Can someone tell me what is this part under my trunk lid? (See picture)
It made of rubber and seems to be deteriorating.
I can't understand the purpose of this part and what is the part number?

 

 

Buffer: A211 750 00 97 (source: EPC)
Note reads: Please refer DTB-B-88.50/74 before replacing this part

 

What is the purpose of it? What happen if I don't replace it? I didn't notice any issues opening or closing the trunk.

 

I would guess to keep the trunk lid perfectly aligned.

Looks like they are cheap

DTB install instructions:

Pull buffer outwards in direction of arrow
Close and reopen the trunk lid
Push buffer two notches inward and then tighten to 4 Nm

Just replaced the tubular frame gas strut on the battery side in the trunk. 2009 SL550.
Got one from FCP Euro "Mercedes Trunk Lid Frame Shock" SKU: STB-9961UO
"Mercedes Trunk Lid Frame Shock - Stabilus 2307500136
SL500, SL55 AMG, SL550, SL600, SL63 AMG, SL65 AMG"

Replacement took ~5min. Flipped the trunk lid back (by starting roof opening sequence..) without putting the trunk lid in the high up service position...then from the side of the car reached easily in to unhook the metal clips on the top and bottom...
New gas strut can be pushed in with just a little bit of pressing on the ball joint connector.
Done.

 

You have an SL550? This is a 211 forum, my 2006 E320 never had a gas strut in the trunk.

 

Hi would you be able to post a picture of the loation of the strut and also ne showing the position of the trunk lid for changing the strut. Many thanks!
