Back in june of 2008 - on start up my 99 volvo v70 - would rough idle, rev to 4000 and would not exceed 20 MPH. The idle sounded like sneakers in a dryer. I took the car to my garage and was quoted $2000.00 to replace the etm - I was told by my garage that the etm may still be under warranty. After speaking with volvo USA - I was advised that this part was under warranty and I should bring to the nearest volvo dealership. I did. Boston volvo village - did a software update and after that reported no issues with the etm - they claimed cracked vacuum hoses were the problems. They replaced the hoses and return the car. The car broke down a day later - rev to 4000, rough idle, won't go over 20 MPH - sneakers in washing machine sound. I brought the car back to boston volvo village - this time they told me that I had an bad accelerator pedal - which was replace cost was $225.00. The car broke down a third time - this time on a busy highway - I was able to pull off - but if not for some excellent driving by others on the road there would had been a 3 car pile up. Boston volvo village towed the car back to their garage. One of their employees admitted to me that the emt was the problem - but that volvo makes it impossible to replace the etm.
