Hi Alex,

Hopefully you've got your problem resolved by now, but in case it's not.....

I did a lot of thinking about your problem, as it you originally described it, when I was stripping down my throttle body assembly prior to removing my supercharger yesterday. Is it possible that the small bore hose (I don't know if it is pressurised or vacuum) from the supercharger distribution duct (for want of a better description) {pic 1} became dislodged from the 90 degree connection on the electrical sensor? (I don't know what it is) {pics 2 & 3} when you ran out of fuel? This is quite probable if you experienced any form of misfire/back fire because it is a very loose fit on mine.
I don't know what the switch/sensor is for, but it is located roughly behind the glove-box, where you said the noise originated, and if disconnected would possibly blow supercharged, but un-metered, air to atmosphere. This could well explain the escaping air noise sounding like an open relief valve and might explain the extra/over fueling because the pressure is less now after the sensors!??!







Hopefully my pictures will help you understand my poor explanation, if not please be gentle when you tear it to pieces.

Anything is possible and worth looking at. My car still remains unfixed st present.

My injectors have tested ok so blows that theory out the window at least

Thanks for he info I will let LR know and see if they can look at it for me

Back from holiday last night and drove the car this morning for the first time, no air noise, no lack of power and fuel consumption back to where it should be.

Fingers crossed everything all ok.

Will drive it for a week or two and make sure all is well and then look at changing the oil in the supercharger as has been recommended.

Thanks for all the help and suggestions  Alex
