You can certainly change the battery yourself if you're comfortable with it. Just make sure you have the correct replacement battery and follow the manufacturer's instructions carefully. However, the rough engine running might be a separate issue. It could be due to a variety of reasons like spark plugs, fuel injectors, or even the air filter. I would recommend getting a diagnostic scan with your Carly adapter to pinpoint the issue. After replacing the battery and running the diagnostic, let us know how your car is performing. Do you have any other questions?

Minulla on ongelmia Citroen C4 -mallissani, kun akku on tyhjä moottoria käynnistettäessä ja moottorin käynti on kova. Minulla on Carly-adapteri ja mietin, voinko vaihtaa akun itse vai pitääkö auto viedä korjaamolle. Onko kenelläkään kokemusta tästä tai voiko joku antaa minulle neuvoja?

Voiko Citroen C4:n akun vaihtaa Carly-sovittimella?
