Best excuse I have ever seen to get one of these 

TBH, Ive considered it!! lol
Will it affect my car warranty though??
Fooking stealers are useless, take the inlet pipe off ifti and you will need to use some force to push it back into place cos the hose will have a collar inside so it can seat snuggly put the clip back in place then the flexi bit of pipe will stretch so you can get the pipe back into the inlet box(the bit that attaches to the slam panel...that pipe is not broke let your dealer know they stink and call VW customer service and tell them that this dealer tried to rip you off

ps I dont own a GTI but can see that pipe is fine. it is a similar setup on the GTtdi but my inlet hose isn't shaped like that.
Exactly what I thought. I did give it a try but its bloody hard to push the hose back up into place because of the collar. I just about got my mole wrench around the clip to open it a little, but the tool isnt the right size and flips off suddenly!Maybe I should try it after a drive when everything is warm and a little more flexible??
I rang VW Customer services today, and they said they tend to side with the retailer!!! They said I should go to another dealer and get a second opinion. If the other dealer states that it is a warranty job, and fixes it quickly (as expected!) I should ring Customer Services back and lodge a complaint fo rthem to deal with.
I may pop in to another dealer on Saturday - this dealer also fixed my mates GTI whose hose also had come off!
I had EXACTLY the same problem a few weeks ago, after the dealers serviced the car. Like you, I couldn't manage to loosen the clip and refit myself, no pliers big enough!
So I called into the dealers, and it was a 30-second job! A mechanic just opened the spring-loaded clip with a large pliers, pushed the pipe in further, so it would grip more firmly, and re-attached the clip. Simple. It's been fine since.
The dealer who told you something is "broken" is talking crap.
I even asked him what was broken, and he said the hose itself!!!
I asked him where, and he waffled around it and gave me no answer. I then asked how much to replace, and he couldnt even give me a price! He just said he would contact the dealer the car came from and see what they said, and get back to me!
Hasnt got back to me since!!!
I contacted the guy I bought the car from (he has a private dealership for prestige cars) and he said he would chase up his contact in the VW dealership where he bought the car and see what he says. Guess thats good of him to do since he could just turn around and say its not his problem I guess!
This has been a complete shambles from the start - and all for a 30 second job!!!
