Ok cheer. It doesn't run at al. Not even when really hot so I'll have to get it checked out..
Thanks again

Hi all.
I have a 2001 s60 2.4t petrol. It seems to me that the radiator fan is not running at all even when very hot. Thermostat stays ok temperature sensor is ok and new.
I've checked wires and connection and what I think is the fuse but not sure if it is.
My question is this... Where is the fuse ...

Well no good. Ok when it's running normal a little bit better however still losing boost when hot. Next step is diagnosis at a cost. I may even check for common split pipes but I really don't think it is that as it boosts fine until it's really hot. Will keep you posted

Well I put it in this morning and drove about 23 miles and I have to be honest and say it does seem a bit more responsive. It got to full temp ok and didn't stutter once. However I'm not holding my hopes just yet as I didn't really get stuck in much traffic. I shall see how it goes over the next day ...

Makes it harder with no error code though. Even when it's at its worse.
So today I got a bottle of cataclean it's got good reviews and defiantly a cheaper option for right now to see if it does help for a short time at least seeing as I been quoted between 240 and 500 quid for a cat. I shall let ...

I have exact same problem, mines OK when cold but as soon as it gets to temp boost goes and it sounds a bit like a "Waarrpp" sound (think thats how you spell it) almost like the control valve is letting boost out from wrong place, can't see any leaks in intake/hoses and my stfc & ltfc indicates no ...

Hi guys.
Right code reader came and nothing no codes at all. The app for it showed coolant temperature at -41 so got a replacement and still shows -41. Not been out long enough to see if I still have an issue as yet. The wires for the coolant sensor are fine if I unplug it I then get a code. Plug it ...

Just a quick update while I'm waiting for my code reader to come. Got home tonight and the engine wasn't boosting again. So left it ticking over and disconnected the maf and unsurprisingly the engine cut out. So I left it unplugged and tried to start the car and it started straight away no problem ...

Cheers I'll look into it

Might have to get a code reader then. Any recommendations on a cheap basic one
