Fault code question for 2002 996

[Vman]

The following fault codes show up on my 996 after I flashed it with a new engine program and can't be cleared (clear them and they come right back). They were not present with the old program. Nothing else has changed in the car. Any thoughts?

Motronic 7.8 Current

P0413 Porsche fault code 85 - Driver elec. switch-over valve Secondary air

P0418 Porsche fault code 84 - Secondary-air pump

P1674 Porsche fault code 497 - Final stage engine compartment purge fan

Thanks,

VMAN

P0413 Electric change-over valve - open circuit

Possible fault cause:

- Wiring harness

- Electric change-over valve

- DME control module faulty

P0418 Secondary air injection pump - open circuit

Possible fault cause:

- Wiring harness

- Relay faulty

- DME control module faulty

P1674 Engine compartment purge fan output stage - open circuit

Possible fault cause:

- Open circuit

- Relay faulty

- DME control module faulty

Do you do an adaption for the DME after programming?

Switch on the ignition

- Wait one minute. Do not press the accelerator

- Switch off the ignition for at least 10 seconds

- Read out the fault memory

Check the fuses and the relays - otherwise you may have smoked the DME.
