The car also I have an 01 Audi a6 Quattro, complaint was that the car Instead, they have 2 extra pins on the injector and inside the is a resistor that has a value that matches the manufacturing tolerances of the injector.2001 Audi A6 Quattro 2.7L convertor VIN: WAUED54B01 Some earlier Denso injectors do not have coding or classification. This code will normally be marked on the top of the injector. This is basically telling the ECU the type of injector you have fitted and the code will be the same for all 4 injectors (the code is not unique to each injector like the IMA/IQA/QR codes). So, if you replaced the injectors and you are fitting a different class you need to tell the ECU this. This is a single digit code and for example, a 2008 Ford Mondeo could have injectors fitted that are class 6 or class 5. And some Bosch and some Siemens/VDO injectors use a single code identification process for injectors called injector classification. Some earlier common rail injectors have no coding. New injectors to be coded to the engine control unit. Fitment of replacement injectors will require the This data code allows the engine control module to correct the pulse duration applied to each individual injector to maintain optimum performance. The data code is programmed into the engine control unit identifying to which cylinder the injector is fitted. To as the C2i code, IMA/IQA code or QR code depending on manufacturer.
Slight difference between target flow and actual flow can occur due to high operating pressures.Ĭertain common rail diesel fuel injectors require calibration during manufacture or overhaul on a specialised diesel injection test rig to produce a data code relating to the characteristics of each individual injector. The fuel injectors are machined to very fine tolerances but because of individual characteristics such as friction, pressure drop, magnetic force, wear during service etc, very slight variations in flow can occur. The amount of fuel injected is proportional to the injector duration (opening time), fuel rail pressure, fuel temperature and fluidĪ target value for injector duration under specific conditions is programmed into the control unit (ECU) engine control map.
