Q: My mechanic added "necessary work" to the fuel pump replacement job. on 1998 BMW M3

My mechanic told me that the fuel pump cannot be sold without some sort of sensor, but that there are two of these on each side of the tank in order to maintain proper fuel readings on the dash board.

He explained that the other sensor MUST be replaced as part of the job, in order to ensure I get accurate fuel readings. This added $400 to the cost of the job, bringing the total to $1000.

Does this sound right to you?

only if you were having a concern with your fuel gauge.alot of times us technicians will try to cover our rear ends when we have a bad experience after a repair and something else fails,well it makes us look bad and our boss gets upset and yadayadayada,so we will will sell anything related to the part in question.So,if you are not having a concern with your gauge,then leave well enough alone and just do the pump!good luck!
Yea that was my impression, but he told me that the decision was based on BMW's specifications, as if he's legally obligated to replace both.

I'm sure I could have stood my ground and saved a few hundred. It's much easier to just find another mechanic though. :)

The level sensor can sometimes get tweaked when replacing the pump so he probably was just trying to cover the possibility of a come back. He was not legally obligated to replace them though.
