Peugeot 5008 Starting Issue

Check the battery cable connections first. A bad connection can cause starting issues and trigger the engine light. Is the engine light on?

Where exactly should I be looking on the battery cable connections? Anything specific?

Check for corrosion, loose terminals, or damaged cables. If everything looks fine, it might be something more complex like ECU failure. It's best to take it to a workshop.

Thanks. You were right, the battery cable connections were the problem. Repair cost was 155€.
