Mission pre heat today...
There are plenty of good guides online on how to do this, so i won't reinvent the wheel..... i'll just add my findings
set the suspension to lift and set it to Jack on
onto axle stands and wheels off, front part of the wheel arch liners off and undertray off...
remove the bumper....
lots to clean within but that's for another day....
remove the drivers side air filter housing and the headlight
it's fiddly getting the aux heater out.... when removing the exhaust on the rear of it be careful when removing it, it's aluminium onto steel.... it will break if you strain it....
it does eventually come out
where the new pump mounts you need to drill out and tap, i did mine M6 as i had a nice Titanium M6 button head bolt...
Build up the new pump and connect the pipes and connect the wiring...
and that's it.... build it all back up and refill the coolant you lost.... about 2 litres comes out when you disconnect the pipes....
Then onto the inside to do the codings....
It gives you additional settings with the HVAC setup on the MMI
and when the timer is set you get 2 little icons on the dash display....
I did set the timer to come on and watch the measuring blocks to watch the pump cycle on and off when playing with the settings....
Can't wait to see it's effect tomorrow morning.... looking at the timer it appears it needs to be set for each day rather than being able to set a weekly schedule.... i'll have to investigate that.....
