Active Exhaust Stuck Closed

[Arne]

Copper slip.
My exhaust valves were squeaking and I wasn't about to shell out £1400 for a new back box so I got the technician to apply copper slip at my last service.
They were a bit sniffy about it to start with, now they want me to report back as it might be a fix they use on other squeaky f types.

I had the same done on mine during the last service - just as a "preventive maintenance". Not experienced any problems or noises before or after.

so jag now have sorted the issue, after going in for another unrelated fault (see other thread!!) and it turns out they were indeed stuck open (quite mode) so apparently they freed them up, greased them and all sorted. For now...

Sadly not.
I am going to have a go myself when I take the car to my mates garage and put it on his lift.
