Brake servo removal Megane 2008 1.5dCi

Hi
I am a new Megane owner and really like the car apart from a hiss coming from the servo which disappears when I put my foot on the brake. I have discovered that this is a common fault and bought a replacement servo.

I have cleared plenty of space in front of the servo and in the passenger footwell as can be seen below

The Renault manual refers to removing both of the gearbox ball joints for the K9K engine (1.5dCI). I can't say that I have done this as it wasn't mentioned in the Haynes manual and i am not sure what/where they are. Any comment?

The last stage in the Haynes manual and Renault data sheet refers to removing the two servo mounting bolts (B)
Image

On the Bosch unit these bolts are only attached to the front surface of the servo they do not pass through to the bulk head. I cannot see the point of removing them or am I missing something? I can grip the sides of the servo and rotate it about 5mm but I cannot get it to move in or out when I push or pull it.

I have looked at my replacement unit and it looks to me like the the plate on the rear of the unit can be pushed in to place and then rotated to lock it into place. I suspect the square section has some sort of location lug.

I guess I have missed something out or need a special tool. (The servo is too close to the bulkhead to access the nuts holding the plate to it). Can anybody offer any advice as I am stuck at the moment.

Thanks in advance

Graham

Re: Brake servo removal Megane 2008 1.5dCi UPDATE

Bit of an update
I still haven't got it off but I know what the trouble is. Essentially there is a spring clip located in the square section in the backing plate. The picture below shows this (I have access to a camera on the end of a flexible coupling).





Access is challenging to get at this clip. I can get a hook underneath it and lift it (viewed via my camera) but I need another pair of hands to rotate the servo (anticlockwise).

If any body has any bright ideas of how to lift this spring clip, or is aware of a special tool please post.

Is this a mark 2 or 3..

Re: Brake servo removal Megane 2008 1.5dCi

Final update
I managed to remove the servo by prising the clip upwards and getting a friend to rotate the servo. I did this with the aid of my camera so I could see where to position the screwdriver. I think this would be very difficult to do otherwise. I have put some wire through the clip to make it easier to remove should I ever have to do it again.
