Then after a couple of miles it shot up to full and after a few seconds back to empty. Does this sound like a gas guage sender problem?

The fuel sender and fuel pump are aparently one assembly. I had one replaced under warranty soon after I got the car, and the second (there are two pumps) a few years later (also under warranty. It seems this is a common problem with the ti's as well as the Z3's. If the fuel pump has not been replaced under warranty, this is most likely the solution. By the way, when the first one went bad, it showed 1/4 tank of fuel as I ran out and was siting on the side of the road.... The second time, it went totally empty (and the light came on) right after I finished filling it and drove onto the highway. So, it could fail both ways it seems... | | | 04-04-2003, 08:13 PM | #3 | Junior Member Join Date: Jun 2003 Location: Jouston, Tx, USA Posts: 4 | Since seeing the gas guage go to zero I have since realized the temperature guage and cruise control were also no longer working. The service manager at my local dealer suggest I check the instrument cluster fuses. I discovered fuse #46 was blown and when I replaced it everything started working again. So far it hasn't blown again so I will keep an eye on it.

Often us non-smokers use the ashtray as a coin holder, or for other little items that could fit in. The ashtray as it is designed to do can come out of the holder so that you can clean it but what we do not realize is that the smal metal items like coins someties go under the ashtray. There you also have the exposed wires of the cigrette lighter and if the metal product shorts the two connectors it does blow your fuses OUT. Typically the fuses effected are the gauges ones.

I replaced it and all is well so far. Another thing that a mechanic told me was that a faulty cell phone charger adapter can also trigger a series of blown fuse, so try to take the charger unit out of the cigrette lighter and check it. __________________ ***SOLD***The Ultimate Dying Machine!!!

Mine acted up for a few months an then fixed itsself. But I was going to pull the tank unit and before I did...It's no longer a problem. Incidentally, by the time I was down to 3/4 tank it read fine. __________________ [size=-2]95 Sport-Alpine White-5sp conversion, M3 clutch, 3.72 E30-LSD, Bilstein PSS-9s, 3"stainless-TriFlo, 17s from 330i staggared w/BFG KDWs, DASC K&N w/foglight intake, cross-drilled BavAuto rear rotors w/Pagids, 4-pot Brembos w/drilled 320mm front rotors, stainless lines, BimmerWorld RSMs. BavAuto front splitters.

Whenever I'd be driving and brake suddenly, the therm and gas gauges would shoot to zero, and move around every sharp turn or bump .... I took out the trunk panel that covers the speaker and brake wires (the plastic between the brake lights)... noticed the tape that surrounds the wires had loosened and the wire had an open spot that was exposed and could touch the body of the car whenever there were sudden stops or turns. Got some electrical tape and taped all the wires up ... then just to be sure it wasn't a part of the brake light touching the inside panel of the car, I put some tape around the lights and any metal I thought could possibly touch the body. Replaced the blown fuse, and for the past 4 days I haven't had a problem. I'd suggest everyone open that panel up and tape up all those wires, there's no doubt that over time the tape will loosen up and these wires will start moving around more than they should ... I don't know a lot of electrical, but I think taping everything up back there will prevent any future problems. | | | 09-06-2006, 02:00 PM | #9 | Junior Member Join Date: Sep 2006 Posts: 1 | need help Im having trouble finding out which fuse is wht in my ti? is there somewhere or a picture that i can find these fuse to fix the same problem u guys are having.

After driving for 50 or so miles, if I shut the car off, it reads correctly after restarting. If I don't shut the car off, however (i.e. long road trip) it stays on empty.

I pulled one from a 328 and soldered the wires on and the whole unit itself. Weird problems. BMW's love to start going haywire when it comes to fuel. __________________ Mmm.. | | | 09-06-2006, 09:54 PM | #13 | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 | Quote: Originally Posted by mason247 Im having trouble finding out which fuse is wht in my ti? is there somewhere or a picture that i can find these fuse to fix the same problem u guys are having. Thanks , Marcuz | Marcuz; When you lift the lid for the fuse box (driver's side near the firewall) there is a diagram on the underside of the lid for what fuse is which, like they do with boxes of chocolate. __________________ I scream, you scream, we all scream for ZOMBIES. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
