Question about 2002 Audi A4

1 Answer

My 2002 audi a4 3.0 has trouble starting after it has warmed up. my guess is the fuel pump is lagging. it idles all over the place once it finally starts. i have to rev it up for a bit to get it back to normal. it runs fine after that.

It is either with your injectors or fuel pressure. Check your pressure and injectors. Try one of those injector cleaners. If that doesn't work check the pressure in your fuel lines. It has to be constant at all times.

Check if there is a lag in the needle of the tachometer when you step on the gas when in gear and when in idle. If there is no lag or anything unusual while the engine idles, it may be the transmission. It may be the clutch for manual transmission or the torque converter for the automatic or you may need to add or replace transmission fluids.

Car takes a long time to start, like a few minutes. Runs fine once it finally starts. It gets closer the longer you crank. Changed pugs, fuel filter and some vacuum/pcv pieces, No difference.

You haven't changed everything...map sensor controls spark and fuel mixture as does the throttle position sensor, also check the idle control valve...Don't just buy stuff...do testing first.

Faulty fuel pump?


i would recomend you to sell your audi as fast as you can before its too late, audi is a very bad car, hasnt had any good reviews at all and in cars, its really luck if you dont have any problems with them. sell it and buy a new car, you can get a new one at a good price, the most important thing is that it will be new, keep that in mind ! good look

Changed transmission and ever since then it keeps stalling once warmed up


More than likely something was disturbed accidentally,a connector to a sensor,a sensor itself,possibly even a vacuum line,although a vacuum leak will usually result in a high idle,but an engine that wants to stall,so visually check all these items.At this point,i would do the visual checks,and also scan the vehicle for any possible trouble codes,as a trouble code will point in the direction of the problem.Places like Auto Zone will pull the codes for free.
