Elektronische uitlaatklepactuator voor het sportuitlaatsysteem, gemonteerd op 2.0L AJ200 en AJ20P4 benzinemotoren.

De actuator bedient de uitlaatbypassklep binnen de sportuitlaatconstructie. Door de klep elektronisch te openen en te sluiten, moduleert deze de uitlaatstroom, de tegendruk en het uitlaatgeluid, waardoor de bestuurder de geluidsmodus kan selecteren op voertuigen die zijn uitgerust met de sportuitlaatoptie.

Frequently asked questions

What does the LR177878 electronic exhaust valve actuator do?
The LR177878 drives the bypass valve inside the sports exhaust system on 2.0L AJ200 and AJ20P4 petrol engines. Opening and closing that valve electronically changes exhaust flow and backpressure, which is what produces the driver-selectable exhaust note on vehicles with the sports exhaust option.
Which vehicles does this actuator fit?
It's confirmed for the Discovery Sport from 2015 and the Range Rover Evoque L551 from 2019, both with the 2.0L AJ200 or AJ20P4 petrol engine and the sports exhaust option. Vehicles without the sports exhaust have no bypass valve, so the actuator doesn't apply.
Are there alternative part numbers for this actuator?
Yes. LR177516, LR137008 and LR117492 are listed as alternatives to LR177878. Actuator specification changed during production, so check which code your vehicle's exhaust assembly carries before ordering rather than assuming all four are interchangeable.
What are the signs the exhaust valve actuator has failed?
The exhaust note stops changing between drive modes, or an exhaust system fault appears on the diagnostic system. A seized valve can stick the exhaust in one state permanently. Corrosion at the actuator's connector and linkage is common, given where it lives under the car.
