When driving a turbo, or any Diesel for that matter, it is best to
drive sedately until it is fully warmed up (normal oil temp, not
water temp) that is under 1/2, 2/3 or 3/4 throttle depending on how
many cylinders you have. A 4 cyl MB is in the 2/3 to 3/4 range. and
SDL is in the 1/2 throttle range. When coming down after a highway
run, you should allow the engine and turbo to cool down with about 5
min of coasting, idling and/or sedate driving before shutting off the
engine. This diminished the chances of cracks developing in the
heads. That was a real problem with the OM621 engines. Finding 12
cracks in the head was not unusual in a car that was ridden hard and
put up wet. (one from each valve to the prechamber, and one between
the valves.) You can learn to control this also with an exhaust gas
pyrometer. I used an oil temp gauge. It was a lot cheaper.
That is my $.02 for turbo care and Diesel care in general. AFIK, the
turbo in my 412k OM603 was original. But I always warmed it up, and
cooled it down during my time, and I think the PO did too.
Actually, it won't hurt your gassers any either.

Hello All -
Was reading the tech section at the MB Owners Club site and they
talked about how different components have various life
spans. They talked of a Turbo having a long life if properly
maintained. Only problem is, I cannot find the maintenance
requirements of a turbo. Any idea what they expect to be done -
either by the owner or by a stealership technician to extend the
life of a turbo? .
Thanks!
