PS: dont mind the sound it was before i installed the exhaust but with exhaust its the same problem

I got the engine errors: P1235, P062D

Sry for my english i hope you understand me :D

Thx for your help!:respekt:

I'd start by checking to make sure the connector going to the DI pump and the DI driver are seated and not damaged. Both of those codes indicate a possible short or open on the DI circuit.

Okay and where/how can i check that? I also forgot to say that i already changed the hpfp. I cleand the connectors while changing it.

Alos check the DI compiter on side of engine has all three mount bolts tight including the hard to get at on at bottom and all conectors on DI computer plugged in all the way

I dont put that on til now just plugged it in. I will try it directly!
