Audi a3 no power when accelerating

The engine stalled while I was driving my car. The power of steering wheel and brake was lost while the car was still moving forward. Luckily, I did not hit any thing. One day I was at the highway, and all of a sudden the car displays a message in the cluster stating that I was driving at low rev high speed Suddenly I lost power, not acceleration, and had to pull over. Then, heat built up, steam came out, almost as if the car was dying.

I was so scared, got late to work, then put the car to rest for a while. Got it to the dealer, they told me that the car didn't record anything They told me that even though I had that, the car was fine. If you have a for-profit service, contact us. Ask your Audi dealer.

Random loss of power, not limp mode?

Ok so I've been driving my newly acquired jetta TDI. Occasionally when going up a long hill and I get into the throttle for any amount of time usually has to be 5 seconds straight or morethe car will suddenly lose power.

However, after consulting with a good friend who is a VW fanatic, he's telling me this isn't really "limp mode". It is a sudden loss of power, quite substantial. To the point where it wouldn't even accelerate in 3rd gear going up the hill. Usually I crest the hill and continue to cruise and the next time I really need to get on the throttle again, power is restored.

I am going to try and hook up my scanner sorry, not VAGCOM unfortunately and see if I can capture a pending code or something when it's happening. I can pretty much do it on demand if the hill is big enough and all that's needed is a heavy right foot.

Everything I try searching is either actual limp mode cases, or a few cases that were similar, but power didn't come back and they found a loose intercooler tube etc Car only has k miles on it currently. I'm having about the same problem with my 04 Passat.

I see under the "How to" thread that it could be the anti-shudder valve sticking which is located by the egr valve and both are prone to clogging up. Hope that helps. Good to know Jon. I'm sure the car has never had the EGR valve cleaned.

I have the EGR delete kit sitting in the back seat, I hope to do that and the intake manifold cleaning very soon, so I will add that to my list of stuff to check.

Let me know if you end up finding out anything else of if the anti-shudder valve is the culprit! TDI s : Jetta and Jetta. When I've had true limp mode occur, its never thrown the CEL either. Sometimes there are codes that don't trigger the CEL, but I have not had any codes present after a "limp mode" event.

Although I've never known of the anti-shudder valve causing a real limp mode.I have got in my car this morning, which is an Audi A3 02 plate 1. The car has suddenly lost all acceleration boost. It is driving OK apart from this. No whistling noises, black smoke or problems when idling. I have heard that the fault may be with my MAF mass air flow meter.

I have not come across this before. I am wondering firstly, do you think this sounds like a correct diagnosis? Would you have say a used part would be OK? Or always buy new with this part? This morning I get in and its starts fine after being jumpedengine sounds fine etc. I joined onto the motorway on my normal journey to work. Put my foot down to nip into the next lane and my car basically did nothing! I pretty much had my foot to the floor and it was crawling up the speedometer.

No engine lights have come on recently. The only occurring problem I have had the last few weeks, is a faulty battery which needs replacing. So most mornings I need to jump start it! Not a problem just not got round to getting a new one yet. However I am unsure this could be linked to this new issue. If it gets clogged the engine wont perform until it clears. DPF holds the soot from the engine and regenerates through heat so sometimes you need to drive at high revs for long periods of time.

A misfire is the most common reason that your Audi A3 would be jerking while accelerating. While ignition system is the most likely reason that a vehicle will jerk when accelerating, it is not the only one. All of your exhaust has to pass through the catalytic converter to get to the tailpipe. It is possible for the converter to clog. When it is clogged, your A3 will struggle and jerk when accelerating.

This happens when the catalytic converter is almost completely full, and the engine is choking on its exhaust. Your A3 needs fuel to run obviously. If one of your fuel injectors is clogged, or not firing properly, it can cause a jerking sensation.

Outside of bad fuel injectors, a bad fuel pump or fuel filter can also cause a jerk while accelerating. When either of these go bad, there is not enough fuel pressure at the fuel rails. You should check to see if the air intake it blocked with something foreign. Or, if you have a very dirty air filter. Not enough air will throw off the air fuel ratio and make the A3 jerk as well.

If one of them breaks, it can lead to jerking when braking, accelerating, or putting the vehicle in gear. Good luck figuring out what is causing your Audi A3 to jerk while accelerating.

It turned out to be the intake plugged with carbon. I had it off, cleaned it out and the head using a large drinking straw duct taped onto the end of a shop vac to suck up the carbon out the head.

After it ran like a rocket for a few days and now its worse than before but different. It idles nice and no smoke. You can hear the turbo whine between 2 - rpm. However, acceleration stinks and it won't rev past rpm driving on flat ground, depending on which gear.

You can hold the pedal to the floor, after rpm it just bags out and won't even rev past the afore said amount. If you are in neutral stopped and try to rev to redline rpm you won't be able to. I have changed the fuel filter and also had it into a shop where they bypassed exhast before the cat and this did not improve much at all. So neither exaust or fuel filter are the problem. I've checked vacuum hoses etc.

Reasons why my Audi A3 has lost acceleration power. No enigine or warning lights!?

I don't have the equipment to read engine codes from computer. The check engine light is not on nor has been. I don't want to have to pay for large diagnostic bill so any ideas would be appreciated.

Problem FixedSeptember 7, — Audi is recalling more than 8, A3 cars after reports the engines can stall. The Audi A3 Cabriolet and sedan engines can experience a knocking condition because of incorrect engine control unit software that can misread the flywheel rotation when starting the engines.

Audi says the car can quickly be restarted and although a stalling condition is dangerous, no crashes or injuries have been attributed to the software. A driver will see a red "Engine Stop While Driving" light if the problem occurs.
