Hi there.
'Does anyone have experience with installing a Calix heater in an Audi 80 TDI 1Z?'
gets installed???
I bought a 203 on eBay... of course, I've already read the relevant articles here... (it was a Passat)...

... but I simply can't find a Frost-Sperr cap in the correct position for my car...

... and, of course, there were no instructions included... }
Thank you in advance!
