2001 audi allroad puttering, then dying when give it gas.

this can either be a bad cat or o2 sensor its the after cat downstream driver side you can either replace the o2 sensor or buy a spacer from 034 Motorsports to get rid of this problem or get a tune alls it does is checking if the cat is there for emissions will not effect gas mileage. Owner of Audi A6 2.7T 2001.B2 S1 is drivers side pre cat

B1 = Passenger side
B2 = Drivers side
S1 = Pre cat
S2 = Post Cat Example s1:b1

Kit available from dealer

Bad gas maybe, maybe junk in tank from bad gas or it could b the cadalidic converter

Sounds like spark plug cable (s) which can be purchased individually if you know which one you need

Having the same issue right now. Did you ever find a solution?

very common fault , check the sensors value by the obd and compare on cold engine the air - water temp . it should be the same value if the engine have been parked over night ,if bad sensor the value will be diffrent on the sensors

I am not sure you are asking what you really want to know

This will be a 12 volt dc system
The battery AMPERAGE will be labeled on the battery generally some where around 750 to 900 Cold Cranking Amps
Amps will have nothing to do with charging the battery
A battery CHARGER will have a MAXIMUM amp output Most lf them are 4 to 10 amps on a slow charge

Google this "User manual download for Audi allroad" and a whole list of sites come up all with free downloadable manuals.

Hope this helps!

when the battery goes dead it looses its memory on engine settings like idle speed.. two things you can do first one is to clean the throttle bore with carb cleaner... the other is to start with foot on gas and slowly bring it back to idle... it will pick up the idle air position to keep itself running if you do it slowly... everything happens over time so as the throttle gets dirty the computer makes these adjustment on its own and when the battery dies it starts out basicly at different percentage of idle control tht it really needs because of the carbon buildup on the throttle plates

I seem to be having the same issue on my 2001 allroad. I read the post before and just tried some WD-40. I will let you know how it works.
