how can you determine what revision injector you have? Mine have what looks like an 09 cast into them. Is that the year of manufacture? Is that how you tell or do any of the other numbers mean anything

the numbers do tell you the year an month they were made, and what motor they are for, my aunt works for bosch and she deals with injectors all day long. I dont remember how to read it even though shes told be about 20 times already lol

Ok so which numbers mean what:confused: theres about 8 different sets of numbers on there! Does the cast number kinda up by the high pressure fitting mean anything? Mine have what looks like an 09 cast into them and I thought that some i seen had an 05 cast into it. Is that the year?

list all the numbers on there as they are listed on the injector on here. Theres like 3 rows iirc. i know the big long one determines the year made, month and what motor
looks something like this...

xxxx (xxx)
xxxxxxxxxxx
xxxx xxxxxx

it will be on the side of the injector where the hold down would go. i would call my aunt but shes working.

99118 5167
8972080 745

that's the numbers on mine. Thanks a bunch in advance:hug:

My last set only lasted 35,000 so i'm just a little wary putting just anything in. I was told there was a fairly recent revision and I want to make shure these are it. Whats really bad is my original set lasted 165,000 and these were supposed to be a "new and improved".

Bump anyone? The dealer doesn't seem to know what this means. Is there anyone I can call that would know?

That is an 09 injector. The third row of numbers is the date code. The first five numbers tell you that it was remaned 11-18-09.

can someone direct me somewhere i can figure this out

I told you in a previous post on how to read the date codes. It will be the first five numbers on the third row. The first number is the year the second two numbers are the month. You will subtract eighty from those numbers and get the month. The last two numbers will be the day. Example (99022) nine is the year, ninty minus eighty will be ten (the month) and twenty two will be the day of that month. Hope this helps you out.
