Still in Limp Mode

Hey All. I have a 2000 S80 in limp home mode. No codes on OBD II. I've replaced the MAF sensor. Then took it to dealer. They scanned and said it was definitely the ETM. I sent the ETM to Xemodex for rebuild. Car is still in limp mode. Battery is good. It's actually worse after ETM rebuild as it will stall out now. Is there a computer reset that needs to be done? I had battery disconnected while reinstalling ETM. Any help would be appreciated.

I had major issues with my S80 being in limp mode until I switched the O2 sensor connectors. Not sure this will fix your car though.

The computer resets after the battery has been disconnected for awhile. If xemodex failed to fix your etm then you should probably contact them. Get your car scanned again, if you're still stuck in limp mode then there must be a code associated to that.

What codes are you getting?
If its transmission maybe its the speed sensors. If its a O2 sensor issue put some zip ties on the connectors to bring them together tight.
Thats what worked for me
