Title: Loss of power
Post by: Joeb3006 on June 05, 2026, 06:42:49 am

Morning all, my GTI is stage 1, recently when driving under heavy load, I get total boost loss, and the car goes into limp mode. No lights on the dash though. Then with a quick ignition on and off, everything goes back to working until I boost under heavy load a fire times and then the same thing, total loss of boost.

I was then sat in a lot of traffic and booted it to get away, EML came on, and again total loss of boost. But this time after an off and on, I still have no boost.

I know I need to give it a scan but I’m currently in the south of France and without a scan tool.

Has anyone had a similar experience and if so, what was the cause?

Thanks in advance guys

Could be loads of different things, as you know, it needs to be scanned. Could be overboosting, underfuelling...anything I'm afraid.
