Agreed, changing oil more often is better for the engine!

apart from letting the car idle for seconds or minutes after a drive, when you own a turbo car you should adopt a different driving style, what i do after a hard drive is drive the car a bit slowely for the last few kms, this eliminates idle time alot.

Ur car can goo fast :rollsmile:

This is something quite interesting for me.

Not all new turbo cars are owned by enthusiasts or people with any knowledge of how a car works.

I have mates with turbo cars (new) that hammer them within an inch of their lives and then turn them straight off.

Surely manufacturers have forseen this and put measures into place? Or am I way off?

I have a 200tS that i religiously drive chilled a few kays from home and then idle for 2 mins on a stop watch. To me it feels like you are being kind to the motor.

Hi Guys

Sorry a bit off the subject but I have been searching around my 320d and does it have an electronic oil level checker or not

tell you the truth I have not opened the bonet yet so I have not checked for a Dipstick

A dipstick is quite foregn to me now since for the last 5 years I have been driving a 323i which has an electronic one.

I also looked at the instrument cluster on startup and there is no oil light that I can see

Whats going on does BMW want me to get stuck somewhere wihout oil :)

No dipstick and no oil guage

I can't believe it

its crazy does it not use oil at all?

How do you check the car before you go on a long trip?

most turbos last 100kkm+ with a bit of a beating. If you care for it correctly, it will last much longer, liker mine.

I was reading the owners manual for my 320d last night

I was a bit surprised when I read that there is a run in period for the car of 2000 km's they they say I must not rev it past 3500 rpm oops I have done that a couple of times but will stop now

I read that whole section it has something for when you start the car they say its better to drive off straight away and not idle it to warm up so I assume if you drive it away and take it easy till it warms up this is ok

But no where in that manual does it say you need to cool it down before you switch off

I am not saying its a bad thing to drive it easily for the last km or so before you park it but to idle it for minutes I don't see it as needed and them not mentioning this in the manual tells me they must have some protection for that

I mean they have to cater for the people that don't know squat about engines if they just drive the crap out of the car and don't worry about anything and there is no built in protection that turbo will blow prematurely thats almost garenteed and with a lot less km's than 100k. I think this is what was messing up BMW when they first came out with the 320d people would not look out for the turbos and they would replace them every service.

I don't know guys just my thoughts

I also said it before, it is always better do drive off straight away. BMW engines are not made in america and take less than a second to get the oil up to pressure. My 1979 Porsche takes 1-2seconds to full pressure after startup.

There are many downsides to idling a car after startup - a big one is oil contamination. The fuel ratios are very far from ideal when idling with no load, and this will contaminate the oil very quickly.

Truth be told, BMW did design the car so that you do not need to idle it before shut-off, but they were taking into account what they consider to be "normal" driving. Most people with diesels don't drive normally anymore, because boost is addictive. Believe me, it is always better to idle it.

That said, I'm pretty sure they consider the turbo a maintenance item, because it is more like tyres than an engine - it does wear out.

you shouldn't start the car and let it sit, as the oil will circulate far more efficiently if you drive the car, just drive more sedately for the first minute or 2 and then do whatever you want, and then let it cool down once you get to destination.

certain turbo's have sleeved bearings so when you turn of the car, an electronic pump keeps on pumping oil (or water depending on the turbo) through the sleeve and cools the bearing to stop oil buildup that way... but i dont know of any cars the come standard with that setup.

you also get turbo timers that keep the car running after you turn it off and if somebody were to try steal the car it cuts off (works off a switch on the handbrake or revs) but that is not a legal aftermarket tech in SA from what i am aware...

N54 has a electronic waterpump - and watercooled turbos, so it does run afterwards. That said, it is still a good idea to let it spin a bit while cooling.

P1000 is this the turbo they use on the 320d's?

I have a 2011 320d with 3,500km on now.The dealer told me I must take it slow for the first 2,000km and then I can gun it.I let my car idle about 5 min before driveing and 5 min and 5 min afterwards after I also drove like a Granny the last few minutes.I had a 2007 320d before this and also never checked the oil.Never had any problems with the car for the 80,000km I had it.

Enjoy your 320d's guys and look well after the turbo's.

Nope, that is the engine they use in the 135i/335i etc.

That is probably the best way to contaminate your oil! Not to mention annoy your neighbors. Just drive it gently until it is up to temp, idling a cold car will do more harm than good.

I have found that letting the car idle for a couple of minutes on cold mornings sometimes let the EGR valve stuck and left me with a trail of white smoke which only went away after I stopped and restarted twice or so.

Also idling a cold engine means it takes longer in most cases to warm-up, and most engine wear occurs when the engine is cold. So not really a good plan. Unnecessary engine wear, oil contamination, and fuel wasted (maybe to a much smaller degree with a diesel, but definitely so with a petrol).

Start the engine and give it a few seconds to "settle" (fluids move around and build up pressure where needed), then drive off gently. And this counts for the entire drive-train - gentle on the clutch and gearbox! You can't prevent wear and tear, but you can minimise it...
