Hey,
I've had my A3 1.8 now for 4 months with no problems what so ever!
But now, after i've left work something has happened. When i first started it after work it wouldnt idle at all, fire uit p then it would just cut out.
As the engine warmed up and the automatic chokewent off the revs went erratic when idling, reving between 2 1/2 and 3 1/2. But then when i approached a roundabout the revs went again and it cut out. I did notice when the car was giving the erratic revs thats there seemed to be a bit of play on the accellerator peddle, also when applying a little pressure to the peddle the car would be rev up alot. like there's a lot of fuel going in.

Any thoughts please?

 

check all vacuum lines are secure

 

Sorry, forgot to mention its the 1.8 v5 not turbo.

Would vacuum lines apply then? I aint no mechanic, so just takin a guess.

 

vac lines will cause loss of air volume if damaged and suck too much air in thus altering the fuel air mixture

 

Thanks for your help, will get machanic friend to check in the morn while i stand around and point nodding my head occassionally saying "yeah, yeah. I know what you mean!".

Just curious. If your A3 is 4 months old, isn't it still under warranty? If so, why bother trying to figure things out yourself, just take it to the dealer. Dealing with the problem on your own may even void your warranty.

 

Because i havent bought the car from new, its 4 years old. If it was still under warranty i'd be laughin!
