ND-Photo.nl 's - Seat Leon ST Cupra 280

Changed the coolant expansion tank. After re-ordering a couple of times, I just went with the Nissens one. I thought it was a "G12" version and not a G13 with the silica bag. I removed the bag off course before fitting it.

Cap was also swapped out. Cheap item and its a mechanical item in the end (spring loaded cap)

The old colored one

Fresh items always look better

I will do a proper flush later, but added the G12 Evo from Kroon Oils

All done!

Added some felt strips to the subwoofer for some anti-rattle prevention. In the end I added a little more but forgot to shoot a new picture

With the subwoofer removed, I went ahead with insulating the boot. This made a big difference in sound deadening. There is already sound deadening material applied from the factory, but never hurts to add a little more.

Just by tapping the metal, you will hear what parts need the most attention.

Before:

After:

In the near future, I will order more and also apply it to the wheel wells and doors.

One of the first times when I needed to fill up. I was notified that the mileage could be a tad better. After this, I resetted adaptations and tried again

This was already heaps better than the mileage of the CLS55, where it averaged out on 1:6 Also the CLS55 has an 80 liter tank vs 50 liters on the Cupra

Have you played with the Individual mode settings yet, you can turn on coasting (cant recall the name on the screen) to allow the engine to drop to tickover when you are cruising on the motorway and are going down a hill

Went to the local Carglass for a "nano coating", which is essentially RainX but stays on much longer. I already tested this on the CLS55 and some other cars before that. Big adventages: less need to use the wiperblades and I almost dont need to scrape the window when it freezes.

Costs: 39 euro, and it stays on for at least the winter months which is a bargain for me

I discovered that recently, I was driving in Comfort until not too long ago. I put the engine behaviour in Comfort instead of Eco and tweaked some other settings, Individiual mode it is

But its not an eco car in my eyes, so I refuse to use it that way haha

My latest fill was already better than this one, will post that in a later stage

Decided to replace the cigarette lighter replacement with another one. The one I installed first needed to be switched on everytime, which I think is a nuissance. I replaced it with another one, which also looks better in my opinion

The dial in the Sport menu feels useless for me. It shows absolute pressure (so inc ambient pressure) and not boost pressure/vacuum. Also the placement of the screen is not inviting for me and feels unsafe when flooring it.

So I decided to add a boostgauge from "Greddy". This is probably not the real deal, but I simply don't care because the quality is that good.. I have no other words for it. The gauge reacts very fast and the builtin screen has a very high DPI and good response time. When starting up, it has a staging/needle sweep routine, awesome This unit works with a pressure sensor, instead of routing the vacuum hose all the way to the back of the gauge.

To easily tap boost pressure, I found this adapter which sits between the MAP sensor and intake manifold. Fitment also 100% and makes things easier.

I bought high quality reinforced silicone hose from FMIC.pro

MAP sensor off course

Sensor looks a bit dirty, I carefully cleaned it as good as possible, but it will be replaced anyway

The longer provided screw was a bit too long, so I used some washers

Enough room to route the reinforced silicone hose around everything

Luckily, our Seat/VW brothers made it very easy to route some cable/hose into the cabin. Right behind the brake pedal for the drivers seat (in the correct place, J/K for my UK brothers ) there is an unused bung. So punch through that, presto!

Work in progress

Right behind the soundproofing

There it is!

This is the bung, with partnr: 5Q0723753

After routing power (I tapped off the cigarette lighter fuse), it simply works! Screen has adjustable colors (also for day/night), the screen below is also able to show battery voltage etc.

Again, I am very happy with this modification

 

[nd-photo.nl]

The engine cover needs mild adjustment for the raised MAP sensor, nothing dramatic

 

[nd-photo.nl]

Changed the behaviour of the gas pedal to linear mode. Apparently some people notice difference, and some don't. For me it definitely feels more linear than before, which is more to my liking.

Driving Profile Switchover

Changed from Incremental to Direct

 

[nd-photo.nl]

After resetting adaptations I had some driving to do (around the holidays) and the mileage was lot better than last time. So, happy days!

Last time:

On the way there: 1:12.8 km's

On the way home, following the exact route back: 1:11.4 km's . Average speed was a bit higher, so I am not dissappointed!

Changed a setting called Starting Vibration Reduction from Strong to Normal

Was able to update the MIB2 unit using this thread: https://www.seatcupra.net/forums/th...h-asi-carplay-android-auto-map-update.469828/

After a little while I was treated with this screen

Replaced those rusted out discs which hold the heat shield with brand new ones (from Aliexpress). On some parts the material of the heat shield was rusted away that I had to use spacers.

I have a couple more to go on the rear

I wanted to replace the solenoid for the cutout valve as it was Tee-d from the brake booster hose. I am not a fan of splicing into important hoses like the brake booster hose, so that will need replacing.

I bought a standalone vacuum pump. I had a similar one in the Mercedes CLS55, which worked great. But after connecting everything, the pump is not working as it should. It keeps trying to create vacuum, even though the cutout valve is already open. Currently working things out with the supplier...

This is the solenoid valve & the amount of silicone vacuum hose that was removed

The standalone vacuum pump

The brake booster hose, partnr 5Q0612041AR. The hose is quite expensive at 180 euro , so I ordered a second hand one.

 

[nd-photo.nl]

The location for the pump, fits in perfectly in this location and no need for splicing wires. I can just use the unused 12v socket

Thats why I left a small patch open, so I could drill through the rubber grommet for the heavy duty silicone hose

 

[nd-photo.nl]

I opened up the pump and replaced some hoses to rule out some leaking, but no change...This is how it looks inside

 

[nd-photo.nl]

Had some golden heat reflective tape lying around, so used that on the intake hose because why not
