During my search for another rear differential I have found some cheap refurbished ones from China.

Do any of you here have experience with them?

The dif was manufactured by two manufacturers: Lindemann and Magna Powertrain. Magna manufactured at two locations in China and Austria. So it should have been properly made.

Thanks Cairus.
So I can rule out these chinese diif are not cheap copies and buy with confidence?

This unit was manufactured in Austria. If necessary, I can have the serial number checked.

I greatly appreciate you taking the time to help me.

VIN: TMBLJ9NE1G0136683

The original OEM should be 0CQ525010H, superseeded by 0CQ525010S.

The seller below also claims this drive 0CQ525010T will fit my car.

Rear differential Haldex 0CQ525010T VOLKSWAGEN SKODA AUDI SEAT CUPRA AWD 4X4 OE | eBay

This is a brand new original drive, if it fits I buy it instead of choosing remanufactured one.

M365 Co-Pilot tells me that the gear ratio maybe different though !
0CQ525010H / 0CQ525010S: 2.48
0CQ525010T: 2.24
If true, would it matter?

yes that would be important, because of the Abs

Would it be possible for you to check it for me using my VIN#?
