Lexsus is200 electrical burning smell and steam coming from engine

SOURCE: engine maintainance light on

do you mean the service light or the mil (engine management light? ) you can get a obd2 code reader if its the mil light but be sure to get one that is for VAG codes, if its a vw or one the reads eobd and *** codes for lexus (ebay from £23 )
if its a service light you need not worry too much but you can also get the service reset tool on line

SOURCE: golf 1.6 diesel engine, electrical burning smell

please state year as i will need to know if tis a common rail or injector pump type of engine ,if it common rail then loose the silly plastic cover on top of the engine as if it is what i suspect then this cover is making engine hot and the coils on the injectors are overheating ,also i think no 4 injector has the sensor on it that times all the others in and this could be the one thats faulty,these injectors are expensive and the lead one is about 500 euros

You could possibly have air in your cooling system. If the dash gauge temperature sensor does not have coolant flowing past it, it will give a false temperature reading while your engine is actually overheating. If you recently drained and refilled your cooling system, you might need to bleed the air out of that system. If you didn't drain it recently, you might have a leak that's letting out coolant and letting in air.

P0171 is a "System too lean - Bank 1" code.


Pretty much means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust).

You might not notice drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.

Causes:

• The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
• There could be a vacuum leak downstream of the MAF sensor.

• In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
• Inspect all vacuum and PCV hoses, replace if necessary
• Check for a dirty fuel filter and proper fuel pressure
