Cheers all.

No issues with the engine before the battery change at all.
Only since the new battery went in - before the battery change at tickover and stationary, it purred - now the whole car rocks.

Will have to pay a visit to Limoncello tomorrow (if OK with him) and run another diagnostic again......

no probs, hopefully the problem will be easily apparent when we scan again.

Very strange. I have had the battery out before, and left the car without battery for days, on re-connecting no issues at all, I didnt have to re-adapt any settings.
However, I too have this rocking, or wobbling on idle since last year, but no problem once moving, as proven by 0-60 time at GTI apparently no performance loss, no codes, no missfire detected. Just a very strange idle, I still havent got to the bottom of it.

Before the battery replacement, just idled silky smooth.
More worrying is when I now put the foot down and it feels really hesitant - like a misfire, but before the battery, not issues.....

Gave it a service (new plugs, filters oil etc) only 3 months or so ago so stumped by what it could be now..

Will hopefully find out tomorrow - will let all know

Default Battery Ground Connection

If all was fine before changing battery....then I would swap it out and put in the old one and see what happens....might be worth checking the connections on the battery and the ground connection.....

Try putting a multimeter across the battery to check the voltage also....should be about 13-14 volts when engine running as the alternator should be charging the battery

They kept the old battery so can't do that but will check the battery as you say during charging.
Hope I get it sorted today otherwise I might have to use the Focus......

Well - its sorted
Not sure if it was the resetting of the TBP (throttle body position) but after putting on around 50 Miles it is running like a good 'un again

Good to hear it was that easy. Resetting throttle body didnt cure mine unfortunately.
