Diesel injector Wear. - Mike Humpherson
Refering to the Golf TDI, HJ wrote a few weeks ago:

"85K IS ROUGHLY THE MILEAGE WHEN THE TDI'S INJECTORS NEED REPLACING. THEY WILL CONTINUE TO FUNCTION AS THEY ARE, AND YOU WON'T NOTICE MUCH DROP OFF IN ECONOMY, BUT THE SPRAY PATTERN WILL BECOME PROGRESSIVELY WORSE, LEADING TO PREMATURE BORE WEAR BY 140,000 - 150,000 MILES."

My question is: Is this injector wear/bore wear problem specific to VW TDIs, or does it apply to all diesels?

I have a Peugeot 405 turbo diesel, which has an indirect injection engine. Should I routinely change the injectors after every 85,000 miles, even if they seem to be working well? If so, would having them cleaned or reconditioned be sufficient?

Diesel fuel injector performance is vitally important to the performance of any diesel engine. Poor injectors can result in incresed black smoke, poor starting and engine noise for starters. I would suggest having the fuel injectors serviced by a local diesel specialist who can be trusted - I imagine there are many cowboys out there. I can personally reccomend Electro-diesel (RCJ) of Sowton Industrial Estate, Exeter, Devon (Tel 01392 208090). I would pull the injectors out at about 75 to 90K and have them cleaned and serviced - beware some two-stage injectors cannot be serviced - only factory echange units are available. This shouldn't be a problem with your Bosch or Lucas CAV units. I would also reccommend using a diesel fuel injector cleaner every 6000 miles, added to your fuel tank. Personally, I recommend Wynns Diesel fuel injector cleaner.
