Injector Replacement

EvanTheBruce · 01-22-2017, 05:37 PM

Hey guys,

I'm in the middle of replacing my injectors right now. I noticed a ton of dirt that was built up inside the injector holes in the head. Dirt even made it past the seals on the injectors. I cleaned out the holes and blew them out with an air touch.

When I put my new injectors in, they stick out about a half inch longer than the previous injecotors. The part numbers are the same and the injectors are the same length. I tighted down the caps to spec and they still stick out. I've tried tapping them in with my slide hammer but they will not go in any farther.

Is this normal? What is the solution to this? Keep banging them down?

Thanks for the help as always!

Did you put some oil on the seals before installing? are the hold down flanges installed on the injector before install? Mine went right in.

DozerD, where you at in NJ? I may have to bribe you some day to help me replace mine. Got another code 200 miles or so ago, with clearly a noisy injector. Went away with half tank triple dosed with diesel kleen, but thinking I may be on borrowed time.

Are y'all finding a good deal on injectors from somewhere? The cheapest I find is $500 a piece, and $3k seems like a crazy amount of money to spend on injectors. I get that I'm in a very "pay-to-play" vehicle, but still. Is there a cheaper option anywhere?

Dead center in the state. 10 minutes off exit 8 on the turnpike.

They are not 'too' bad to do.

That is about the best I have seen them for. I lucked out and bought 4 used ones from a member here for a killer deal, it was kinda of a gamble but it worked out!

My car sat for 10 months because I refused to pay that much for them.

I have a few that tested bad that I am going to try to get rebuilt (at some point)

Euro eBay has yielded some good searches when I looked.

With my dealer pricing I got my injectors for $580 a piece, all together with taxes it was about $3600. Warranty covered it though and I'm adding secondary filtration like TDIwyse did. If you need new OEM injectors and decide you are willing to pay the $580, let me know and I will order them for you.

I oiled the seals but put the caps in upside down.

EvanTheBruce · 01-23-2017, 08:21 AM

Without starting a new topic, does anyone know a good place to have the old injectors tested/rebuilt? There is a shop local to me on the North Side of Chicago who can test our injectors but they are unsure if they can be rebuilt/cleaned. I'm assuming that the Piezo solenoid fails in these over time from wear and tear but I could be wrong. My car did not throw any codes when my injector failed. I diagnosed the injector as being bad by pulling the electrical connection while the car was running. I forgot to Ohm test the connections when I had it out with my meter.

Curious if you are running a BPC tune? That is second instance I've heard of with bad injector(s), but no code. Johnnybravo had half his injectors needing replacing IIRC.

Mine (JR) has been throwing a injector code code lately, but only symptom is that it gets noisy after code is thrown and quiets down after a bottle of injector cleaner. Reset SES and stays away for a few K miles until it pops up again...usually after a very spirited run. No loss of power, rough idle, smoke, etc. Perhaps I have to look at resetting adaptations.

Hey Guys....

Okay through my trials and tribulations...

Thing 1. For testing, find a diesel shop with one of these: EPS 200 Its the same device that Bosch uses on the factory floor. The tester hooks up the connections (fuel, overflow, electrical) and hits a button, then the machine runs a diagnostic....they cant screw it up. And you get a full read out of ALL the specs...

Thing 2. I got my injectors from
Sprinter Supplier......they are a wholesaler so they can sell super cheap comparatively...but not directly. They have an ebay page where I got mine for $365 each.
Heres the ebay page: http://stores.ebay.com/sprintercentral/
And the item if it hasnt expired and they have a new one posted:
http://www.ebay.com/itm/NEW-OEM-BOSC...item41b64c43b7

Good luck (to me as well, I have at least 1 failing one right now)

If it makes you feel any better, in my excitement to get mine back in and running (or maybe it was the beer) I left my caps off.

I spent 20 minutes writing down every number off each injector, what position it came from, where it was going back in etc, then put them in...

Went to put the hold downs on and was like errr, umm, hmmm... woops

It happens.

Yes, I am running the BPC tune. I spoke with Randall on the phone and he said their programming should not affect the stock error codes. It's weird because when I pulled ghost codes on my car I got a bunch of AC and ABS errors on my car that don't exist in the BMW database, despite my AC and ABS working perfectly.

Well shit dude, great find! $365 each is cheap compared to OEM. I found a shop near me with this machine, going to send my old injectors out to see which ones I can keep on hand for replacements if I run into issues in the future.

Are you using ISTA D pulling codes? I didn't have any AC or ABS codes. Did you get the
Injectors to register?

Yeah I got everything taken care of! Thanks for the help dude!

I pulled those codes from my buddy's snap on computer. It communicated just fine with the car until I tried running the ABS pump and lift pump for fuel functions. Didn't activate as it should. That's why I was trying to find ISTA software for my car.
