My usual garage quoted for new battery and alternator but we’re not convincing that this would cure problem.
Took it for second opinion who gave diagnosed fault code ‘P1a9c energy accumulator , energy accumulator state of health fault’.
They have quoted for new battery, capacitor/accumulator and a new converter (whatever that might be?). I have found references to this stop/start capacitor problem on the Citroen forum which indicated that it was more likely to be a wiring problem rather than the capacitor itself.
So. . Advice please.
I have already replaced the battery (bad decision as old battery has held a full charge for 2 weeks now). Replacing capacitor will disturb the wiring connections is likely to solve both wiring and faulty capacitor. Do I need to replace the convertor at a further £900?

Hi. My other half’s Peugeot 208 Firenza has problems with the stop start capacitor which I will get replaced.
I have been quoted for replacing the capacitor (reasonable expense) and for the recommended replacement of the ‘convertor’ (lots of money).
My searches on the web seem to suggest that, due to its location, it is more likely to be bad wiring connections rather than the capacitor itself.
My thoughts are that bad connections are likely to be sorted during the replacement of the capacitor and, not knowing what a ‘convertor’ is or what purpose it serves, is its replacement necessary?
I did post this on the Peugeot forum but have had no response.
So - the convertor. What is it? What does it do? And is it recommended to replace it when replacing the capacitor.
Thanks for reading.
