acceleration hesitation

[greencode]

Tricky one to explain but when changing gear there's sometimes a bit of hesitation to accelerate quickly and smoothly. It feels like it slows down a little and then quickly speeds up to normal acceleration (no idea whether I've explained this very well!!!)

It's as though there's a slight lag before accelerating smoothly.

It's a 2017 Golf R that I've owned since new and serviced every year. It's done 41,000 miles.

Any ideas?

Could be a sensor perhaps, have you had it scanned for any logged faults? Sometimes minor one's don't flag up an engine check light. Also, have you ever had the plugs changed, could be related if they are still original. First check for faults I'd say, to avoid chucking money at chasing an issue.

Thanks for this. Just looking back, the spark plugs were changed at 30,000 miles (March '23). I don't have a fault reader but may just buy one and check that. Beyond that is there anything else to check?

I think if plugs were done, get it read for faults, hopefully something in the memory that gives a pointer.

I ran the scanner and nothing came up. I gave it a good drive today and hard accelerated through the gears. It’s strange. When I accelerate it’s as though it’s not a smooth pull. Not sure if this is called a flat spot. It feels like the car is "catching its breath" or hitting an invisible wall before it remembers and starts pulling again.

Any ideas?

Hi ,I had a similar issue with my GTI PP very recently and my car also felt a little flat in general ,I had a feeling it was the diverter valve ,I bit the bullet and bought one from TPS and fit it yesterday ,car is flying now and it's cured all my issues ,the one I took of was a revision C the new one is a revision J ,might be worth replacing yours .
