Turbo Timer's

Do you really need a timer?

I work as a delivery contractor and am onto my second Mercedes diesel [this one twin turbo]. I do between 70-100 stops per day and never ever idle down the turbo - as soon as I arrive, I stop the engine.

Turbos today, with superior cooling and superior oils do not need timers. Having said that it you were going up Mt Ousley towing a 2 tonne boat and wanted to stop at the top to look at the view, I would most certainly idle the turbo for a few minutes.

oops again - put that one on the wrong post - sorry!

Blame it on a long day...

Im with Viz on this, turbo timers are pretty redundant, there is no need to excessively idle down any turbo vehicle.
Yes you should idle them down if you just stopped from a hard haul ie legging it up Ousley, god knows Ive had a few jiggers get warm by the time I reached the top, and you pull over to stop at the top straight away ... But not really neccesary if you just pulled in off a highway to a service station lets say, by the time you have geared down to pull into the service station, parked up and got out, the turbo will have warmed down enough to switch off straight away. Should you feel you need to idle down more, then a 30 second wait would be at most all you would need.

I drive semi's for a living, and at most i'd idle down the truck not more than 1 minute, thats enough time to apply the maxi's, record info on my run sheet and log book, have a drink of water and open the door.

just my .02

The answer to the original question is YES

I had the same one in my 2003 series III 3.0 Patrol'

As mentioned above dont leave it running on it in front of a narky copper.
