Works as soon as installed and very easy to install and at a good price.

Oil leak from old sensor. O ring with replacement Bosch sensor felt good quality. Oil leak solved. Engine runs smoothly.

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.

Fits mk2 focus st just make sure to put some rag over the alternator to stop any drips when removing the old sensor

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)

I recommend

Thread stripped with ease, and little to now force when fitting. Very poor quality

If you get an unusual fan type symbol popping up on your display, it could mean that the temperature sensor is no longer in spec. That's what happened to me, and this unit solved the problem.
