Skoda Octavia 1.8 turbo PETROL Auto management light on was intermittent but now permanent drives fine except a few shudders going up steep hill but was low on fuel almost to start of empty red line

try putting your foot on the brake pedal before you put the key in then try to start it --if no lights its the brake light switch thats faulty

at turbo line .

first check the rear brake light if its working when apply brake if not replace rear brake light s.w .

and find this out. easy.

well cant see the light on for that but if mount is broken needs fixed right away

Sounds like faulty coil. Check this on a diagnostic machine at a garage and you will get the answer.

Auto warning light comes on but goes off when car stopped and restarted. Temp also goes higher

If you are "lugging" the engine, you will get increased exhaust temperature (EGT), this will trigger your "turbo" light(not a good thing), ideally you should have an aftermarket "pyrometer" fitted to your car, this will show you the optimum revs etc you should be using in any given circumstance.Or revise your driving technique, ie change down gears earlier.
The turbo should be idled down after long trips or heavy towing, this allows the oil temps to stabilise and turbine speeds to stabilise, thus idle for 2-5 minutes.
