Hey guys,

I am going to decat my Touran 1,9TDI BKC.

My question is, are there any sensors that i will need closed off in the mapping to avoid enigne error logo in my cluster?

If I remember correctly it didn't need to disable anything.

N75- control solenoid valve of vacuum wastegate valve

You need to make N75 map a bit more conservative, otherwise you can experience some boost spikes.

As a complete novice, i dont understand that?

your boost makes more pressure without cat.
you have to adjust the n75 valve
