I have a 2000 S80 T6 Volvo and I think the turbo/s may be going out or maybe it has to do with the coolant level. there is a message on the instrument panel which says coolant level low, stop vehicle now (or something to that effect). If the turbos are cooled with coolant and the level is low, seems I need to do a flush and bring the level back to a safe volume. Would this be right? Oh by the way, the car has 212K showing. The reason i think the turbos are failing is that occasionally when i accelerate, i feel a surge and hesitation at the same time. Also I noticed when I went around a corner at a normal speed the cars RPM jumped to around 3k, then back to normal after going thru the turn.

 

u r having a multipe faults.
-always drive w/the proper level of coolant no matter what. u may have a leak somewhere, check it!!
-the surge & hesitation could be the turbo control valve due to carbon bulit up inside or maybe an engine problems
-the RPM jumped could be a sign of your transmission need service or starting to go
