    I read your post about fuel gauge readings... I found this in a quick search of the net and it makes sense.

    "Fuel gauge: The engine may not start or may stall because the tank is empty yet the gauge shows fuel remaining, or the fuel gauge will not show full after refilling due to sulfur corrosion of the fuel level sender and, if after treating with Fuel System Cleaner PLUS the problem remains, the sender may need to be replaced. (2004-06) "

    I recall some gasolines have had trouble with too much sulfur (or not the right additives to handle the sulfur) from a couple years back. That included a name brand in the Louisville area. I have a suggestion.

    At Pepboys or Advanced Auto or Meijers or Walmart they sell Techron Fuel System Cleaner additive by Chevron. I think there's even a rebate for all of the purchase price back on the 12 oz bottle that I saw in an ad within the last week. Maybe a company rebate rather than the chain store... Note this is Fuel System Cleaner. There's another version called Injector Cleaner, which I believe to be weaker.

    The bottles say it can help protect your fuel gauge from malfunctioning. I would use the 12 oz bottle as directed. Put in with tank almost empty at the gas pump. Put in up to 12 gallons or 20 gallons of fuel. Then drive without adding fuel until almost empty. It may clean the corrosion off the contacts that rub for the fuel gauge to give the reading on fuel level. You might use it a second time. But don't use it continuously. I use it one or two times a year in my leSabres. It always makes the engine seem better after a few miles when I put it in. I don't believe in additives but this one was recommended years ago by BMW and then others to clean injectors and deposits before gasolines additives were improved. It's the additive blends Chevron/Texaco put in their fuels.

    What you are describing is not my problem. My fuel gauge problems started from day one when I purchased the car new (Aug 2006). I have had several contacts with other Lucerne owners experiencing the same problem as I. This problem is occurring in the 2007 and 2008 models. As for LeSabres, I have owned two, a 1989 and a 2002 both purchased new and never had any problems with the fuel gauge -always giving me correct readings. As I stated before, I have been driving for over 50 years and never had any problems with fuel gauges on any car I have owned. This is a Buick screw up.

    Since I took delivery of my new Buick Lucerne CXL the gas gauge has never read properly. It either reads right or a quarter tank less than what is in the tank. GM has checked all the wiring, dropped the gas tank? and replaced the sending unit as well as the computer upgrades. Nothing they have done has fixed the problem. If anyone hears of a fix please advise. Thanks Bob
  • I had a gas gauge problem on my 1999 Cadillac w/Northstar engine... the Fuel Pressure Regulator was replaced & it resolved the issue..... I do not know if my 2007 Lucerne CXL has the same part as I not having an issue @ this time....Good luck....

    If you are not having a problem with your fuel gauge, you are fortunate. Owners of 2007 and 2008 Lucerne's are experienicing the same problem as me. Again, according to Buick, this is their design and may take up to ten miles of driving for the fuel gauge to correct itself. They are right as I have tested this several times.

    Not sure why yours work correctly and mine doesn't.

    Buick has a fix for the darkness of the instrument cluster, I had it done on my 2006 Lucerne. They completely replace the instrument cluster with a cluster that has bigger and brighter numbers. The cluster still does not light up during daytime but, the bigger cluster is definately easier to see. It takes about 1 hr to make the change.

    Hope this helps.

    I received a document ID #2074841 #PIC4799 concerning my fuel gauge problems with my 07 Buick Lucerne CXL from General Motors. This is a problem for 2006-2008 Buick Lucerne and Cadillac DTS models. Should anyone wish a copy of the service bulliten please let me know.

    I would like to get a copy of the TSB you cited in post 20 of 20. How can we arrange that? Thanks

    I would like a copy of the document you mention in post 20. Many thanks!
  • rjwelshrjwelsh Posts: 4
    I could mail a copy to you?? Bob

    I appreciate the offer, Bob, but can't think of a way to enable your suggestion unless one or both of us puts an email address, phone number or postal address in a post available to any casual reader. One option is to contact a dealer with the numbers you kindly provided and hope the dealer will make the info available. Perhaps the forum host has a thought?

    You can send each other info on your carspace page. At the top of the page is a header with black print "My Carspace." Send an email from the carspace page (email is on the right) to the other user with their address as user@carspace.com. You can decide how to communicate from there if that's not sufficient!

    Or you can join a junk email group like yahoo and then give that email in the comments area on your Forum Profile. Anyone else can see your profile by clicking on our user name on any post!

    Another method is scan the document, post it on photobucket.com (free account there) and then post here the link to the document there. Anyone reading here could click and read the document just like people post their car pictures for here on Edmunds.

    Or you can scan it and post in your pictures area on your MyCarspace.

    I missed pointing out if you have a good close focus digital camera you can take a picture in good light and post the picture in place of a scan using techniques suggested above.

    You can scan or take a photograph with a digital camera to get a digital picture of the papers. Then you can post them as an image or a link to the image in your post. One way is to upload the digital images to your carspace account into your photographs. Another is to upload to photobucket (free) or an equivalent hosting service that stores your digital images and lets you link to them.

    By posting a link in the post, someone reading your post later can go to that link and see them in your photobucket account (or carspace account),.

    A problem with carspace pictures is there is a graphic advertising carspace that's on the bottom corner.

    I use photobucket most of the time.
