Default turbo problem?

Hi all

First post here so grateful for advice. S60 D5 89,000miles broke down with to coolant loss due to perished/split hoses,(wife stopped when warning message came on). Car recovered to local garage who replaced the coolant hose assembly, O-rings etc. The car now runs rough and has no power. There is no turbo "kick" at all. Took it back and they tightened the hose from turbo to air box, which made a small improvement, but car is still only 60% power. They say it is a coincidental failure of "something else" as they only removed coolant hoses and the turbo hose for access.

so....

Could it be something simple (EGR valve/ O2 sensor?)
Could the very temporary loss of coolant have lead to turbo damage?
Has the local grease-monkey got in out of his depth and screwed up?

Please send advice/ ammo for Monday's "where do we go from here?", meeting.

Cheers!

sounds like they may have taken a turbo hose off and not put it back properly and it has blown off with the pressure ... perhaps ...

Which engine and year is it? Later ones have the turbo cooled by coolant to protect it from damage after driving on the motorway and stopping suddenly for some reason. Like to get fuel or because you've got a problem.

It's an early one then. So no cooled turbo unit. It is possible it got damaged when you lost coolant, they are a bit vunerable to heat under certain conditions, hence the introduction of the cooling.

Looks like you may need to do some investigaing to sort this one. What does the ECU say?

ECU = Electronic Control unit. there's actually several of them, but think what is meant is are there any fault codes showing.

Unless your wife was booting it, you shouldn't have any problems with the Turbo regarding over heating.

I'd still be inclinded to check the hoses again.

When you say your down on power - do you actually hear the turbo pick up?
or is there just nothing?

hi
before you spend any more money on anything else get the codes read, either by an indi or at a volvo garage, then go from there, at the moment its all guess work,.

thanks all

I have booked the car into the main dealership (nothing until 9th Oct. and no courtesy car!) and am arranging to have next month's salary paid to them directly.

Will let you know the outcome in a couple of weeks for the reference database.

Cheers
