One of the lower battery box, cover retaining tangs on my 2005 3.0 Sovereign is broken, and the engine lacks the plastic cover I've seen on other X Types, so, finding myself near a local scrapyard I set about liberating these items from a silver X type 2.5 that was down on its luck. I easily removed the parts, and also helped myself to a set of 5 wheel nuts which had been left under the bonnet. I also wanted one of those boot opening assisters but the boot on the scrapper was shut and there was no way of opening it. When I got home I found that there is nothing to secure the engine cover onto - al all three locations. Also, the battery box is a different size being about 1cm shorter - and that after disconnecting and removing mine. Very disappointing and a waste of time and hurumph....£5. Sometimes you just can't win.

Sorry to here that your trip to a breakers was unsuccessful. I note you comment about this engine cover for the V6 engines. I assume this is the one that sits over the front cylinder bank? Was this only fitted to certain years or models? My 3.0 sport premium doesn't have one but I've seen them on eBay for sale. But looking at other cars on eBay it looks like this cover is very rarely fitted?
