I'm new to the forum but I've had an 1998 S70 T5 manual since 1999. Great car in many ways. I suspect the ECU is acting up so I'm looking for a replacement. Please let me know if anyone knows of a reliable source for these. Bosch number is 0261204450. Thanks.

 

CAR-PART.COM is a good source to search for a local yard. Generally ECUs don't go bad - so I'm curious why you think its acting up... More commonly there can be issues with connectors, ignition switches, relays (including those soldered into the the CEM (central electronic module) and the various bits of plumbing.
