Need help!
I bought a cupra tdi as a standard car, it ran faultlessly till I have it remapped, few weeks after the map and it would randomly not boost, and then after a mile or so of driving it would start boosting again, it kept doing this but the length of time it was not boosting for got longer until it just refused to boost at all.
I put this down to the turbo going, so replaced it with a gtb2260, with supporting mods, I knew it wouldn't run very well until I had it remapped again, but it's still doing the same, turn the car on and it won't boost, if I knock the car off while at speed and then bump start it, it then boosts fine until I turn it back off, I think it's just a bad map but not 100% and was wondering if anyone know what else it could be? Don't want this turbo to go bang as the set up cost me a small fortune.
TIA
