Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

The pressure ratios in the intake system are changed by the optimized induction system on X51 (and Tiptronic ) so this is needed yo keep the ratios balanced.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Gents, Could anyone tell me please what this hose attached to the throtle intake tube(from the airbox) is for/what its function? Its my friend's 40th Anniv. So question #2 is it just on 40th Anniv cars or X51 engined cars? It wasn't on my ex-996(MY02). Trying to help him. Thanks!

POST 2Original post

I have that on my 02 C4S as well, asked that question once, didn't get a sure answer. I think it's some kind of return hose for gas/exhaust/combustion vapors or something.

POST 3Original post

Is it a tip?

I don't have the hose, but if it's on the 40th anniv, then it's not for a tip. I have an '03.

POST 5Original post

Mike, It's a breather line found on all X51s and Tips. Not exactly sure why it's there. Some say it's just an equalizer line. It does have a fair amount of suction though. Hope that helps.

POST 6 / ORIGINAL POSTEROriginal post

Thanks Gents! Car is not a tip. Its a 40th Anniv Edition which has an X51 on it. I hope its just a return hose for exhaust/combustion(EPA), then it wont be a problem for what he's(my friend) is trying to do.

POST 7Original post

It goes to the "sucking jet pump" on X51 and Tiptronic cars. The pressure ratios in the intake system are changed by the optimized induction system on X51 (and Tiptronic ) so this is needed yo keep the ratios balanced.

POST 8Original post

What he ^ said!!! Just for the record, I didn't have a clue what that hose was for (other than it directed air some where) prior to Loren's post. Nice Loren, as usual. BTW, is it true that your last name really is "All-Things-Porsche" or is that just a rumor?
