Malfunction of exhaust gas recirculation (functional chain) (P0400) Incorrect routing may cause throttle lever to jam. Note length and routing of vacuum line from intake manifold to EGR vacuum transducer (Y31/1). Remove exhaust gas recirculation valve (89).Unscrew exhaust gas recirculation pipe (89) from cylinder head.Dismount EGR line (89/1) from intake manifold (19).Unscrew union nut (89/3) on exhaust gas recirculation valve (89).Detach vacuum line (b) to vacuum unit (89/2) and EGR pressure transducer (Y31/1).Unplug connector on EGR pressure transducer (Y31/1).Remove engine cover with integrated air filter.The vacuum acts partially or fully at connection OUT and operates the ERF valve accordingly.ĮGR intake gasket. Signal from control unit: The valve unit opens proportional to the current flow in the coil.The exhaust gas recirculation valve is close (ventilated). No signal from control unit: The connections OUT and ATM are linked.Influences via the coil anchor the valve unit as follows: This unit is actuated by the ME control unit with a pulse width The controlled vacuum flows further via a hose line to the following Line with engine speed and throttle valve position via a control Pressure regulator, which stabilizes the intake manifold vacuum in VAC - Vacuum supply from intake manifoldįrom connection VAC the intake manifold vacuum reaches the.ATM - Atmospheric pressure, air admission via cylinder head.f - Electromagnetically operated valve unit.d - Hose line (guides controlled vacuum of approx.In line with this, the ME-SFI control unit meters less fuel. The inducted air mass is reduced by the quantity of exhaust gases recycled. Consequently, the fuel-air mixture has a lower Gas recirculation valve, depending on the cross-section of the Impairing engine running or exhaust emissions.Įxhaust gas low in oxygen content is drawn in through the exhaust This case as much exhaust gas as possible is recirculated without The performance map is designed to optimize fuel consumption. Coolant temperature between 60☌ and 110☌.The ME control unit as soon as the following conditions are met: The exhaust gases are recirculated in line with the map stored in Quantity of exhaust gases that are recirculated. Mbar, and is opened to varying widths in order to control the The EGR valve is actuated with a vacuum of about 80 to 200 Unit with a PWM signal, which has a frequency of about 10 Hz The EGR pressure transducer (Y31/1) stabilizes the sharp vacuumįluctuations in the intake, and is actuated by the ME-SFI control The exhaust gas recirculation valve (89) is combined with anĮlectrical EGR pressure transducer (Y31/1). b - Controlled vacuum from EGR vacuum transducer to exhaust gas recirculation valve.EGR delete accepts no responsibility for the use of this part on the public roads. The ECU may also require a digital delete to stop the EML light coming on. If you would like us to check compatibility please send us your reg and we will double check on the system.

It comes with full instructions and includes the following components: The kit allows you to completely remove the EGR valve and EGR cooler from the engine. The kit can be fitted quickly and simply provided you have some basic skills and tools, alternatively you could take your vehicle and the kit to a garage and have them fit it for you for a small fee. This EGR valve removal kit allows you to completely remove the EGR system from the engine.
