hi all.
my first post here but bear with me
got a vw sharan with a 1.9tdi 110hp afn engine, it dropped a valve last week and ive redone the head but it needs a new nozzle.
i know that my car uses DSLA150P520 as standred which is a .205 nozzle, my mate give me a set of new nozzles but are marked DSLA145P619 everything looks identical on nozzles but what are they and better still can i use them.
many thanks for any info as its a shame if i cant use them

Yes, you have .205 nozzles stock. You should get .205 replacements. Even if they look identical, unless you have an electron microscope, you won't see any difference. Take a look through this for some basic nozzle FAQ

it doesn't list the 145 P 619 but I can tell you that the "145" means that the spray angle of the nozzle is wrong. It should be 150. I don't know if it will work correctly because the nozzles are supposed to spray into the recessed swirl chamber on the piston head. In the best case, it may run okay but not as efficiently. In the worst case it will melt a piston by causing hot spots. This is just a guess.

I don't know what they are from, but all nozzles used on your engine should have DSLA 150 P , and then the part number.

Shoot these guys a call or email, not sure which language you want since it's for a sharan:

They make replacement nozzles and they should know what the 619 nozzles are, IMO, those new nozzles are bosch because of their part number but you have no way of knowing what they really are since the part numbers don't go up as nozzle size goes up, 619 could be smaller or larger than what you have. I would not use them without finding out more info first.

How would it melt a piston? Is the pumpe duse have this problem since it uses a different nozzle?
