Hello all and i would like to say what a flipping good car the audi is, im a new owner to a nice 2006 model a3 3.2 v6 quattro, with DSG.
Now apart from not know what the service intervals are for DSG which i need to know as i will be performing the service myself here in zimbabwe

i also have a constant and irritating cel coming on.
I get the following codes when i check with the launch .
08592 P2190 system too rich at idle bank2
08584 P2188 system too rich at idle bank1

Im not sure what could be causing the cel but from what i have been reading it might be the air flow sensor ?
Please can any one else with experience maybe chime in would really appreciate it, as for starters im miles away from a decent Audi service center, and i would like to resolve the isssue with out having to drive to JHB to fix it .
Many thanks in advance.

It could be the lambda sensors in your cat there are 2 one from each bank

Or you're cat could actually need replacing or there is an emissions problem elsewhere

hey imagine that a response in a heart beat, i called the audi workshop in Johannes burg earlier today and the very kind engineer/mechanic said it might be the coolant temp sensor ?
Now when i clear the light i can drive the car sometimes for a complete day before the engine check light decides to come on, and it only ever shows its head at coasting speed or part throttle thereof .
So im not sure what could be the root .
In the morning after clearing the cel it never ever comes on and then drive her for a bout a day only for the light to come on when i am saving fuel at part throttle.
Beat the crap out of it after a cel clear and the light doesnt come on ?
Im super tired will wait for a nice response

Thank you in advance once again
.

im using a launch by the way to diagnostics .

Actually could be a faulty temp sensor as if its faulty it may cause the car to run rich as such the EML will come on as both lambda sensors probes would be reading high

It's unlikely to be a faulty probe as they are both reading high, a faulty probe would just be reading one wrong

Could also be the coil packs

DSG service is at 40k intervals no exception, for the price of a temp sensor I would change that and see.

Duplicate post iPhone gone mad lol

Don't think it would be coilpacks mark, more likely to be MAF I would say

Could be, but when mine went it threw up different errors,

If it is a coil pack the car will be hesitant / misfire and its the resultant Unburnt fuel that the lambdas pick up and flag the EML so this should be easy for you to rule out as you would notice the above

Hey guys thank you for taking the time to respond, i have ordered a new temp sensor, will see what it does after it has been fitted.
I dont think it would be a coil pack the car drives well and has loads of power until today where i noticed something .
I usually get around 11kms/ltr and today with the same medium driving i was getting 8kms/ltr and this was with the most cautious long term driving i have done figure didnt change .
So i checked the exhaust and there was some moisture on the pipe... meaning a rich mix .
Never the less the car has great power idles nicely and runs great through the gears with out even a stutter.... id be more inclinded to thinking it was temp sensor as AFM usually when packing in does strange stuff and causes hestitations and surges, have owned a few fair subaru's and japanese cars to know the symptoms.
These German cars a different and the tech is way better in terms of monitoring everything, jap cars will run rich and the ecu will smile at you and say everything is ok mean while u are using fuel and making oil ( adding unburnt fuel to the oil) .
Thanks once again will change and revert for the purposes of other users getting info in the future regarding the error .

Ps what of haldex and filter when does that get serviced ?

 

[MIQ]

With the lower MPG that points towards a faulty MAF

Also the faulty ECT will use more fuel

Also the haldex oil in yours in every 40k as is the dsg

Filter is 40k oil is 20k for the haldex

 

[cuprabob]

Filter is 40k oil is 20k for the haldex

That's for the Gen 1 Haldex. A 2006 A3 will have a Gen 2 Haldex the same as a MK5 so it's 40k for oil and filter, although VW don't actually say you need to change the filter, but best to do.

Apologies :-/

Hello, and many thanks for thanks for all the info, will try and get this sensor first and see what happens after, is there no way of telling if the sensor itself is actually faulty, surely the launch system should be able to tell based on the read outs ?
Im going on a guess here ?
On a jap car there is no way of telling but Afm sometimes can cause the same problems as well, just that on a jap car it doesnt tell you anything about a rich mixture etc .
