Afternoon all!

Hopefully a bit of a sensecheck from those more familiar with the aircon workings on the speed6.

The aircon in my Tuscan has always been a bit rubbish (partly due to the only outlet being in the lower pod behind the steering wheel, and partly as it's never really ice cold) so i've not really used it that much and just taken the roof off when it's warm. Recently driving along the motorway, i heard a loud screeching/belt squeal and the engine suddenly died. I coasted to a halt thinking the worst. I turned everything off and on, disengaged the aircon, and the car started and drives fine.

Engaging the aircon and the car idles much lower and laboured, but no belt squeal.

So... time to recondition the compressor? If so, any places to recommend doing it? I would appreciate any input if anyone has had similar symptoms or had a failure? I found it hard to believe that the compressor managed to stall the engine whilst travelling in 5th gear at 70mph. I would have thought it would have shredded the belt instead?

If gas is low, lubrication is also low, because the oil uses the gas for flowing through the system.

So it is a maintenance failure!
Ist not a TVR fault, it is a fault of the TVR owner!

The Aircon was re-gassed 1yr ago, and pressure tested so i'm wondering if i have a leak then!

When i've used it previously the idle has/does always drop be a few hundred rpm as i know it does place an extra load on the system.
I don't think this will be a DiY fix, just interested to know whether it could have such an effect as to stall the engine!
