Replace the fuel line on duster as getting bubbles in fuel line. Wasn't a bad job inner wing cover moved out way to access filter remove the expansion bottle to remove old pipe and refit new pipe 36quid for pipe put all back primed the bubble pump wasn't expecting the car to start but it did so all work so going to get back onto TA.
Got a abs sensor to change on a vw toureg .went to change it wheel of went to remove caliper but it's not a bolt not a Allen or a torch bit it's a spline bit didn't have one so ordered a brake spline caliper kit looking at kit saw a socket with a 5 sided head very strange looked into this thinking faulty kit but no the do 5 sided bolts on Merc cars what every next
so hope this helps others kit wasnt expensive either ,
must be main dealer only to get new olts if you needed one or just change to normal bolt once out high tension a1 or a2 i presume
Also pentagon Allen keys as well
