Advice on reduced engine performance 2014 S60 D4 engine

[Engineer254]

Hi all,

I just bought a nice 2014 S60 - with D4 engine in very good condition from a private dealer. however after only 3 days of owning it I have got the turtle engine warning error 'reduced engine performance' and the engine warning light with CHECK written underneath

from what ive read this error can be anything from a faulty fuel filter to a problem with the turbo, the car is under warranty so I could get it seen to be the dealers mechanic however im worried that they might try to temporarily hide this error instead of fixing the problem (not a well known or large dealership). should I take the car to my local garage to see if its a serious problem first? or should I just staight up ask for a refund ? the car has done 120k miles.

not sure on the best way to proceed

thanks all!

Take it back to the garage you bought it from and get them to diagnose the fault. Only then can you decide what to do. Now you've logged a fault under the warranty, it should still be covered if they delete the code and it reappears later.
