Trying to pinpoint the cause of various DTC's any suggestions welcome . I suppose sensors showing intermittent need replacing . ABS fault remains despite new sensor and manual wire trace

I am a competent mechanic , have a factory shop manual and the car has no mods or after market parts. I assume I have one sensor sending bad info to the ECU which is causing the other fault codes .
I am thinking the EGT sensor for bank 1 is the likely culprit. The intermittent cooling fault for cylinder 1 is somewhat confusing as I dont believe each cylinder has a separate cooling system . The code could refer to bank one which could explain the EGT fault . I just dont know where that sensor would be and the engine temp reading is normal. The engine runs fine , this is to get it smogged .Understand this is an old Cadillac designed pushrod motor which Bentley added twin intercooled tubos and Bosch fuel injection to . Plus my model was not yet fully integrated into the AUDI diagnostic system not to mention the limited manual that the factory provides .

PS.the car has two batteries and that should not cause these faults

The scan I sent had all that the system could access , as I mentioned this model is not fully integrated and this system is not designed to handle my year model

Did you have the ignition on when you did the scan? - sometimes Vign reports 0V (as your scan does) even when the ignition is on - which it should always be when doing an Auto-Scan.

I had the ignition on of course . VGN does not speak the same language as some of my controllers.

Threads have been merged.


Then surely you have a battery charger. ;)

Is there some reason you are obsessed with the battery .. that is not the problem . it will be fixed in due course

When the battery voltage is as low as shown in your scan many of the controllers cannot operate correctly and show spurious faults - this has been seen many times on here.

So when we see battery voltage much lower than 12V the first suggestion is always to sort the battery voltage out, clear the fault codes (to get rid of the spurious ones) and post a new Auto-Scan with a 'proper' battery voltage.

BTW what type of VCDS cable are you using - HEX-what?

Hex-V2 As I mentioned the car has two batteries , the one showing low voltage was drained down in the shop doing tests. The faults showed up prior and I cleared them and they retuned all while the batteries were fully charged . That said it is easy enough to change the battery . I will also pull the EGT sensor and have a look , may be simply coked up .

I'm not with the battery itself; only its state-of-charge.
the one showing low voltage was drained down in the shop doing tests.
Pro-tip: Use a battery charger to prevent that while "doing tests".
