Turbo Cool Down Idle after Trip?

[MikeR]

OK - I have never done any of the abovew ideas to cool turbo down....and 15 years of driving a Turbo Diesel I have never had and issue, so Im sorry guys Im not a believer in these theories.

I drive and turn off immediately when I stop.

I don't bother to let my cars idle. I do cruise just before I get to my destination.

Anyone read the manual ?

Whatever works for you. I prefer to err on the side of caution. It works for me. Its part of my daily routine. :thumbs:

Best advice?
Buy an N/A car :fencelook:

Ok jokes aside, just do what the guys have recommended here.
I used to follow those steps with turbo cars, and never had a day's issue.

Sorry to hijack thread, but do manufactures recommend this?

I must say I've always driven N/A and turbo cars the same. Always warm the engine up on cold start but I just switch off after stopping and I've never had problems with the turbo cars.

While it may work for some to just switch of at the end of your trip however it won't hurt being preventative in your habits especially if it's coming out of your pocket when it breaks...

Have to agree with MikeR here, I have had turbocharged cars for almost 18 years, and have never lost a turbo and my rules are simple, if the cars turbo is water cooled then the whole idle or drive off boost theory doesn't apply, however with my 200tS which is oil cooled, I follow this regiment religiously. The reason is that when the engine is running the bulk of the oil is pumped to the head/tappets etc whilst on idle is sufficiently circulated through the turbo allowing it to cool. The KKK turbo on my TS is not water cooled like the newer BMW's (oil and water cooled) that I have had.

Idling a car unnecessarily leads to carbon buildup, but each to their own.

This is why I say you don't necessarily have to idle the vehicle for 2 to 5 minutes after being at a complete stop. The times it takes for you to wait for the gate to open, pull into the driveway, close gate, unbuckle your seat-belt, gather your phone and wallet, etc, is sufficient time. We're not saying "you will break your turbo by failing to let it cool down by idling long enough".

It's preventative maintenance and simply exercising caution/care for the vehicle. That's it.

And yes, manufacturers actually do recommend it.

I start my car and rev to 7000 for about 5min. Love it when the rev needle bounces at redline..........................
But jokes aside, I just let the car warm up properly before pushing it hard and let it cool down for a minute or 2 after pushing it. NA or turbo, heating or cooling metal too quickly can speed up wear.
I would very interested to see how the percentage of turbo's failing with the start/stop system? I reckon there is an increase in failure rates...........

Yeah I always let my car Idle for a couple of minutes when I start it and will cruise before I come to a stop then just wait about a minute before switching off, done this one my 135 as well as my GTi when I had that still. My mom has a x3 3.0d and she just starts and goes and puts off immediately and can feel that turbo is not perfect.
