counterfeit bosch parts

[gorskined]

looks like they are counterfeiting the 044 pumps and wide band sensors and have been for some time. There are great videos on line comparing the real and the fakes.
I tried to save a few bucks , i bought three items from ebay over the past 4 years. pumps wide band sensor and a oil feed chain tensioner kit. Thank god all my internal parts were mostly nos or oem .
Two days ago pumps started making a high pitched squeal after about 100 miles and erroneous system pressure under a load. probably the main reason i have been having so many frustrating fuel issues trying to dial the car in ( everything looks perfect without a load) .. just ordered the new bosch 200 series pumps ( the new 044 replacement ) and a new wideband sensor form pelican.
now i have to venture into my thick ass receipt folder, something i said i would never do, to see what brand tensioner I bought and see it they are counterfeiting that also. i guess its ok as long as i don't start adding things up.

a standing tread on counterfeit parts and bad quality parts would be a helpful thread.

I bought some 044 pumps that I'm convinced are counterfeit, the factory seal on both boxes were cut open. This was like 3 years ago, so far they are still working but I have no confidence in the pumps. I guess they could be legit but what are the odds of both boxes arriving with both factory seals cut?

my pumps arrived in sealed boxed that looked totally legit as did the pumps. My wide band sensor same thing even had the hologram seal google counterfeit bosch 044 pumps there is a great video that compares the subtle differences.

While not necessarily a guarantee, I make a point to buy critical parts from reputable vendors. Pay a few more bucks for the peace of mind.

I bought from a place that has the Bosch recommendation of selling genuine Bosch parts. I’ll be way more careful in the future, any suspicious parts and I’ll immediately call.

I was given 2 counterfeit Bosch wideband sensors part of AEM WBO2 kits.

Bought a legit one from Autozone and all works well.

A month or two ago I bought an oil fed cam tensioner (via pelican). I could not mount it. The holes are out of alignment. Doubt counterfeit - just likely Chinese. Sort of amounts to same thing.
There is a recent/current thread on a DP porsche - they pulled the engine (rebuilt) 3 times to fix an oil leak. Turned out the new flywheel seal was not up to spec - twice. Changed to another brand. problem solved.
It is a crap shoot these days.
You almost feel like using your old parts if they still work even tho they may be bits that should be replaced..

100% agree.
This has been going on for years. Thanks to the OP for bringing back up.
I’ll have to check out the videos

spot on the lack of quality now a days sucks. i collect porsche hood crests i pretty much have every single one fron 54 to date. The early ones are amazing then you compare it to a new 996.. its like comparing a real police shield to a dime store kids play shield. the G series in my opinion were the last of quality crests.
I did use the the victor reins gasket kit always had good luck with them .i used a matched set of nos 3.0l turbo mahle p&C . My crank and original bearings were like new. i contemplated using the original bearings. as the machine shop didn't even touch my crank. and the bearings still had that gray exterior coating on them. i plasti gauged the old and the new they were literally identical. but i was concerned with delamination of the original bearing . i have seen that happen with old 356 bearings. so i used a new set of glyco bearings. surprisingly i have no oil leaks but i do have a to replace my catch can looks like there is a very small seep in the seam. not in any rush to do that. im sure i will need to remove the motor sometime in the future and ill replace it then .

When looking for a pump for my DP, I talked with Bosch about the 200-7. It is the replacement for the 044 pump which is no longer in production. They told me that virtually all the 044 pumps available now are counterfeit. There may be some NOS pumps around but, generally, any 044 you buy today is not a Bosch product.

The good news it that the 200-7 appears to provide a bit better performance that the old 044. However, if you are running any alcohol/flex fuel/E85, this is not the pump to buy. The Bosh tech rep stated that the pump life would be reduced by "more than 50%" and the warranty would be void if used with alcohol fuels. Here is a good summary from the Bosch Au site:

https://www.bosch-motorsport-shop.com.au/blog/tech-product-overviews/the-044-is-dead-long-live-the-bosch-motorsport-200/

I ended up trying out an AEM in-line pump rated for E85....here is to hoping it works out.

And, yes, I am the one lucky enough to install and pull the DP's drive train 3 times in 3 days to replace a poorly manufactured rear seal. What a PIA. Went through a lot of flywheel bolts that weekend.

lets hope it works I'm just using your standard 91 octane pump gas with 10 percent ethanol. so I'm told 10% e will reduce the life of my o-rings in my fuel distributor .. you cant win ... if its not one thing its another lets see how long i get .. sucks to hear about the seal issue. third times a charm.

This is a HUGE FAIL for Bosch, if they are not making it ethanol compatible!! Most of the people who will be in the market for these pumps will be running some sort of ethanol, from the crappy pump gas, all the way to E-100. That is just crazy that they would do that!!

I was amazed when I contacted Bosch and they basically said not to use their pump with alcohol. We are lucky enough to have 93 here but all of the stations locally have 10% ethanol which is enough to worry about our old fuel systems. When asked about only 10% ethanol, I could not get a straight answer from the Bosch rep about lifespan or warranty.

Crazy, right?

And here is a post from TK on the DP thread;
"Most any Victor Reinz rubber product is suspect."
Makes you wonder where to turn. You have to feel for engine builders having to sort their way thru this crap.
I found a 2nd hand older 044 pump f/s on a local trade website and jumped on it. As a spare. Then it got lost in the post. The post service offered me $s compensation. I said no - it is irreplaceable, i need the unit, not the $s. They finally found it. Amen.

according to bosh their o rings in their fd are non compatible and have never been compatible with alcohol / ethanal . my 74 911 ran 250k miles with the low grade 10 percent ethanal fuel with the original o rings in the fd without skipping a beat. as did all the other 911's on the streets . i believe that statement is basically a cya for Bosch against the high winter blends the e85 and the flex fuels ... time will tell

Maybe it's a CYA kind of thing... But to think that E-10 to E-15 is pretty much everywhere and commonplace now, and they are still saying that? Kinda crazy. If I were them, I would source the right parts to make it work. I would be willing to pay for it in the price!
There are o-rings that are compatible, but they have chosen not to use them? Or, at least not come out and say that? Yea, I use (2) 044 pumps, and do run E85... they have lasted so far. I sourced them from Chris (TK).. he had a supplier that he could get the good ones through, but that was 2 years ago... I guess that is now out as well. Since I am EFI, I guess I will have to go with another manufacture and change brands, when mine do finally fail.

I’ve been running standard pump gas, which I am assuming has around 10% ethanol for around 125000 miles now with no noticeable issues in my 86 with the aluminum FD. Just rolled over to 157,000 miles this week on a 750 mile trip. Original engine with bolt on’s.

I recently bought 8 iridium plugs for another vehicle of mine. They were in sealed OEM boxes from the car manufacturer but did not have a cellophane wrapping. Plugs looked nominal out of the box, but they lasted about 100 miles due to center electrode basically disappearing. Previous plugs had 100k miles on them with no problems. Tossed the bad ones, bought new ones from dealer, and all is good once again. A first for me in 50 years of working on my cars.

curious if you addressed it with the vendor and got a refund
