It's taken 5yrs but I'm now on my first car with 100k.
As it my daily driver now i will be adding 100 miles a day for my work commute.
I've been very impressed with my 330d and see no reason to sell it but just add another BM later in the year.

Running costs since I've had it from 20k
Normal oil changes by OBC £150-200
Swirl flaps, engine oil leak £400 @ 30k
EBC brake discs & pads £600 @ 85k
New Turbo and oil change £1200 @ 92k

Regular oil changes will now be done every 8k, hopefully this will help the turbo.

Sorry to hear about your crash bro.

Hi, think you may have me confused with someone else.
Both my motors are fine

[makkan00]

Why did your turbo give way?
If you maintain these cars, turbo can easily see 150K.

It's a joke because the photo is upside down.

I was trying to resize the pic
The turbo went because the oil changes were not regular enough and I didn't let the car idle for 30 sec before turning off.

I have the same car 330d and would like to know which fuel you use (regular diesel) or the much more expensive stuff? I have always used the more expensive stuff from shell, Esso or BP, however I am questioning if it's worth 24 pence per litre more? And I am thinking of using just regular diesel. Any thoughts from people with high mileage diesels running on regular diesel!

I did 186,000 mile in my 330d (sold in February 2015). I changed the oil at the 20k or so service intervals as per CBS and used Tesco or Asda basic diesel. The only engine related issue I had was the usual leak from the swirl flaps. Turbo failure is very rare. The 330d is a battleship.

24 pence per litre extra?! Are you sure about that?

mine hit 100k last week 101k this week, may as well keep it now !

I couldn't find any threads on a 330d turbo failure, so was surprised when mine went.
The person who took apart my turbo said it failed because the oil was not changed regularly and you should let the car idle for at least 30 seconds before turning off. This allows the oil to come out of the turbo and not sit there. My turbo was blocked up with lumpy, gooey oil and starved the turbo of oil.

I use shell v power diesel, costs a bit more but I do get another 30miles per tank over normal diesel. The engines a lot quieter and smoother and I'm guessing lots of motorway driving helps.

Idling for 30 seconds before turning off won't do a thing to help turbo life.
The best thing that will help is to drive straight away, but keep it off boost until properly warmed up (Oil temp, not water temp), and drive off boost for the last few miles.
If anything, letting it idle before turning off can help increase temps, not lower them.

i always hear people on here saying to let the car idle for a while. I never know if this is correct some mechanics say so some don't.

Its a pointless thing to do. Driving straight away does the car much more good as it will get up to temp quicker.
Remember, the key to it being good for the car is to not drive it hard from cold.
I cringe every day at work when I see people start their car and 10 seconds later out the gate they are foot to the floor up the road!

Idling before turning off means there is no oil left in the turbo, which sits there until you next turn it back on. Im no expert, but I was told there is a fan or something which stops spinning when the car is off, but on idle is still spinning and allows the oil to leave the turbo. Nothing to do with temps.

Everyone has different views, but this is what I was told from a specialist who has a business repairing and reconditioning turbos and specifically looked at my turbo which had gunked up oil where it should've been clean. This eventually starved the turbo of oil when spinning at high speed and bent the fan which started hitting the sides.

my 330D coming up to 130k not had any issues except changing the thermostats as temps were reading a tad low. Also the turbo actuator arm had a bit of surface rust which was causing boost issues as it was not moving enough - A little scrub with a wire brush and greased it with ceratec and all is running fine again.

Of course it has EVERYTHING to do with temps! What do you think causes the oil to build up inside the feed lines? Heat of course, which gets cooked to the inside of the pipes and turbo, which builds up over time.

When you're sat there idling your engine and oil is leaving the turbo, what else do you think is happening? Thats right, oil is entering the turbo too!

The things that kill turbos are oil starvation and not warming up/cooling them down.
I can assure you that idling it for 30 seconds before turning off won't make an ounce of difference if you are using boost while its cold, or turning it off when very hot i.e.. just after being on boost.
Once red hot, 30 seconds will not be enough to cool it down. Driving for a few miles off boost will though.

Ive been driving and modifying turbo cars for the last 20 years, and never had any problems with them apart from the RS4 I bought that already had an oil seal leaking that I was aware of any way. That was mainly due to short journey in the centre of London where it was never warmed up or cooled down properly, and never driven hard when up to temp to burn off any oil build up.

It is also the reason turbo timers are a waste of time and money. Whats the point of driving off boost for the last few miles and then wanting for the engine to sit there idling for a few minutes, which does nothing more than to help get it even hotter

[mits]

Being my first turbo car, any advice on how to treat a the turbo is welcome.

I come off the M1 everyday 60-70mph for about 40 miles, at what rpm should I keep under to let it cool down as i'd be home in 10mins?
I'm going to add an F10 M5 later in the year, would'nt want the turbo going on that!

ps- I think you passed me once going south on the M1 near Leicester.

[borinous]

if the 330d is anything like the 320d then keeping rpm under 1700 should keep it off boost.

[Digitalize]

Even in 6th you'd be doing no more than 60ish to keep off 'boost'.
