Turbo on D3 do they limp home?

[vbrab]

Have a slight whine in engine area (D3 2.7) that varies with revs when travelling slowish about town (new gearbox so shouldn't be TC).
IF it is turbo, does anybody know what is outcome if turbo fails? Do they limp home? can they be driven but slower?
Query is because I live remote and HAVE to do an 1800k return trip ASAP, and if turbo dies, need to know if vehicle likely to limp home.....or will I need to be picked up?
ALSO, anybody know what replacement options there are for turbo replacement? Can they be refurbished, or go total new, and are there aftermarket (Garrett?) options or LR only?

The first thing I would try is to turn the Climate Control system off, I had a whine in mine too when I turned the CC off the whine disappeared. Turned out to be the A/C compressor.

I would also check the power steer pump.
GOODLUCK

Thanks for that, will certainly check out aircon and power steering, but does seems very tied to engine revs and even when air is off.
Does anybody know if they do limp home if turbo dies???

The a/c compressor spins even when "off". It does not disengage a clutch, instead alters a flow control valve to recirculate most of the refrigerant within the compressor.

Belt idler pulleys are more likely to produce a whine than the turbo.

Depends what let go on the turbo!If shaft/bearings go,I doubt if it will be driveable,if actuator go the D3 will go into limp and you should be able to drive it with less power and some smoke.
My car had a whine that was related to revs,and turning the A/C off did make it go away.Another possible problem could be the alternator.Have it checked before you do your trip!
Good luck,

If the turbo bearings are worn you will be able to feel the resultant movement if you remove the intake side hose and try and move the turbine with your fingers. If there is any float on the turbine (either in and out or up and down) do not drive it any further. If the bearing or something else seizes or disintigrates the resultant debris will end up inside the engine with disasterous results.
It is more likely that something else is making the noise though. Check all the things that have been mentioned to exclude them first.
My money is on the belt tensioner bearing or the ps pump.
Hope this helps.

I think you mentioned in another thread you also had a new motor?????
If so check all the lines,ie gearbox,power steer.If a pipe mount was not re-fitted it could be simply a vibrating hose,especially steel ones.

Does it do it in neutral as well as when moving. Our youngest daughter picked a noise in our d3 but only at a certain speed , turned out to be passenger front wheel bearing starting to get noisy, drivers was fine.

Could be worth a quick check.

My D2 was the same before the alternator crapped itself.

Have just had ALL belts, idlers, pulleys, tensioners etc replaced on motor (front and back of engine, and full new transmission, and all 4 wheel hubs as well, and new alternator and water pump, and fuel pump.
(All in same service, just to be sure.)
Cannot be much left that could go wrong, but I'm an optomist.
The "noise" seems to vary with either the day or whether I use aircon, and I am starting to suspect the aircon compressor (thanks for alerting me Graeme) as vehicle has done 320K's and things are starting to be due for overhaul.
Still looking and listening.
