Turbo wastegate

Turbo wastegate
hey there fellow mini addicts.
just got back from the shop after finally tracking down the cause of the dreaded “reduced power” half-engine light. Only seems to come on while on the freeway and under a light load, like going up a small incline. Well it turns out that my waste-gate is hanging open and I’m losing boost! Does this really mean that I will need to replace my whole turbo? Is there not a way to just fix the waste-gate? This is my first turbocharged vehicle, so it’s all new to me. The price of a new turbo is unfortunate, but not a deal breaker. My biggest issue is the 10 hours of labor they said it will take to do it.... I’m not cool with paying over $3000 to have a new turbo put in!
so on to question number 2... if I do need to completely replace the turbo, is this something that a guy can do himself to save some cash? I’m fairly handy and do a lot of my own maintenance on my other cars, how tough of a job am I looking at here?
any help of suggestions would be greatly appreciated. Also if anyone has suggestions on what one to get, and where to buy it, I am all ears!
Thanks in advance

Depending on the year and mileage of your Mini, it might be covered under warranty: Mini turbo extended warranty. Unfortunately it's the surrounding exhaust housing that wears out preventing the wastegate from fully closing. It, (exhaust housing) is a separate part of the turbo but would probably be wiser to go ahead and replace the whole turbo along with the oil feed line. That's what I ended up doing last October with a lightly used unit and was able to remove and replace it without putting the front end into the "service position". Yes, i saved money doing it myself and buying used but wouldn't suggest this route if not mechanically inclined. Good luck.

So I just got off the phone, the first person I spoke with played dumb, the next said mine wasn’t covered as it’s VIN specific. I said well from what I read it looks like almost all turbocharged N18 engines would be covered....and guess what motor I have...with a bad turbo?
after some run around, they want me to take it to the mini dealer in Seattle and have them diagnose it (even though I just paid for that yesterday at a different shop) and then they will try to do something about it. I have an appointment for Thursday the 31st, to have the diagnostic done again at Seattle MINI. Fingers crossed. If anyone has any advice I will gladly take it!
to their credit, the folks on the phone at Seattle Mini were really nice and helpful.
i really hope it’s covered, I can’t afford 3 grand for new one to be installed.

Don't give in to the typical dealership BS stories because they all hate doing warranty work, (doesn't pay as much as the regular hourly rate). I used a vacuum pump and inspection camera in the O2 sensor hole to verify that the wastegate was the issue. These N18 wastegates have a high failure rate because it has a much higher duty cycle than your typical turbo wastegate. It's not a matter of "if" but "when" it'll fail. Unfortunately mine was out of the warranty period due to mileage. Keep us posted of how things transpire.

Minor Update
well I dropped it off this morning, they said I may not hear back until Tuesday, but I’m ok with that because they gave me a shiny new 2018 Countryman S to drive until then
Dont know anything yet, except that I need a new turbo....but they sounded fairly optimistic that Mini would look out for me....we’ll see

Yes, replacing a turbo is not as crazy as it sounds. Part for part its pretty straight forward. Hardest part would be putting your Mini into service mode.
REMOVE:
If you don't put the Mini into Service Mode you will curse out everything under the sun and its very difficult to get to the Exhaust Manifold.
Make sure you have an oil/coolant catch to be put under the turbo and at least 1 gallon of replacement coolant and a quart of oil for after you are done with the install.
Check the Manual for Torques and tightness
REMOVE:
- OEM Heatshield
- Oil Lines
- Coolant Lines
- Boost Vacuum Line
- Wastegate Vacuum Line
- 4 Bolts for the Exhaust Manifold
- 3 Bolts for the Downpipe

This is the Waste gate Vacuum Actuator. if this piece or the line to this doesn't hold the vacuum it will not close the waste gate
This is the Actuator Arm that closes the Flap (circled in red). Also if the nuts for the Flap lever are off will also cause it not to close completely (circled in yellow) this is highly unlikely but not unheard of.
This is the flap that needs to close to build boost which in turn builds the power for your Mini (or any turbo driven car) (Circled in Red). While the flap is open the exhaust gases which would be used to spin the Compressor wheel will just flow out through the Downpipe

Fingers crosses! If they won’t I’ll be buying one and trying to install it myself (with a little help probably, heh heh)

The actual wastegate valve and shaft on which it rotates on are all part of the exhaust housing and usually not separate parts. Like I stated in a earlier post, you can replace just the exhaust housing, (that includes the wastegate mechanism) but probably should go ahead and replace the whole turbo do to mileage. Does it sound doubtful the repair dealership is gonna honor Mini's extended warranty?

the part I posted is the vacuum assist to close the waste gate. If that part is defective which is not unheard of then it is a part that you can replace with a little elbow grease.

Update
Just got the car back, like I thought the turbo needs to be replaced. As far as the warranty goes.... I have to call MINIUSA tomorrow. But gut feelings say that I’m probably on my own.
If that’s the case I’m thinking about getting a hybrid quick-spool turbo and doing the work myself. Just can’t stomach paying for almost 10 hours of labor on top of the cost of the turbo itself.
I also just found a place about 40 miles from me that rebuilds turbos, so I’m going to look into that as well.
Thanks again everyone, your help is invaluable to me right now, and if anyone has any suggestions or advice or anything, please post it for me.

Supposedly, MINI USA sent out a letter to potentially affected N18 owners for the turbo extended warranty. I didn't receive the letter and I know MrGrumpy didn't get one so I would be very interested in reading the details. Did anybody reading this post get an actual letter?
