Audi p200200 code

[Danial]

I have a Audi a5 2017 2L diesel. The amber Engine light is on and I checked the code is p200200 particulate trap bank 1, efficiency below threshold. 
 

anyone know what the problem is and how much it will cost to repair

Hi Danial,

I have the same error currently with my 2016 A4 2.0 TDI.

I have had diagnostics done at an Audi dealership who said that it needs a new low-pressure exhaust gas recirculation (EGR) cooler, as it is blocked.

a common issue i believe and tricky to fix requiring 7.5 hours labour. I have been quoted £2500 to repair it at Audi.

 

Does anyone know if it is covered or have had this repaired under Audi Extended Warranty?

 

Thanks
