vacuum

Hi all, I wanted to check the vacuum lines before bolting the manifold back on as a quick test run revealed a very hard shift. Problem is that I cant see any of the pipes or indeed the vacuum switch which looks to be attached to the IP? Also I only have one white nylon pipe going to the box...

I have an '84 230 CE running project with several issues. The vacuum central-locking hoses have been disconnected and removed from the engine and I cannot see where they would have been connected. All that's left are the junction boxes and the the hoses that emerge through the bulkhead into the...

Hello again, Stumbled upon an interesting observation, or was this a co incidence...? The headlight level adjuster (the rotary switch near the headlight switch) had no effect in the level of the lamps, so decided to look into it. Found that the previous owner had (reason unkown) disconnected and...

Does anyone know where its located? I'm refering to the modulator itself and not the pressure adjustment valve on the side of the gearbox. I'm guessing its under the intake manifold somewhere but would like to know for sure before i take it off!

Hi everyone, I'm new on here having just bought my first merc... a mint black C220 elegance. I've already sorted a little issue i had with my wiper thanks to the great 'how to' bit on pinning that gear, now i've got a it of an idling issue i'm hoping someone may be able to help with. I can...

Hi everyone, I seem to remember someone on here had their car tested for vacuum leaks fairly recently by a company that specialised in carrying out that kind of work. Am I imaginging things? My google-fu hasn't turned up anything. I'm desperate to sort the central locking on my W202 :(

As previously posted my gear changes on the 190D tend to be a bit thumpy at low revs, so I am going to check out the vacuum lines. What's the best way of removing them, heat them up with warm water and just pull them off? Is there a risk of damaging them? Also, there are 2 down on the engine...

Went to see a fella whose breaking a 300CE 24V, & whilst looking at my car & chatting he said he reckoned I must have the plug gaps wrong (rough idling). I told him that I had followed the 0.8mm detailed in the Haynes manual, and explained that the plugs in fact came pre-gapped at 0.8mm anyway...

hi, after pulling Bills car apart, and replacing the stereo, and everything back together, but i still dont have air from the centre vent. When you adjust the dial, i get demister and feet ( these are cable driven) but when i move the dial to the vents the centre vent isnt opening to let...

Hi, My 2000 SLK 230 has suffered from the usual problem of damp affecting the PSE unit in the boot. The interior light had a mind of its own, the central locking was eratic and often locked and unlocked whilst driving, and I had occasional false alarms. Having taken the unit to bits, the...

pulled the door card off to tinker with the electric window motor and now seem to have no central locking. I've looked at the russian site and the diagram looks straight forward enough but of course all the bits in the way are not shown.. Could someone advise on how to trouble shoot vacuum...

Ive just found a vacuum pipe flapping around in my engine bay:crazy: , its located between the bulkhead and the engine and leads to the drivers side of the gearbox, there is another pipe from the near side of the gearbox which leads to the inlet manifold, thats in-tact thank god:bannana: . has...

The central locking (and other bits) are not working on my old car (w210). I know it is the vacuum pump under the back bench. Does this have a fuse and if yes where is it. Are there any common faults that can be home fixed.

Hi All, Has anyone had cause to record the routing of the central locking vacuum tubing and would care to share the info? My symptoms are: Locking the car from the drivers door, all the doors, boot and petrol flap lock normally. Unlocking the car from the drivers door results in only...

I need to find out what all the vacuum lines are coming from the inlet manifold because I'm fitting a supercharger. There are 6 vacuum lines I can see: 1. small pipe to the fuel pressure regulator 2. small pipe to the MOT valve (what is this?) 3. larger pipe to the brake servo 4. small...
