I think you need to be letting them fix it/check it buddy ?I’ve spoken to the mechanic who advises the TC was not drained so only 7 litres of fluid required.
Also said he had to remove the start stop pump to get access but can’t see how that’s in any way related.
could it be the fact the TC wasn’t drained that’s causing the problem?

This sounds much better for an average bloke like me to do.. How do you actually go about it? Mine will need doing again in about 15 000 miles ( 2.5 years at my present mileage)Unfortunately there are inherent problems when doing a complete "Flush" of the system, (of which I know a lot of people are going to disagree) it can actually do more harm than good.
By "Flushing-out" it can dislodge minute particles which can get trapped within the system, not to mention create air bubbles that can also get trapped. I have known of Transmissions to be irretrievable damaged by Flushing.
Of course it is an extreme exception rather than a rule that this happens - but it can happen!
And I learnt this from a very learned and experienced Automatic Gearbox Technician. He actually confessed that he, (personally) would never Transmission Flush any of his cars.
The way he recommended, and the procedure he follows and advises is to do is a Periodic Drain and Fill of the Sump 3 to 4 times over a period of a few weeks.
This lets the Transmission get used to the fresh Fluid and greatly reduces the risk of dislodging any debris or creating any air bubbles.
This is the procedure I follow and I've never had an issue.
And of course the added advantage is, is that you can do this yourself quite easily!
^+1 I've watched no end of video's on a 722.9 7g+ Fluid and filter change, some with replacing the TC content, some with replacing the HE content, this is the first online video I've seen someone doing a full fluid replacement and if I choose to do the next one myself, this will be my guide without doubt.If you want to know in detail watch this.
If you have the 5g box with dipstick tube in the engine bay , then use an oil extractor to suck the sump atf out every year (3.5L) then add new Fuchs atf4134 which is £28 on eBay for 4L . I do this every year on the CLK .This sounds much better for an average bloke like me to do.. How do you actually go about it?

You need an eBay dipstick £10?
Easy 1 hour job in the sunshine
Yep , I do the filter every 35-40k Miles as well , it just seems such a cheap and beneficial diy job for use long term car keepersThanks Wighty.
What about the filter? Do you change this as well? if so, how often?
I'll be bookmarking this page for when it's my turn.
Do you suck out the sump, drop it, clean it, replace the filter & sump & refill? Do you need a new gasket?Yep , I do the filter every 35-40k Miles as well , it just seems such a cheap and beneficial diy job for use long term car keepers
There should be stuff in the diy section on the 5g filter and oil change .Do you suck out the sump, drop it, clean it, replace the filter & sump & refill? Do you need a new gasket?
I know from here that the correct torque on the sump bolts is vital.
I assume you don't bother with the rest of the fluid in the TC, as you are constantly refreshing it.
