A big hello to you all!, been browsing the site for a wee while but took the plunge & just bought my first A2 a 2004 1.6 FSI Sport, which i drove back up from London at the weekend returning a pleasant 44.9mpg over the 504 mile journey back up to scotland.
So have notice a flat spot lets call it a hesitation in the acceleration curve, it happens throughout the gear range. So when you put your foot gently on the accelerator & she pulls away smoothly then seems to plateau before regaining acceleration. For me this happen at 2.2 -2.7rpm then off she goes... i have been using shell v power.
Between 2.2 -2.7rpm it developed a judder when accelerating if you keep the revs below 2.2 & above 2.7 its fine, however if say i slow down in 2nd & the revs full between 2.2 -2.7rpm it sort of boggs down (& plateaus) with this judder. Its fine when im in 1st & pulling away, or like i said above 2.7k between gear change but otherwise its the same in every gear & there are also no lights on the dash. The car has been serviced every year or thereabouts, runs fine & once you reach the speed you want she seems to hold it fine. No dash warning lights & DIS confirms 'OK' as well.
Ok so many posts on the forum speak about the following any thoughts??
1. Map Controlled Engine Cooling Thermostat?
2. Inlet Manifold?
2. Missfire possibly coil pack or coil unit?
3. Could it possibly a dirty throttle body miss fueling?
4. Fuel Filter?
5. Something as simple as taking the plugs out & giving them a clean?
6. Aiir leaks such as cap off/dip stick out/ vac line unconnected?
So to answer my own question I need to start by getting a VCDS scan done ASAP to see if that throws up any further error codes.
To be totally honest the seller did provided me with a photo of the OBD2 scan which was my starting point for this post & above info.

Is there anyone in the North East of Scotland that can do a VCDS scan for me?
Thanks in advance
