I've just had my blown turbo replaced under warranty at 50K miles. Due to the turbo failure, it also needed a whole new exhaust and sensors. As this would have cost somewhere in the order of ?4,000 inc. labour, I am now a little worried about the likelihood of failure when my 3 year warranty ends next year :'(
The dealer said it was rare in 5 series, but more common in 3's.
Is it common in E60 diesels ?
Thanks.

I've heard it's pretty common in the 3-serie (E46 - 320d), and I know we have a few on this board with 530d (E60) with blown turbos
I don't think it's common on the E60, and I really hope it isn't..

It looks like it's a common problem if you read on German forums especaly 530d and 535d. A lot of drivers dont let the engine work 30-40 sec before shut off and this could couse big problems due turbo failure

I've gone through one turbo already I've got a 530d sport auto 54 plate currently on 29,000 miles, turbo replaced at 26,000 miles.
Mine didn't go with a bang, just stopped working one day, no smoke just a loss of power, took it out later that day and turbo was working again although not quite right, took it into the dealer and they decided on a replacement turbo.
Feel a bit concerned about running this car out of warranty now, does anyone know what you'd be looking at for a replacement turbo from an independant BMW speciallist?

It is recommended with all turbo models that after a fast run your allow the turbo to cool for a minute or so before shutting down the engine.
Otherwise the residual heat in the turbo carbonises the oil, then when you start up you get excessive wear.
Running it at idle for a minute or so allows the oil to dissipate the heat and prevent this problem.

And how safe it is this procedure, i mean if you do that what are the chances to still have a turbo failure?
I always let the engine cool down at least 2 minutes and at least 5 after it was driven really hard. Is it recomended to do it ALL the time? I mean there are times that i drive the car in city and i don't even pass 1500rpms. Is it ok in this case to shut it down instantly?

The advice I have been given is after fast runs.
Easiest example is when pulling into motorway services, 2 hours at speed followed by instant shutdown is not the best way to treat a turbo.
It will not guarantee turbo health, nor is this the only reason for turbo failure, but giving it a minute or two to cool dwon makes sense to me.
Just driving around at town speeds will not cause the turbo to develop the heat leveles that cause the problem, likewise a motorway run which is followed by 15 minutes low speed driving allows plenty of time for the turbo to cool.

I used to drive a turbo and had a turbo timer installed. So even though I turn the ignition off, take out the key, and lock the door, the engine is still running and cooling down. You should cool your car at least 30 seconds to a minute after EVERY drive if you have driven for around 30 minutes. The longer and harder you drive, the longer the cooling time. but if you're too lazy, I would say just get a turbo timer.
