BOSCH 0261210170 Original Equipment Crankshaft Position Sensor

I love the product... Genuine Bosch for a fraction of the cost of the Genuine Bosch that has Bosch numbers on one side and a three pointed star on the other. I bruised the heck out of my hand reaching the sensor and getting it out and reinstalled as it is a very tight fit between the firewall and cylinder head. But, the savings over taking the car to the dealer was huge as it would have been $500 with them. Be sure to have your E8 star socket, long extensions and U joint extension. Once installed and torqued properly to 8 N-m (per the Benz service DVD) I cleared the code and the car is running great with no more long crank times to start and no more check engine light. The product is great, but I have a couple gripes about Amazon on this...1) I ordered relatively early on a Sunday and paying $3.99 extra for over night shipping was not offered as it usually is with Prime. Instead, all that was offered was my "Free Two Day" shipping which didn't have the item delivered until Wednesday. So, my car had to sit for 3 1/2 days waiting for "Two Day" shipping. With Prime it is odd how sometimes Sunday counts and sometimes it does not. And, 2) The Amazon fit list is incorrect. Amazon says that this items does not fit my 2005 E500 4Matic. In fact, it does fit and is an exact match. I removed the old sensor and found the correct part number based on the actual part. The actual part has a Bosch number on one side and the Benz part number on the other. The Bosch number was 0261210171. By cross referencing that number through Bosch and other parts sites as well as looking up the Benz part number, I was able to verify that indeed ...70 was a proper replacement for ...71. I have no idea where Amazon is getting their fit data, but the fact that all the other sites show it as the right part both as replacement for the part and the right part for the VIN, it is clear Amazon is getting some bad data.

Replaced this in my 2005 Chrysler Crossfire six and a half years ago. No problems since. It was a bit tricky to reach, but I have absolutely no automotive mechanic experience whatsoever and I was still able to do it myself.

My car wouldn't start once warmed up, it just kept cranking and cranking. Thankfully, it never left me stranded because after letting it cool down for about 15 minutes, it would start right back up. Got home and used an iCarsoft MB II scanner and got fault codes of P0335 & P2034-008 which is the Crankshaft Position Sensor on a 2005 Mercedes SL500 with 92,000 miles. Found this part on Amazon and managed to replace it myself with minimal difficulty. The sensor is located all the way back on the driver's side of the engine where it connects to the transmission. It's right next to the firewall and about 6 inches down. There is not much room for your hand let alone an E-8 Torx socket, extension, universal-joint and ratchet that you will need to remove it. I ended up removing the air intake tubes and housing. Also a little bracket that secured some wires with a zip tie was removed before I finally found the sensor. All in all, the job took 1 hour and 15 minutes. Good luck!

Keep Your Mercedes Running Smoothly. Replac with OEM BOSCH Crankshaft Position Sensor A Guide to Replacing the Crankshaft Position Sensor Does your Mercedes (M112 V6 engine) sometimes stall and refuse to start until it cools down? You might be experiencing a faulty crankshaft position sensor (CPS). Here's what you need to know to keep your car running smoothly: What is a Crankshaft Position Sensor (CPS)? The CPS is a vital component that relays information about the engine's crankshaft position to the car's computer. This information is crucial for proper engine timing and ignition. Symptoms of a Failing CPS: Engine stalling and difficulty restarting (especially when hot) Rough idling and engine misfires Check engine light may illuminate (although not always) Why Replace the CPS? A faulty CPS can cause a variety of problems and leave you stranded. Replacing the CPS is a preventative maintenance step recommended between 80,000 and 150,000 miles, even if you haven't experienced any symptoms yet. The Good News: It's an Easy Job! Replacing the CPS is a relatively simple task that can be done in under 10 minutes with the right tools. Here's a simplified breakdown: Location: The CPS is located behind the exhaust and on top of the bell housing. Accessibility: You can conveniently access it from the top of the engine bay with a 30-inch extension and an E8 socket. Removal and Installation: Masking tape can help prevent the screw from falling during installation. Remember, replace the CPS when the engine is cold to avoid burns. Recommendation: Replacing the CPS is a straightforward DIY project that can save you from a roadside breakdown and keep your Mercedes running smoothly. If you're comfortable with basic car maintenance tasks, this might be a job you can tackle yourself. However, if you're unsure, it's always best to consult a qualified mechanic.

I think that Amazon's parts catalogue erroneously reports that this is not the correct part for the 2004 MB E500 4Matic. I looked at the Bosch online catalogue, which specifies this part number as the right one for my car. I think the issue with the catalogue is that this is an upgraded part from the original Bosch part, which had a different part number. Amazon doesn't recognize that this is the replacement part for that Bosch part. I bought this part from Amazon, instead of paying $170-ish at the dealer, and installed it myself, instead of paying the dealer $400 to do so. Net savings: $530. There are plenty of youtube videos that will show you how to replace it. My own experience lets me give this advice. Do it when the car is cold or cool, so that you don't burn yourself and you can lean on the engine when reaching over. Use your fingers to find and identify the part. Visualize it, because you are going to have to do this without looking at what you are doing. Most important: don't drop the Torx bolt once you unbolt it, because you will never get it back. That requirement slowed my progress, but it all went smoothly. Basically, the process is just: (1) find and unclip the connecting wire by squeezing the top, remembering the orientation and what it feels like; (2) get your torx socket (E8) on the bolt, which is in a weird location; (3) unscrew the bolt, not dropping the bolt; (4) wiggle out the sensor, which is hard at first but wiggle enough and it will come right out; (5) insert the new sensor, some people have smeared a little oil or wd40 on its shaft so it can be turned once in the hole, where it is tight, (6) make sure it is properly oriented so the bolt hole on the sensor is over the bolt hole in the car; (7) insert bolt and tighten; (8) clip wire back to sensor. Done. Now start your car and be happy you just saved $500+. The videos make this all clear. I used some paper towel to wipe off the area above and below and around the old sensor before removing it, so dirt didn't get in the hole. Good luck!

If you're looking for older or classic car parts for your Mercedes, it's best to used their website for old and classic cars. I've purchased at least four crankshaft position sensor and none of them work. The prices are more expensive but it's worth it. Saves time and hassle. Thank you.

Excellent Part, thank you

Es original. Lo unico que vi que el sello del precintro benia abierto, pero puede ser por que la caja es de carton fino y puede que se rompiera la pegatina. Por lo demas perfecto

Avoid Chinese knock-offs and the cheap brands. for this item only genuine items fit. now starts and runs on the button.

Perfetto per mercedes r230!

Dit Bosch product is identiek aan het Mercedes onderdeel A 003 153 28 28 maar veel voordeliger in prijs. Als uw auto ca. 200.000 kilometer gereden heeft is het raadzaam dit onderdeel te vervangen. Als uw auto bij koude motor goed rijd en bij warme motor minder goed, of bij lange ritten zelfs uit wil gaan of helemaal niet meer wil starten dan kan het aan deze krukas sensor liggen. Zeker de moeite waard om te vervangen.
