There's a take off for vacuum on the servo line.
Welcome to OOF
When I was trialling the vertical poly bushes, Tony at WIM suggested running zero front toe. It certainly tracked true down the road, but any effect on steering was potentially down to the bushes as geometry.I found 0'' and 35psi increased tyre life,but didn't affect the handling, running at 30psi would allow for more tyre wear, especially in the centre,and on non-XL tyres gave more wear on the shoulders as the tyre flexed more. Hence I use to run XL at 35psi.
With standard bushes I only ever had about 0°06" so can't really say whether the way the car drove was down to the bushes or the geometry or a combination of both.
This thread gives some insight into the murky depths, but there are several thousand posts on the subject over the years.

Front settings:
Camber -1°10"
Caster ~ 4.5° to 5.5° ideally similar side to side and can be improved by moving the subframe.
Toe 0°03" to 0°05" toe in. Total toe 0°06" to 0°10" and even side to side.
Rear:
Thrust angle 0°00
Camber and toe should be similar side to side, but they are a single adjustment and the only number that matters is that the thrust angle is Zero. Nothing more or less, not even a gnats cock either way.
Not mine but my sister-in-laws Mercedes SLK. She phoned to say it had thrown the fan, auxiliary, serpentine belt, or whatever they’re called these days. It had a new water pump fitted by an Indy less than 80 miles ago so I suspected an out of line pulley, but on inspection the tensioner pulley bearing was totally shot. It was the worst I've ever seen and threw sparks out of the bearing.
Fitted a new tensioner and it’s all good again.
for a monthly washSurely you mean annual?
Twice a year seems about right.
Washed the M240i last week. First time since June or July.
It might be tempting to sip the 'illegals' a fiver to wash the car both inside and out but the gritty sponge approach puts me off.
I just put my ML through the IMO car wash every now & then through the winter months ..... far easier!
I am still looking for a Bikini Car Wash like the one Jimbob used. Plus in this cold weather I would be happy to pay double and give a good tip.![]()

Why? What's the difference between a plate or a pan and a car? Soapy water does the job. If you want to protect it afterwards, wax it. The car, not the panwashing with a bucket of soapy waterCan't beat a bucket and sponge, and fairy liquid . Drives the Jaguar forum polishing brigade mental....
Oh lord, You’ve just brought tears of horror to anyone passionate about cleaning their car properly.![]()
That’s exactly right, it strips the wax off.
