lov mk6 but....

[Racinrick]

I have had my new GTI MK6 for 3 weeks and like it (had Volvo 30 before it). But am having a problem with the rear window washer leaking on the back glass...frequently. Has anyone had this problem...goes to dealer on 7/12 for a fix, I hope. Also planning on taking off the 18" Detroits (they just look weird). The manual says use 91 octane fuel, is this mandatory?

[kiserhd]

91 octane is required.

I use only 98 octane fule and some time the 100 octani Vpower Shell.

Octane ratings in europe are different, but 98 in europe > 91 in the US.

[BIGGREEK]

yea europe uses the RON system (research octane number), versus us here in the state, we use AKI method (Anti-knock index). Its just a different way the companies measure fuel burn resistance. So super for Europe would be like 98 RON which translates to 93-94 Octane.

yes, i recently bought my 2010 GTI and i have the same problem...i guess this is a manufacturers defect. i had mine for 2 weeks(just hit 1500 miles)

There is a TSB for the washer fluid leak. A check valve is to be installed.

On the rear window thing...took it to the dealer, they ordered a part (Ckeck Valve?) and went back later and they installed it. Still wees down the back window as before, so I put painters tape over it and now fixed!!!! The rest of the car I really like, just waiting for it to cool down so I can get on the track.

So that's where those stains are coming from. I thought maybe it was rain or carwash water dripping from the spoiler? I didn't know the car even had a rear window washer?

[nitroscope8]

turn key on and press washer/wiper stalk FORWARD. ya, that checkvalve seems to be hit or miss with some people apparently.

[tibimakai]

this valve it's not a one way valve? maybe they installed it backwards? or is a pressure valve? maybe they need to install two of them? just some thoughts, not an expert

[nitroscope8]

It's called a non return valve. I think it works similar to a diode adn isn't strictly a one way valve...or else it would not work at all lol.

I am looking at getting a 2011 GTI. Is this still an issue or has it been fixed? I am wondering if this is something I need to have the dealer do as part of the purchase.

[nitroscope8]

It was hit or miss with the 2010's .I can't say for sure if the problem has a permanent fix for production but not too many people are coming in complaining about it.

OK, excellent. This is good to know. Hopefully if things work out I will have a new GTI sitting in the driveway within the next month or so...
