Those fobs are an absolute balls.
Handbrake adjusted this morning. They are a fairly easy motor to work on - 15 mins had it done.
Had the door card off, removed the full harness and checked for any broken/ frayed wires to do with the airbags and no issues.
Whats the module @Coog ? Airbag unit?
Cabin end or rear end?
What is £25 in the grand scheme of things, if it fixes the problem
Rust? There's 12 year warranty, I'd both mine replaced FOC through Bavarian.
The ball joints on the lower control arms are pretty common wear item.
Would that cause the issue with really lose steering?
steering joint is common too. joins the steering column to the rack.
with the wheel straight give it small turns and see if the wheels actually move. If there is any slop then its a likely candidate.
