Campaign ID: TC-HX11-26-012
Vehicle: smart #1
Model series: HX11
Model years: 2022–
Powertrain: Battery Electric Vehicle (BEV)
Campaign type: Technical Service Campaign
Severity: Blue – Low
Status: Active
Estimated repair time: 0.2–0.4 hours

Campaign Overview

A technical campaign has been introduced for selected smart #1 vehicles to inspect the sealing element around the vehicle's charging port.

On certain vehicles, the charging-port seal may not be positioned optimally. Under unfavorable weather conditions or after washing the vehicle, small amounts of moisture may collect around the outer area of the charging-port housing.

The high-voltage charging components themselves are protected against moisture. The condition described by this campaign does not affect the safe operation of the vehicle or the high-voltage battery.

The charging-port seal will be inspected during the vehicle's next regular workshop visit and repositioned or replaced if necessary.

Customer Complaint / Possible Symptoms

In most cases, customers will not notice any symptoms.

Possible indications may include:

• Small amounts of moisture around the charging-port housing
• Water droplets visible after washing the vehicle
• Moisture around the outer edge of the charging flap
• Charging-port flap may occasionally feel slightly more difficult to close
• No customer complaint; condition identified during a regular inspection

Normal charging functionality is generally not affected.

Vehicles Affected

This campaign applies to selected:

smart #1

Depending on market and production configuration, affected vehicles may include different smart #1 equipment variants.

Production period: from 2022

Campaign applicability must always be confirmed using the Vehicle Identification Number (VIN).

Not every smart #1 is affected.

Cause

Due to manufacturing tolerances, the sealing element surrounding the charging-port housing may not be positioned with the intended uniform contact pressure.

Under certain environmental conditions, this can allow small amounts of moisture to collect in the outer area of the charging-port housing.

The electrical charging connections and high-voltage components remain protected by their dedicated sealing systems.

Customer Action

No additional workshop visit is required.

The customer may continue to drive and charge the vehicle as normal.

The technical campaign will be carried out during the next regular workshop visit, provided the campaign remains open for the vehicle's VIN.

If the customer experiences a charging malfunction, receives a charging-related warning message, or notices damage to the charging connector, they should contact an authorized service partner independently of this campaign.

Workshop Procedure

1. Verify Vehicle Eligibility

Check the VIN in the campaign or warranty system.

Proceed only if campaign TC-HX11-26-012 is shown as open for the vehicle.

2. Inspect Charging-Port Area

Open the charging flap and visually inspect the charging-port housing and surrounding sealing element.

Check:

• Correct positioning of the seal
• Uniform contact of the sealing element
• Deformation
• Cracks or other visible damage
• Evidence of moisture accumulation
• Condition of the charging-port housing
• Correct operation of the charging flap

3. Evaluate the Condition

Seal correctly positioned and undamaged

If no abnormalities are identified:

1. Verify correct positioning of the seal.
2. Clean the surrounding area if required.
3. Verify correct operation of the charging flap.
4. Document the technical campaign as completed.

Seal incorrectly positioned

If the seal is undamaged but incorrectly positioned:

1. Carefully release the affected section of the seal.
2. Clean the contact surface.
3. Reposition the seal according to the repair instructions.
4. Verify uniform fitment.
5. Inspect the area for correct sealing.

Seal damaged or permanently deformed

If the seal shows cracks, permanent deformation, or other damage:

1. Remove the affected sealing element.
2. Install the revised sealing element.
3. Verify correct positioning.
4. Inspect the charging-port area.
5. Verify correct operation of the charging flap.

Charging Function Check

After completing the campaign:

1. Check the charging port for visible contamination or moisture.
2. Verify that the charging connector can be inserted correctly.
3. Connect approved charging equipment.
4. Confirm that the vehicle initiates the charging process normally.
5. Check the vehicle display for charging-related warning messages.
6. Disconnect the charging equipment according to the normal procedure.
7. Verify correct operation of the charging flap.

No work on the high-voltage battery is required as part of this campaign.

Required Parts

Always verify the latest part number in the electronic parts catalog before ordering.

Required Tools

No campaign-specific special tools are required.

Depending on the work performed, the following may be required:

• Standard workshop equipment
• Inspection lamp
• Cleaning materials
• Approved EV charging equipment

Completion Criteria

The technical campaign can be marked as completed when:

• Vehicle eligibility has been confirmed using the VIN.
• The charging-port seal has been inspected.
• The seal has been repositioned or replaced if required.
• The charging-port area has been checked.
• Normal charging functionality has been verified.
• Completion has been documented in the campaign system.

Warranty / Campaign Claim

Submit the completed work under campaign TC-HX11-26-012 using the applicable campaign operation code.

Replacement of the sealing element should only be claimed if replacement is required according to the campaign inspection criteria.

Important Notes

This technical campaign has a BLUE severity level.

The customer does not need to arrange a separate workshop appointment. The vehicle can continue to be driven and charged normally, and the campaign can be completed during the next regular workshop visit.

The campaign is VIN-specific. Not every smart #1 is affected.
