My footwell is taking in water. Carpet soaked under mat. Before I start looking, anyone know where it might be coming from. Model 88 Disco.
Spent 4 years under cover, now it's under constant rain. It's a boat you would need in the west of Ireland at the moment!!!! |

I found this in the archive:
Discovery vehicles built prior to VINs TA166766 and TA502644 may experience water leakage through the HVAC air intake located in the plenum area under the wiper valence/plenum moulding. Water enters the plenum between the plenum moulding and lower windshield seal above the air intake and leaks onto the passengers side front floor.
Vehicles built after the above VINs have a taller air intake that corrects this condition. Refer to Figure 1 for comparison views of the two plenum styles. This repair is to be performed only on vehicles equipped with the early style plenum.
RESOLUTION:
PLENUM DIVERTER INSTALLATION
Upon evidence of water leakage through the HVAC system, verify the complaint by spraying water on the windshield and plenum moulding in the vicinity of the air intake. Check for water on the passengers front floorboard. If water intrusion is confirmed, perform the repair procedure.
PARTS INFORMATION:
LRNA020001U Intake Deflector Kit Qty 1
MXC3130PUB Plenum Clips Qty 2
LRNA10570 Sealant (Or equivalent)
AWR2947 Seal Strip Qty 1
NOTE: Header junctions are often damaged by water leaks through the air intake.
Refer to TIB 86/03/97/NAS for header junction repair instructions:^ LRNAHDGK - Green Header Kit

^ LRNAHDSK - Grey Header Kit
WARRANTY CLAIMS:
80.15.89127 Time 0.80 hr.
Install water deflector kit and seal plenum
COMP CODE: 9A5N
Normal warranty policy and procedures apply
Repair Procedure
1. Refer to the Workshop Manual Sections 80 and 84 and remove the wiper arms and plenum moulding.
2. Remove the two bolts that retain the upper rear of the HVAC air intake.
3. Clean the firewall area along the top edge of the intake and apply a bead of sealant (LRNA10570) to the body where the deflector will be positioned.
4. Install the deflector body from kit LRNA020001U across the top of the intake. (Figure 2)
5. Secure the deflector with the bolts removed in step 2 and torque to 8 Nm (72 lbf. in.). Ensure the deflector is properly sealed to the body.
6. Peel the adhesive strip from the back of the foam seal provided in the kit and install the seal along the top of the diverter. (Figure 2)
NOTE: Do not seal the windshield lower seal to the plenum mounding as described in TIB 76/01/95/US.
7. Refer to TIB 76/01/95/US (Water Ingress into the Passenger Footwell) and install deflector AWR2947 on the right side of the plenum moulding if not previously installed. (Figure 3)
8. Remove three foam filter blocks from the right hand side of the plenum housing and seal the three drain holes in the bottom outboard corner of each cavity using sealant. (Figure 4)
9. Install filter blocks and plenum moulding.
10. Assemble removed components.
11. Water test to verify effective repair.

It also could be coming from the sun roofs or the rubber seals around the windscreen.

Check to see that there is not a fatigue fracture under or around the strengthening
plate which is welded on the inside of the footwell.
You can see any fracture cracks from underneath the vehicle just behind the point where the body is bolted to the chassis.
If there is a crack, or a series of cracks as happenned in my 1994 300Tdi, the road spray will pour into the footwell.
