Not 100% sure tbh I think that my increased oil change interval hadn't helped the cooler so I performed a flush of the engine with mineral oil before changing the cooler. All been working fine for 6 weeks now

Morning all Thanks to everyone who provided advice on this topic. For reference to help anyone else who might come across this problem replacing my oil cooler solved the issue. David

Yes the car has a/c i will give that a try. I have also discovered that there is a oil cooler below the filter housing that is recommended to be replaced so could be that? David

Thanks for the advice I did think that a more frequent oil change might make sense i was going to try that over the next 12 months and see if that helps, might even do a 6 month change. David

Hi Keith i used a mutimeter to test the voltage at the sensor to ground. From what I understand this is an on/off switch and not a potentiometer but hapy to be corrected. David

Morning all I am looking for some advice on possible causes of the fault in the header, my 2002 1.9 tdi fabia has occasional low oil pressure warnings it only happens when I have been sat stationary for some time in traffic, so appears to be when then engine is getting warmer then normal. During normal driving conditions I never have the alarm and when I get underway again the alarm goes. I have tested the sensor on the filter housing and that is working correctly so this appears a genuine alarm. I did a major service back in October last year (belts, coolant, etc) and have been changing the oil every two years as I only do 4-5k miles a year in it these days due to work vehicle being my primary mode. Car has done 148k total. Can anyone offer any potential advice on cause? Has anyone had a similar issue before? Thanks David
