I started my Skoda for the first time in about 10 days yesterday, and encountered really bad rumbling from the engine.

The check engine light was lit. I have mangaed to get the following error codes from the car:

16645 Cyl.1 Injector Circuit Low Input/Short to ground

16648 Cyl.2 Injector Circuit Low Input/Short to ground

16651 Cyl.3 Injector Circuit Low Input/Short to ground

16654 Cyl.4 Injector Circuit Low Input/Short to ground

16684 Random/Multiple Cylinder Misfire Detected

16685 Cyl.1 Misfire Detected

16688 Cyl.4 Misfire Detected

17833 Tank Vent.Valve Short to Ground

17843 Sec.Air Inj.Sys.Pump Relay Circ. Short to ground

We have had some heavy rain during the last few days. Do you think something has got wet and shorted out? Any idea what I should check\change first?

Thanks in advance

Bump. Can anyone help with this?

Thanks
