This one:

By the way, how can one check if the problem is really from the thermostat housing ?

Can you please tell me what pin you're talking about and how i can see if it is really broken?

Thanks

I’ll try to get some pics to show you tomorrow

The 12,13,14 and 15 from the picture you posted are brand new original parts.

Are you talking about the big thing with pipes?

Yes the big thing with the pipes

Thank you for the time, i really appreciate!

HI,

I'm having a big trouble finding the thermostat housing, they say they don't make it anymore since 2015.

Where can i find one? Part number is: 032 121 111 AB

Hope you can assist me on this.

Thank you very much

One on ebay here

Other than that, youll likely have to phone your local VW dealer to see if there are any in the dealer network sat on a shelf

its a somewhat rare part. A dealer in germany may have some old stock

Is yours an AJV engine code?

Thanks!

Yes it is AJV and that first photo is not correct, mine has 3 tubes in the back, 1 left side and 2 right side (if you look at the engine from the front of the car).

I already got one from a local dealer, it's not an original part as VW says that this part was discontinued in 2015.

I phoned a couple of official stores, even classic and heritage parts, neither have the original part in stock.

Besides the original part costs around 208 euros in europe with vat. This one i got for nearly 40.

That is the biggest problem on these cars, thermostat keeps breaking after 3 or 4 years.

At least you managed to get one

Thermostats should last much longer than that. Genuine ones should last at least 10 years if not longer

Part number is 032 121 111 AB.

Thanks again
