought the car of "Moggies" on here actually only just bought a new cover from Audi a few weeks before i bought the car so it won't be brittle yet!?!


Cheers guys!!
