Did you find out what the problem was Chris? I have same code (P22D500) along with P22D300
Orange Coil light keeps coming on and goes into restricted performance.
Bi-Turbo 204hp (CXEB) DSG, 4motion, 2018, 42,800mls.

Hi yes it was the vacuum solenoid valve and a leak . I tested everything and end up replacing these solenoids and immediately sorted . I had tried everything before this and not got any results. Hope this helps you .
Well done.
Thats good info and exactly what I'm hoping mine is. Are these vacuum solenoid valves the 3x valves (on a bi-turbo 204hp) staring you in the face when you open the bonnet and they're attached under front edge of bulk head?
Picture grabbed from internet... solenoid valves circled in red

Did you also have symptoms like sluggish reaction from the engine? in other words just plain slow?
Yes it goes into what I guess is limp mode. When this happens I found it more driveable to switch to manual gears on the DSG and keep it in a gear of 2000rpm or more.
If Coil or Engine light resets after switching engine off then this resets the limp mode too.

Yes could be an Actuator diaphragm as well.
Hoping mine is just a faulty N75 solenoid valve, there seems to be 3x on the 204hp. Running some tests to work it out which one it might be if any!

Do you know if the 180hp CFCA has multiple of these selenoids? i can imagine it has 2 (one for each turbo)
thats one of the solenoids on my 204, just about read the part number, if it any help.
in my own case, goes to mechanics this Friday, to partially strip down the turbo, check where the problem lies, to be fair solenoids look like theyve had a hard life above a hot engine, could be those that needs replacing, we will see......

On my 204 (2018) the right hand solenoid is an N75: IK0906627E "7.02184.00" the middle and left hand solenoids have the same numbers... IK0906627A "7.00868.00"
Found these diagrams courtesy of "Dellmasive" in another thread. Thank you very useful.

Hi sorry for the late reply. That’s exactly the 3 x solenoids. I just replaced all 3 . They are not that expensive at all but it solved the issue instantly. Well worth a try . If I can be of anymore help please let me know .
Does anyone know what the difference is in the 3x Solenoid Valves? 1 (N274) & 2 (N529) have the same numbers stamped on them but 3 (N75) is slightly different. I was hoping to try the new N75 valve I have purchased in all 3 positions, starting with swapping over number 3 first to see if it solves my fault code issues.
Hi I’m not sure what the difference is but I changed all three and had no issues after . I may have got away with replacing one but I was at that point where I didn’t know what else to do so for the sake of it just replace. Double check your vacuum pressure in case you got and leaks etc . If no leaks and all replaced everything should be good. Let us know how you get on please. Thanks again
Ok a new N75 solenoid didn't fix the issue, so used the VW Roadside assistance (AA) and it's gone into VW under the extended warranty All In plan...
I guess it's the Actuator on the inlet valve. Will get a call next week from them...

it didn't! stripping down the turbo is the next option, possibly an actuator issue? Mechanic rang TPS for a price, they quoted for a whole turbo that includes actuators, I'm assumming this means they cannot be replaced, only as part of the complete unit?
