OK, I don't know if this will help or not.
I did a lot of searching on the fault code P2305 and there was one site that had a technician that answered questions (if you joined the site).
The question was about P2305 and the person asking the question said he changed all kinds of parts but it didn't help.
The technician part of the forum said to pay up if you want an answer. THEN, further down someone said, "shouldn't a dealer technician know about the
coil capacitor as that would save a lot of time and money"
To me, that meant that the tech answering the question said something about the "coil capacitor" being the problem or part of the problem.
I can't find any information about the coil capacitor. Here's the link to what I'm talking about if you care to read it......
