Hello everyone
I present to you the most demanding repair on a very sophisticated engine for me. My profession is electronics. I apologize for the poor translation with google translator. Maybe some sentences will be weird.
This is my Audi A4 2.0TDI Quattro 190HP year 2016 with AdBlue system.Code of motor is DETA. It has 200,000 kilometers, and on diagnostics began to warn: fault P2002 SCR Efficiency below threshold.DPF had 60g of ash from max 80g.
Be aware, however, that the cause of this error is a clogged EGR cooler that can be cleaned just like a DPF, although all service technicians will tell you that it is not possible. You can expect a bill over € 3,000 or $.
