2009 a4 no power

[aprb8]

Hi everyone
I got a 09 audi a4 and its got some problems I cant figure out on my own.
I bought this car with all these problems.
any help will be greatly appreciated.
first off its a 09 audi a4 2.0t Quattro with apr tune
its throwing 10 codes through vagcom
P0444
P2008
P0243
P0010
P2400
P2401
P0458
P2009
P0245
P2008
Here are some things going on with it. The car seems like its in half power and when I give it gas it seems like the turbo is not spooling.
Also the transmission will not shift if I floor it but only when i floor it. When I put it in manual mode the car seems to drive a little better but still no power.
I checked all the vacuum lines and found that the wastegate on the turbo has a hose not hooked up to anything. I looked every all over the engine bay to see where it could have been hooked up too cant find anything. Also the car sounds like its got a after market loud BOV but i looked everywhere and no sign of aftermarket BOV anywhere. Im stumped and would appreciate any help you guys can offer. Thanks again

Yikes. Want to elaborate on those codes? Maybe run them through google and post a short description.

P0444 EVAP purge control valve (n80): circuit open
P2008 intake manifold flap bank 1 electrical malfunction
P0243 solenoid valve for boost pressure control (N75) malfunction
P0010 bank 1 camshaft A (intake) position actuator malfunction
P2400 EVAP leak detection pump control circuit malfunction
P2401 EVAP lead detection pump control circuit short to ground
P0458 evap system purge control valve (N80) short to ground
P2009 Intake manifold flap bank 1 short to ground
P0245 solenoid valve for boost pressure control (N75) short to ground
P2008 bank 1 camshaft A (intake) position actuator short to ground

I checked wiring and there are no torn wires or broken connectors to any of the valves or sensors

i would start by swapping out th n75 valve for the latest version n75. removal and reinstall took about an hour from the top.

old n75 had weaker interiors. new design is "piston" based. basic handtools nothing crazy.

replace the n80 as its easy to get to and cheap as well.

is there anywhere online i can get the two valves? or is it dealer only

[aprb8]

ok looked at the n75 valve. Every one i called says its has 3 vacuum lines hooking up to it. mine has only 2 there is no 3rd connection on the valve

[nycaudi]

can you post a pic? my n75 deff had 3 "ports" and 3 hoses. your loose wastegate hose should link to your n75. 1 problem fixed.

or even just google one of our cars....find the missing hose and reattach with a hose clamp

I use several sources online depending on their price. these parts are typically dealer only


hopefully this is nothing serious. if you reconnect the n75 should kick in your turbo and the n80 should clear your other shit up

ordered a new n75 valve costing me $41 which is not bad for audi lol
turns out the valve has to have three hoses coming out so i got a broken valve.
will update Monday when i get the new valve. thank for all the help so far

[nycaudi]

np bro
whered u order from?

[nycaudi]

buy screw clamps....the stock ones are bitch and are not as tight once u pry them off

your bigger concern shuld be why the apr tune blew off the spiggot on the n75......too much pressure? idk I would look that up to prevent you from blowing another n75 @ the ecus current settings

I got it from carquest with business discount. the dealer wholesale was $56 they had in stock but they are 45min away each way. everyone else I had to wait till mid next week and carquest should have it by mid Monday. plus the store is literally around the block from my shop. and yea I figured with the clamps too lol. I think the guy who sold it to me messed with the car and broke it off with the hose off because the clamp was loose and there was no broken piece of the valve inside the hose so I don't think the apr tune is the problem. but ill update Monday if this is the only thing that's throwing so many codes. thanks again guys

sorry for late update we got iced in last night so I got home late
so... I changed the n75 valve. its oem same as dealers. seems like it got a little more power but barely noticeable
still same codes. I tried resetting the codes and driving and they come right up once I restart the car.
my next option is n80 valve.
