Hi Mr. Siena, you're doing a wonderful job first by creating this thread and also by taking out time to reply every single query. May God bless you Sir.

I need help with my sister's car. Below are the details.

Make: Audi.
Model: A4 2.0
Year: 2002
Engine: 2.0 FSI, 4plugs inline.
Transmission: triptronic 5speed automatic
Front wheel drive
Europe.

Issues:
1. Knocking of rear of car over bumps and rough roads.
2. Car has excessive bounce generally on rough roads/bumps.
3. Clicking noise from front wheel when turning corners.
4. Aircon doesn't blow warm air, neither does it cool.
5. Airbag warning light on.
6. Remote key doesn't work
7. Central lock doesn't work
8. Electric window doesn't work
9. Horn doesn't work
10. Fuel gauge doesn't work.

So far the mechanic said the following items are bad and need replacement parts.
-Front suspension (pair)
-wheel shaft.
-Shock Absorb (front and rear) *Damper.
-Airbag switch.
-He also said the aircon only needs a gas refill.

Pls sir, what do you think about all these and what would you suggest that I do?
As always, Thanks boss.
