SOURCE: Peogeot 307 suspected faulty reversing light switch.

The reverse light switch is located on the transmission housing which is behind/under the air filter housing/battery on the 2.0 litre D turbo model. To replace it you will need to remove the top of the air filter housing and the filter (2 screws plus release the air intake pipe connected to it by a large jubillee clip, also unclip a couple of cables). To remove the switch disconnect the cable clipped to it. You will need a deep 22mm socket and a universal/flexible coupling to unscrew the switch (as access is poor unless you remove the battery compartment/air filter housing).

SOURCE: depollution system faulty peugeot 308

Well its a 2009 and as such its all electronic control and it can only be diagnosed using the dealer software via the internet this is to stop people like myself from doing anything to it ,from the sound of it i would suspect the throttle position sensor under the dash on the end of the throttle pedal as this fault i have had before on more than one occasion even more so with my favourite )not( make of vehicle a renault but in all honesty you are in the hands of the dealers here as they are the only ones with access to the software via the internet with the factory ,Sorry i cannot give you a nice fixya easy type fix

I have Peugeot 207 gt cc, the depollution system fault sign keeps bleeping up and engine management light has come up! Cam sensors are fine, plugs are fine! Car is 58plate petrol!


You need to have a OBD2 fault code test performed to determine what codes are present in memory, based on that test you do the prescribed diagnostics testing.

Peugeot 2007 depollution system faulty warning light


Sadly a common fault with 207s is random fault warnings coming up on the display.

If it's a real fault, then you should notice a fall off of performance and this indicates a trip to your garage to get it fixed.

If the fault comes and goes, or there is no loss of performance, do what most 207 drivers do and ignore it !
