Title: MK3 ECU's Post by: VwGuy1010 on April 23, 2020, 11:43:26 AM Hi,
I'm trying to figure out what generation of ecu's were used in the mk3 OBD II era. My brother swapped a 97 Passat vr6 into his golf, along with its ecu, a few years back. I can't get a hold of the ECU part number as the car is in storage. Been searching online for the past week and can't seem to find a definitive generation. Any info would be greatly appreciated Thanks JB Title: Re: MK3 ECU's Post by: matchew on April 23, 2020, 12:06:59 PM 021 906 259 ?? if its an American market car or 021 906 256 if its a Euro market car.
USA is quoted as M59x and the Euro is M381. Title: Re: MK3 ECU's Post by: VwGuy1010 on April 23, 2020, 12:29:58 PM Thanks. Those seem to be it. Can the Nefmoto flasher read and write for this generation? I see some threads for the m383 and 592.

Soldering job. Title: Re: MK3 ECU's Post by: bradyzq on April 27, 2020, 03:02:17 PM Make sure the chip is not OTP (one time programmable). That can end the party pretty quickly.
