1.9 TDI/AWX - injectors lifetime

[dpetrov]

Dear colleagues, i'am wondering did you know what is approximately lifetime of pump-duse injectors? I have seen a commercials in mobile.de and autoscout24.de for vehicles with +350.000km with pump-duses in good and working condition. So i'm curious about the strength of this engine. I had an Audi B5 with AFN engine which was really good, and i was heard that it can run more than 500.000km without any problems. Thank you for your time!

I have heard it said that the injectors are good for about 100K miles. I did find this a bit of a surprise as I thought it would be considerably longer, bearing in mind the cost of replacement injectors. I would ike to know the life of a PD injector and whether anyone services them ?

They used to fail but that seems to have stopped. These days they are very reliable.

Mine is on 150K almost and so far, it's still on the originals.

I changed one on 148K, today it seems that I have to change another one on 152K.

Well all this sounds good... I'm on 52k so they've got a long way to go!

Does vag-com tell you when they fail?

I actually work for a company that makes PD 'type' injectors for the large 16l truck engines, and we warrent them for 1,000,000 miles.

i would say the bosch pd injectors should be happily lifed to 500,000km

If it's a mechanical fault, it doesn't tell you, it has to be an electronic fault.

The scan showed only Cylinder 3 misfiring

Does anyone know that once you change an injector, the others have to be changed as they will have different amount of pressure/stress on the system which will cause them to fail as old injectors?

[Crasher]

It is OK to change one injector, the ECU will compensate for slight differences in flow, especially at idle.
