I have a 2005 VW Touareg and am getting engine fault codes PO300 through 306, does anyone know if it is plugs and wires, crank or cam sensor. Please help!

"i know the engin bay had a wash" says it all.

Crank shaft sensor.

check that the cam shaft is turning ( broken timing belt/chain will not allow position sensors to give spark). Check that the immobiliser is operational. have the fault codes read

code p3081 refers to engine temperature too low===causes--allow engine to warm up---cooling system fault
I would check for a thermostat stuck open

code p0322 refers to crank shaft position (CKP) sensor/engine speed (RPM) sensor--no signal===causes--wiring---CKP/RPM sensor---ECM

Have you checked the wiring that goes to both the Crank and Cam sensors? Most of the time the wires are close to a heat source (ie: exhaust manifold) and the plastic covering starts to melt causing the cooper on wires to make contact and thus making engine stop, you will have to take off the protective covering as well as tape around the wires and inspect each and every one. Had same problem with Dodge caravan, it turns out the Crank Sensor plug wires were melted together. Good Luck.

The light is telling you that there is a problem in the engine management system. Have the fault codes read and fix the faulty sensor/servo

i have seen many problems over 70k on us models misfire problems trans problems and tire pressure monitoring systems as i said us models

TRY THE MASSIVE AIRFLOW IF IT THAT IT WILL NOT CRANK AT ALL

P1381 Cam Timing Advance is excessive if it were that your check engine light would be on it would be throwing code were gonna test what hes saying

The 2 sensors are located at back-top of the engine, you should check the wiring first before you change the 2 sensors
