01,406 Hdi fuel guage

Post by Peter.N. »

Hi again

My reliable 406 seems to be letting me down this week. Filled it up with fuel a week or so ago, the level had dropped to just above half full, a couple of days ago I noticed it was reading full again, so unless the diesel fairy has been round during the night, I think something must have gone wrong. The remaining mileage reading seems to have gone up as well so it seems sensor related but I have noticed today the the gauge is dropping slightly, reading between full and 3/4. Any suggestions?

Thanks

Peter.

Could well be the sender unit. It's part of the in-tank fuel pump, and they go wrong for a pastime. Either the unit develops a fault, or the plastic locating tab for the float arm breaks, allowing the arm to do whatever it likes.

The other possibility could be an electrical gremlin.

Try disconnecting the battery overnight. If that fails, there is a BSI reset procedure which may work.

A quick search on Google will reveal the procedure.

Then it probably is a wiring fault, and it probably will happen again, Pete ...
