This Service Information bulletin supersedes S.I. 13 01 93 (3734) dated December 1993, which should be removed from your S.I. binder and discarded.
SUBJECT:
Feed Fuel Hose Recall Campaign No. 94V-066
MODELS:
E34 with M20, M50 Engines
Situation:
The potential condition involves feed fuel hoses that could, in some cases, harden and "set" over time due to engine compartment temperatures. If this "setting" occurs, it is possible that seepage between the hose and fitting could result because the clamp cannot provide sufficient sealing force to compensate for the hardening of the hose.
This "setting/hardening" effect of the hose tends to occur when there is no fuel flow and in conjunction with high.engine compartment temperatures - i.e., with engine off after running (e.g. overnight). Because fuel flow causes the hose to soften and expand, thereby sealing the hose/fitting connection, the seepage tends to occur only at and immediately after engine start-up.
Vehicles Affected:
This Recall Campaign involves E34 vehicles with M20 and M50 engines which were produced from 6/88-6/89 (M20) and 9/90-8/91 (IV,50).
In order to determine if a specific vehicle is affected by this Recall Campaign, it will be necessary to utilize the "Service Menu" of the DCS (Dealer Communications System). Proceed to "Inquires;" "Vehicle History" and enter the Chassis Number (last seven characters) of the vehicle in question. Based on the response of the system, either proceed with the iinstallation or take no further action.
Note:
If a customer presents the customer notification letter (for that chassis number) it is not necessary to inquire on DCS. Perform the required repair, unless the fuel feed hose update as descibed in an earlier version of this bulletin had been performed and a label with code number 89 stamped out is found on the B-pillar of that vehicle.
The Chassis Numbers listed are only for informational purposes and are not to be considered as the only deciding factor. The affected vehicles are limited to vehicles within these ranges, but not all of these vehicles are affected by the Recall Campaign. The final decision factor is the DCS inquiry.
Correction:
In order to update the affected E34 vehicles, all feed fuel hoses (1) located in the engine compartment and fuel hose clamps (2) must be replaced with the new style components included in the parts kit (see illustrations).
The new fuel hose included in the parts kit can be identified by the blue wiring on the black rubber background and should only be installed in conjunction with the new style clamps.
The new style fuel hose clamp can be identified by the plastic shear-off hex nut head (5 mm hex) and drive sleeve (see illustration - items (1) and (2) and, with the drive sleeve removed, by the slanted screw driver slot (item (3)) used only for loosening the clamp.
When the clamp is installed it should be tightened until the 5 mm shear-off hex shears off, thus assuring the proper torque. When removing the new style clamp it may be necessary to remove the plastic drive sleeve (item number 2) with a pair of pliers first.
Important Notes:
- The new style hose clamp is a "one time" clamp, i.e. whenever removal becomes necessary it cannot be reused and must be replaced.
- Whenever a fuel hose is removed from a fuel line/component in the engine compartment the hose and clamps must be replaced with the optimized fuel hose and new style clamps.

Recall Campaign Label Instructions:
This Recall Campaign has been assigned code number 89. After the vehicle has been checked, and corrected if necessary, obtain a label (SD 92-008) and:
a) emboss your BMW dealer warranty number in the middle of the label (1);
b) punch out code number 89 printed on the label (2); and,
c) bend the label to crease an edge and remove the backing paper. Then affix the label to the "B" pillar as shown:
If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the new label next to the old one. Do not affix one label on top of another one because a number from an underlying label could appear in the punched-out hole of the new label.
Warranty Information:
Reimbursement for this Recall Campaign, will be provided through Campaign Entry.
The notification letter will be sent to all customers with affected vehicles.

RECALL CAMPAIGN NO. 94V-066
Dear BMW Owner:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
BMW has determined that a defect which relates to motor vehicle safety exists in certain 1989-1993 Model Year BMW automobiles. Our records indicate that you are the owner of a potentially affected vehicle.
This notice supersedes our previous owner notification of the Service Action regarding the feed fuel hoses.
DESCRIPTION OF DEFECT
Your car is equipped with a feed fuel hose that could harden and "set" over time due to engine compartment temperatures. If this "setting" occurs, seepage between the hose and fitting could result.
The seepage tends to occur only at and/or immediately after engine start up and is associated with a conspicuous fuel odor.
DESCRIPTION OF REPAIR
The repair will consist of replacing the feed fuel hose(s) and associated clamps with a new design.
This repair will require approximately one to two hours and will be performed free of charge by your Authorized BMW Dealer. Additional time may be required depending on the Dealer's scheduling and processing.
PRECAUTIONS
1. CONTACT YOUR AUTHORIZED BMW DEALER IMMEDIATELY TO HAVE THE NECESSARY REPAIR PERFORMED AS SOON AS POSSIBLE.
2. An indication of the potential seepage from the feed fuel hose is the noticeable odor. If you encounter such an odor, immediately arrange with your BMW dealer to have the situation rectified. Prolonged neglect of the situation could escalate into a fuel leakage hazard.
OTHER INFORMATION
If you are no longer the owner of this vehicle, we would appreciate your furnishing us with the name and address of the new owner, using the enclosed return postage-paid card.
Should you have any questions about this campaign, please contact your Authorized BMW Dealer.
We appreciate your confidence in our product, and we wish to do everything we can to retain your confidence. Should you need additional assistance, you may contact BMW Customer Relations at 1-800-831-1117.
