Erm I'm no mechanic!
Just thought I'd put that out there and I managed it, in fact it saddens me to say it took 45mins to get the clip off! It was an absolute pain. Once off I had the DV out in 5 real easy. Probably took 5 to pop it back in however I did buy tools to do the job:
A 1/4 socket wrench
5 Allen
Extension for the above (made poppng the top screw back a cinge)
With regards to location it's off centre towards the drivers side kind of right under the engine, Google it there are a few guides are out there. You should be able to see the part number on the bottom visible when your looking up.
After research I went for the revision G, but if your running more than stock perhaps D its a bit stronger although there is opinion either side on this one!
Top tip: open your bonnet for some extra lighting 😊
