I’ve been thinking about the flat bottom mod for a while so thought I’d write a how to for anyone else that is interested.
The reasons I like it are:
- Vanity (Flat bottom steering wheels are cool)
- DSG paddles
- Fuel Economy (we’ll get to that later)
- It’s easier to turn a flat bottom and it fits past my fat legs!
Warning: if you don’t disconnect your battery then your airbag could go off when you disconnect the plug. Even worse than that, when you release the first airbag spring clip your horn will get stuck on and your neighbours will think you’re a bellend!
Some things to know:
- Not every VW flat bottom wheel will fit your van if you’re planning to reuse your original air bag. We’re looking for wheels with the 2 hooks that the airbag attaches to.
- If you buy a wheel which includes an airbag (from a Polo for instance) you need to make sure that it has the same button layout or it won’t work
I currently have a highline MFSW without ACC. I bought a second hand VW Golf Mk7/ Passat B8 wheel which had covered 10,000 KM with ACC and when I received it, it is a brand new wheel. I paid £105 and the part number is: 5G0419091. Some people use Golf R and Golf GTI/GTD wheels but I wanted the OEM look, personal preference.

There are plenty of these wheels on ebay in excellent condition and don’t be put off by the ones without an airbag or without the buttons/surround because in this case we re-use them from your original wheel.

Fuel Economy: My original Highline wheel weighs 600 Grams more than the flat bottom one, so the money that you save on fuel pays for the wheel!

I know that's sad but I noticed the difference in weight when I picked it up.
