DIC message
I have 1400 miles on my new C6 and last night the DIC stated to service the fuel system. At the same time it said that the fuel gauge dropped to zero then it would reset itself. This did this several times then the check engine light came on. The car still ran fine but I returned home anyway. I called the dealer today for to get it in to have it checked and they stated they had several C6s do that. Has anyone experienced this problem and what could be wrong?

Yes, I had mine in at 1000 mi . for this . It is the fuel sending unit in the tank . Takes a day to repair . Bad gas clogs the unit . Use Chevron, 76 or similar high quality fuel only .

The problem with the C6 is different than that of the C5. I got this info at an other source.
-------------------------------------------
There are parts and it is a different issue. This is a copy of the message
that was sent to all Chevrolet dealers on 5-5-05.
This is a Service VME to all Chevrolet dealers relating to 1997 -2005
Corvettes with erratic fuel gauges,
For 1997 to early 2003 or pre-FFS fuel systems, sulfur contamination was
the primary cause of erratic gauges. The use of Techron fuel system
cleaner was very successful in removing the sulfur contamination, Again
this was for PRE FFS systems.
The primary cause for erratic gages in the Corvette fuel system (2003 FFS,
2004, and 2005) have not been due to additives or aggressive sulfur (which
is not considered an additive). These sender cards have been updated to
the latest noble metal content that meets the new corporate requirements.
When this was implemented in BG on 11/17/04, the ink on the sender card was
not produced to print. This can cause either sender circuit to go "open"
when that tank is full and set a DTC, which causes the gage to drop.
Properly produced parts were implemented in BG on 4/1/05.
To correct this condition a service kit has been released. For the left
side part
88967316 includes the sender and the o-Ring. A kit for the right side will
be available shortly. Dealers are reminded that replacing the complete
fuel module is not an acceptable repair when only the sender is required.
As soon as the right sender becomes available a VME and bulletin will be
issued.
---------- additional follow-on ---------------
The issue with 2005 cars is the printed ink (This is where the resistance
is) on the fuel sender card does not go far enough and when the left tank
is filled the high fuel level forces the contact on the card past the end
of the ink path. This basically causes an open in the circuit that the BCM
does not understand and it drives the gauge to E. The reason it is
predominately on the left side is that is the tank that stays full the
longest. Remember the fuel enters the left and transfers to the right
side. The fuel is drawn from the right side first so the left tank stays
full longer. Anytime the fuel sender is forced off the ink path the gauge
will loose contact.
As of last week there was stock in SPO for the left side and more was in
shipment, Dealers misunderstand the system and think they need to replace
both senders. They do not. The correction is to replace the sender card
only in the left tank

1200 miles, same problem. Dealer has ordered the part with no ETA at this time. Once the part is in only a one day fix I guess. May just be a coincidence, but when the lights (DIC, fuel needle pegs and amber engine light) come on, I have removed the gas cap and then screwed it back on usually once or twice and the lights go away.. It seemed to work everytime...doesn't fix the problem, but it does make those damn lights go away until it does get fixed.

The above statement is rather confusing. It says that 2003 to 2005 fuel sending units don't have a sulfer contamination problem but then later says that the newer (non-sulfer-related) units were implemented at BG on 11/17/04. Which is it? Was the new design implemented in 2003 or 11/17/04?

New Parts
I had the same problem, dealer replaced both sending units (two tanks)
Now the good news GM doesn't really want to share. As of late may GM is sending a brand new updated version that of the sending units that are going into the new C6's being made. No more problem, they don't want us to know about it for fear problem or not we will want them replaced to prevent the problem from occuring. I've already got my service guy with two so I can replace mine with the new ones even though presently I'm not having issues. So go in and make a stink about it and try to get them replaced.
