Wayne2015 10 Posted May 22, 2015 yea its the mk4 one, you have to ovalize the 2 mounting holes slighty with a small round file or drill bit? as the hole centers are abit bigger then the rados {5mm?} but its easy to do , its deffo a worth while mod or you could just buy a rado vr6 tank and cap and straight swap , either way idd get a new tank and cap as it does make a huge difference, heres a syringe you can get to suck out coolant, you can also use it to suck power steering fluid or brake/clutch fluid just clean it out straight away http://www.ebay.co.uk/itm/Large-Big-Huge-50ml-100ml-160ml-SYRINGES-INK-CISS-IPA-GLUE-DIY-FAST-CHEAPEST-/151120286550?pt=LH_DefaultDomain_3&var=&hash=item232f789356 Cool I ll keep note of that Silly question. But why is it a better upgrade to the C one? Quote Share this post Link to post Share on other sites
VW_OwneR_85 1 Posted May 22, 2015 because both tank and cap are cheaper and readily available and will be for ages, other then that theres no real advantage to them, the mk4 electrical plug also fits in nicely with my engine as its mk4 2.8 so has the same style plugs , little things add up :) Quote Share this post Link to post Share on other sites

Hairyarse 10 Posted May 27, 2015 Wayne you're a proper mechanic now I reckon ;) Maybe just 'servicing' the sunroof will help reduce/stop the leak? That silicon grease is good stuff - very sticky though!! If you put a lot on then be prepared for it squirting out everywhere! lol Quote Share this post Link to post Share on other sites

Not brave enough to deliberatly leak my car! :lol: but your brave enough to remove the sunroof ;) your leak is an odd one! but i think if you get some one with a hose pipe on it whilst your in the car looking for it the leak will become clear, good luck!

Lol Cheers bud! If i use a hose pipe it will produce the another leak! :( :shocked!: It is a bizzare one, as the third leak i understand. But not the leak from near the drain outlets ??? :bonk: :shrug: Quote Share this post Link to post Share on other sites
VW_OwneR_85 1 Posted May 27, 2015 lol dont use the hose full bore on it! just enough so its got a nice steady flow into the center of the sun roof, or point it straight up full bore for rain effect haha Quote Share this post Link to post Share on other sites
Wayne2015 10 Posted May 27, 2015 lol dont use the hose full bore on it! just enough so its got a nice steady flow into the center of the sun roof, or point it straight up full bore for rain effect haha Lol I use a slow steady hose pipe flow to rinse car (after wash) and it trickled into middle back of sunroof (between sunroof inner headliner and outsr sunroof headliner). I think the reason is my outside sunroof seal shrunk - so letting more water in than usual. So that i understand. But the leak that wets my driver seat and rear seat??? As all drains clear All drain outlet clear All drain channels clear No blockages (as tested when i took sunroof off) So a funny one :bonk: :shrug: Quote Share this post Link to post Share on other sites
Wayne2015 10 Posted May 27, 2015 (edited) Do love the beading of freshly waxed paintwork ... :) Even if it JUST the sunroof panel! :lol: ;) :dance: Edited May 27, 2015 by Wayne2015 Quote Share this post Link to post Share on other sites

Glad that's not the case and you may have accidently repaired it. Quote Share this post Link to post Share on other sites
