Got a whole bunch of faultcodes yesterday 2.0tfsi

[AudiCoupe]

I suddenly lost all my power yesterday. The car barely accelerated at all in 2 gear!
After awhile I got the power back.

I got the following codes:
P0245 Turbocharger Wastegate Solenoid A Low
P0458 Evaporative Emission System Purge Control Valve Circuit Low
P0034 Turbo Charger Bypass Valve Control Circuit Low
P0245 Turbo/Super Charger Wastegate Solenoid “A” Low
P0037 HO2S Heater Control Circuit Low (Bank 1 Sensor 2)
P0031 HO2S Heater Control Circuit Low (Bank 1 Sensor 1)
P30XX Fuel and Air Metering and Auxiliary Emission Controls (P3087)
P22XX Fuel and Air Metering and Auxiliary Emission Controls (P2293)

I have been have been getting the code P0299 before but now I got a whole bunch!

Anyone got any ideas what could be causing this powerloss and all of these codes?


EDIT!!! All codes but P0299 dissapered after I found 2 relays swiming in water in the ECU box and replaced these two and the lid to the box.

Soooo.... Your car was throwing codes you ignored and your wondering why it suddenly throws tons? You blew your DV.

No I did not ignore it... I changed my DV last week so I do not think it's the DV! But I've got the P0299 code after changing my DV also.

I changed my DV to the new one last week too. I only get the p0299 code when I floor it and the rpms go near redline. I'd like to find more things on my engine to check. It is also a 2.0T and a Tiptronic.

I've got rid of all codes but one. The one I still get is P0299- underboost and I have changed DV, PCV, N80, N75, MAF and a coilpack.
The only thing I can think of now is a boostleak or a cracked turbo. I did a pressuretest and did not find any leaks but I'll have to redo that with some better equppment to make sure but I have also noticed what could be a crack underneath the exhausthousing on the turbo (I can se this with a mirror so it's hard to tell if it's really a crack or not.

>daudic< one common cause of underboost is broken PCV or N80 valves so startof with these. Search the forums for more info on these.

ur diverter valve is toast...If it was running with a bad DV for while you have to take it to the shop because the turbo might be toast or some other mechanical part becuz runnig ur car without boost stresses out the engine and messes with the turbo. I ran mine with the code for 3 months before fixing it thank god Im safe.

[AudiCoupe]

No my DV is not toast!
I have changed it and both the new one and the old one is in good condition so thats not the problem.

Bump! Any updates to this thread? I just got the same codes yesterday and here I am running into this thread. I have a forge dv so I doubt it's the dv. AWE FMIC just went in so negative on boost leaks. PCV= 034 CC. Help would be appreciated.
