Tested and fully working ECU for the 2.1 injection engined vw transporter T25/T3. These are mounted in the engine compartment of late T25 Busses. This one came out of a late model syncro, and i have tested it by running it on my own syncro and it works fine. Hard to find if you need one. Any questions please ask. Photo`s show the actual item for sale. Will send on a next day service fully insured.
