Mercedes CLA exhaust flap issue
Discussion
Afternoon all,
Hoping someone on here can help with an issue some family friends have with their 2015 Mercedes CLA diesel. Dash is showing an error code and they took it to a main dealer who diagnosed a fault with the "exhaust flap actuator". Apparently this is part of the AMG pack the car has, god knows why you need an exhaust flap on a diesel car but there you go. Having charged around £120 for the privilege of plugging the car in to get the code read, they have quoted circa £600 to replace the actuator. I'd like to help them out if I can, I'm hoping the actuator valve can either be had considerably cheaper elsewhere and I will fit it for them, or even better if there is a way to bypass the actuator and fit some sort of blanking plug/termination block to the loom so that the car thinks the valve thing is "ok" and won't throw up an engine management light on the dash. Apparently the car drives fine with no difference, the main concern is that the constant dash light will obviously hide any other faults that come up and will be a problem come MOT time.
I've been googling but struggled to find any cheaper suppliers of the part, or a way to bypass the valve specifically for a CLA diesel. It seems that some of the petrol AMG's can easily bypass the valve just by disconnecting the loom to the valve and no error code is thrown, but I cannot find anything specific to the CLA.
I would be very grateful for any help or advice

What code has is actually set?
Not sure, they live around 100 miles from me so not a quick trip for me to plug my cheapo fault reader in. I will ask them if they can get the code from the dealer and will post back here. To be fair, the dealer sounded fairly helpful; when my family friends said I could probably do the work for them to save them some money they volunteered the part numbers for the bits needed without even being asked.I will post back when I get the code, thanks again
