What faults do you have?
as lots of people buy cheap code readers hoping to be able to read abs, airbag etc faults not realising they will only read engine ecu not any others.

Hello,

I have the usual vague anti pollution fault that seems to be a 206 specialty.

I took it to a garage and I am pretty sure they didn't even plug it in.

It is intermittantly going into limp home mode (usually going up hill or driving on fast roads), no alteration in mpg, runs a bit rough in limp home.

I was told the codes were: p0401, p0110, p0101. I have checked the air intake and changed the air filter just in case, and have looked at the MAF sensor and given it a clean with contact cleaner. The only thing is as I do not have a reader to clear the fault codes I am not sure whether the codes have been fixed but that the car hasn't been told. I have tried disconnecting the battery for an hour, but that doesn't seem to work.

I have also tried dpf regenerator as someone suggested it was that. It did seem to make it play up a little less, but it still has the fault code showing and the engine light on all the time.

 

Clearing the faults will not help in itself as said above you are better with planet as this gets you live data as well as codes so you can see what is actually wrong more acurately

 

Thanks for your help. I may have to invest in a reader then, I was hoping I could get a OBD reader, but life is never simple!

If I managed to actually correct the fault i.e. the MAP sensor, but couldn't remove the code fault, would it still go into limp home mode because I hadn't erased the fault code? I have to say these new pugs are a pain, I want the old 306 back, I never ever had these issues in 7 years of ownership! I made the mistake of getting two of the devils, one with a faulty door catch, and then this one. I won't be doing that again.

 

For future refrence it is not recomended to use contact cleaner on MAF sensors as most leave behind an oily film. MAF sensors should only be cleaned with Brake or Carb Cleaner. (Brake cleaner prefered as not so aggressive as Carb cleaner)

 

Oh right, thanks, I was told by the garage that it would be ok, typical!! I wouldn't mind, I have got the brake cleaner already, its not been my week, oh well, at least I have learnt something new.

Thanks for all you help, off to kick my car!

 

My experience has shown electrical contact cleaner to work OK. The wires in the MAF get hot anyway and burn off any residue (or are supposed to if its working OK).

Its things like WD40 which aren't recommended.

 

On another note is there a way to check the MAF is working ok?
