Checking a USA MB parts supplier. The MSPR is $240. discounted at $216. This item number #9 in the diagram below.
ok so i have tried installing this motor and im not having much luck. (i just now thought maybe i need to plug it in and let it rotate) If i install it like it came the exhaust flap is open and the motor does not want to close. it does wiggle some but seem like its struggling to close in the morning ill try plugging it in and seeing if it rotates and stays. any help would be appreciated
Yes the spring broke this Is a new Benz assembly . I'm going to try plugging it in and cycling the key maybe the motor came in the flap open position
Yea im thinking it was shipped in the wot position so I'll ether plug it in and see if it moves which it should go to closed if its in the open poison or I'll get out the power probe
huey when you installed yours was it in the closed position?
ok so i marked where the spring was located and plugged it in. key on did nothing but once i started the car and gave it some throttle the motor turned in a different location than it was previously and stayed in that position. now with the flap in the closed position the motor bolts right up
Dealer wanted $1600 (WTF??! ) to replace my actuator, so I did some more Googling and found out this exact same actuator is used in many brands of cars from Audi to Kia to Dodge. Then I found out Mopar sells just the replacement spring for around $30-$40. I ordered off of eBay, but it's available just about anywhere, including your local Dodge dealers if you're in a hurry. Just got it in today and it's an identical replacement. Part number is 68319331AA.
Hope this helps someone! View attachment 28106
=========Hi need to replace the actuator on my exhaust flap on my 2015 CLA220 should the flap be open or closed?
Did you bench test it prior to installation? The actuator powers open (12V @ ~WOT) and spring closes the exhaust flap. So it "fails closed." Although a new part perhaps it's defective? The spring is usually the culprit as discussed earlier in this thread.
Did you procure the Benz or similar Audi part?
Again, you may be better served first bench testing it, even tho' a new part, with a 12VDC source to see that it properly electrically-opens with voltage applied and spring-closes with no voltage. Without voltage applied there is no way for the motor to hold it open. Unless again it's just a new-bad part, which although rare can happen.
In vehicle use it should only open the exhaust flap upon near wide-open throttle (WOT) so "cycling the key" won't tell you anything.
I found Germans do replacement spring only €30 bought just to see and it works https://asr-component.de/gb/begin/92-stiff-clutch-spring-sister.htmlYes . Nobody sale the spring alone. Like I said. Mercedes actuator with spring is 350euros . Audi/vw ref for exactly the same thing 100 euros.
i pulled the actuator today on my '15 gla45 and found this:

i knew it was bad when the nuts holding it on looked like this:
