I have this problem on my Renault Megane 1999 Alize. The knocking noise happens when I switch from internal to external circulation. When it happens I get about 25 loud knocks, that drives me and my family mad (suicidal they say). My car has air conditioning and an inspection of the air motor unit from under the bonnet suggests that it is difficult to fix by yourself. Not only does it have air conditioning piping emerging from the box but the box itself appears to be placed deep down behind the engine and bodywork. I'm not sure that it is possible to get to from inside the car as there appears to be metal bodywork in the way. Does anyone know whether the air conditioning unit fluid has to be drained and replaced?

Megane noisy flappy sound when ignition switched on.

When I turn on the ignition on my Megane 1.6 RXE a noisy flappy type sound happens in the front bulkhead it goes on for about 10 seconds and then everything works fine untill I start the car again. Somthing seems to be loose in the front bulhead as when you close the car door you can hear it flap could anybody point me in the right direction.
Cheers,
Pete

Sounds like the solenoid that operates the recirculating selection flap is acting up and expensive to fully repair - try this - disconnect the cables to the solenoid and then jam or lock the flap in open position so air is drawn from the outside. A bit awkward to do but also a lot cheaper.:)

I took out the removable flap at the top r/h side of the bulkhead and at the r/h side under the plastic I couldn't lift up ther was a large conector with several cables going to it and just th right of that ther was a smaller conecter with 2 small cables going to it I thought that may be the soleniod I couldn't lift the conector of the housing if this is the corect conection I maybe could cut the cable and make safe.
Any advice will be greatly appreaciated.

I looked on a previouse post and was told it was the recirculation flap that was making the noise. Some one else had same problem and they disconected the motor for the recirclution flap and that shut it up but i,m not sure wich one it is. I think all it does is stop exauhst fumes coming into the car when reversing so no big deal to disconect. I just need to silence it without paying £400 to get it done. If all else fails I may do a Basil Fawlty on it.

We are all in a flap

The flap is there to change the direction of the airflow into the heater - when it's open it allows air to be drawn in from outside - when it's closed it recirculates the air from within the car. But what I'd really love to know is what reversing has got to do with it.:confused: If your going to disconnect it the flap is best left in the open position - so in warmer weather (whenever it arrives dear knows) you can have cool fresh air when required.:)

This is the problem I have - saw the red and black wires (hope those are the ones?) but they looked rather large. Does anyone have a pic of the wires to disconnect. Have just recently acquired the car (99 1.r rte Megane hatch) and love it. Quotes for a repair are unbelievable here (South Africa). Would like to have a go at some stage, but not sure whether to get in from the inside(engine compartment) or inside (then how to get under the dash?). I can feel that flap if I wiggle my hand in to the gap.Very frustrating. Be great to see pics of s dismantled unit.
Thanks
