Lazy starter symptoms plus fault codes

[Aaron.s]

Hi all I’m new to the forum and have recently purchased a 2017 ex rac t6. The van constantly struggles to start the starter is hesitant and turns engine over slower than I would expect. The garage had fitted a new battery but still the same . Also had it checked by local battery centre and both have told me it doesn’t need coding to van ¯\_(ツ)_/¯ (could this be the issue?) they have now booked it in for a new starter to be fitted under there 3 month warranty. After reading about the Carista I picked one up to check to see if there are any faults and found these could any of these be the issue?
Thanks Aaron

Garages avoiding my Body Control Module fault (U0140) - affecting Start Stop

Third unsuccessful visit to a garage so reaching out here in the hope someone can help. In a nutshell, T6 2016, 100k miles, dash says Start Stop error but no other problems. VW say "no comms with BCM or alternator. We think it's a break in the wire" but won't give me a price for fixing it...

Not exactly a fault - just notification of elevated NOx emissions. Possibly needs a software update to "fix" the issue. Please post "Detailed ECU info"-report (under Carista Service menu).

I don't think any of the above are related to lazy cranking.
