I have a skoda fabia vrs 2011 it is high mileage at 145,000 but well taken care of full service history car drives mint with no issues but recently when the oil temperature gets above 80° degrees the car stalls and shows the battery light on the dash when I let the engine cool down and drive it drives with no issues this only happend 2 or 3 times but was just wondering what could be the issue ? Thanks 

Sounds like a stuck thermostat or similar but I have no actual experience of the VRS... At that age and mileage, though, replacing a thermostat is not a big issue, I would have expected to do it.

 

This IS just a guess and hopefully someone will come along with real knowledge of this variant and either offer a better likelihood or back up my guess. Thermostats are usually quite a cheap, simple replacement part on cars so even testing them is often pointless. If it works with a new one, bin the old one but no improvement, store it away!

Thanks will try it 

Welcome.

Not so sure on the thermostat since you say when the Oil temp gets above 80*oC, not the Coolant temp which gets to 90*oC much sooner.

What is the coolant showing on the gauge>

?

So how do you get the Oil to cool down, it needs to get up to around 90*oC, which might be taking 10 miles or more.

It takes a long time for the oil to cool, and then it starts rising again to at least 92*oC & higher.

 

You need the Fault codes if any read.

 

?

What has it had in the way of servicing?

Just Oil, Filters, Spark Plugs? & Service Campaign on the DSG '34F7'.

 

The Water Pump / Supercharger Magnetic Clutch might need replaced if not already done. 

That and the 2 rubber belts.  This costs around £450-£500 when needed. 

A main dealer might want an hours diagnostics on top of that, but that is just a rip off if the job is to be done.

I get the point of the oil temp but by nature of the oil getting warm, the engine is warming up and so, naturally, so should the water temp. 

I did say though, I have no knowledge of the VRS so I could be blowing smoke up your exhaust! it was just a consideration and a fairly inexpensive one to approach.

The Twinchargers can have the coolant indicating 90*oC in just a few minutes / miles of starting and setting off.

It can take 5 miles or more at 60 mph to get 50*oC indicated Oil temp,

and at low ambient temps, 15-20 miles to have the oil show between 80 & 90*oC.

 

There are lots of sensors and connectors,

and the connectors for the water pump and the ECU are prone to water ingress and corrosion.

Thanks. You have a much greater understanding of this vehicle so hopefully, you have given the op greater guidance. 

This is why this forum is so great. 

My little old diesel 1.4 takes two weeks to warm up!
