I have just bought a fabia vrs and have been told that i need to leave the car running for 30 seconds each time i use it to allow the oil to drain from the turbo charger....I s this important for every journey or only when i rag the car?!?!? I also understand you can get a piece of equipment fitted to the engine that keeps it running for a set duration of time when i have turned it off. Is this the case? and if so how much is it?

Thanks!!

dont' think it's necessary unless you've been ragging it. the device in question sounds like a turbo timer...

IMO not needed unless you intend to do 3 figure speeds before parking up straight away - a good warm up policy is a better idea on a tdi. If you have been ragging it sillly as it were then give it a slow drive home for a min its a better way to cool down. Its not really an issue, turbo timers arent insurance friendly either

agreed. warm down drive the way forward - someone once put this as "how much do you think a big cast iron turbo will cool down in 30 seconds?" which kind of makes sense....

it's not the turbo cooling down which is the issue tho, it's more to do with the temperature of the oil left inside after the engine has been switched off. if the turbo is hot the oil cystalizes and ends up wiping out the bearings

I asked a mechanic buddy of mine about letting the turbo spool down

He basicly told me

By the time you get off any fast roads and get to your house via the slower 30mph roads your turbo has spooled down enough

Thjis doesnt count for folk living on motorway sliproads:D

Yep the idea is to draw away the hot oil in the turbo. Don't think it's really an issue on a TDI as they don't get as hot as petrol turbos and, unless you pull into a service station on a motorway, you'll have probably done enough driving to your house.

I once blew a turbo on a skyline after pulling into a filling station - nothing to do with the porsche a couple of miles down the road (*honest*)

I sometimes allow our fire engines to idle for 30 secs before i switch it off to allow the turbo to spool down etc so the bearings have oil pressure. Makes them last longer as they are build to last a long time and very expensive. We are taught this when we do our advanced driving course to drive on blues. Mind u we really do rag them all the time.

I assume the turbo in the VRS is somewhat audible as in most other turbo cars - Volvo, Audi...? If you can still hear it spooling down once you've parked, wait until you can't hear it anymore. Never hit the accelerator right before shuting the motor off as that leaves the turbo with hot or little oil as the gear pump only pumps when the motor is on.

The timer your talking about... Is it an inline electric oil pump or ignition off timer? If you rag the car alot and shut it down quickly, it might be an idea to install something like an Accusump or Lubrication Research electric sump as this provides prelubing to the motor before it starts and the possibility to put it on a timer after the motor has shut down.

nah! turbo-timers are basically a gloryfied stopwatch

All very well but lets face it when you're turned out the wagons go from sitting still to getting ragged. The same can be said for feather-weight pumps, generators etc. Mechanical sympathy has no place in the fire service.

The job's fooked so the appliances should just follow suit ;)

The jobs not fooked its just you have to adapt and play the system

I'm not playing until I get my LSI or CPD !

they stopped our LSI this month and err no sign of the of CPD but lots of threats of developlement payif you dont complete maintain the compencys lol
