A couple of weeks ago on one journey I noticed this problem but it disappeared on the next drive and I forgot all about it. Today my car has been into Audi for a four wheel alignment and as usual I took the Bluefin off before I took it over.
So they finished with the car and I took it away with no problems but had a stop-off on my way home. I took the chance to reload the Bluefin while I was there and now the problem has reared its head again and it's a lot more prominent.
A picture paints a thousand words so I took a video of it:
There are no gear changes involved there by the way and it doesn't matter what gear I'm in. It normally happens somewhere in the 3-5k RPM area although I don't think it's exclusive.
I'm assuming that since I have reloaded the map its been highlighted massively by the map learning mode and there's a bit more fuel being pumped in than usual. It certainly feels like a fuel problem, as if too much fuel is being injected, it's not being burned off fully so the ECU is then holding back on fuel delivery.
Has anyone experienced this before? Or got an idea what it may be?
Unfortunately I don't have my VCDS cable with me this weekend to check anything but can anyone suggest something for me to check/measure specifically which would be of use?
Many thanks!
