Thread: 300tdi Injectors

c'mon 31 views not one answer?

ive had a look at previous posts I always do. if i start a new one it means ive already searched and could not find.

If you were to get new nozzles then you would have to send them away to get them fitted/tested I assume.


I would just get new injectors and slap them in.


But in saying that, I've got 220K on the clock and not even considering new injectors.




What is the life span of an injector ??????

Oh and why does the price of the injectors vary so much.


Must be some YUMCHA brands out there.

If I was suspicious of one or some of my injectors, I would get another similar aged secondhand set, then go to a injector service business and ask them to test the lot then choose a balanced set of four out of the best of them.

Discard the faulty ones as they are not repairable.
.

Generally.

Don't bother with testing the tdi Injectors, they are a two stage injector and the cost of testing alone goes close to the cost of replacement, if they come up off spec adjusting them will typically blow out the cost.

yea when you look them up there is generally a fairly cheap set of imitation ones and the bosch ones.

the prices i quoted were for bosch full injectors and bosch nozzles (just the end bit). that is the price difference i meant and one of the questions i was asking regarding just replacing the nozzle part of the injector. it doesnt seem like a difficult job to just replace the nozzles.

some injector places i asked here test the units for free. if they are stuffed then they just get a whole new unit. they dont bother playing around with them. which is why i was wondering if its worth getting the nozzles put on the end.

You could go the middle ground, you can hook the injector up outside of the engine and give it a quick turn over and have a look at the pattern with the Mk1.
If you don't like what you see then get a new set.

note I haven't done this myself, I would assume that it is a two man job, one to crank and one to observe and for the other person to basically turn the engine off straight away.

Don't have fingers in the way, eye protection, etc. etc. do one at a time and point it at a rag in the engine bay.

I guess the only thing is, if you find one that looks rubbish are you just gonna buy one?
For the faff I'd probably just buy a set and change...
