I was driving on the freeway going about 65mph yesterday. In an blink, I noticed a shift in the speed in the car, going down gradually and noticed the "reduced engine performance" message on the message panel. The car speed went down to about 45mph and held steady until I parked the car. About 35/40 minutes later, I started the car and noticed that the message was not there. I continued to drive home - about 10 minutes - and the car seemed to be okay. I drove to work today, going about 35 to 45 mph and everything seemed okay. I drive at lunch time with about same speed and no "reduced engine performance" message. Should I be worried? Is it dangerous to drive the car? Also, do you know what would cause the "reduced engine performace" light to come? What is the problem(s)?
Thank you,
Beboop

Hi Beboop. Im in South Africa having just bought a 2005 S60 2.0T . After about 1000 kms it suddenly shows the reduced engine performance message and the emission sign is on. My engineer here who is non volvo but pretty good says it 'needs a computer check by Volvo which with the following work they suggest here can get very expensive'. Before I go that route i wonder if you ever got that resolved and if so can you give me any pointers please? John W

I don't have my Owner's Manual handy; but I think it outlines a few of the reasons the "reduced engine performance" message is rendered. Meanwhile, you could do a quick search on this Forum and see that it has been discussed here before (I think). If I can find it, I'll come back and post the link.

I've had it myself; but don't remember what the exact cause was . . . . which must mean it was somewhat minor.

Here's that link to a prior discussion:

Reduced Engine Performance

You'll note too that one of these participants provided another link to an even earlier discussion.

My own encounter with the "limp home mode" may have been before the ETS Upgrade/Recall, as I would remember it well if I had to spend a lot of hard-earned money.

there is a you tube video showing how to clean your throttle, due to carbon and gum build up, you need to remove the throttle ,it has 4 bolts you need to remove from the bottom of it,but watch it on you tube first.

Right, you need to get the Engine code to read, there are 3 ways.

1- Indicator stalk
2- Any ODB scanner
3- Vida with Dice [expensive one]

1) Here's something you can do quite easily to check for any stored DTCs (Diagnostic Trouble Codes):

DTC readout:
* Press and hold "READ" on the indicator stalk
* Press rear fog light button twice, in rapid succession
* DIM-screen will list a readout of DTC codes (skip through by pressing READ)

Some of the categories will show "Checking" but may never update, this is not necessarily indicative of a problem. The message "DTC SET" however, indicates a fault-code has been stored for the component mentioned.

Sit in the car, ignition on, press and hold the read button on the indicator stalk and then quickly flash the rear fog light on and off. You'll then be able to keep pressing the read button and scroll through each module individually and the car will tell you weather that unit has any dtc's stored, but it wont tell you what they are. Defo a good thing to check thou before buying one and getting the seller to sort before you buy

SET means there is fault code stored,CHECKING could mean the same.READY means no fault. DTC's are Diagnostic trouble codes.

2) Any ODB engine reader will do from eBay, install on your android a odb reader, enable bluetooth on your mobile, plug the ODB plug in car, drivers side, little flap, with ODB written on it. The application on your android phone will give codes, for example P0244 then all you need to do is translate that to the corresponding ECM error and bingo you know the fault, solving is another issue ;-)

3) Buy a Dice, get Vida 2012A and do it yourself.

Have fun.
