02 Audi a4 quattro
I'm just wondering if my secondary air
pumb is out?...... Here's what I did, I
checked relay fuse n its good, I also tested
pumb wire connector n what happen is
there are two wire that are short like not
enough power flowing n pumb not
working.... Do I have a fuse problem?
Or my pumb is just straight out
Now all codes are gone but new code is p0243 need help
Hey I'm now having like a kick on 2nd gear n 5th gear also if I accelerate more than 125 mph it shakes like its going to die on me what could it be.....
Its like almost limping but I'm not sure....
Could it be catalyst converter or flapper inside supercharge turbo wastegate broke.... I really need help.
turbo waste gate would be my best guess
Any idea how to replace it, do u have a video of how too..... Thanks
https://www.youtube.com/watch?v=ubLIgMZijsQ google is your friend. found this video on my first search for VW wastegate replacement.
Where can I purchase these parts instead of dealer...
http://www.autopartsway.ca/ is where i order all my parts in canada. just google search auto parts audi or vw and you will get a list of parts. Just be sure your ordering hte right peices. so in other words ask your dealer parts department first cause sometimes you can get a decent deal there
OK, got rid of 4 codes N now 2 more to go.... I have a catalyst efficiency below threshold bank 1....... Could it be a o2 sensor OR N75....
Hey Deathjam how long u been working on these cars.....
this specific modal i have been working on since i bought mine 5 years ago i went out and bought a haynes manuel which helped alot. Owned a audi 5000 before that for 2 years night mare that cars fuel injection system was. any ways its most likely your oxygen sensor got cooked from the bad turbo tho i would have the cat tested or at least looked at as well jsut in case
Both primary N secondary sensors are located on catalyst... Am I right or wrong
So my second code is turbocharge waste gate solenoid a...... Is it the actuator gone bad?..... Not really familiar with this....
I watched couple of video N all they did was replace actuator on wastegate..... What do you think should I try this.... N I was wondering can I troubleshoot vacuum leak without opening anything say like rev the engine high and use a spray bottle to spray the tube connection N more, is it possible?.... Just wondering cause I don't have air compressor... Lol...
yes the sensor is mounted in the catalytic. Once the turbo is fixed the o2 sensor will straitghen itself out since the incorrect flow threw the turbo causes the issue. as long as its not been doing this for a long time you should not have to worry at the cat or sensor. your best bet for replacment in the states is http://www.rockauto.com/?a=G-autoparts they have the lowest prices and the widest arrange of parts. they even ship to canada
and as for leaks just use soapy water in a bottle if there is a leak it will show imedatly but if a pump is malfunctioning and not working then this will not work.
OK I'm now waiting for parts probly gonna take a week to get it....
Found some fix on the kicking problem.... It's some kind of ECU update along with a transmission flush....
This can be done @ dealer...
I've fixed all the above brand new but still have 1 more code p0420 but not for long I'm getting a new cali catalytic converter....
Oh n it will only cost me 400$ for catalytic converter.... Ppl dnt be fooled by dealer or autopart store save ur $1700.... There's other ways to buy cheap like shop online everything I've done order for my car was available at Amazon.com N that's where I'm getting my caty from... Unless u got dough to spend.
replace new catalytic converter N yay no more po420 code....so happy.....
next will be replacing secondary air pump,combivalve due to a po411 code that comes on N off....
catalytic converter should be california emission by the way depends on vehicle emission.
