Water leaks according to mileage or running time
Increasing mileage has an effect on the problem of leaks in a vehicle. Possible influencing factors are:
Servicing and maintenance of seals:
- No maintenance, lack of maintenance or incorrect maintenance
- Using an incorrect agent
Damaged seals:
- As a result of aging, wear or incorrect handling/assembly.
Heavy soiling of the vehicle:
- Heavy soiling of a vehicle can seriously impair the function of water drainage channels in particular, and also of
rubber seals.
Age-related factors:
- Environmental factors
- UV radiation
- Extreme climatic conditions
Corrosion can have a serious impact on bodywork, in particular as a result of:
- Lightly or heavily rusted seal carriers
- Rusted body seal welds
- Perforation corrosion
Water leaks after body repairs
If a vehicle develops a leak after body repairs, the following points must be taken into consideration in particular:
The correct seating of ancillary components and their seals must be checked.
The correct alignment of doors/tailgate and liftgate must be checked. The associated seals must not be damaged and
must be installed correctly.
Check that panel seams are correctly sealed.
The correct seating of rubber grommets must be checked.
Directly-glazed windows must have correct and complete bonding.
Water drainage system
If a vehicle develops water leaks, then areas into which water is routed or drained should be checked first.
Side windows
In the case of side windows, the same problems can arise as for a windscreen. The same corrective actions must therefore be
used.
Door seal
Diagnosis:
- Water ingress in the lower part of the interior door trim or in the rocker panel area.
Cause:
- The water shield fitted behind the interior door trim exists to drain off water that has entered the door via the
drainage holes, either downwards or outwards. If the water shield seal is damaged or has been fitted incorrectly,
then water can get into the passenger compartment.
- In addition to this, the drainage holes can become clogged with leaves, dirt or excess cavity protection agents.
Water gathers in the door and ingresses into the passenger compartment.
- Check water shield for damage or correct fitting.
- If the water shield needs to be re-bonded, then approved seam sealer should be used.
- Before the water shield is installed, the drainage holes must be checked for unhindered flow.
Door seals
Diagnosis:
- Ingress of water into the rocker panel area
Cause:
- Insufficient clamping load between seal and door.
Corrective action:
NOTE: When adjusting the clamping load, the profile alignment of the relevant components must always be taken
into consideration.
NOTE: Do not realign the flange too far in the direction of the door, as this can reduce the bearing surface of the
seal to the door.
- Check clamping load:
- The easiest way to check the clamping load of a seal to the respective bearing surface is by means of a paper
strip test. This consists of trapping strips of paper at various points between the door and the seal, and fully
closing the door. If it is possible to pull out the paper with no great resistance, then the clamping load is too
low.
- Adjust the clamping load:
- The clamping load is normally adjusted using the striker. When doing so, the edge alignment from the door to
the side panel, or from the front door to the rear door must be taken into account.
- Another setting method is to realign the panel flange for the seal mounting. The clamping load is increased by
moving the flange towards the door.
- Check the bearing surface:
- Apply chalk evenly to the surface of the seal. Evenly coat the bearing surface of the door with Vaseline.
- Close the door fully, the lock must engage. Open the door. The imprint of the chalk (bearing surface) can be
identified in the film of Vaseline.
- The bearing surface should be at least 5mm across at all points.
Other causes:
- The door seal must completely seal the door where it meets the bodywork.
- Water can ingress directly or indirectly into the interior of the vehicle if the seal is damaged at any point.
Corrective action:
- A damaged or worn door seal must always be renewed in full.
- When renewing the seal, the following must be taken into account:
- Always fit the seal first in the area of the narrow radii (corner points).
- Next, secure the seal to the flange evenly by tapping lightly with a rubber hammer. The installed seal must not
be kinked at any point.
NOTE: The prescribed length of a seal must not be shortened.
Other cause:
- The door seal is attached to the welded flange all the way round. If this welded flange is uneven or damaged at
any point (usually in areas with small radii) then this point could be subject to leaks.
- A stretched seal carrier can also cause a leak.
- In both cases, water gets into the vehicle interior under the seal carrier.
Corrective action:
- Align the deformed welded flange using a hammer and anvil block, prevent and, if necessary, repair any paint
damage.
Sliding roof/tilting roof
Diagnosis:
- Ingress of water at sliding roof aperture
Cause:
- The sliding roof/tilting roof is installed in a water trap. The water drains off via the water trap, water drain holes
and drain hoses. The drain hoses lead downwards on both sides via the A-pillar and B-pillar.
- The drain holes or drain hoses can become clogged with leaves, dirt, underbody protection and so on.
Corrective action:
NOTE: In the case of a sliding or tilting roof, the external rubber seal and the lock actuator or latch mechanism
must be checked first of all.
- Check the water trap for leaks.
- Check the drain hoses for leaks and for correct connection to the water trap.
- Check the drainage system for unhindered flow, and blow out with compressed air if necessary.
- Check the external seal and the correct adjustment of the sliding roof.
Liftgate
Diagnosis:
- Ingress of water into rear headlining area and luggage area.
Cause:
- The leak problems of the tailgate and liftgate correspond to those of the doors.
- In addition to this, the area to be sealed is much bigger. The routing holes for cables and hoses must also be
sealed.
- The rubber grommets for the routing holes must be checked for damage and correct seating (fully unhooked).
- The mounting points of the liftgate hinges may leak.
Corrective action:
- Check the rubber grommets and renew if necessary.
- Check the hinge mounting points, and re-seal with sealing compound if necessary.
Forced air extraction
Diagnosis:
- Ingress of water into side luggage compartment area
Cause:
- The forced air extraction for the vehicle interior is located in the quarter panel lower extension.
- The rubber flap of the forced air extraction must be able to move freely.
Corrective action:
- Remove the forced air extraction.
- Check the seal area between the bodywork and housing, as well as the rubber flap.
- Renew seal if necessary.
Rear window
Diagnosis:
- Ingress of water into the luggage compartment area
Cause:
- Rear window leaking.
- Check for leak in the same way as for leaking windscreen.
