Dark Posted March 17, 2008 Report Share Posted March 17, 2008 yes i have it too, its weird as any rpm above 2k all the way to limiter is smooth as you like. i finally think i have found the problem, which could potentially turn out to be a very common fault. unlpug your HT leads where they connect to the coil pack, check each connector for corrosion, they should all be shiny metal not dusty or dull. also unbolt the coil pack and check the metal connections there. one of my leads and coils is corroded. i have new leads and coil pack on order, hope this solves it. if you have a similar corrosion then it will be confirmed. either way we both have the same problem with our gti.

Dark Posted March 17, 2008 Report Share Posted March 17, 2008 (edited) yes always from about 1700rpm to 2000rpm, never above. the idle rpm is perfect aswell.i have done so much different driving styles to see how it kicks in, but it can come in under gentle throttle or foot full down. i sometimes thought that there is a difference when using 95 octane fuel and 99 vpower. give that a try aswell and see if you notice. but now i think its the coil pack now i have seen the corrosion.

forsh21 Posted March 17, 2008 Author Report Share Posted March 17, 2008 do you think it would be ok just to clean the ends of the ht leads ? Quote Link to comment Share on other sites More sharing options...
Dark Posted March 17, 2008 Report Share Posted March 17, 2008 (edited) i'm not sure. the access itsnt very easy to get a good clean to good metal. and then some material would be lost.you can buy leads singularly from vw. but i have got a high performance splitifre set to go on.

L60UPO Posted March 19, 2008 Report Share Posted March 19, 2008 cheers just had i look the iridium work out at £52 so am gunna order them ta.I had that problem with my gti and a few other VWs that ive worked on. I wouldnt suggest putting denso plugs in as ive always had problems with them, id go for an alternative platinum plug. Also with my gti i replaced the coil pack for a genuine VW one and then had to change the leads, and only genuine VW leads seemed to work.

Dark Posted March 19, 2008 Report Share Posted March 19, 2008 i cant see any reason why non genuine leads or denso plugs would cause any problems? what kind of issues did you discover?forsh21 what make of plugs do you already have fitted?

Dark Posted March 19, 2008 Report Share Posted March 19, 2008 i guess you can get cheap aftermarket leads and high performance ones. i think the splitfires one would be leagues ahaead of the vw ones. they arrived today and look quality. very good materials, twin core inside, and stainless steel connectors, no corrosion there then.

Dark Posted March 19, 2008 Report Share Posted March 19, 2008 (edited) "Limited lifetime warranty"also this is the bit that says the most. although i dont know what limited means lol. Edited March 19, 2008 by Dark Quote Link to comment Share on other sites More sharing options...
forsh21 Posted March 20, 2008 Author Report Share Posted March 20, 2008 tried ma car again this morning and it seems fine hopefully the problem as gone, still gunna change the ht leads tho, i dont know what plugs it as in never had them out. how much are coil packs? And how many miles does your lupo do on a full tank of fuel ? (driving normal) mine is doing about 190 miles to a tank £30. Quote Link to comment Share on other sites More sharing options...
Dark Posted March 20, 2008 Report Share Posted March 20, 2008 i cant remember how many miles, full tank is always a different amount of litres anyway. its around 35mpg but i dont drive for economy.coil packs are £80 from vw, but can get for £50 non vw.
