LHS looking from front? = Fuel Cooler

BS226 Viton orings will fix it (from CBC etc)

Remove the acoustic cover and you'll see a cylinder shape...

Sorry its the passenger side of the engine.

Check where the bottom of the top radiator hose connects, it may only need the clamp replaced with a screw type hose clamp, those spring ones loose there tension after a while.

Check the whole hose too

If it is the LH side towards the rear, it sounds like the oil cooler.
The cooler can corrode the nipple where a short hose joins.

That is what happened on mine. I had had a slight leak the day before but
couldn't find where it was coming from, then next day it dropped all the coolant.

The cooler is not cheap from a dealer.

LHS at the rear could be a heater hose / bypass hose. Tucked down behind the turbo.

Thanks all. I'll have a look in behind the turbo in daylight tomorrow and post the result.

I hope Big Jon's right, that is the cheaper option.

Phil 633 wins the prize. Its the short hose into the oil cooler. How did you fix it. It appears to be the hose that is perished.
