Turbo replacement, start stop no longer working

I've had the DPF removed, a remap and the EGR replaced plus a new turbo fitted since November and ever since I got the car back from the EGR and turbo replacement about 2-3 weeks ago, the start/stop hasn't worked once.
The garage are saying it's just a coincidence as the electrics and the engine are different and therefore it hasn't been touched.
I know it can be intermittent in cold weather, but it normally won't work under 3c. Mine hasn't cut in once since then which seems to be a bit strange.
Could this just happen to coincide with the car needing a new battery or could it be something else?
Thank god I've got a new car arriving in may, minis have let me down!

No, I'm a traitor and I'm buying an Audi a1! Had minis since I was 18 and they have cost a fortune in repair bills!

Im getting a red one with a silver roof line, so its not quite as bog standard as a normal Audi but it is a bit more grown up than my mini !
There arent many on the roads at the moment either, there are minis everywhere!
Can anybody help with the start/stop problem????

The start stop system only works under optimal conditions, no battery load, no heating or cooling load, engine warned up, battery charge adequate blah blah. I don't recall the last time the system worked on our 2012 cooper S convertible.

I know it will only work when its over 3c and you dont have all the electrics going full blast, but before it went into the garage it was fine, still cutting in a few times a day but since then it hasnt worked once!
I know my car and I know it shouldnt be doing this unless there is something wrong with it!

My guess is that the garage has had the car sitting around with a load on the battery (eg, idling), so it's currently at a low charge level and that's why the ECU isn't letting the stop/start work.

Either a long run, or hooking up a battery charger would fix the problem, if this is what it is.

Where do you get a battery charger?
I dont trust it on a long runs any more, I am trying to avoid driving it as much as possible because I have just lost all faith in it!

Halfrauds 30 charger - I'm sure someone will say that you need to spend three times this for something better, but for occasional use, this sort of thing is fine.

When charging a Mini, I reckon the safety first approach is to disconnect the negative battery lead, so that you can't do any electronic damage to the car with the charger.

so its been back to the garage and he has fully charged the battery and done a diagnostic, the diagnostic is coming back saying the alternator has a fault.
What may have caused the alternator to get a fault?
Seems a strange coincidence with when it went into the garage...

You do have to be quite careful with alternators, they have diodes in the rear to control the charging and these are sensitive.
Thats why you should not plug or unplug the alternator wiring harness whilst the engine is running, weld with the battery connected or short something out, all these could cause a problem to the alternator.
On average the alternators seem to last up to 70000 miles without fault, but as any electrical item it could go at any time.

The guy at the garage said some oil could have got in there whilst the turbo was being replaced or it could be down to its age. Do think I could get him to fix this?
Like I said, it worked fine before!
