Partner 1,9D WJY electrical problem

[baskervil]

Hello friends,
PP 1,9D WJY VF3**************[VIN obfuscated, can be read by forum staff].
After starting the car drove normally. After a while after adding gas, the needle of the tachometer and coolant temperature dropped and the engine started knocking. After a while, the tachometer needle and the engine temperature started working and it drove normally. Then the problem recurred. When the engine was running poorly, after turning the key, the engine light did not light up or glow, the engine starts but runs poorly. A cold engine won't warm up, so it won't start. If I manually close the glow relay, it starts, but does not run well and does not show tachometer or temperature. Changed the glow relay, the pump relay and also tried another ECU. Also found that the alternator is not charging. Alternator sent for repair but all good. The problems started shortly after MOT. Codes P0605, P0215 and P0102 loaded there.

Codes P0605, P0215 and P0102 loaded there.

Can you please add the fault descriptions of the fault codes to save people having to look them up, most people dont know the 100's of 'P' codes from memory.
Also what year is the vehicle?
