1999 S80 T6 Intermittent Trouble
 

The other day my wife was driving the S80 and all of a sudden the car wouldn’t accelerate….she is able to get the car home. When I get home from work I plug in my pocket scanner (Actron Pocket Scanner Cp9125 Obd2 II Code Reader) and it says no codes. Also the car has no check engine lights on at all. I have had the ETM replaced last year with a Xemodex unit…(the first unit they sent me was defective according to the Volvo dealership it wouldn’t communicate with the computer) so I called Xemodex and explained the situation….they promptly sent another unit to the Volvo dealership and I paid to have it installed…no more problems with the ETM.
This trouble comes and goes…. sometimes I go out to the garage and start the car and it will rev up in park or neutral no problem….other times it won’t seem to rev at all maybe 1800 RPM. This problem will also happen when driving down the road. One second you will be driving down the road just fine and then you will press the accelerator and the car won’t accelerate even though my foot is to the floor. It won’t go more then 30-40kms then maybe 10 minutes of going 30-40kms I will get power back and the car accelerates like normal

Any Suggestions?

It ended up being another defective Xemodex ETM my second defective unit in less than 1 year.
