Hi there my DPF regen is every 50 miles, and when connected to VCDS it's says 85% full, car is at 180k miles, I've got DPF part number which is 04l131669JX and not any luck with getting one used as i can't find any, Skoda wants nearly 2K for new one, does anyone know if dpf with different letters at the end of part number matters at all ? As there is many with same part number but letters are different at the end. Thank you 

You can get oe replacement dpf. However it might prove a lot cheaper to get it cleaned out whilst fitted to the car.

These can be cleaned, send me a pm and i will let you have the details of the company we use to clean dpf's.

Skodavia messaged you.
