Few problems: - Most independent shop does not have the OE Volvo diagnostic equipment, like VIDA or DICE and many other generic diagnostic computer fails to correctly identify and translate OE Volvo diagnostic codes to OBDII codes, therefor the technician won't have the correct code to work with. - Many times aftermarket electronic parts just won't work. Especially when shops are using a generic, "works on everything" parts. I'd suggest to get the OE parts. - Always ask for the diag. trouble codes. You paid for it, so they should give - better to print- the codes for you. We really need the DTCs to help you. My guess is that the shop misidentified a fuel trim code for an O2 sensor problem, but it's just a guess... I'd suggest another diagnostic from a different shop and let us know the codes so we can help you more. Zee

Hi, To better help, we need some more info. Can you provide us with the code that they pulled from the engine control, the parts used for the repair and was the shop an independent or dealership? Thanks!
