Can't say that I've done many '06 Beemers; but the Mazda 6 has a big issue with prematurely-failing high-pressure pumps.
Never seen any difference in the longevity of turbos whether simmered or not. Oil quality/changing appears to be the biggest factor.

That contradicts everything I have come across in 21 years of turbo motoring (I had an '83 Metro Turbo in 85).
About 15 years ago I was following a 524td down a German autobahn when the turbo blew, masses of smoke and it seemed like bits of metal were coming out from under the car, I guessed turbo at the time though could have been engine failure.
Re the BMW and Mazda, if going in the same direction they could have both filled at the same station from a dodgy batch, water or petrol in the diesel .....
.... or it could be an outing by the local branch of the "lets run our cars on used chip fat" brigade.

Some people may remember my MiL's Merc E320CDi which stopped driving properly.
It got fixed recently, but a hose came off the intercooler pipe so not enough air got into the engine. The car was throwing loads of black smoke, nut runs sweetly now the hose has been re-attached.

What was the final fault diagnosis when it was fixed?

Good question!
The mechanic has not told my Mother-inLaw, what he has done, becuase she has not seen him yet. She brought the car to Manchester last week, from London and it was during the drive that the pipe came off.
I took the car to my mechanic, who looked at it and it seemed to have had a new turbo fitted and I think a new ECU. But I not convinced the ECU was the problem. Given the lack of driving the car has had, it could easily have been the turbo.
Anyway it now acclerates like a rocket and does 35mpg around town to boot. I've just sold it to my secretary's boyfriend for £9,250.

Some years ago when Diesel Car magazine was in its infancy there was a two page article on turbos, mainly interviewing the technical expert from the leading UK firm who recondition them.
He was asked the question about whether turbo diesels should be allowed to simmer for a period to allow the oil to cool.
He didn?t seem too impressed or emphatic that they should, and when pressed he said well it might be necessary if you were towing a caravan up long steep hills and stopped at the top. But generally there was really no need.
His emphasis was more on having a good quality oil changed regularly and he expected that with this regime most turbos would last the life of the car.
Having said that I do it myself but then again I don?t walk under ladders and am always very wary on Friday the 13th.

I sold a turbo over the counter some weeks ago, I told the customer to read & digest the information booklet supplied but he didn't seem interested. He didn't even want to buy a new oil filter & oil!!

Diesels do blow turbos. A friend's Land Rover Discovery did at 8000 miles. He is a press-on driver who doesn't simmer, but he had lent the car to someone who returned it with 2000 more miles on it and a muddy towrope in the back, so perhaps it had been abused in some other way.
I would say, better safe than sorry.
The new C4 turbodiesel I drove the other day has the turbo right at the front in the airstream, covered with a heatshield plate with a very big don't touch logo - a formalised image of a hand with a diagonal line through it. This shield, coloured silver, was putting out massive amounts of heat just from pootling about in traffic.

Diesel turbos do not run to the extreme temperatures petrol turbos do.
