Hi all:

I've had my 02 mondeo tdci for just under a year now. She's ran like a dream until now.....

recently I've been hearing a hissing sound during acceleration but with no loss of power.

However tonight as I was driving home I noticed a massive loss of power (as if the turbo had gone).

The hissing sound is now a lot less audible (if its there at all) but am hoping it's just a split hose and not the turbo itself.

Any advice would be appreciated.....

Thanks will :)

check the intercooler hose on the bottom of the egr valve it common for them to split and would give the symptoms you have.
