Golf 118 TSI Engine Failures and Service Campaign 24S4

[Diesel_vert]

Got the car with new Base Engine seems to running for the last 3 days . But today I have new warning on my MFD " Oil Sensor Workshop!"

Any thoughts....

A quick search of the owner's manual would tell you that the vehicle has detected a fault with the oil level sensor, and that you should get a workshop or dealer to sort it out (yet again).

Hopefully, it won't take as long to fix this time round!

Started the car today and no warning now.....

Take it to the dealer anyway. Oil level is not something you want to mess with.

Called the dealer in the morning advise him about the issue. He told me if he warning is not coming it should be OK. Only when I raised my voice and said are you serious thats when he said we will look at it. But he still said we don't know what look for if the warning light is not there.

If the warning light showed up on the dash, there may well be a fault code logged. And if not, at least they should check your oil level, and visually inspect for any leaks / weeping.

Something, somewhere, has obviously triggered the fault - just because it's intermittent doesn't necessarily mean it's fixed.
However, they are right in saying that if the fault hasn't been "saved" (and not all faults are, depending on the level of seriousness) the mechanic or technician can't really solve the issue.

Though it may be highly inconvenient, it would be best to go to the dealer with the fault present & showing, and without turning your engine off - as that acts like a sort of "reset" switch. Once they have diagnosed and confirmed the fault with their diagnostic computer, they can either fix it on the day, or book it in some other day if you or the dealer are busy.

Welcome to the modern era of motoring - good luck, and thank god for warranties!

The vehicle has detected a fault with the oil level sensor. There is nothing to suggest (yet) there is anything wrong with the oil level itself, which he can always check manually using the dipstick until the issue is resolved, irrespective of any malfunction of the actual sensor.

Correct me if I'm wrong, but the OP hasn't suggested that there's anything to indicate a fault in the sensor at this stage. An intermittent warning does not in of itself suggest a faulty sensor, but could equally be related to the car being parked on unlevel ground, for instance. Further, if the car has detected a possible fault with the sensor (eg intermittent signal, voltage fluctuation), it's as likely to throw another error (something that indicates "service me, check fault codes") as it is to illuminate the low oil warning light.

At any rate, I think we're all agreed - get the dealer to check it out, to be sure. No real sense hypothesising.

Correct me if I'm wrong

With pleasure.

I have new warning on my MFD "Oil Sensor Workshop!"

Note that the "OIL SENSOR. WORKSHOP!" message and the "CHECK OIL LEVEL" message are different, and are not necessarily related to each other.

I find it extremely unlikely that something ordinary like not parking on level ground would trigger an actual fault with the sensor. A properly working sensor would just say "oil level is low" or something and that would be the end of it.

Further, if the car has detected a possible fault with the sensor (eg intermittent signal, voltage fluctuation), it's as likely to throw another error (something that indicates "service me, check fault codes") as it is to illuminate the low oil warning light.

Yes, that is correct - although in this case, this fault isn't related to the oil level per se.

Fair call, I hadn't picked up that the message referred to the sensor specifically.

No worries.
I guess one of the pitfalls of anything that involves removing and replacing the innards of any vehicle (engine, gearbox, etc.) is that there's every chance it won't be put back together properly.

Though I suppose it's the lesser of the two evils...
