Car starts and it shuts off/loses power


Asked by 1sys Jun 20, 2013 at 12:44 PM about the 2003 Audi A4 1.8T Quattro

Question type: Maintenance & Repair

I have a 2003 Audi A4 Turbo.93K on it.
When I start the car, the engine starts and as the RPM gauge goes up, it just goes right back down, the car shutss off, as if it can not stay on, sometimes its starts, but 95% of the time it needs more than 3, 4 times to try until I ge tit going, sometimes 6-8 tries. I wen to Audi, they replaced a sensor or two, a new car starter and still nothing.
I would like to ge this fixed, it is anoying and embarrasing when yo iuare at a parking lot and you need to to try 5 times to get it started.
There are no gas fumes/smell

any advice would be greatly appreciated,

Did the replace the Mass airflow sensor? How about the idle air controller?

1 out of 1 people think this is helpful.

I have no idea.. I will call and ask them... this was 2, 3 years ago. But those could be the issue?? Also, I I have no check engine light on. Thanks, Rez

sounds like evap canister valves went bad

could be lot of different thing though: high press fuel pump, water in the gas ( ethanol absorbs water ), airflow sensor, idle air control valve, evap vent valve stuck open, fuel press reg


you my friend most likely have a vacuum issue. \n check out these few options 1. loose or faulty electrical connections at, Distributor, coil or alternator. 2. Insufficent Fuel reaching the fuel injectors. vacuum leak at the gasket between the intake manifold/plenum and throtal body. 4. intake air leaks, broken vacuum lines. 5. Contaminated fuel. I have the haynes book and it lists off most comman issues and that is what it reads try that out and see if you can find an issue. my 1998 audi stalls in high heat where its ran for some time then left to bake in the sun normaly i jsut have to shut the key back turn it on which my foot to the floor on the gas peddle till it starts and it ussaly runs fine after that.


Guys, thanks for all the input. Now, I am making a list of the potential issues that you guys mentioned, and i am going to my local mechanic and ask him if he could pinpoint which one needs fixing... is this a good approach? Obviously I can not replace/fix all those parts, $$$$. Any other way to approach this without breaking the bank?


well what you can do is get hte garage to check the fuel lines pressure its really not to expensive, checking hte vacum lines is easy enough if you remove the engine cover, and if you can get the engine running all you gota do is spray the lines with soapy water and find the bubling ones and replace as you go. if you got a telescoping camera you can use the same spray soap with the throtal body its located normaly at the back of the engine under the main vacum lines. and as for checking the fuel just try changing the fuel filter it is most likely cloged if you have not changed it in over a year or so and use a volt meter on the coil pack or just pull a plug put it next to some metal at the tip and give a quick crank this is best checked in the dark
