Have people had problems with chips? Turbo failure etc...

NoFHoes

Yes and no and maybe

Chips increase how hard the engine and turbo work but there is no direct tie between a chip alone blowing a turbo. Many causes for turbo failure can go as far leaky hoses, bad bpv's, improper oil levels/quality/oil change intervals, other malfunctioning parts that are not fixed, improper warmup/cooldown (oil pressure issues on startup and sludging of oil on turbo spindle and mechanisms if ample time is not given to cooldown) etc. Or simply you had a turbo go bad or old version.

The S4 was designed to be driven hard but adding a chip can increase the chance of something going wrong. If you are a light foot and drive spiritedly very occasionally then chipping may not give you problems if you maintain the car during normal intervals and prevent boost leaks.

Try the chip/turbo survey and judge for yourself...<ul><li><a href="http://audiport.com">Sruveys</a></li></ul>
