Polo gti check engine light *urgent*

[JJay]

Hello i was driving tonight and on my way home, check engine light came on about 4 minutes later the oil temp gauge dropped nuts and was sitting at about 50 rather then the usual 90. What could this be???? I think from what i know, it could possibly need a new o2 Sensor? If anyone knows anymore please help urgently. Thank you.

You need to get the car scanned for codes.

Which Polo? Needs scanning anyway.

I assume you mean engine coolant temperature not oil temperature.

It will have nothing to do with an O2 sensor - check your coolant level, and as above get the car scanned for fault codes.
It could be a simple coolant temperature sensor failure.
