Technical Seicento ECU issues

[Reffter]

Hello,

I have a Seicento 1.1 that has been giving me the dreadful P0351 trouble code. After changing coil A with B, the issue remains, and it's sporadic. These past couple days, this issue has been getting worse, so I'm on the lookout for a ECU and new coils. The part number that is installed on mine is 46817821, HW004. I can find a virginised ECU on eBay for around 140€ shipped. Would I be able to get another part number/hardware revision for my car?

Regards,
Reffter

Problem solved - new used ECU from eBay and new Marelli coils, made the ECU virgin so it was plug and play. Runs great!
