Hi everyone,

It's an Opel Astra J 1.7 CDTI 110 HP with the Denso SH7059 engine. I'm getting the following error codes:

P0400
P0403
P0404

Can someone please disable the EGR valve and these DTCs?

Now I'm getting error code P160d. This also needs to be cleared. Could you do that? The EGR thing seems to be working.
