Have a bmw318 x reg 90,000 miles eml light on constantly after having 02 sensor changed as was code shown. garage done extensive work hoses etc in case of leaks but still cant get light off. why ?

on the 98 toyota camry check that the gas cap is on tight or look at my fix on the toyota sienna that could be it or a vacumm hose could be split or leaking i would have these checked before you get into very expensive repairs look for the obvious first

There is not a lot due at 60,000 miles as far as regular maintenance. Depending on which engine you have, a timing belt replacement is due at 90,000 miles. (The 2.4L engine is chain-driven) Spark plug replacements are not due until 80,000 miles.

In the meantime, I would have the condition of the engine coolant checked. It should be checked for the freeze protection level as well as the acidity level. Chemical test strips are available at your local parts store for this purpose.

All fluids should be checked for proper levels inlcluding differentials and transfer cases if it is a 4X4. Check and fix any fluid leaks right away. Fluid leaks can lead to rapid deterioration of rubber mounts and hoses as well as damage wiring harnesses and computer sensors.

If the battery is original it should probably be replaced due to the age of the vehicle. If it is not original I would have it tested. Remember NOTHING works on your vehicle without the battery.

Should be take it by auto zone have them check for codes . It is free in most states.

Take it back

Carfixer 1 is right. The Hyundai engine is called an interference engine, which means that when the timing belt breaks, it will allow the valves to hit the pistons and you will ruin your engine.

Do yourself a favor and replace the belt at recommended intervals. If you are past the 60k mark, have it done right away and save yourself a lot of grief and expense.

Top hose hot and bottom clod??? Change your thermostat ASAP.

You need to have the cam belt & water pump replaced at 110,000 miles not 90,000. You should have the transmission fluid changed, brakes & all hoses inspected. The coolant should be drained, thermostat replaced and fresh coolant installed. Of course the air & cabin filter should be replaced every 30,000 miles. The fuel filter is permanent and needs no replacing. Brake fluid should be changed unless you have already had this done. Serpentine belt replaced at 110,000 miles with the cam belt.

Basically the mechanic will make sure don't need a tune up. or have vacuum issues or leakes in the exhaust before the cat. Then he should check the front 02 sensor to make sure its not getting lazy. If all this passes then you will need a new cat. If the O2 sensor has more than 70,000 miles on it it needs to be replaced anyways so you may just want to do this first and hope the light stays off.. The problem with a lean code is you will wear out the cat real fast if you didnt deal with this and kept driving the car. The lean code could have been vacuum leak or a bad MAF sensor or weak fuel pump.

Hi, Since you have both codes Fuel system lean and MAF low I would bet money on that you have an intake air leak after the throttle. Check all hoses connected to the intake manifold, gaskets, injectors are put in place etc.

Hello There

The EML stands for Engine Management Light . eml only comes on in BMW's when there is a serious problem with the engine. I'd suggest going to mecanic and have them read the code which will tell you what the problem is.

Hope This helps
