Turbo lag
« on: 25 June 2015, 22:10 »
Hi guys,

I have a mk4 golf gti 1.8T I'm having problems with my turbo. Quick run through, my engine management light came of for my lambda sensor and mass airflow sensor to be changed so I replaced them right away hoping that would solve the problem, unfortunately it never, after two days of driving the car was running rich (thanks to the help on this) I easily fixed that by replacing the rivets on my secondry air pump. The car turns over smooth and runs smoothly but when I put the foot down to enjoy the car between 3rd and 4th gear roughly around 3 to 5 rev mark it loses all the power and within seconds boost again, is there anyway to fix this or this a warming for a new turbo or fixed by remap?

Thanks

scan it/get it scanned, if its only when in boost then I'd be looking at the dump valve, actuator or the turbo itself.

did you replace the MAF with a new one or a used one?
ARZ K03s, Oettinger Side Skirts, R32 front, Carbon stage 2, Forge 007p (yellow spring), Forge Actuator (yellow spring), Pipercross panel filter with DSG parts, N249 and N112 deleted, SAI deleted, Carbon canister deleted, Rear wiper deleted, Long Life turbo back custom exhaust with 200 cell sports cat, VR6/G60 clutch kit, Creation Motorsport TIP, Catch can, 'Wellycooler', K04 charge pipe, S3 ported inlet manifold - looks pretty standard on the outside though :)

I just tried PMing you, but suspect you don't have sufficient posts for messages to work.

I live in Edinburgh, I have Vagcom, happy to help if I can.
