Hi All,

Getting the following codes when doing a full vag scan on version 3. The car is in the title.

00532 P1750 Supply Voltage (B+)
00561 Mixture Adjustment Control
16500 P0116 Engine Coolant Temperature Circuit - Range/Performance Problem

16518 P0134 O2 Sensor Circuit - No Activity Detected (Bank 1 Sensor 1)

16716 P0332 Knock Sensor #2 Circuit - Low Input (Bank 2)
17735 P1327 Cylinder #3 Knock Control Limit Attained
17736 P1328 Cylinder #4 Knock Control Limit Attained

Does any kind soul have any ideas what could be causing them? I know I need a new coolant sensor. My auto box is particularly jerkey, is this in any way connected to any of the codes?

Many thanks for any suggestions.

All of the faults could be the result of the engine coolant temp sensor. But, to really determine that, a full autoscan from a current copy of VCDS or VCDS-Lite would be preferred.

Thanks for the reply. I'll update to a recent version. I'm changing the coolant sensor over the weekend so fingers crossed
