Tq boss replying all my threads.
How to overcome this?
Follow schedule maintenance enough?

first , bring competent mechanic to check the car thoroughly
then put aside some good money to restore whatever that need to be fixed

diesel engine maintenance a bit difference from petrol car , and it is not meant for short journey-in other word, you gotta thrash it

you go test drive first the car lah, sometimes it does looks good, but when it comes to driving it , well, can tell u the whole different thing also

good luck
