Whats this in the engine bay?

[hipcity 10]

Hi all

 

After a week of not driving my 2.0 16v corrado - the battery went dead.

 

I had to charge the battery for a at least 4 days and by continually turning the key - got the engine to start.

 

Anyway - a long story short - once the engine started - it sounded like a tractor and puffs of smoke started to come out of the following in the picture for about 5 to 10 minutes???

 

4 days later the car starts find every time and sounds fine wit hno smoke.

 

Any ideas what the part in the picture is as it looks broken??

 

Thanks

Not broken. Where the garage can connect up to analyse exhaust gas (CO level),

Thanks for the reply - I was worried there thinking it would need fixed

looks like the piece on the end has broken off though,which accounted for the black soot all over the bay.go to a scrappy and grab one off another vw.their common item and its just a small piece of plastic/silicon.Or weld/bend it shut.I have never seen a garage use this for diagnoistics like its designed for.

As above- you just need a new rubber bung. Happened on one of my old valvers too- sounds hilarious!
