The turbo cooldown is a myth on modern turbo diesels unless you have brutally nailed it and switch it off immediately. Even then it's unlikely to cause trouble. It stems back to the older times of petrol turbo's that get much much hotter than a diesel turbo and in the olden times mineral engine oil was used, that used to build carbon deposits in the turbo when switched off hot. If these (or parts of) came loose, it would damage the inner mechanics and wreck it.
Modern, fully synthetic oils, very large intercoolers and generally lower temperatures in the diesel turbos make it not necessary anymore. If it gives peace of mind it definitely doesn't do any harm, especially not after a really hot run. Usually the last one or two slow approach minutes of a journey are good enough.
On the issue of blown turbos, there was a lot of them with older than March 03 E46's and also E39's. The units afterwards were much more reliable.
I haven't heard of that many on E60/61's yet. It always looks worrying, as it is normal for people to come back on here or other forums and report about a failed than going on any forum to report you have no failures at all

My turbo was replaced. It was noisy (whistle), so the dealer replaced it under warranty. Seemed to be working perfectly OK otherwise. Maybe it was about to blow, I don't know.

My turbo was completely blown at exactly 100.000
Altough the car is from 6-2004 I only had to pay the labour (350?)
No exchange from other parts altough there was a lot of oil burned in the motor.

Hi guys,
just a few points. the reason why we see very few blown turbos on this board is simply because 98% of the users here drive a petrol engine. If you really read the german forums, you will see atleast one blown turbo per week. the 3.0d has always been a fragile engine, ever since the introduction with 184 bhp. there is no way of stopping this to happen - people who have driven their cars gently have had blown turbos, and those who have slammed their cars have yet to have any problems. fact is, modern engines need less care (ie. waiting after blasting it on the highway) - it generally is disappointing that we are sitting on a ticking bomb
see you rumman
