	From the message, I deduce that this is more or less an '83
	4000 turbo diesel, for us US listers. Presumably the same
	I-5 turbo diesel in contemporary 5K's sold here.

	You're clearly in India (wow, cool -- you're the first lister
	with an Indian e-mail address), but where's the car?

	It's probably very similar to the VW inline-6 turbodiesel that
	I had in my Volvo 740, in which case the turbocharger is a Garrett
	T-23 (25?).  It's possible to get a replacement cartridge for about
	USD $350 -- which consists of the center housing and the impeller/
	compressor rotor, inside which the offending oil seal is. The
	procedure is not difficult, though you do have to be careful
	not to damage the vanes in the turbo.

	Frankly, it's highly unlikely you'll receive anything from Audi
	but a polite letter. It is indeed strange that the turbo died
	so early (mileage-wise), but you don't say what kind of driving
	was involved.

	If the car is in India, you might try newer truck repair shops
	that may have some experience with turbo diesels (I saw several
	Isuzu turbodiesel trucks when I was there last). Otherwise, your
	best bet would be to find a reliable mechanic, get the shop
	manual, import the replacement cartridge (perhaps through someone
	visiting the US) and have at it.

	My shop manual (for '84-88 5000s) has a lot of stuff about the
	turbodiesel engine -- if it's similar to the one in your car, I
	may be able to photocopy sections and send it to you.

	Good luck!
