Hello All,
Iv had a little problem for the last couple of weeks that i cant get my head around. Every now and again, my GTI is loosing its boost for some reason.. It seems to be really sluggish and not spooling up like it should (put foot down WOT and nothing really happens - My GF's Polo 6n could run rings around it and thats only a 100bhp...
) Exhaust seems loader than usual but no power and cant hear it spool up as it usually does. Feels like im driving a 1.2 clio :-( but then all of a sudden it will come back on and pull hard again as it should. Sometimes this can last 10 mins or hours untill it comes back to normal.
A bit of background info on the car. It's a 05 GTI with 50 something K on the clock, Stage 1 Map, non res miltek cat back, forge diverter valve and pipercross intake. These are the main performance mods (well i wouldnt call the filter a real mod but it came with it lol). It is due a service now and is due the coilpack recall and a software update from main dealer...
I thought maybe the Forge DV or actuator may be getting stuck open and causing it not to have any boost pressure???...
Has anyone come across this before that could possibly help me in getting my power back permanantly
All help appreciated
Adam
