Hi, just got myself VAG-COM, very pleased with it! Hope you can throw some light on these codes please.
I checked why the engine light was on my sisters polo 9N.
16804 - Catalyst System; Bank 1: Efficiency Below Threshold
P0420 - 35-00 - -
16502 - Engine Coolant Temp. Sensor (G62): Signal too High
P0118 - 35-10 - - - Intermittent
I'm going to change the Temp sensor, but will I need to log to check the lambda sensor, or could the coolant sensor be causing the efficiency problem?
Also I got codes 01271 and 01596 a few times, but the aircon/heater all seem to work fine?
Thanks for your help!
Mike
