The first problem i have is, when you check the level of oil in the engine its accurate but when you drive for a while a warning sign comes up REDUCE OIL LEVEL. The mistery is, when the engine cools down the oil will be accurate. The second prooblem is,my car was parked for about12days and befor now i seldom drive the car.UNDERVOLTAGE CONSUMER DEFECTIVE come up on the dash so i did not drive the car and i noticed the a/c was not blowing as it should.The next day the battery was down and so i took the battery to the garage for charging after which i put it back on, same problem.
I had the same "undervoltage, switch consumers off" message the last couple of days. Then today, another warning in red appeared "battery/alternator, see service". This was a bad sign. Luckily my car didn't stop dead in the middle of the road on the way to the shop. The service guy said the alternator was bad. p.s. my battery went completely dead about 4 months ago----this was an early warning that the alternator was going bad, but instead I just got a new battery.
Regarding the first problem, there is possibly an oil level sensor issue or vehicle version coding issue(both can be more fully checked at a dealership). The second problem is not uncommon. Obviously, there could be a low voltage if the vehicle sits for a long time or is not driven alot. Sounds like the ac system lost synchronization due to lack of voltage. With vehicle running, you should be able to press and hold recirc/rest or recirc/defrost buttons on ac control panel(can't quite remember which combination). Press and hold until leds start flashing, then the ac system will go through a resynch phase. If it completes this and the led's stop flashing, then it's ok. If it does not and the led's flash very quickly, this indicates an actual malfunction of ac system adjustment motors.

An effect of low oil level may damage valve lifters, they may have experienced excessive wear. Definitively, continuous running of motor with low pressure might damage the motor. If you check always oil level and it is an ocasional event, as long as the engine wasn't starving for oil under load (i.e. the oil pressure warning light did not come on), it won't have suffered immediate, catastrophic damage I would worry more about the cumulative effect of chronic neglect. After the car is fully warmed up and warning light come on at idle your engine is on its last legs.
Yes its mentioned correct in manual.The HI indication comes on when there is about 1 quart too much oil. Get the excess oil drained.-----------CHECKING ENGINE OIL LEVEL:-------- A sensor in the oil pan allows oil level to be checked without opening the hood. It provides an accurate measurement of oil level, whereas the low engine oil level indicator warns that oil level is definitely too low. With the vehicle parked on a level surface, the engine is warmed up and shut off for approximately five minutes.When the ignition switch is turned to the ON/RUN position, an ISO oil level icon appears in the trip odometer window and a "clock" icon in the cumulative odometer display. Pressing the knob to the left of the speedometer twice within one second displays one of the following messages: • OK • -1.0 Q (-1.0L) • -1.5 Q (-1.5L) • -2.0 Q (-2.0L) • HI The indicated amount of oil must be added to the engine if the message -2.0 Q (-2.0L) blinks and a signal sounds. The HI message indicates that the excess oil must be removed from the pan to avoid possible engine or catalytic converter damage. If the ISO oil level icon and "clock" icon remain on when attempting to check oil level and no message follows, or if the low engine oil level warning lamp comes on, a malfunction in the engine oil level system is indicated. A conveniently located dipstick allows manual checking of the oil level. If no leaks are noted, continue to drive to the nearest service station where the engine oil should be topped to the "full" mark on the dipstick with an approved oil.--------------------
First, check your engine oil level , while on level ground, add if it's low. (The oil viscosity should be labeled on the oil filler cap) Blue smoke is a sign of burning oil, not a good sign. White smoke is a sign of coolant mixing with your engine oil, a worse sign.
Your computer is telling you to check your oil, so do it, or get it done.
If your oil is low, top it off and keep checking it regularly to see if your engine is consuming it. If it is, I would recommend getting it looked at for either a leak, or low compression. (Worn out piston rings will cause oil consumption and poor performance.)
Hello. All of the warning lights are activated by a sensor. In this case since the engine oil level checks out fine the cause of the engine oil warning light is a bad sensor. You should be under full warranty. Have the dealership change the sensor. Joe
The oil pressure switch is located on the oil filter flange for both gas and diesel engines. Incorrect oil viscosity can influence engine oil pressure. Before performing repairs, ensure that the engine has sufficient quantity of fresh oil and correct viscosity. Always check level when the engine has fully warmed up (after radiator cooling fan has operated) then check your dip stick. During high speed turning the oil in the pan sloshes to one side and starving the oil pump causing a warning indication. So check it after it has pressurized the system to get accurate reading. To much oil can cause 02 sensor malfunction so don't over fill.
When you say the oil level is fine, has it dropped at all in oil level even within the fine area?
Your oil sensor may faulty, or you may have a pressure leak somewhere since you said it occurs when you slow down (let your foot off the gas which will reduce the pressure). One known issue with golfs (hope it's not with yours) is that the rear engine seal often springs a leak and ends up leaking into the flywheel and transmission assembly.
low pressure in the tranny, did you check the oil level in park? if so you might have to check it in gear with someone holding it on the brakes, then re-check... hopefully it isn;t the pressure solenoid.... $$$$$$.... they can be expensive, cheers!
