Hi all.
I'm betting someone's had this before and knows exactly what this is. I'm getting stuttering issues in my Mk5 under heavy acceleration when I hit around 4k rpm. It almost feels like a rev limiter kicking in, although of course it isn't that. Eventually it pulls through and continues on normally up to the red line. It's a bit sporadic, doesn't always happen, but it is fairly easy to recreate by accelerating with the pedal flat from about 2k rpm in 3rd, for example.
There's no EML, and VCDS brings up no fault codes either. I've recently changed the air filter just in case it was that, but no.
The car is standard except for a simple Bluefin remap, but that hasn't caused me any issues in the 5 years I've had it.
I fear it's the turbo, but, before I start sending it in for expensive diagnostics, I thought I'd ask here :)
