    Anyone an expert on M273 engine?

    Hi, Thanks, I'm not under any time constraints with my ramp time as would rather not have to start buying a hoist etc. If the timing chain is left connected and the tensioner is removed is there enough slack to replace that toothed gear on it's own?

    Anyone an expert on M273 engine?

    The early idler gears teeth wear out. As there is no balance shaft on the m273 and it is literally a timing chain idler gear. Why can't this simply be done in situ? Remove the cam covers, remove the the timing chain case cover, undo the tensioner, would this not leave enough room to be able to...

    New S Class Owner

    Had my LWB for a while now. Had every option ticked but the factory cocked up the rear fridge. Designo spec also :cool: Post any niggles as I have been down them all and fixed them all myself :thumb:

    Why are dealers so hesitant...

    Indeed by dealer I mean dealership and indy I mean independant MB specialist. No his reasoning was that it's not possible just to turn on aux, the programming (lol) behind has to be manually edited or something like that. I stopped listening and waited for a gap for me to end the conversation.

    Why are dealers so hesitant...

    when it comes to coding a module ( not programming.) On my W221 it is very easy to add aux, buy a £25 cable, wire it into the command, drill the glovebox and snap it in the hole. Then it needs 3 minutes on Star to click the enable aux option and click save. Maybe 2 and a half of the 3...

    w221 S500 Good Old Airmatic

    I used Febi arms. Cheaper than the dealer. If you do the upper control arm, the height level sensor bracket must go back into the hole otherwise it messes everything up.

    w221 S500 Good Old Airmatic

    Just went through this. The creaky suspension is the front ARB bushes. They need gluing with some Devcon.

    Hi there, which are the castor bushes upfront? For the ARB bushes I performed the glue fix and it didn't make any form of difference so it must be these castor bushes?

    Anyone a pro with airmatic?

    Think I ballsed up my airmatic setu0p on my 06 W221. Wanted to replace the upper control arm so I had to move the strut out of the way. So I released the air from the top and undid the 3 bolts. Removed the upper control balljoint and then lower axle dropped and had space to remove the strut...

    w221 owners?

    Sorry, what I meant by handy with a spanner is that I really am handy with it. Whilst I'm not a mechanic, I have built my own private workshop as I got sick of being at the mercy of car garages. This is when I had to replace the bottom end bearings on the M5 :rock: I have the 722.9 adapter and...

    w221 owners?

    Proceeded to replace the control arms and drop links. Made sweet F all difference :doh: Whilst the bushes were cracked it clearly was not the case. So I glued up the ARB and that made no difference. So now I am stuck. The noise comes apparent when cold :confused: It's very much like a...

    w221 owners?

    Thanks for the replies. Well I can live without the rear blind after checking those diagrams :D I haven't checked the mounts from underneath but it definitely feels like a jerk on cold within the actual transmission. Well the filter and gasket arrives tomorrow, anyone want me to make a...

    w221 owners?

    Hi everyone, purchased my first ever Mercedes S500! Love it already but I do have some questions with my purchase. 1. On cold there is a jerk going from 2-3 on this 722.9. When warm the transmission operates fine. The car has only done 50K so I intend to change the fluid as I'm extremely...
