Good evening,

 

Skoda Octavia Mk1, 1.6, petrol, engine code AVU, BFQ. After the water reaches 90, the ASR warning light appears on the board and the following error:

 

17924 - Intake Manifold Valve (N156)

P1516 35-00 Open Circuit.     

 

I changed the two vacuum pumps - 1J0 906 283 C and 037 906 283 C. Likewise, no result. I checked the wires. Everything ok Where else could I check? Thank you.

The ASR button is useless, it cannot be activated or deactivated. If I clear the error, the ASR button works.

The error appears when I drive around town, with frequent braking and starting. If I go a long way, it doesn't appear. When I get home from a long drive and turn back to park the car in the yard, it appears

Can someone tell me where this valve (intake manifold valve) N156 is on this car model?

Good evening,

Problem solved. The topic can be closed.
