Cold start properties and error memory (3,6)

Hi,

Today I read out the V8 from which I posted a few weeks ago, and I had the following in the error memory (except the mandatory speed sensor wg. Standstill):

Control Module Part Number: 441 907 404
Component and/or Version: MOTOR PMC 1
Software Coding: 0261200183
Work Shop Code: 1267355684
4 Faults Found:
00515 - Camshaft Position (Hall) Sensor (G40)
03-00 - No signal
00525 - Oxygen sensor (G39)
02-00 - Signal Shorted to Ground
00523 - Intake Air Temp Sensor (G42)
01-10 - Signal Shorted to B+ - Intermittent

The reverberator is brand new and was replaced because the machine did not sprung at all (after exchange it ran again). Then I deleted the bug memory and drove around the block for a lap. What else could be found:

2 Faults Found:
00515 - Camshaft Position (Hall) Sensor (G40)
03-00 - No signal
00525 - Oxygen sensor (G39)
02-00 - Signal Shorted to Ground

The second problem is probably due to a problem with the cable by replacing the Lambda probe (which is also new), since the plug is broken. To the first problem: Where would you look for the cable break (after which the reverberator is new)? Is there a plug somewhere between the transmitter and the ECU? If so, where?

To the symptoms: At cold start the car pulsates, if you accelerate - if the machine goes over 60°C, pulsation is gone. At the stand he runs completely calmly (even in the cold start). The consumption is normal. The pulsation is returned regardless of the machine temperature over 140 km/h (plus acceleration). In between (if it is warm) nothing pulsates.

How/where/what would you start looking for/changing first? It can be pulsated below 60°C or less. over 140km/h only come from the intake air temperature sensor? Does the error indicate a defective sensor or actually a cable breakage? Dito is the problem with the Lambda yes the cable, not the mass, or (is short circuit on mass)?

Thank you for your help and greetings
