O/s rear lights not working on my Peugeot 308

Fuses F15 and F16 are okay?

This says it might be the switch. I can't find relays, so the switch is carrying the power (amps) instead of switching it through a relay.

Question edited from '3008' to 308, and improved the written English a bit. :>D

You can purchase the code, which is based on the serial number of the unit which you will find on a sticker on the rear or the side of the unit. Many of the sites say they are free, but expect to pay $18USD or 12 quid to get the code.

What voltage are you getting to the bulb sockets with engine running ?

Bet no electricity reaching the cluster. Get a hold of the schematic and check out all of the components in line between the cluster and battery.and switch. And do not overlook the ground connection.

Check the rear lamba sensor with a multimeter ,if heater circuit not working it will give the wrong information to the engine management system causing a weak mixture

There can be all sorts of other DIY's from draining, flushing and refilling system, thermostat replacing and buying a new car.
Mine from City Peugeot was going to be a £2000 fix and they didn't even know what was wrong.It was just a hail Mary.
Other things that beat them was the rear light cluster not working - £400 fix, was just a loose fuse in the glove box.
The 26mpg when it should be 43, they just say is in the ok bracket, even though I reported it within 2 months of buying and it was sold as 43mpg.
Best advice - do not buy another Peugeot. I now cycle everywhere unless it is raining. I stay local and cant afford another car. Thats all fair I suppose.
