Cured the proplem.Off with the check engine light

👍 great!

2008 BMW 335i with the N54 engine, bought this to clear a 2C7B code (secondary oxygen sensor fault). The splice kit is really nice, it takes about 30 minutes to splice into the BMW connector, at a much lower cost! I put about 300 miles on the car since i did this repair and the code hasn't came back.

This will be the third of these sensors in the car. The original sensor and installation include a model-specific connector, and the need to pass that connector through a grommet in the tub. The grommet sits in an, um, interesting position that normally demands lowering the exhaust to access. Using this 15735 sensor allows me to pass another wire from inside the cabin, and use it to "snake" the cable from the sensor back inside, where it's very convenient to splice the new sensor cable to the original via a more common connector. It also saves some $$ along the way vs. buying the specific sensor from Porsche. I my 25-plus years with the car, these sensors have worked perfectly. The improvement in fuel economy alone pays for a new sensor in well under 50K miles. Doing the same math with the Porsche-supplied sensor more than doubles the payback period, effectively costing more than just the difference in sensor price. If you are comfortable managing the new connector install, there's a significant economic benefit in using this sensor. I've been religious in keeping the car to original spec all its life; I'm fairly sure no concours judge will ding me points for an extra connector in the sensor cable. Hasn't happened yet anyway. Buy this one and save money. Simple as that.

It arrived on time, was packaged well, and installed without any issues. The sensor is an OEM replacement, so I know it’s reliable and built to last. After replacing the old sensor, my vehicle’s performance has improved.

Felt like an OEM factory fit. Fixed the issue. Woks as intended for my 2006 OM647 2500 sprinter 2.7L 5cyl diesel.

Replacing either of the "upstream" heated o2 sensors (= lambda sensors) looks to be and should be a pretty easy job on most N51 or N52-powered BMW cars. You should remove the plastic engine cover and the whole cabin air filter/cowl covering, but that's about all it takes to get access to the rear bank o2 sensor that sits just below a little metal shelf/cover of sorts. The wiring for both sensors wraps around back of the valve cover and joins two connectors on top of it. I spent way too much time trying to remove that little metal cover just above the bank 2 o2 sensor because of a tiny rusted bolt (E8 Torx) caused by 17+ years of heat and exposure. Eventually I just bent the cover upward enough to allow an offset-style o2 sensor socket to slip past it with the cable in it and I was able to unscrew the bad upstream o2 sensor easily. With the little cover out of the way, the whole job should take you less than an hour to replace one, or maybe even both of these sensors on the N52 engine. The new sensor has some appropriate anti-seize on its threads already. After you install it/them, reset your diagnostic codes and you're on your way - my last one lasted 150,000 miles.

While this part fits perfectly both mechanically and electrically, it will quickly cause a P0130 (Upstream O2 sensor) error code. I will point out that this was the problem on my 2005 MINI Cooper S. Of course this part is shipped in a sealed bad that says "If this bag is opened, this part cannot be returned.) I was at my wits end trying to resolve this issue. I finally went to the dealer where the tech explained that pretty much only the factory O2 sensor works properly in these vehicles. While I was not happy with the price of the factory sensor, I was happy to finally get a sensor that works properly. In the photos the design of the actual part of the sensor that extends into the exhaust stream is shown. The Bosch sensor is on the right, and the factory sensor is on the left. Obviously I would have given this item zero starts if I could considering the number of hours spent trying to diagnose the problem.

Worked perfectly, allows the flexibility to extend o2 sensor wires to accommodate aftermarket headers and exhaust pipes with different O2 sensor locations than stock. Takes a bit of technical skill to install the supplied splice but nothing major.

Installer sur 323i 2007 très bonne qualité ajustement parfait sans problème très satisfait je recommande

Installed perfectly. Working as it should. Very satisfied .

Montato ,anomalia sparita 👍

Perfect fit
