Recommend me a screenwash

It's the premixed bottles that cause the congealing in the bottle. I use wurth or sonax.

I code off the headlight washers, buy 5litre BMW concentrate screenwash and use that. Code them back on for NCT. The headlight washers typically spray on every third windscreen spray iirc but that can be coded a little less frequent also, like every 5 or 7.

Yeah going to book with @Germaniks for some coding. Got battery changed a little while ago and everything is factory now
