A question relating to how a vacuum brake servo works. This from Wikipedia: ''When the brake pedal is applied, the movement opens an air valve which lets in atmospheric pressure air to one chamber of the booster. Since the pressure becomes higher in one chamber, the diaphragm moves toward...

Bought this W123 230 CE on Sunday morning and I've spent the last two days going through it to see what needs doing. Monday we spent having a look at what mechanical/electrical needed sorting and found that, on the whole and for its age, it's in good shape; Bit of a blow on the exhaust, Only...

Hello, I wonder if anybody could tell me if the soft close function on the w215 CL or S class' pulls the boot lid down from the rear of the car (so just on the latch) or if it for example pulls the whole lid down, evenly at the same time thanks in advance alex

The other day showing my new CLK 240 2004 convertible to one of my friends, I opened and closed the soft top via the remote control pointing to the door handle sensor as per instructions, but that was the only time it has worked!!. I've been trying again and again unsuccessfuly. What do you...

It seems like it's the season for auto-trans problems. After many miles of faultless service my 1998 E300TD is now sticking in various ratios ... Usually when warmed up ... sometimes it's 2nd. Most often it appears to be 3rd. Once it's started, it won't change out of this. Putting the selector...

Is it normal for W638 courtesy/interior light to ONLY work with key in ignition? The remote toggles dash lights on for a short period when locking/unlocking...and interior light work and toggle from door switches, but only when key is in??? Baffled!

Hi Guys Just bought a 2008 CLK Cabriolet Avantgarde (C200) The soft top does not respond via the remote fob! Anyone know if this is a standard option on CLK Cab & how do I tell if I have it if its operation is faulty ? (not working) Please help B

Good afternoon, my first question (of many I am sure). The offside door mirror took a gentle knock recently and the electric adjustment only works up and down, not left to right, so I want to inspect the mechanism. But how do I get in to look, since the cover is one piece?:confused:

Hi Guys - Quick question re boot lid operation on a brand new E Cab this possibly applies to the E Coupe also. When I release the boot lid remotely from the key or inside the car it doesn't open all of the way itself, this obviously isn't a major issue....Just a bit irritating. Does anyone...

Hi all Think I might be going mad. I have a 2002 UK 320cdi s class. According to the manual I pull out the round light switch to level 1 or 2 to enable the front or rear fog lights. I know I don't have front lights but assumed rear fog light was mandated for uk MOT. Problem is light switch does...

Hi guys Have a 2005 CL500- Can anyone tell me how to remove and refit the control facia for the passenger seat controls. Mine seems to have worked loose and the vibration rattle from it is driving me nuts. But I dont want to force it off in case I break a fitting/fixing. Appreciate your help -...

Hey guys, Need your help. The car was running just fine. All of a sudden started switching off the engine as if there is no enough fuel going to the rail. Then ended up complete impossible to drive. Engine simply was shutting off and not starting (manual gearbox). Waited for a friend to pull me...

I have a SLK200K which I bought that had received a trivial back end tap. I replaced the rear bumper and had the o/s rear panel repaired and it now looks good! The only problem is with the operation of the roof/windows. When the roof is closed, all fits well and level, but when the roof is...

http://www.haulnet.eu/resources/uploads/files/MetPol%20Operation%20Catcher.pdf I received a PDF with identical content to the link above today, which was sent to our firm by our road risk insurer. I believe it's not a joke, although I couldn't find any reference to "Operation Catcher" on...

Does anyone (e.g. Richard or Alfie) know if the option to operate the roof from the keyfob on the facelift R171 SLK is just a coding change or if there's any hardware involved?

Good morning everyone… I know I have touched on this before but I still don’t seem to have any real pointers. I am still confused by the way the external lighting works on my W220 Sclass, it something that I have not been able to answer so far. Basically the headlamps work when the keys are...

Would someone knowledgeable :) please explain how the electric fans on my car are supposed to work? I've noticed recently that they appear to be running at high power just about all the time, regardless of engine temperature and I'm sure they didn't do this during hot spells last year (I think...

Hi I have an SLK 320 2002 and was wondering if anyone knows of a mod to the remote key for central locking the doors that could open and shut the roof as on the lastest SLK range. Thanks for help Tex

Hi my roof is playing up on my CLK 230k cab sometimes windows go down when open roof but then nothing if I close windows and try again sometimes works ok . Had roof down all day went to close nothing tried switching off and tryin again started to pannick as looked like rain then worked ok...

Can anyone confirm whether using the emergency key (key insert in the remote unit) is a pure mechanical operation when used to open the drivers door or does it still require the electrical central locking mechanism. The reason for the question is whether it still works when the battery is dead flat.
