Audi A4 2.0t breakdown

[georgeh]

Having tons of constant problem with the A4 2007 2.0T, the first major problem I am concern about is the radiator fans are not turning on, I have tested the fan separately and works. The error codes I am having are.

08801 "Turbo Boost pressure not detected"

01152 "Cooling/Fan Control Circuit"

01670 "EMC/PCM Power relay Control Circuit Low"

00275 "Intake Air Temp Sensor/Bank/Circuit High"

05634 "Power Supply Terminal 30 Voltage too low

01109 "Evap Emissions Control System Gross Leak"

Some observations that were made is, front dash temperature gauge is inconsistent, when putting gas in, the car has trouble starting, the lack of "turbo" like ness, the ECON button is always on and can not be turned off (I know I lost all my Freon so I believe, that is what causes this), Engine light comes on SOME trips, the fuel cap notification comes on even though, for a fact it is closed.

Any help or tips will be greatly appreciated!

1. Check your battery and alternator.
2. Replace the battery or alternator reset codes. Check codes again.
2. You need to get your thermostat replaced. Get the timing belt done with it. This is causing your radiator to not turn on. You may have overheated your car already.
3. You could have blown your head gasket along the way. I don't know inspect it all

Check this out for the econ light problem. When mine wouldn't turn off and was blowing warm air it was the high pressure switch. There's a couple threads if your search google....

How did you get your B7 into such a bad state? It sounds like you have multiple serious problems with it that will take a lot of money and time to fix...Hope you haven't been driving it like that in the mean time and it is only a project car?
