BMW Z4 3.0 in need of TLC
Posted: Mon Oct 07, 2019 8:45 am
3 weeks ago a lady from PTA got in touch with us and wanted some help with her car which was purchased a year ago. She had the car at 2 independent workshops and BMW themselves who quoted her a staggering amount to fix the car. So she asked if she could bring the car to us and have it properly checked out as a second opinion.
The vehicle was dropped off with us and we immediately got to work ...
We begin with diagnostics as the car was not seeing a lot of modules after bmw attempted to run diagnostics. Start with checking the battery , it was low so put the car on charge and get the battery up before plugging in the laptop
1st round of diagnostics show the lack of Comms to a lot of modules .
After reprogramming the abs and airbag modules we ran diagnostics again a 3rd time and now we can connect to a lot more
Also checked the fuses
And the wiring , just Incase.
Next we needed to address the coolant leak
So we started stripping the cooling system
Things were brittle and breaking
Started collecting parts for the repairs and services needed
Cooling system
Filled up with Coolant and distilled water mix
Belts, tensioner and rollers
Old belt was wearing unevenly
New parts fitted and torqued to spec
Control arm bushes worn and not seating correct
New vs old
Apply thread lock
