I would check abs connections on each corner, clean up, maybe some electrical cleaner/spray, see if helps with initial conductivity as that's what it is, slow response to an electrical connection, probably due to the cold.
Lets hope its that easy fix tbh fella, I'll be happy for you if it is.
Yep another one that can attest to the single beep ESP warning as a shot battery. I got mine from here & cannot recommend them enough & the price is very competitive!
E44 Varta Silver Car Battery 77Ah (577400078) - Car Batteries - Varta Car Batteries
That's for mine which is a 2.0tdi bmn 170 bhp. Can tell the difference in starting as its well up on cold cranking amps over the original.....not sure if its 560 or 600 on standard & 780 on the Varta.
it will beep at 4degrees and under it will also show a snowflake, letting you know possible ice on roads... I get a really loud beep which makes the missus jump everytime when turning ignition on its the stupid hands free kitDid a test this morning. The car only bleeped when the outside temperature was under 4C.
Could it be some sort of warning?
