Possible air leak

[merlin_boon]

I have Just bought a 300te, with the engine on and running, there is a hissing noise, which sounds like an air leak.
Also the central locking is slow to work, is this related?.

Can anybody help please?

its possible

the main pipe from the vacum pump has loose fittings hence leaking air, think somone will back me up on this. not sure were the c/locking pump is on my old 123 it was in the boot?

Not sure about the TE but on the 124 saloon its under the back seat.
I have a similar problem with the central locking, I put it down to the car being idle for a year. Hopefully it will improve with use?

Good Luck
