2002 Audi a6, 1.9tdi - the turbo has died and needs replacing but am on a budget and am worried about buying the wrong part! Also any advice on the likelihood of thus not getting rid of the black smoke and lack of power?
The engine code is stamped on the engine but you can't always see it clearly. If you have the original service book it will be on a sticker inside the front page. Another place you can look for the same sticker is in the spare wheel well. It should be attached to the side wall of the well. If this isn't possible you can use the VIN number from the bottom corner of the windscreen. Telephone an Audi dealership and use the VIN number to identify your car. They will be able to tell you that and other information like paint codes.
It is most likely to be the 8 valve version.

How to find Audi Engine Code
Didn't find what the individual codes mean.
You may end up having to call an Audi/VW dealer.

hi turbos are not the easiest thing to change on any car firstly you can get recondtioned ones for half the price of the dealers one and it has the same warrenty but they are all funny about getting someone who knows what there doing to fit them as the problem with turbos is the heat they generate and need a good oil supply to them so they usually insist on replacing the oil pipes and changing the oil and filter and clearing all the inlet pipes of blockages and flushing the its oil cooler as for the catalystic converter the problem your fiance is going to have is that this is another item that gets that hot when you come to remove them the bolts and sensors are weled together and are very difficult to remove it all depends on how good at taking things apart and putting them back together he is best of luck yates210456

Have you taken a spark plug out yet? You may have fowled them out. if they are not clean and have a whitish tone to them, then they need to be replaced.
SOURCE: Power lacking
Blowing smoke when starting is not a problem this accours on all diesel engines
SOURCE: power loss and black smoke?
I had a similar issue to this after I got in a VERY small fender bender (literally) in an 87 Turbo Supra. In my case, my pasenger fender got pushed in JUST enough to crack a charge pipe and cause a boost leak.
Basically, what was happening was the turbo would spool and build boost, the mass fair flow sensor would read all this air coming in and tell the ECU to dial up the the appropriate amount of fuel. When the air reached the cracks in the charge pipe, it would escape out of them. Thus there was a much lower air-to-fuel ratio, causing less fuel to combust, which lead to power loss and black smoke out of the exhaust.
My guess is either an oxygen sensor, or more likely a boost leak.
Good luck mate.
