Why does the OEM undertray for my Cupra 290 the small one?

[GrooveChampion]

My 2016 290 is supposed to have the small undertray that doesnt cover the oil pans, at least according to the parts catalogue(I searched with a VIN number)

Why is it that these cars come with the oil pans unprotected? And some have the full size undertray?

I bought a full undertray for my 2015 280 ST, bought an aftermarket unit with OE bolts (the 3x bolts in the back of the undertray)

3x Bolts WHT000729A

I bought these bolts a month ago from AliExpress lol

Whats the part number for the undertray?

Thanks bro!

I would imagine it's to aid airflow and cooling through the engine bay. It's not to protect the sump from damage.

To be honest, from what I've seen, if something hits the underside of the engine bay hard enough it tends to break straight through the undertray and smash the sump.

If you want extended protection for the oil sump you can use the undertray from Golf Alltrack, take a look at the thread below.

Personally I replaced the plastic one with ally sump (only because I wanted a baffled one)

To be honest my main worry aint the sump cos if I hit something hard enough I can wave goodbye to it

My main worry is how precariously the computer for the haldex diff is jutting out, I am scared it will get hit by road debris

Then you can do the replacement of the undertray that " nd-photo" have done.
I have the "big" thin standard undertray on my Cupra. My former Golf R mk7 had the small one.

Together with another car enthusiast with his Fiesta ST That red reflector strip you have is very nice, like the octavia vrs. Wonder if there is one for the facelift?
