hi i have a 2004 seat leon cupra 20vt (180) and have a problem with the turbo i think,
let me give you the info that i know and any help would be great.
car is standard apart from pipercross panel filter and forge re-circ dump valve, only done 81000 miles, had it put on dynamics rolling road for power test the other day and it only produced 162 bhp so the bloke disconnected the mass air flow sensor and re-ran and got 176.4 bhp,
thinking this was the problem i got new main dealer part and fitted it, it then seemed to be ok ish but still the whistle from the turbo is nowhere near as loud as it was when i got it.
so today took it for a 30 mile trip and it accelerated through the gears but not pulling very well then when i got into 6th gear with my foot hard down there was a noteable loss in power like the turbo was cutting in and out with a splutter, like i say 81000 still on original turbo and i do like to drive enthusiastically so the turbo gets quite a bit of use. also the big hose at the front of engine was replaced for a new one and is fitted good cos i thought it was loosing pressure from this hose (think this is the turbo or intercooler hose) but not sure. it goes down behind drivers side headlight to inter cooler. i have no smoke at all from exhaust so i aint got a clue. thanks for reading cos i know its a bit long. THANKS
i live in brighton in sussex so is there any people near that i could take it to that know what thay are doing
