It all depends on what you mean by updates.

If you want performance / fuel economy improvements then you are looking at getting the ECU remapped. I'm guessing you have an automatic gearbox and would imagine that if any updates are available then it would need to go to a Peugeot dealer to get the updated software.

As for oil, any good quality oil of the correct grade should be fine. I know it's recommended to use fully synthetic in a diesel engine but don't know what the recommendation is for a petrol. The correct grade and type of oil as listed in the owner manual from a known quality manufacturer should suffice.

As for your heater. Are you saying you get warm air blowing into the car even with AC switched on. If so then it may need a re-gas on the aircon system. If the gas has leked out then the compressor clutch will not engage so no aircon pump meaning no cold air coming into the cabin.

Your questions aren't very clear and you don't explain fully what it is you are asking. Try to give as much detail in you're questions. You know what you mean but that doesn't mean the rest of us do so the best we can do is either not reply so we don't give incorrect advice or we try and guess what it is you mean and give the best reply based on what we think you are asking.

About the heat if i turn the AC on its work and won't effect. I checked ac and work fine


My problem is like air come from engin and leak to AC canal.. I think there is kinda hole or something that's make worm air blow into car like I turn the heat on but its off

I hope you understand what I mean

Thank you for reply

Do you have manual A/C or the auto digital A/C ?

I would suspect it maybe the heater flap controls that are faulty. If the flaps can't close off the warm air then it will always blow warm regardless of the A/C being on or off.

There is quite a substantial thread on this forum covering heater repair.
