Hello everyone,

Decided to show off my Leon.
Bought it in 2022, car is manufactured at 2018, had nice package from factory - leather interior, full led lights, ACC, Line assistant, DSG, VR panel, MIB2 High, actually quite nice package for Style version. Ah it have 1.6 diesel engine with 85kw, for me it is enough as it is daily car, cruising to work and so (sunday car is Kodiaq).

And then... Browsing internet and forums, I can't sit still and retrofitting begins... :D

Will write about retrofits in backward order, and will post some older retrofits later.

So.. This time is about retrofitting memory seats.
As Kodiaq have memory seats, I was always wanted them also in seat as sometimes with this car drives also wife. So started to search, and found Ergo seats from Octavia 4 in mint condition, black leather and so, but missed this deal due somebody was bought it faster. Those seats had ventilation and so but ehh nothing this time.

I continued to search, it taked few months, I was looking for both front memory seats, but no luck. Then suddenly appeared memory seats from Kodiaq for sale, driver seat was with blown airbag, no leather, but the price was great and even control modules was under the seats (price for seats was like price only for control modules). So searched a bit in internet about to construction of seats itself, luckily I taked out seat from my Kodiaq to test fitment and it fitted nice, but not great (seat height is bit higher in minimal position) but it was like I need, so I bought them.

Going to pick up seats to another country also was like a small adventure with my 5 years old son, but this story is not about that...

So bringed seats home, after few days started to tear down new seats untill frame, and then teared Leon seats, and no wonder, Leon cushions was fit nicely to Kodiaq frames! :) Even connectors for wiring under seats fitted Leon<>Kodiaq. And Airbag from Leon too was fitted on Kodiaq frame, actually it was same looging, just different fitting holder which can be changed to needed one. I was happy enough, because in internet there is not much information for such a transformations... So done both seats, and then started wiring, It was not hard, made my own wiring combining Kodiaq and Leon wiring and it works great for me.

Putted everything together was no wonder, everything worked after correct codings and so, but only in Infotainment 5F there is appearance problems for "Easy Entery" function menu, probably somebody can help with this.

After a while started to dream about massage in drivers seat, started to search for module, and viola, found used module in Poland, for very VERY cheap price. Immediately contacted seller if he ships to my Country, and after on week I received module.
Was spent a few weeks for correct to find correct datasets for this as it appeared new moduly with no dataset on it... But at the end now I have memory seats with massage function, and everything works great.]

For now is enough, a bit long story for one retrofit, thanks for reading.

Here is some pictures from process.

Now will write about blind spot retrofit.
Some time collected information about this retrofit. Then started to collect correct parts.
When parts was arrived, reflashed modules on bench.

Then when all parts was received started to install them.
Wiring was from aliexpress, was need to redone it as wiring was for 5Q radars but I have 2Q...
Then changed mirrors from Arona.
As I seen only retrofits on pre face lift models where everything went well, then with FL models there is problem with radar mounts, there is no place for third screw, so I putted some hard automotive foam under mounts to avoid vibrations and so.

When I thought that hardest part is behind and all problems solved, it started even worse, it was not possible to fit rear bumper back..
So looked for places which not let me put the bumper back and found out that radar mount edges are those who shits everything up.
So decided to trim them down till radar. And done some hot glue over foam to avoid radar from vibrations even more.

Now bumper fitted like original with no problems.
After everything was assembled together and connected as expected, was done correct coding for everything.
After all it is working nice, was need to play with datasets and for now best dataset is from Passat B8, for others was some false alarms that somebody is in blind zone whilst there was nobody. Now its like already 3 months driving with this retrofit, no problems at all.

This post will be about Heated steering wheel retrofit from Leon 4.
At first bought the wheel from Leon 4 and then to find airbag it taken some time.
Control module under steering wheel (slip ring) was ordered from aliexpress, also new 16 pin connector.
Repined connectors as I didn't wanted any adapters to use.

First setup with aliexpress module was working for about like one month, then it stopped to heat steering wheel. And no alarms or messages, just not turning on heating for the wheel.

Started to looking for original vag module but no luck, and new one is a bit expensive. So decided to order module from tiguan (same as kodiaq). And yep, it is slightly different "shape", electrically it fits and car can do communication well , but fitment itself is different, so I got to order tiguan stalks (was very cheap).
Then also stalk mounts is a bit different so was need to cut something "here and there" to fit for one winter, as it was cold but wanted heating for the steering wheel to work. Now in the summer I hunting right module to fit back right stalks, just did not like that I know that there is something cutted and so on under the wteering wheel trims.

Here is some pictures from process again:
