i would say have your abs system bled. this only requires a computer and someone who knows how to use it. after bleeding the abs then the rest of the system should be bled. if you had a bad secer it would set what is known as a hard code and the light would always stay on.
Check the pcv hose from the intake manifold to pipe with the car running. They get soft with age and will collapse while the engine is running. Just fixed my 2004 for this problem. Remove battery cable for a few minutes to reset ecm. Also a loose fuel cap will turn light on also.
it could be that the wiring to or from the knock sensor has a prob. also after the knock sensor was changed was the code cleared? if it was not it may be a inactive code that stays in the computer causing the light to stay on...
It means that the pre heat is in operation.It is a system that burns diesel to create heat to warm up engine quicker so that warm air comes into car sooner.The smoke is the exhaust gasses from the system and normally the whistleing and smoke stops when engine reaches running temperature or on short journeys approx 1 minute after engine is turned off
During summer when no heat is required and air con is on cooling it should not light even when starting from cold
you must reset the oil life . WITHOUT STARTING THE ENGINE, put ignition in the ON position with the dash lights on. NOW this MUST be done within 10 seconds. Push the gas pedal all the way down to the floor and release 3X. This should clear the light. Sometimes necessary to repeat if not done in a timely manner.
oil pan and sump damage are very likely to lead to oil distribution problems, this is not temporary, if you hear a knock have it checked by a local mechanic who can verify it for you, it is possible that the engine is damaged internally.
could be a bent valve but all depends how much da car means to you if you want to keep your car bring to a local garage or specialest ask them or bring it to a place where dat modify cars and ask them how much dont always go on 1 garage quote shop around and pull a fella in a garage to the side and ask em would he do u a favour as an nixer to do the job and see want he says come bak to me if notin happens
so all the lights that come on when you first turn the key on stay on? maybe your alternator is not working properly? or not connecting to your dash panel correctly? or maybe the engine management system has a fault in it? more likely to be a dodgy connection to your dash board.
