wondered if anyone is able to shed some light, Need to see my options an what to do..
I brought the S4 last weekend, its been remaped, full exhaust, etc an loads of work has been done, cambelt, egt sensor. The engine seemed faultless, no noises, nothing. it run lovely and i had no doubt about it. been driving it all week, owned turbo cars before so always warm and cool the turbo's etc. Took it for a little drive this saturday, seemed fine as usual, put my foot down in second, soon as the second turbo kicked in it popped and lost all power, and now it wont run. it starts and you can keep it going by revving it to stop it stalling, but its gutless and has a bit of black smoke, plus stinks of fuel like its over fueling. and you can hear turbo noise so at least one turbo is spooling up.
I plugged my vagcom into it and its flashed up every fault code relating to sensors on the exhaust and inlet. o2 sensors not active, egt sensors, maf sensor. these are fresh codes too as i tried the vagcom on it thursday to make sure everything was good, and there was no fault codes what so ever.
All i can think of is turbo? whats your views? I would like to know 100% before spending out a lot of money replacing them.
Ive been looking into ko4 upgrade, cheapest ive found is 4k. is this avarage price or is there a cheaper way? Also how much are new ko3 turbos and where from?
Is it defiantly a engine out job too?
Massive thanks in advance, i know nothing about these cars so could do with some help on where i stand and what my best option is. also how much would i get back in parts if i broke the car? roughly.
