Does the Leon still have "films" in the doors?

Hi,

Does the Leon MJ 2001 still have the plastic films in the doors that were prone to leaking in the G1 and G2 models?

He always has a puddle of water on the sill after it rains, even though the door drains are supposed to direct the water outwards.

Speculation mode: The Golf 4 has a device carrier made from a single pressed part. Since the cars are quite similar, I suspect the Leon will be the same.

Thank you.

Does this device carrier have a seal that creates a tight fit against the door?
So, what was the function of the plastic covers in the older Volkswagen Golf models?

Because then, the same defect could potentially allow water to reach the wrong places.

Yes, that part seals against the door with a gasket. I can hardly imagine that it will leak.

On a Golf, removing the door panel in warm weather (due to the plastic parts) can be done in 5 minutes. You need to loosen two screws, one towards the A-pillar and the other towards the B-pillar. Then, carefully pry the panel away from the bottom, starting near the door handle. Remove the screw, and then carefully detach the panel, which is held in place by VW's typical plastic clips. So far, I haven't broken any, but always be mindful of the sun! Then, simply detach the train from the track using the track release tool, disconnect the plugs, and you'll be at the platform.

If it's like it is on the A3, it's even simpler. You just need to remove the screw under the "door handle," and I think I remember there being two small Phillips-head screws on the trim as well, and then the whole part can be simply pulled upwards. It's a bit better designed. Then, instead of just the device carrier being in front of you, the entire window frame and device carrier form a single unit. So, if the Leon has a visible transition between the door body and the window frame, it's likely the same system as in an Audi. If the door looks like a 4-series from the outside, you'll probably have the mounting tabs.


But let's ask a completely different question. Where is the water located? If it's located at the bottom of the rocker panel and in front of the seal to the interior, don't worry, I always see that after washing the car... it's coming from underneath/outside.

It's probably a fairly common problem with the Leon...

Hello.

[Quote from Seatforum:]

Please list the most common options.

1. Incorrectly installed cabin air filter (moisture detected only behind the glove compartment).
2.) Leaky inner panels in the doors (initially sealed with quickly absorbent tape).
3.) Leaky welds (often in the area of the front fenders or sills).
4.) 'Too thick' exterior door seals that allow water to pool on the threshold, and in heavy rain, this water can then seep over the threshold and into the interior.

I also have this problem; in my case, it's point 4) .

'Just taking medication hasn't really worked for me. Could you tell me what it is for you and how you got rid of it when it went away?' In the winter, this is really annoying because, on the one hand, the inside of the car freezes, and on the other hand, the water in the seal can turn to ice, making it impossible to open the door.

Best regards, Jochen.

So, the rubber seals at the bottom of the doors are quite dirty.
They don't look very dense.
Furthermore, the water would then need to be at a lower level on the sill.

I strongly suspect that it's the drives.

I can only take a look when I'm back at Loewen .

I'm currently wondering if so much water could accumulate in the doors that the water level would reach the plate if the seal is holding too tightly.

In my case, the entire sill is full of water, but the seal on the body side is dry in the upper area. In the first left-hand curve, it then happens due to the covering in the door.

Perhaps it's actually both, meaning a lack of proper flow and a leaky seal.
I hadn't taken the door apart yet, either.
After I cut the holes in the gasket, I initially thought it would be better, but now the effect is lost again.

Best regards, Jochen.

I received a PowerPoint presentation in the Leon forum that roughly describes how to improve the workflow and how to reseal the device holders.

Okay, bitte gib mir den deutschen Text, den du übersetzt haben möchtest.

Hello Martin,

Yesterday, after I washed it, I took a closer look at my door.
Water is also seeping out from between the trim and the actual door. Therefore, my drive will also be leaking.

Having read about the difficulties you encountered when removing the panels, and wanting to avoid the same problems, I'm wondering if it would be sufficient to simply remove the interior trim and loosen the panel slightly without completely removing it.
Simply seal the gap with silicone or a similar product.

Does this make sense, given what you've seen? How high would you lift the plate from the side? It probably won't leak around the edges.

Best regards, Jochen.

Hey Jochen,

Here's a testimonial from my friend, whose Leon we repaired.
The effort and the broken window lifter were definitely worth it. She would do it again in a heartbeat.
You only really notice the actual leaks once you've removed the panel. Also, it will certainly be difficult to apply any material (like silicone) and press the panel flat against the door around its nearly one-meter circumference. The question remains as to what the silicone will do to the old sealant and also to the metal of the door.

Our approach was also the official approach of Seat, and we considered it to be the most sensible option. What if your solution doesn't work, and you have to remove not only the old sealant (whatever was left), but also the silicone itself?

Following the motto: If you're going to do something, do it properly.

Sure, here's the translation:

"Additional:"
So far, we have only replaced the sealing strip on the front doors and have not yet cut the door rubbers. And the water stays (still?) outside.

The problem you're mentioning is a known issue with the Leon, and as a result, Seat offered a special warranty program for new door seals, etc.

As you wrote, the improvements, including those related to the door seals and the water problem, were implemented with the model year change from MJ 01 to MJ 02. After that, the issue of water ingress through the door seals was resolved.

In the Leon forum, back in 2003, we already assumed that the problem had been fixed at the authorized workshops for all vehicles from model years 2000 and 2001 - but apparently, there are still some people who are only noticing it now.

Hello,
My Leon is a model from 2002, and I bought it used about a year ago.
The vehicle has a complete service history, as documented in the service booklet, from a Seat dealership. (At least until it arrived at our workshop ).
Seat didn't do anything here.

The problem only became noticeable during the first winter, as the passenger door would occasionally freeze shut, and the passenger footwell was wet.
It wasn't until I started a more intensive search in the spring and summer that I tried all the 'simple' methods to solve the problem.

A colleague has a 2004 FR Loen. He's also not sure if his doors are properly sealed. He definitely already has Martin's PP.

Therefore, the problem is probably still not resolved, or the seals are aging, and the problem recurs .

Best regards, Jochen.

The problem your friend is having with water getting into the car likely stems from the interior filter being replaced carelessly by the workshop. If it's not installed properly, water can leak in through it. However, water ingress through the doors shouldn't be an issue for cars manufactured from the mentioned model year onwards.

*brought up again*

@Martin,

After having some water leaks in my Leon for the past few days, I finally took the time this weekend to seal the doors. Let's see if it's you now .

What I noticed, however:
Apparently, my previous owner had already had some work done on the doors, as there were clear signs of it.
However, the sealing cord was very crumbly and water-permeable.
Now the question arises, as hinted at earlier, whether these double-strand ropes are durable.
At least, a Seat workshop suggested using body sealant instead of the sealing cord.
Therefore, I followed that instruction.
Could it be that the sealant has been applied for the second time on your girlfriend's Seat as well?
develeye was confident that all the affected Leon vehicles had been properly sealed as part of the goodwill campaign.

I hope I'm wrong, and that you won't have to buy new electric windows again in 2 or 3 years.

Best regards, Jochen.

Hi.

So, "our" Leon was definitely NOT given a courtesy discount.
It was the obviously factory-installed, foamy, gray substance in the grooves of the engine mount.

It's also very dense in the front. It's coming up in the spring.

The sealing cord is perfect for these sealing applications. I used it years ago to attach the films to my 86c Polo. Also, the cord is so thick that you have to press the brackets firmly against the door before you can screw in the 10 screws. That means that, in its assembled state, the water has to overcome a significant amount of string.
