Basicly i have an audi a3 1.8t s and have had it remapped with revo software from 150 to 207bhp
tonight i was driving with 3 heavy passengers and stuck it into 3rd gear and gave good ammount of gas to pass someone.
then my engine management light started to flash and my car was juddering shaking when turbo goes on.
now i can drive it ok, but as soon as i give it any decent power the engine management light starts to flash then goes off,and the car judders a bit like something holding it back,it will still go upto 80mph but only on a long strech without the turbo,in low speeds works fine if slowly. the turbo just isnt wanting to work at all now.
any ideas would be so greatly aprechiated.
thanks

 

Have your REVO programer revert it back to stock and see if you are still having the problem with turbo.

 

i guess its not the revo mate as it was working fine just only screwed up when gave too much power with people in, my dad is mechanic and told me it sounded like gone in limp mode, designed to get you home, maybe i just need to remove this limp mode.

 

Yeah, it sounded like limp mode, but if you turn off the car and restart it then that should clear the limp mode. If it is continuing to be thrown into limp mode then there is something else at play.

 

there was no smoke, or loud bangings, so i guess its not the turbo blown up.

 

If the turbo was blown up then most likely you wouldn't be able to drive the car. Turbos usually break causing oil, and maybe coolant, to be sucked into the intake seizing, and sometimes permanently destroying your engine. It's very very ugly. My guess is there is boost issue somewhere and the car is not producing, or over-producing, the requested boost and then the ECU sends you to limp. You need to get the car looked over by a qualified person.

 

ok i got the errors mate
po411 secondary injection air system faulty flow
p1602 power supply low voltage
po300 16684 misfire recognised
po304 cylinder 4 missfire
po571 back light switch

 

Well, I'm not a mechanic, only a tuner junkie looking for his next fix. It seems to me that you have a couple issues. You need to look at replacing the plugs/coil packs for the faulty cylinders, or I would suggest replacing them all. Then you also have an air flow problem. Not sure if you have a leak somewhere, faulty MAF, or some other issue? Maybe Dave can chime in and you can get a professional's advice.

Cheers!

 

crazy i fixed totally with changing spark plugs to platinum ngk

 

Congrats! Cheap and easy fix.
