Peugeot 4008 immobilizer issue
Summary of the thread
A 2016 Peugeot 4008 is experiencing an immobilizer issue where the engine won't start or starts briefly before dying, accompanied by an error code. The problem is likely due to the car's ECU not recognizing the key's transponder signal. The suggested solution is to have the key reprogrammed at a workshop, which resolved a similar issue for another owner.

Battery's fine. I've tried both keys, same result. You said similar issue – what was it exactly?

Right, yeah, mine was also intermittent starting then cutting out. Turned out to be the key programming. The transponder signal wasn't being read correctly by the car. I'd suggest taking it to a workshop to get the key reprogrammed. Cost me about 45€ to fix. Could save you a lot of headaches trying to diagnose it yourself.

Thanks for the tip. Got it sorted at a local garage, new key programming. Exactly as you said. Cheers!

Hey, I had a similar issue with my 4008. Symptoms sound the same - engine cuts out. Immobilizer is an anti-theft system that uses a transponder in your key to communicate with the car's ECU. If the ECU doesn't recognize the key, it won't allow the engine to run. Did anything happen before this started? Like, battery died or anything?
