35d: 40mpg, try to pass, engine dies - Page 2

torqueisking · #11 02-03-2016, 07:50 PM

Drove 15min to lunch today, no issues. On the way back, engine dies. Restarted and kept driving 4 times until it finally wouldn't run. Didn't want to call a tow truck so I disconnected the #5 injector electrical connector because the codes confirmed a short circuit. It ran rough but I drove it home.

Resistance across the injector pins should be apparently between 170K and 210K ohms. While mine measured 210Kohms, the resistance between one pin and ground was 5K. The other injectors measured higher than my meter could read.

Took off the intake and tried to remove injector #5. Of course it is seized. Soaked it down with a penetrating lube. Hopefully I can remove it in a couple days.

While I'm in there, the intake manifold (including flaps) will be cleaned. There is about 1mm of CBU. Not too shabby for an M57 at 90K miles.

You are resourceful, I like it!!!!

Most tools I've seen to remove the injector attach to the body of the injector by removing the solenoid. There's picture of homemade tools that go this route and you can get crafty. Alternatively, they have them on ebay and you'd still be ahead than paying someone to do it. You could also try to crank the engine over with all the injectors disconnected and see if compression pops it out...

You may know, but the new injector will have to be coded. The car is derivable but it may throw a code either immediately or as it tried to run the zero quantity adaptation. If you don't have the tool to code it yourself, take a picture of the injector labeling and/or write it down so you can give it to the technician

Thanks for your updates. I got the codes 4b99 and 438d with stalling and restart fail. Power down wait minute, restart OK. Misread the 4b99 code as injector 2 when it meant bank 2 (aka 4 5 6).
It just got worse, until I couldn't get home.

I had removed the foam when i did intake cleaning and fitting a ccv oil separator which required houses across the top. I didn't notice the crack there until reading the bimmerfest thread: Error code 4B99 and 483D - Bimmerfest - BMW Forums
57 dollars for piece of crap plastic... hmm
I dont trust the replacement even, so this looks interesting Engine compartment bulkhead plastic/rubber partition flexible epoxy repair - Bimmerfest - BMW Forums

Corrosion is funny where issues can crop up a year or 2 later, like we had with hurricane Sandy on underground electric lines exposed to risen salt water.

The other day I took the manifold off and tested the injectors to ground. 1 to 4 beyond meter can read.

6 - one pin 250ohms! Other 20kOhm
5- 150k / 20kOhm

Originally I ordered one injector but luckily the eBay vendor didn't ship yet so I added another to the order. $360 new each, using the Bosch number
0445115077 for search, verifying the pictures and other part numbers for 335d/35d.

Sprayed a bunch of kroil around both injectors to soak for removal. Hopefully they come out easy, then I'll clean the bores with a vacuum and narrow hose. I've done injectors on my past VE TDI, so I'm not concerned. Coding I understand can be done in ista Rheingold.

What tool are you using to remove the injectors?

How did you test the injectors?
Step by step (with pics) would be super helpful to me (maybe post in DIY thread?).

I get blue smoke on cold starts, as well as sooty tail pipes.

All points to unburned diesel as likely causes, and thus faulty injector(s).

Also, in Rheingold, saw 4590 code (DEE: Rail-pressure plausibility delivery-controlled) a couple weeks back.

Sorry no pictures today. It was on and off rain so I had to rush the job. I tested the injectors electrically by disconnecting the plug, setting a meter to ohms, clip one lead to ground, a bolt on engine perhaps. Other lead touch the pins inside the injector connection. If you havent used a meter on funny plugs its kind of tricky to find the inside pins. Your code doesn't sound like the injector wiring fault though. You could have a sticky injector, who knows?

The rail pressure code could be a leaky injector? I don't know enough yet about these cars, I had a TDI before this which was so much simpler.

To remove the injectors my friend welded me what this guy used: DIY: 335d M57 Fuel Injector Replacement
A good DIY on removing injectors and replacing. Just make sure to soak them, makes it way easier to remove them, and even then my number 5 injector was hard to get out!

See the link i put in my last post for the tool to make.

Anyway runs good but ista d /Rheingold doesn't want to save my injector code! Says not o.k.
Below that it said use aaaaa5g if the code doesn't work. That saved over my old values for 5 and 6. Anyone have an idea? I'll try tool 32 tomorrow, just annoying weird stuff like this spooks me.
