So what have you done to your car today?

[Doctor Gollum]

Unfortunately, the strut attached to them and is secured by grub screws which are prone to seizing.in place.

Clearly a Friday afternoon in Sindelfingen when someone decided that was a good idea.

Well, they used the same system on the W220 and at least the W221 uses an external hex head instead of an Allen one

 Not done by me as have no facilities to do so but Engine out of the Monaro on Friday

[Raeturbo]

What for?

[Sir Tigger KC]

What for?

He's replacing it with an electric motor!

Managed to get two of the screws undone. Turns out they're actually E10 torx. The garage can fight the other two as they have a bracket stuck over them making it almost impossible to get a decent purchase on them so rather than round them off I have soaked them in oil and let them be.

Also started to investigate why the rear windows don't work. Some basic poking got the motors out and established that the motor physically turns freely and its gearbox moves without issue, as do the regulators... I did wonder if the windows had stuck in the frames, but the regulators move without issue if you manually move the windows, so frames lubed with PTFE spray.

Electrically, the switches work but there's something amiss in the door ECUs as there is a short between the two power feeds to the motor regardless of switch position which suggests a fault within the door ECUs as they contain relays  that supply the motor rather than a software issue.

Much simpler with the handles you wind up and down.

True enough, thinking about it, I have only owned two cars with manual front windows... A 1985 Sierra L and a 1988 VW Polo.

And only 6 cars with manual rear windows... The problem with modern cars is that everything runs off a network of boxes rather than old school mechanical switches, fuses and relays. Downsizing in the name of progress

Check though as door motor controls usually short the motor out when its stationary, this provides a level of motor braking and works as an E-stop if there is an issue.

There's no change at the motor when the switch is actuated up or down... Zero voltage and continuous circuit between + and -

Sunny and mild in Suffolk so gave it a wash. Being the uncommon silver, i didn't realise how bloody filthy it was. 

[TheBoy]

So very nearly lost at fuel station roulette.   My arse aches from clenching for several miles...

[Keith ABS]

What for?

Uprated heads and cam and doing the upgraded timing chain, tesioner and oil pump while its out
LS7 clutch kit just ordered from Rock Auto.
I have AAS headers and 200 micron sports cats waiting to go on when it goes back in
Was hoping for about 100hp increase but since been told once the map has been done, it could be 130-140 increase
Bit to close to 500 so may have another big bill of 3k for the big brake kit

[Raeturbo]

Lovely ☄️☄️🔥👍😁

[countrywoman]

Oooooh nicer smoky burn outs then!!
