turbo problem?

[simc]

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.

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 ...

Thanks clan

Have checked all hoses- seem to be secure and tight. As far as i can see from above.

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.

hi

not sure of the engine type, but it's a 163bhp on a 52 plate

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?

[simc]

OK..

time to show my ignorance.... ECU?:hissyfit:

[Viper_7]

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?

it sounds to me that the car is in safe mode u will need to reset the ecu

im sure some one on here can tell u how to do it i cant rember the code
basicaly it shut every thing down just so u can limb the car home so that would be my gues as the fault on no boosed

It's the sudden stop from a high speed that has been known to cause an overheating problem with the turbo.

I think the safe mode tip could be good one though.

interesting thoughts, guys.

There is now no warning message in the car. It ran through from "low coolant level" to "stop engine", at which point she did.

As for the turbo, i used to hear a whistle as it kicked in. Now all is silent...

Safe- mode interests me (very Volvo). Can the ECU be reset simply or do i need a specialist electrical diagnostic service?

im not sure how to reset it on ur car but u could try puling the batery cable of over night that wont hurt as long as u have the radio code it some times workes on older cars

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.

hi
normally for just the dtcs read it wont be too expensive , its what they find and if you want them to repair your car that costs the months wages,

Hi all

as promised i can now feed back on the result of the S60's trip to the main dealer. They quickly identified, through diagnostics, a fault with the air mass sensor. This was replaced within a day. They attribute no blame to the local garage who carried out emergency repair work (see thread). It was ,apparently, a coincidental failure. They then relieved me of £465. How does the price sound?

Anyway, it goes like a bat out of hell again.
Cheers

hi
glad you are now back on the road, if you would have known it was the maf sensor you may have got it cheaper elsewhere but imho you cant beat original.
