Hi, I have just purchased a 535D tourer having migrated from Audi (something I thought i'd never do!!)
I used to be clued up with the VAG crowd regards retrofits/coding etc - It currently feels like I've had an arm removed without any diagnostic software :( - Looking into it, there appears to be several schools of thoughts with these cars, some suggest not touching coding at all, some are happy to play but use different systems etc.
What I ideally want is a laptop based solution where I can recode modules and read error codes. I'm reading that OBD2 isn't as quick as the optics (understandable), but what is the cost difference? and would I be able to update systems were i to buy an optic cable? - some places also suggest a good battery charger which i presume is a failsafe as you'd obviously not have the engine running for a 3 hour update.
I have an issue with my iDrive where I will be replacing modules shortly which will need coding up - what is the BM software like, is it as easy as Vagcom to use or are we talking real techy stuff here.
Any help much appreciated
Apologies if I've missed an obvious post giving me all this info
