Floor lamination issue
My TUV already had complete floor lamination when I bought it. It was very useful as I could literally wipe the entire car with a damp cloth.
I have a habit of taking off the floor mats and dusting it before and after every long drive. Last week I observed some water collection under the FR LH floor mat. Since this was above the lamination, I just wiped it dry and put back the mat. Few days later, I found water again in the same place. I wiped it off again but registered an alert in my mind. Next day when I took off the mat to dust it, I found tiny cockroaches under the mat. I started to panic and began investigation. When I pressed my thumb against the lamination, I found water oozing out of the otherwise waterproof lamination. I was now sure that something is seriously wrong with the FR LH floorboard.
I had read on team bhp that the RR windshield washer is on the RH side. So that’s not the issue. I began to worry that the floor has rusted, and water might be splashing to the underbody from the FRLH wheel.
I first peeled off the FRLH portion and to my horror the factory fitted carpet was soaking wet, with tiny cockroaches running around. I removed three of the OE carpet clips and went till the metal floor.
My worst nightmare almost came true. As I suspected, the floor has started to rust, but there was no hole in the floor. But the NVH silencer which is stuck to the OE carpet has begun to rot, which had attracted the cockroaches. Not surprising considering the silencer is made of very low-quality fabric.
My suspect: An over enthusiastic cleaner may have mistakenly sprayed water inside the car, or the FRLH window might have been open during the wash.( I remember my wife complaining that the FRLH seat was a little wet when I took delivery from the dealer). And the floor lamination is not completely waterproof. It does have small cut-outs for the seat legs and the scuff plates have small gaps through which water can seep in.
So, without any delay I began to peel off the entire lamination. This was a back breaking process as I had to remove all the seats, A & B pillar lower garnishes & all 4 scuff plates. At the end of 2 sweaty hours the lamination was out, and the day ended.
I pushed my car into the parking lot and slept (the driver seat was out)
Next day, using a dry & wet vacuum cleaner, I sucked out most of the water from the FRLH portion of the OE carpet and decided that never again will I install the lamination.
Meanwhile, the water had already spoiled the NVH silencer adhesive and I was able to take if off from the OE carpet and hang it to dry. With this the carpet became 80% dry and I assembled all the seats back and vacuumed the entire car and left it in the sun for around 4 hours without the floor mats off and windows slightly open. This finally ended my 3-day ordeal and now I had to think what to do with the lamination.
There was no way I was going to remove the seats and install it again. So, I cut the entire lamination in small pieces – 1 each for FR LH and RH, 1 each for Middle row LH & RH, 3 for under the middle row seats as it has three legs, 1 big piece for the luggage area. I had to rip almost all the Velcro strips which were stitched to the B-Surface of the lamination as it was impossible to position the carpet without it. The Velcro used to stick hard as soon as I kept the lamination on the OE carpet. I positioned the pieces as much as I could and shoved the ends into the garnishes wherever possible. And finally, the TUV was back to normal and I could sleep without having nightmares of the floor rusting way!!
Pics of the entire operation below: (Pardon the poor lighting as everything was done in the basement after dark)
The floor lamination (Coco color)
FRLH lamination peeled out with the seat intact. This is when i realized the disaster
The OE carpet peeled out. The blue layer is the silencer with the adhesive having undergone water damage. Notice the small specks of rust
FR LH seat out
Notice the velcros holding the lamination. Its super tight. The lamination pulled the OE carpet out of the center console (top left). I have to push it back in. Three clips had to be removed to remove the OE carpet. Very difficult not to break the clip. I broke two, luckily i had spares. Notice the scuff plate removed.
Driver seat out
Lamination peeled out till RR legs of FR seats
Mid row seats were the most tricky. Thanks to T6+ not having fold able backrest it refused to come out of the car. I had to rest it on the RR & FR legs alternately to peel off the lamination.
All done
The culprit in all its glory
The lamination cut into small pieces. Notice how i also had to cut lines through the holes to avoid removing the seats again.
