An exhaust gas catalytic converter performance guarantee is granted for a period of 12 months or 50,000 km, whichever comes first, subject to the following conditions:

• The car is powered exclusively by unleaded petrol;
• The car is originally fitted with an exhaust catalytic converter;
• The catalytic converter has been fitted at a specialist diagnostic station or exhaust replacement workshop;
• The faults that had a direct impact on the damage to the catalytic converter have been removed;
• When replacing the catalytic converter due to natural wear and tear (80,000, 100,000 km), the Lambda Probe should be replaced at the same time;
• If it is necessary to insert a connector before the catalytic converter, only stainless steel pipe connectors should be used and attention should be paid to the tightness of the entire exhaust system;
• The catalytic converter is used strictly in accordance with the specified engine capacity and the dimensions of the catalytic converter to be removed.

No warranty is given for mechanical damage to the catalytic converter and when the car is running on gas.

Any warranty card without dates, stamps, signatures and with corrections and deletions shall be invalid. In the event of defects in the operation of the catalytic converter, this is solely the fault of the manufacturer, the catalytic converter will be replaced at the point of purchase on presentation of a valid warranty card and proof of purchase. In case of loss of the warranty card AWG POLONEZ Company does not issue duplicates.

The AWG POLONEZ recommendations must be strictly adhered to, no “push” or towing starting is allowed;

• Do not check engine operation with the ignition cable ends removed;
• Replace spark plugs according to the car manufacturer’s recommendations, every 10,000 to 15,000 km on average;
• Check for system malfunctions indicated by the “mi” – Malfunction Indicator light – a flashing light indicates the presence of a “no ignition” fault, which can cause damage to the catalytic converter;
• Check the high-voltage cables;
• Change engine oil according to the car manufacturer’s recommendations and periodically check engine operation at a specialist diagnostic station.

The three-way exhaust catalytic converter has been designed to comply with current standards for the emission of toxic gases into the atmosphere.

To comply with the standard, four types of diagnostics must be used in the engine control system:

• catalytic converter diagnostics – makes it possible, via the diagnostic memory, to determine the efficiency of the catalytic converter;
• power system diagnostics;
• misfire diagnostics: the system is able to diagnose misfires, which can cause damage to the catalytic converter or increased emissions;
• lambda probe diagnostics: makes it possible, via the diagnostic memory, to determine the correct functioning of the lambda probe.
