Bro, very sorry to hear that. What I normally does is I'll get a workshop manual every time I bought a car either new or otherwise. This will help me in determining whether the info by the mechanics are valid or otherwise. Some of these people ingat kita ni banyak duit and they will swindle us like hell. Get a second opinion or usually talk to some other mechanics and learn their views. Buy your own parts and this can very much reduce your pocket hole. I've been buying parts since 1978 until today. What I was told that the petrol pump in the model cannot be hung dry, meaning to say the petrol must always above half tank as the pump will be totally immerse in petrol. On the other hand, the baterry is a 100Ah one and it cost around 500 to 650 RM. The ESP sensor breakdown can be curtailed by having fluid change every 20k kilometers as to avoid water build up in the system.Before firing the car, switch it on until the ESP light go of and when the warning light turn on, let a few second pass before firing. This will help a stable current in the whole system and a fully working pump. Be gentle with the keyless key as it is a little complicated. After driving long distance at high speed, let it idle before switching off. These are some precautions to avoid premature wear and tere. There are others too but no harm try. Hopefully this can help to reduce some bills or making deeper holes in the pocket. He.. he.
