On our way home from Looe, we received a call from the lovely Lisa about the second AdBlue problem of the day. Her Peugeot 308 was not only showing AdBlue warnings, but also flashing up a DPF cleaning required message — a double headache no driver wants to see.
Lisa lived in Gorran, which (luckily for her, less so for our travel time!) was on our way back to Hayle, so we were happy to stop by and help.
When we plugged in our Autel professional diagnostic tool, the ECU revealed more than 30 fault codes — far from normal. After a bit of investigation, we discovered the culprit: a broken battery connector that was intermittently cutting power and confusing the system.
Once repaired, we carried out some ECU work, AdBlue adjustments, and a full code reset. By the end, Lisa’s Peugeot was running smoothly again, with no more limp mode or warning lights.
