So I was wrong. Nothing came loose, but they fixed two coils and a fuse. Now I get the car back from the shop running with vibration and loss of power to the pedal; it's just loud and pants everywhere it goes. The warning lights stayed off for about 15 minutes. It still runs and drives and the RPMs seem fine, but they just covered up the problem because it's not the same as before the problem happened.

We're pretty sure it's not the ETM, every line is connected and clean (that we know of) and the engine mounts are on solid. In addition to the original "transmission service urgent" message, I now have the following:

Emissions System Service Urgent
Drive Slowly, Service Urgent
Coolant Low, Stop Safely ASAP
Transmission Service Urgent
SRS Airbag Service Urgent (on since before the problem)

So basically, I've come to the conclusion that the car is haunted. Any suggestions?

 

Take it back asap.

 

back to the shop or back to the dealer? lol (but not really)

 

Who ever just said the car was fixed.It only took 15 minutes to throw codes again.

 

yeah, i'm not driving it around, i'll take it back soon though. Any ideas on what could be wrong?

 

Sorry but not really without seeing all the codes that are stored.

 

Yes, tech is rite, get the codes pull out first then only we will know whats the actual problem...all the best.

 

There's an extensive list of codes, the most important thing to mention i guess is that all of my cylinders seem to be misfiring. It's not the ETM, I feel quite foolish but the spark plugs may all be bad, because the rest of the list is electrical signals that are too low, etc. Should fix a lot of the codes, what could the misfiring be about?

EDIT: Here's the full list of codes

CCM-0003
CEM-2E03
CEM-6A01
CEM-6A03
CEM-6A04
CEM-E000

DDM-0006
DDM-000A
DDM-000D
ECM-530D
ECM-261A
ECM-262A
ECM-272A
ECM-280A
ECM-2B0A
ECM-2B2A
ECM-3502
ECM-3503
ECM-3512 (misfire cylinder 1)
ECM-3513 (cylinder 1)
ECM-3522 (cyn 2)
ECM-3532 (cyn 3)
ECM-3542 (4)
ECM-3552 (5)
ECM-3562 (6)
ECM-4308 (major leak?)
ECM-902A (throttle unit signal low)
ECM-903F ("")
PSM-0034
PSM-0035
PSM-E003 (configuration fault)
REM-4A31
REM-4A35
SRS-E003 (configuration fault airbags?)
UEM-0004 (siren communication fault?)

 

umm is that even possible to have so many codes at one time ?

most of those i bet are ghosts, triggered by one another, could the etm be bad ?

 

What brand plugs are in there and how old?

 

Most of the codes are for "driver side lock- signal too low" or something like that. I really don't care if all of those random codes stay there, I know they don't mean anything. I have bought new plugs that fit my car, and they will be put in this weekend. I am also thinking maybe new sp wires and I am curious as to what the condition of my fuel filter is.

 

You do not have plug wires. You have the coils.

 

yeah, realized that when we put them in. Still didn't do anything. Bad ETM?

 

It is possible but I would have to see the codes if any are stored to see from there.

 

When the dealership gave me the codes, no faults were found for the ETM (which they're pretty much paid to say).

Maybe a bad ECM? If I can't figure out what's wrong and fix it, I think I might resell this car.

 

Nothing in the ECM either?

 

the ECM pulled up many of the random codes, as well as all the misfires. I really wanna find out why i'm misfiring on all cylinders. I think if I identify why that is happening with that I can go from there. I really wanna know why this car is one big rolling computer as well, my 960 didn't have nearly as many modules/computer systems as this car. It seems like they were a problem the first couple years they made the S80.

 

First, let me admit that I'm new here and I haven't done my research.

I just got back from the Volvo shop with many of the same codes/symptoms that the original poster is having -
1. My car run horrible right now, I replaced the plugs and checked the coils.
2. I started with a Service Emission System error, but after leaving the shop, a transmission error came up.
3. I have whole page of codes. The repair guy led me to believe every system in the car has (or will) fail.

After reviewing the codes, I think the most significant are the O2 sensor codes.. i think i'm going to replace my O2 sensors, but it looks like they're $200-$300 each.

For the record, out of my ~40 codes, the O2 codes i have are ECM-280A, ECM-290A, ECM-2B0A

Just adding my 2 cents...

 

what year is your car? My mechanic didn't tell me my car was gonna fail, they just said it's probably a bad module, but we don't know for what. Most of the codes are ghosts i'm sure.
