- Warming up motor before driving, how long should you let the motor idle for ideally (and practically) before taking off?
About as long as it takes to put your belt on, check your mirrors and select gear...
Just drive smoothly until normal operating temp is reached.

- Same for cooling down after driving, how long do you let it sit in park before turning it off? Obviously it's better for the turbo if it cools down, does anyone recommend turbo timers for the D3's – do they need them?
Do not fit a turbo timer (and they mess with the vehicle security anyway so are a pita)
Drive gentler towards end of journey, then idle down whilst lowering EAS to access height.
On hot days or heavy loads / towing idle a bit longer..
15 seconds after gentle run down is ok in 99.9% of cases.
Our work Turbo diesels are just turned off!

- Anyone recommend those temperature gauges that give readings on the motor temp? Not a bad idea...

- Diesel quality, choose high turnover outlets, have heard bad reports from w**lies fuel outlets? Reputable outlets, name brands... Avoid Bio!

- Any diesel additives? No

- Every once in a while give the motor a solid rev to clean out the pistons? No... But a good hard long run will remove the soot from urban running.

- etc etc.

Thanks in advance!

Do regular oil changes and ALL filter changes.

All motors require clean air, clean oil, clean fuel and correct cooling. Look after those and you will go a long way to increasing your engine life.

All the points Tombie makes are spot on for a modern turbo diesel.

Hi Gords,
I saw the following report the other day - not much of an outlay!

Hi Gords,
Agree with everything Tombie said........good advice.
The old way used to be to warm the engine whilst going back inside to do the 3 S's (shower, ****, and shave), however, this will not circulate the oil around the engine as quick as a gentle drive, almost immediately.
Diesel motors like to work, but not necessarily rev. You are better off towing with something heavy up hills ocassionaly rather than rev the crapper out of it.
CHANGE OIL & FILTERS REGULARLARY............most important.
Cooling down - A gentle cruise at 100Kph on the freeway should be followed by a slow drive to home once in the 60Kph zone. Once home, I always unbuckle, grab everything out of the vehicle that I want to take inside (sometimes even check the mailbox), then switch the engine off.
BTW: The above advice is from a family member who is a diesel engineer & mechanic.

Cheers and happy motoring, Craig

Thanks all for the informative replies! Just goes to show how clever these motors actually are!

Tombie; One question: you mentioned "Drive gentler towards end of journey, then idle down whilst lowering EAS to access height." I presume by your reply that you recommend lowering your height to access when parked, even when that height mode is not required?

Jonsey63; The one in the link you gave looks good (and cheap!), I found one on ebay and it was $110 or soemthing. It would make a good cheap overheating alarm. I heard a story where someone blew the radiator on a D3, cooked the engine and the replacement cost of the motor installed was circa $20k! $25 seems a small price to pay to save $20,000!

Disco4SE; Sounds like a good habit to get into!

Cheers, Gords

I am serouslt considering when mine needs the timing belt changed getting sump taken off and the big end bolts checked. There have ben some big end failurs and it is thought some of the bolts had loosened.

Yep, CaverD3 , seen one of those loose big end arrangements close up allready ,with the cracked cap style bigend ,apart from a lack of QA.QC its hard to see how it happens.
Given that ,Id still have the EGR system completely Blocked/removed if you have seen what I have seen in every TDV6 and TDV8.
