2007 335i code 29f2
so like title says i got this code the other day when i was racing a bike in 4th gear i WOT and at about 5,000 rpm boom like if i hit a wall then got the half engine light took it to a shop and they checked my pumps and said all was good but that my low pressure fuel system sensor seems to be a little glitchey does anyone have a DIY on changing the low pressure fuel sensor and the part # would be awesome to i looked online but no luck finding a DIY i would like to avoid paying labor at the shop if its a easy enough DIY.

It depends on what you consider easy... You do have to take off your intake manifold ect.. to get to it. Its directly under the intake manifold or almost directly under it so I know that has to come off. When I did my walnut shell blasting, Sammy told me to go ahead and get the LPFP sensor to just save the headache of taking off the intake manifold twice since you have to buy new gaskets everytime you take it off and put it back on regardless of how old they are.

I cleaned my valves the same time I changed the sensor. I used all the old gaskets and my car runs fine. |

Don't need to remove the intake manifold. Just have to remove the intake and charge pipe (edit: and throttle body). Sensor is about $100 and install takes 30 minutes. There's a good write up on here, do a search, just did this myself last week.
