Problem with power. When I cross 70 mph the coil light starts to flash and I lose power. The turbo seems to stop working, once I switch off ignition and restart it runs fine again until I hit 70mph again, however if I nail the accelerator to the floor it will go all the way up past 130mph with no problem. It only seems to do it while driving sensibly. Anybody else have issues like this and what may be causing the issue?

Any service's lately?

 

Fuel filter?

 

Been scanner with VCDS?

Replaced fuel filter air filter and cleaned air system with egr cleaner. Still the problem persists. My new connector for vcds arrives tomorrow so will see what shows up. Thanks for reply. Will have to keep gunning it till then

Clean air system with EGR cleaner?

Done that. Did not work. I am trying the mr muscle turbo clean. Look like actuator was struggling to move vnt turbo. Will see how that goes! Thanks for reply

I was being sarky

 

Please say you didn't clean your MAF sensor with the EGR stuff?

EGR's knackered, it's DPF/EGR delete time, may as well go for a full Milltek system, S3 intercooler and remap while you're at it

Seems to be going into limp mode could be clogged up turbo vanes. Get a vcds scan as it will identify the source of the issue.

Seems it was the turbo actuator, vanes on turbo were not opening/closing proper. In garage having it replaced. EGR and DPF are fine as is the MAF sensor.
