EP13 | P0352 Misfire...Not the ECU?! (Peugeot 307 CC Fix)

EP13 of A Very British Fleet… and Patricia is back causing chaos 🤦‍♂️ This time it’s a P0352 misfire fault on a Peugeot 307 CC — and everything pointed towards the ECU. Multiple misfire codes, rough running, and an engine that just wouldn’t behave… it looked like a big, expensive problem. Bizarrely it evned out at 2000rpm But it wasn’t the ECU. In this episode, I work through the diagnosis step-by-step and uncover what was really going on: • Fault codes: P1336, P1338, P1339, P1340, P0352 • Oil leaking into spark plug wells • Failed ignition coils (“Kentucky fried” spec 🍗) • Split crankcase breather hose making things worse • And a hidden wiring fault at the back of the engine I’ll be honest… I got part of this wrong first time 😅 But that’s what this channel is about, real-world diagnostics, learning as we go, and fixing cars properly without throwing money at them. Massive thanks to a legendary Polish mechanic who helped point me in the right direction: “dziękuję legendarny polski mechaniku” 🇵🇱 ⸻ 💷 The result?
