Thermostat housing O-ring

[SoloTSi97]

Sorry to revive an old thread but any idea if there's a solution to this? The seal in my housing is shot and no longer seals against the thermostat. Turns out, that's probably been the cause of my "implausible temperature" codes for a while now. But, the housing itself is NLA ... dealer confirmed that there are zero in the US & zero in Germany. Of course, I can source a used one but that's going to be a bit of a gamble (that's only going to get worse as these cars continue to age).

Any chance some enterprising soul in the aftermarket has come up with a viable solution here?

How many miles has your car done?

Mine has done 180k miles on the original thermostat housing. Perhaps yours got damaged or had a manufacturing defect.

149k on the clock here. I don't think it's a common failure point (yet) but it stands to reason a seal could over time degrade I guess. I'm not sure the history of mine but it pretty clearly doesn't seal fully against the thermostat housing.

I had one on order for months and cancelled it in the end.

It's probably worth getting a secondhand one just to confirm it fixes the fault, with a view to getting a new one at a later date.

Yeah, my local parts guy said he saw zero in the US and zero in Germany. I'm not sure if there will be more at a later date or not.

So yeah, I think the hunt for a good used one begins!

"Back order with no ETA" i was told by the parts department. So unless we order 10 each there will be none made.
