Darn I thought I got lucky on a good running 99 SLK230 Kompressor (171K)

But after driving it for the 1st time today. Got these codes. Cleared them but they came right back.

P1420 - Secondary air injection valve/solenoid - defective
P0446 - Evaporative Emission System Vent Control Circuit
P0443 - Evaporative Emission System Purge Control Circuit
P1525 - ABV Vacuum Solenoid Circuit Fault
P1235 - Fuel pump control out range
P1236 - Fuel pump control out range

I'll check for vacuum leaks tomorrow. Any other suggestions please share.

Thanks

K40 board looks ok to me? Any other suggestions?


Might try and get a smoke test done and see where are the vacuum leaks are at.

there was a post that said it might look ok but reflow the solder anyway
don't add new solder, just reflow the stuff there

Check those top left pads, the 3 in a row. Look with as much magnification as you can find. A touch of good rosin core solder will re-flux what is there, put the heat on the pin so solder will flow to it.
Most of those codes seem unrelated though... But take a very close look while it is out. If possible take a picture of them close up and post it.
