The Series 1, Series 2 and Series 3 XJ saloons were all equipped with the same climate control air extraction system including the Air Extraction Tray (Jaguar part number BD37528) with the flaps that produce the “cow bell” sound when the material fails and metal to metal contact occurs. I suspect that your Series 2 has one but you just haven’t seen it because it is located right beneath the rear parcel shelf. On the Series 3 cars it is covered by an insulated fiberboard painted black. If you open your trunk and look through the small holes in the trunk lid opening at the front of the trunk lid, you will see the flaps.
If you haven’t experienced the cow bell problem, a prior owner must have fixed the problem before you got the car. Many use the quick method with sealant or spot ties (I have seen both) to keep the flaps from hitting the tray. Others have done the more laborious method of removing the extraction tray and removing and replacing the flap material or something in between. I own and drive three Series III saloons and I fixed the cow bells in each of them to eliminate that annoying “jingle, jingle, jingle” sound when closing the drivers door when the other doors and windows are all closed. I used headliner material and adhesive to resurface the flaps.
Attached is a picture of one of the air extraction trays that I removed, repainted and repaired the flaps before I reinstalled it. The flaps that produce the “cow bells” are in the tray circled in red. There are two small flaps in the Series 3 saloons that can also produce the cow bells sound, they are visible with the forward trim removed. The second picture shows those two flaps, located on both sides of the sunroof motor, also circled in red.
