Default T4, coolant leak from back of engine.

Hi all, one week on the road and she's become incontinent already

Pulled into the works carpark this morning and backed into a space, noticed a trail, yep, coolant, it appears to be coming from somewhere along the back of the engine, as it's running out from around the driveshaft / factory lower strut support area, any quick things to check on before I begin to cry, I'm praying it's just a leaky hose of some kind.

Many thanks in advance

Found it!

It was a roughly 4 inch long piece of coolant Flexi hose that goes between the hard pipe on the coolant rail at the back of the engine and the 90 degree hard pipe that's attached to the turbo with a banjo fitting, access from below is impossible, access from above is not much better.

Firstly you have to fit and secure the rubber hose to the 90 first with a clip before you do anything else because you can't access that bit to tighten anything up in situ, the jubilee clip also has to be at exactly the right angle otherwise it will foul, you also can't attach and clip the other end of the Flexi to the hard pipe that's bolted to the back of the engine and then put the banjo fitting back because the pipework is all shaped and the angle is wrong.

You also cannot attach the banjo end first and then push the other end of the Flexi on because there isn't enough space to do it, unless you can somehow bend the small piece of flexi in half and then pop it on from a funny angle, certainly not one handed, possibly with both hands but there's not space to do that.

The only way that i could find to do it was to push the Flexi on by the tiniest amount so it won't fall off, then loosely attach the banjo fitting, then manhandle the Flexi on a bit further, then tighten the Banjo fitting, then wrestle the Flexi on all the way, and finally tighten the clip on the Flexi, the clip that you've forgotten to put over the pipe, what a f****!

Trying to place, one handed, the aforementioned hard pipe with banjo fitting with the bolt in it, the sealing washer, and the Flexi with a jubilee clip slipped over it, without losing either a sealing washer, the jubilee clip, or both on the way into position is not an easy task.
