Hi guys, I'm after a bit of advice for a really annoying problem my ed30 has developed recently.. A bit of background info on the car; Its just coming up to 99k miles with a full VW main dealer/ my local VAG specialist history, no previous issues, running a bluefin stage1 map for the last 50k miles with VWR air filter and forge diverter valve.
So the issue its got is that it just wont cruise properly with the throttle in a steady state, it feels like you're constantly on and off the throttle (really lumpy). When you put your foot down it will go and deliver pretty much full power, but it hesitates before it does it..
My initial thoughts were fuel starvation, so I changed the fuel filter. That made no difference. Next on the trouble shooting list was the low pressure fuel pump in the tank because it was noisey anyway and seemed like the main culprit. Thats made no difference either...
Has anyone had similar issues or know of what it could be? The ECU isnt showing any fault codes currently, so its not giving much away!! Cheers chaps.
