Thank you for your reply
You're right! P0351 does not appear in the manual. And, this is what surprised me as well since i checked it again and again myself.
The speculation here is that since coil pack 1 is fine, maybe its connector or harness or some other electrical cable might be faulty resulting in a comm. bus error and ignition pack 1 not responding properly.
This is pure speculation. I might be totally off!!
