Question about Peugeot 308
Hi I have a 308 (2009 reg) which has developed a anti pollution warning and the Engine management light. My mechanic fitted a patent Mass airflow sensor which his diagnostic picked up. This resulted in the car spluttering and generally running poorly. The old part was refitted and the car ran as before but the fault returned when the car was left to go cold. My mechanic will try another MAF sensor in case the part was faulty- although I am doubtful this will result in any greater success. Any help would be appreciated as this is becoming a pain Thanks

yes there is a know problem with the fuel system. fuel pump breaks down, empty your fuel filter into a bowl and check for metalic, if you have this in the filter your pump is F..... along with all the other common rail stuff. expensive job... error codes though, i find that hard to believe, fuel pressure faults will occur, i think you garage does not know what to do. or does not want to tell you the cost of the job and he will be in doubt himself of wether he is right..... was you engine coil light flashing at any point.!!!

Hi i think the problem is one of the coils ( very common on renaults ).
The shaking is the engine missfiring.
Because of the missfiring the emissions are not correct which brings on the engine light.
If you are able to get a diagnosis ( code reader ) done on the car it will tell you which coil is gone
I hope i have been of some help to you

There seem to be 4 sensors along the way in the air intake and emissions system.
My Check Engine light indicated a bad sensor 1, bank 2 code (I think).
I had my mechanic replace the sensor that was indicated as faulty... cost = $191.
Then the Check Engine light came on again (with a different code), and I had to leave the van with him all day.
Cost to replace and install that sensor = $115.
My advice: if the Check Engine light stays on *AND* your vehicle is riding rough, get it fixed.
Otherwise, put a piece of tape over that Check Engine light and save a couple hundred dollars!
Hope this helps, I do trust my mechanic fully.

Testimonial: "Thanks for taking the time to post your advice re my MPV problem. Although not a definitive solution, it's certainly good advice."
My book shows that P0245 is the super/turbo charger solenoid "A" voltage is low.

Testimonial: "cheers for that x18wheeler60 thought it was low pressure not voltage,dont suppose you no which selonoid might be causing this nightmare."
the rear exhaust box has filter in it and the sensor is showing it as blocked ,which i think it could be as their is a problem with this model and it has been modified ,i would be inclined to just fit a rear box with no fancy filter and try to do something with the sensor as it will continue to throw up the light which means it will not pass its inspection ,now the dealer might not be inclined to change this box as its expensive i think about 700+euros the last time i had this problem i fitted a normal box and shoved a shunt resistor across the sensor terminals ,but i dont know what the resistor value was as i took a load of old resistors out of an old tv and i tried then one at a time till teh light stayed out ,i know it had a gold band on it but thats about all
