which is exactly same as this post

I will replace the pressure convertor (11747796634) later, then I reckon the noise will be fixed.
Does the pressure convertor affect the fuel consumption?
What tools do I need to scan a code? |
Hi david2047,
Sorry, don't have insight into the pressure convertor and the noise you are experiencing.
Before you begin to tinker with the EGR valve and/or cooler, I would invest in a scanner (if you don't already have one). I personally use Foxwell NT530 and it has been good so far. This way you can check for any codes to diagnose the actual issue. For all you know the EGR could be perfectly fine and the problem might be somewhere else.
A lot of folks also use ISTA software to diagnose and run specific tests.
