car seems to have been fine for some time, drove to billing with no power loss problems. drove home from work today, nice hot day air con on everything was fine until, i was sat for 10 mins trying to get out of a juntion. when i finally saw a gap put my foot down and it felt like a 1.1 metro. no power, stock guage was showing what i guess is saftey boost, but she felt like she wasnt boosting at all, come to think of it i would say she was producing a lot less power than an na. got home, switched of engine back on again and boost was back. turned off engine opened bonnet and sounded like the water was boiling, sounded like in the rad then, on more investigation sounded around the front passenger turbo intercooler area. looked a temp guage and it read fine, just above the 9 oclock position. i really dont know what the problem is. ive changed the ecu so cant be that, ive done a diag on the ecu and thats fine, ive fixed the broken electric fan. its been on a conzult, though the idle was too low to do a load test, everything else seemed ok. fixed idle. what can it be now. :rolleyes:

ohh im running optimax petrol also just incase that make any difference and the oil i use is castrol rs 10-60. was told by rac my antifreeze was abit weak but the gueage shows no sign of overheating.

I presume that you had the aircon running whilst you were sat in traffic , this causes the already hot engine to get even hotter 100 degrees plus , its possible that you booted it got det then straight in to safety boost which re-set when you turned the car off and on again .

 

the gurgling(water sound) could well be the AIV's which are positioned behind the wheel arch thats quite easy to sort.

 

the temp gauge stays in the middle from 50-60 degrees all the way up to 110 I think then shoots up that's how crap the gauge is

the gurgling was from the front of the car. ive heard the aiv gurgle before but this sounded as it was coming from the expansion bottle that kinda area.

 

what do i need to do to stop this happening again.

flushed thru the coolant, put rad flush stuff in too. went for a spin and still detting i guess. anything else to do.

was it misfiring? could it be the ptu breaking down due to the heat??

If it's stock and it's detting it's probably the ECU temp sensor.Check the connector, if it's a mess cut it off, put on some suitable spade connectors, try again!
