Hi Volvo
I have a problem with my 2012 s60 T4
I think it's quit famous , the "reduced engine performance" error
while depressing the gas pedal it gives minimal power and the car doesnt respond..then i got that message.. i stopped the car and turned it on again and it was ok ..but after trying to acclerate it happens again
I visited the local maintenance twice and it wasn't fixed , disappears for couple weeks then comes back
I read online that it's about etm system or maf system , Can you tell me further information ?

 

by local maintenance i take it you mean the dealer right? keep taking it to the dealer until the the problem is fixed. its part of the manufacture warranty that the car comes with.

 

yes . i mean the dealer . i think they can't diagnose the problem . that's why i am aking here for help

 

Just purchased a 2011 C70 turbo two weeks ago, 24k miles. It shut down while driving on the expressway last night. Lucky to be alive today!! The car is at the dealership today. Hope it NEVER happens again.
