Winter cupra r problems. Advice please :)

[Elliottbrophy]

Hi all,

I bought a leon cupra r in July and think I am having some normal winter problems. I'm getting water inside on my windows and steamy windows a lot. I also have had a fault code regarding my thermostat or temperature sensor. Could any advise how to fix these problems please?

Thanks!

check for damp carpets... usually door seals.
whats the code... does the car stay at 90 on the gauge or drop back?

Cheers mate! I think it could possibly be the pollen filter. It keeps dropping Yhh and then goes back up

Thermostat needs a change. Hopefully its a pollen filter issue... should just be wet passenger side?

How does the thermostat throw up a code when it's completely manual with no electrical connectors etc?
My can ran terrible when the temp Sender went. Only buy genuine as the patten one I tried only lasted a few months before packing up.

It is wet just passenger side and I have changed it recently. I'll have a look at that. No idea but I scanned my engine for codes and that's what it said. Where can you get genuine ones from?

I think that's the code I got when my temp sender failed. I would start there as its much easer to replace than the thermostat. Any dealer should have them I paid about £32. Cheaper on eBay http://m.ebay.co.uk/itm/201192881693?nav=SEARCH

Not sure but the behaviour of his gauge points to thermostat.
Usually more poor running as you describe when its the sender

the thermostat doesn't have any electrical connections no. but when the car doesn't reach operating temperature when it should the coolant temp sensor obviously picks up on this and the ECU throws a fault code

I had that code a few months back. It was a faulty Coolant Temperature Sensor. Make sure you get the green one.

I too also have the in-car swimming pool in the footwell.

To be honest you might aswell change both the temp sensor and thermostat. Neither are expensive and it will ensure you have no trouble of these parts for a while to come!

On my last car I had windows steaming up when the heating was put on and it turned out to be the heater matrix

Hopefully that's not the case for you!

 

[Elliottbrophy]

I think mine might be the pollen filter leak. Has anyone got any links on how to change the thermostat and the temp sensor as well? And links for genuine parts

If water runs off the sill when you open the door after its rained, the problem is the door seals and this probably accounts for 90% of wet carpets. The pollen filter seal is massively over-diagnosed.
