Title: Need a litlle help?
Post by: HALL1E123 on October 05, 2010, 06:39:05 pm

Hi Guys
This is my first post on here, So Hello. I was going to wait until i had got a couple of nice photos but never mind.

2 weeks ago i returned back to vw's when treating myself to a 2005 candy white gti, at the weekend i fitted a Forge twintake and twintercooler.
Since then i have been experiencing a couple of things (hopefully not just i my head :confused: ) and would just like to get some ideas on what maybe going on.

Firstly, I have noticed the engine seems to be quite abit lounder (injector noise/tappety) would this simply be down to the fact that i am obviously no longer running an engine cover?

Secondly, I have noticed occasionaly that on an upchange (DSG) i think mostly 3rd to 4th when the next gear has been engaged and the car is accelerating it sounds as if air is still being dumped, could this be the diverter valve needing to be replaced the car is an '05' and has been mapped and is probably on the original diverter?

Thirdly, Since fitting these two items my idle has gone abit erratic especially on initial stop, could this be the 'PCV' system? just seams abit strange that it never occured before?


Any help will be grately appreciated,

Cheers,
James

The engine on the mk5's are quite load on idle, almost like a diesel, so that's normal,

The whooshing of air you are hearing on the changes will just be the extra noise from fitting the twin take. Do a couple of searches for twintake videos on youtube and you'll see that the noise is normal.

If the idle feels erratic but the needle is not moving whilst still this is also normal. I think a few people have asked the dealers about this has been the response from them

Thanks for the reply cooper,

Im going to change my 'dv' to later later spec any way just to be safe with it having been mapped.

As for the idle issue im not just feeling it, you can actually see the revs fluctuate on the counter.

Are you sure the dumping sound isnt the noise that the engine makes on gear changes as it alters its settings?

Re: the dodgy idle.

PCV issues do cause rough idle, it would be my first change as they aren't to expensive. I would change the DV to the piston type as a precaution as again they aren't that much :happy2:
