7 volt steel glow plug's available?

Brian's96TDIPASSAT · Jul 1, 2015

Has anybody sourced steel 7 volt glow plugs for these PD engines. Most of which I find is either 7 volt ceramic or 5 volt steel and wanted to avoid the whole dealer re-flash for 5 volt is at all possible. BTW, I did search the posts here and didn't find any posts say after 2011 so maybe somebody has figured it out.

The newest plug is an NGK 7v, part number is N-105-916-09. Note these are NOT the same 7v NGK plugs that the BRM uses. These are ONLY for BEWs, BHWs, and BKWs, to replace the original Bosch 7v plugs (as a set).

I have no idea what it is made of.

I've been running the 5v Bosch in mine for the last 90k miles without issue, with an RC1 tune that included the part for the 5v plugs.

The stock original software (unmolested) works fine with the 7v NGKs just as it did with the original 7v Bosch.

I installed a set of these new NGK 7 volts a couple of months ago and I shipped the ECU back to Rocket-Chip for the needed adjustment for the new GP's. Car starts great now !

thanks, I think the NGK's are ceramic but I never have had any trouble with the ceramics in My 05 Passat so I'm guessing this engine I'm putting together for somebody won't either. I was hoping for steel but as long as they'll work with the stock ECU he should be fine

The newest GPs (the NGKs) are hybrid - Steel/Ceramic. OE were ceramic 7V and there were a lot of failures and pooched engines. The first recall was the all steel 5V GP, followed by the current hybrid 7V recall.

I suggest replacing the old ones as they can get stuck and sometimes broke. No is the best time to remove them while rebuilding the engine

Reviving an old post... If my car has never had any of the 2 GP recalls done, do I still need an ECU re-flash to change from the original GP's to the ceramic/steel hybrid NGK's or can I simply remove the old GP's and replace with the NGK's? *knock on wood* I don't have any GP problems right now; just trying to be proactive towards any winter problems (and peace of mind).

No you swap with out a software change.

Print out OH's how to on changing the GP's.

Good luck!

I've done a search for a 'how-to' relating to glow plugs that OH has authored but I come up empty.

Question on N-105-916-09, is this a real product at 11$ each? I need to change the harness on these and may try to change the GPs. Nice write up I get the P0672 error code about 20% of the time (clear it with scanguage) and I am hoping it is just in the harness, which is cracked. I have had the car from new, and never followed up on the GP recall. 86 k miles at this point, manufacturing date 12/04. TIA for any wisdom.

Edit, I will check the resistance of each plug once the harness is off. If they are all good, any opinions on just leaving them in? Any way to ID them without removing them? I do not plan to drive this car more than another 20k miles total over the next four years. More thanks.

Another edit, since this is the BEW, yes, I have always had 505.01 spec 5w40 oil in it, change intervals around 7k.

Is yours a Passat? If yes then it is BHW engine. I can’t recall if the original GPs were 5v or 7v. I know there were 2 software updates and the latest uses the 7v GPs which is the # you have listed. If you scan the ECU and post the part # we can tell which version you are on.

Hey vwz,

2005 Jetta GLS, like your Passat but a few inches shorter. BEW engine. I have never been back to the dealer, so I am assuming that it is the as-built ECU software version, which I believe was 7 volt. I am just surprised to see such a wide range of prices for the NGK part. $11 only makes sense (to me) if there is excess stock out there and sellers are trying to move them--or there are low quality fakes out there being sold. So that is my first question, is $11 for this part reasonable in 2023 or steer clear?

I believe the NGK 7 volt is the correct drop-in replacement part for the original 7 volt ceramic. My second question is whether I should just leave the original as-built GPs in there, or try to gently get them threaded out and replaced. I see information out there that they are fragile and can break off in the engine, and that they are fragile and can break off during removal. This state is in some ways a metaphor for other parts of my life these days.

Right now, starting the car, there are no GP error codes. I am assuming the intermittent GP error codes would be traceable to a bad harness, and that an always GP error code upon starting means a bad GP. So that is another question, can GPs themselves throw intermittent error codes like I have seen for the past five years?
