Advice wanted on 2008 leon k1 keeps throwing throttle body fault

Hi,
I'm all new to this and recently bought myself a 360bhp stage 2+ k1, (never owned a leon before)I got it home to have the traction control light, tyre pressure and epc lights on, after having diagnostics on it, the throttle body was replaced only for the same faults to pop up 2 days later, the diagnostics are pointing at the throttle body again, has anyone else had the same problem? Could it be something to do with the remap or possible ecu problem, any advice appreciated.

Thanks

Mandy

I can't remember what the codes were but the 2 that came up were regarding the throttle body even tho I had a brand new one fitted last week the garage is now saying it could be a software or ecu problem.

Yeah that's one of the same codes James, I've been on the garage today and they are thinking wiring loom, I don't know what spark plugs are in mine but it had all new last week with it's service, I feel like banging my head against a wall with it, did you get an electrical specialist to check the wiring James, I had thought about getting mine checked but wouldn't think they would find the fault unless it faults while testing, I can have the codes reset and it drive perfect for a couple of days, all I see is money through a shredder lol

Mine did the same I bought it then I was away for a week and they had gone off when I got back I'm glad I'm not the only one with the problem but mine does it even if just idling and I think I had Bosch plugs put in so can't be that :-( guess the car just hates me or the seller saw me coming lol

Could the speed sensor cause this fault?

Lol well I bought it like this I'm kinda hoping it's not the ecu as it will wipe the remap but I'm open to all options so I can actually drive the car, so annoying having it as an ornament :-(

Yeah had the car reset yesterday drove it less than 5 miles home left it all night then faults were there again this morning, it's off for a throttle body pedal thing fitted to see if that's the problem if not will be having a new wiring loom and if that fails then new ecu and if none of that works I'm scrapping it lol
