EGR Cooler Problem

[snapdragon]

Just a quick update and thanks for all the help. It was the EGR vacuum solenoid 059906628B. It is one of the first things I replaced in 2017 and was GEPCO branded from Germany for 60 Euroshekels.

I remember that after replacing it the EML light went off on it's own after a couple of days which was a first and a really good sign but came on a few weeks later so it was back to the drawing board and buying more parts. If I had the vacuum tools and troubleshooting knowledge back then I probably would have diagnosed the part as faulty and returned it.

As I assumed that it did not fix the issue, I sold the old one on ebay as working. So sorry whoever go that.

I now have a genuine used part for £20 with a 2014 date stamp.

The morals of the story ares that replacing parts needs to be done in-hand with proper diagnosis if possible.

Cheap Chinese parts are sometimes garbage (remember the aliexpress vacuum solenoid for the EGR cooler failed too)
