Bosch 0281002461 Original Equipment Mass Air Flow (MAF) Sensor for Select Volkswagen: 2004-05 Passat, 2004-08 Touareg

My 1999 Audi A6 2.8L had been idling high and rough for some time, with bad mileage. It warmed up slowly and then threatened to overheat going "over the hill" and I was worried about the new water pump. Then I started having trouble restarting when hot. It finally threw a code for this part when I was trying to start it so I researched online on my phone from the car. Within 15 minutes, I ordered this part and it arrived in 2 days.The new sensor was easy to find and install, but the first time I tried, I didn't understand the spacer was removable and the sensor fit into the hole too far. Luckily, I knew from other reviews this was possible and I turned the key off as soon as I heard a horrible screech from below my feet. I reinstalled the old one until I looked up the spacer and realized that something I assumed was part of the old sensor needed to be pried off and reinstalled with the new one.Once I installed the new sensor, it idled smoothly at the usual RPMs, got its mojo back for acceleration and hill climbing, and stopped threatening to overheat. Started easily and reliably too.This is super easy to install on models of VW/Audi that share the same drivetrain as my car. (I'm familiar with the VW Passat and Audi A4 & A6 with the 2.8L engine, automatic transmission 5HP19. Could work for other related models too. I'm not a mechanic, just a DIYer on *this* drivetrain.)On the 5HP19 transmission, this sensor is located a few inches from the left axle heat shield, up and to the left about 10 o'clock, attached with an 8mm bolt. You can access it with the car lifted safely and the wheel removed. The connector is up on the front of the firewall near the O2 sensor connectors (I think it's gray). The cable winds through the electrical spaghetti up there so you might not be able to route the new one the same way, but as long as you don't let the new cable rest on the exhaust and melt, you'll be fine.

Having recently changed the battery in the trunk, and after driving 30 some miles, the crank sensor decided it was time to die. Vehicle mileage is approximately 75,000 miles. Thankfully, the car was being serviced when it died. This sensor works. The location is in the closet to the driver side and it can be removed by feel with a torx E8 socket and extensions. The screw is small, so be careful not to drop it. A reset of the ECU and you are good to go. A mirror on a stick was helpful for screw alignment but be warned it is very difficult to get a complete view of the screw to hole alignment. A little motor oil should be used to lube the sensor before insertion. I avoided the less expensive options, just not worth the experiment.

Bosch was the OE, and you can buy the Porsche name and pay the brand tax or you can get the same part for half the price. Not a fun install so replace both sensors and the CHT sensor while you’re at it if using on a Carrera 3.2I read about these on Pelican, I believed, I installed myself, and the car now runs as it did before the issue. Proven.

This Bosch part for the fuel rail sensor on my 2005 Ford Expedition 5.4L V8 was an exact fit and easy swap. My car was coding that the fuel rail sensor was reading high and so far this seems to have fixed the issue. At the local parts house the cost was over $125.00 got it here for $30 something so almost $100 savings. Just goes to show what shopping around can save you.

Bought an off brand that was DOA. The fuel temperature sensor function did not work. Boy, I hate doing the same job twice. Spent twice the money and bought the Bosch brand. I did not have to worry about this one working. Like a Bic Pen...works first time, evert time. It even said both "Bosch" and "Ford"on it. Evidentalially Bosch makes these for Ford.

I ordered this before finding a intermittent vacuum leak. Decided to keep it and monitor mileage. Did same route and close as possible same speeds and cruise control on freeway. Saw a mechanic state on here these MAP sensors get updated. Compared to stock 2007 C230 Sport MAP, I’d have to agree! I got anywhere from 1.4 to 1.7 mpg more! Same fuel Chevron Supreme. Did multiple tanks on old and new MAP. This will pay for itself. Car idles better and acceleration is better.

Had P1135 code, Heated O2 sensor Bank 1 Sensor 1 Heater circuit low input Code. Once this was installed, car runs much smoother and should keep the light off. II was lucky enough to get an open box one from amazon, so got a pretty hefty discount making this a great value too.

Purchased this sensor to replace my failed (heater circuit) sensor in the upstream position of my 2006 Subaru Tribeca but upon installation I got a (low voltage) code. Reinstalled the old sensor and ordered a Denso 234-9047 and it worked fine.Amazon compatibility chart showed this should have worked.So either the new sensor was defective, the part box was mis-marked, or the compatibility chart is wrong.The quality of the part looked good.....but a lot of extra work for me...****EDIT****: I received the Denso replacement sensor and it worked fine in my 06 Tribeca......So, there was definitely an issue with the Bosch unit.

After getting performance issues with my Golf and reduced mpg I swapped the MAF (Mass Air Flow) with a known working one and the performance was restored. The issue I had was when the engine was cold there would be hardly any power up until about 2.5k revs then all of a sudden a lot of power. The fuel filter and glow plugs had also been changed as these needed doing anyway. This Bosch replacement is the exact same model number removed from Golf, the only difference is this new one doesnt have the Audi / VW logo which is fine. Amazon was the cheapest place I could fine a genuine Bosch one, I called VW just out of interest and they charge £140 and they need your old back as I assume they refurbish them. So I feel this was a bargain at just under £80 from Amazon direct (not a 3rd party seller)

2005 Volvo s40 2.4i petrol struglle few times with start, didn't always run smooth or sometimes bit lacking power.After failed attempt on start Engine Check light came onPurchased OBD2 scaner and error code was P0190 Fuel Rail Pressure Sensor A Circuit.Quick search on google for people experience and it was possible that sensor could fail or its wireing or somthing with fuel pressure system: pump etc. But most people changed sensor and problem went away. Had a look around wires all seemed ok. I have purchased this one because it is exacly the same part number as original one on car even if amazon says it isn't compatible with my car. Sensor came next day it was identical to the BOSH one on car apart from missing small volvo logo. Replacement very easy. Undo plastic colorful cap on righr side looking aft from fuel rail. Put cloth underneath and using screwdriver press tyre like valve to release fuel pressure. In the left side looking aft gently unclip and slide timebelt upper cover for access. Undo electric connector. Put cloth underneeth sensor as some fuel will come out. Undo 1x T25 torx bolt holding sensor and wiggle out old sensor. Install new one. Connect electric connector and timebelt cover. Start the car. Car worked perfectly and problem went away. Time for cup of coffee.Did now nearly 2000 miles and problem didn't came back.

Extremely pleased with this purchase for my 2002 VW Passat 1.8T. It is almost one fifth of the price from my local garage - but is exactly the same product! I was a bit dubious at first, but I searched on the Bosch website for my vehicle model number - and up came this part number. So I was confident that it was the correct part, but thought maybe it was manufactured elsewhere, so perhaps not so good quality?But I was wrong! This is a 100% genuine full-spec Bosch part manufactured in Germany. See the pictures of the packaging I have uploaded. The sensor comes complete with a full installation kit and has the proper connector already fitted. Some other sensors don't include this and you have to fit the connector yourself.It is now installed in my car, and it works perfectly. I wasn't sure if my sensor needed replacing but after replacing half a dozen other components in the vacuum system and still having the MIL light coming on, I thought it worth a try, especially at this amazing price.A couple of tips if you are thinking of buying one. Firstly, do NOT remove the protective cap from the sensor until you intend to install it. It is there to keep the special lubricant in place so you can remove it in the future. Secondly, you must remove the old sensor whilst the exhaust is hot otherwise you can't get it out. Be very careful, protect your arms and hands from burns from the exhaust and engine block. Thirdly you must use a special 22mm oxygen sensor socket spanner, they are about £10 - but its impossible to remove without one.It appears to be a recommendation to replace this (upstream) sensor every 100K miles. My car has only done about 65K but the sensor had been contaminated with a silicon sealer used to seal the rocker gasket. Oxygen sensors do NOT like silicon - mine worked but was slow response, reduced the engine power output and caused lumpy idling. Much better now.

You guys are a life savour ! I was on holiday 400 miles from Home when my EML light came on with error p0193 fuel pressure rail sensor ... got this delivered to a local Amazon locker by where I was staying , swapped the part in about 15 mins and the cars good as new ... Ford direct wanted £98!! Thankyou so muchCar - Focus st 2.5 ( 2007)

My Volvo S40 2.4i (2004) had a check engine warning light come up, at first it was intermittent but as the engine was running fine I left it alone. After a while the engine started stuttering & died, luckily I had an OBD2 Bluetooth adapter/reader that allowed me to connect to my android smart phone & scan for errors, which it did (PO129 Fuel Pressure Low Input)I Googled the fault & found that I needed a new Fuel Pressure Sensor, I shopped around & much to my surprise I found it here on Amazon & at a really good price. Combine that with Amazon's Prime Service I had it the next day, Chuffed!!If you look around (Google it!) I found some instructions on how to swap out the sensors in under 45 mins (I have a very basic knowledge of mechanics, I'm more of a techie!)Overall I'm very happy with the service provided & even happier to get the issue on my car sorted cheaply & easily!Keith.
