Description
Catalyst for CITROEN C1 PEUGEOT 107 cars with 1.0 i 50kw EURO5 engine
From a car with an honest 68,000 km
The catalyst is intended for PSA Citroën and Peugeot cars with a 1.0 i (1KR) petrol engine with a power of 50 kW, emission standard EURO 5. It is a used part from a car with a documented mileage of approx. 68,000 km, suitable as a replacement in the event of an error message on the effectiveness of the catalyst, increased emissions or reduced performance. With searchable OEM codes, customers can often find it directly by part number and quickly match what they have on their car.
Technical information:

Installation recommendations:
– Before assembly, check the tightness and condition of the flanges, contact surfaces and threads (especially the threads for the lambda probe).
– It is recommended to use new gaskets and fasteners (nuts/screws), or new springs according to the design of the exhaust.
– Mount the lambda probe with sensitivity and the right moment, route the wiring away from the hot parts of the exhaust.
– After installation, check for leaks in the exhaust (hissing, smell of exhaust fumes) and, if necessary, delete the error codes in the diagnostics, if they have been stored.
The reason why the part most often goes wrong:
The most common cause of damage to the catalyst is long-term poor combustion (missing ignition, rich mixture, faulty lambda probe), when unburnt fuel gets into the exhaust and the catalyst overheats. Another frequent cause is mechanical impact damage (contact with the road) or internal disintegration of the ceramic insert due to thermal shocks.
