Hi just wondering if anyone could help I was driving my car the other day (audi a3 07 2 litre diesel) and went into limp mode but didn't get no check engine light or anything restarted car and went away but the car feels alot less powerful and also more noisy like air suction nosies after getting home I plugged in my code reader and it showed a p0299 turbo underboost I've taken it to the garage and they've told me I kneed a new turbo however ime just wondering y is the engine light not coming on do u rekon it does kneed a whole new turbo or couldn't be so thing else don't know if the garage just saying kneeds whole new turbo cus they don't want to mess round with it.
