vacuum

Hello, I am facing a vacuum leak with my Laguna II 1.8L 16v 117HP 2001. From my deduction, it is caused by the o'rings from the throttle body, although I did not have the time to truly check it. I have cleaned the intake and changed most of the seals already. There is only one left from under...

Just spotted what appears to be a missing / broken pipe coming off the vacuum pump on 1.5 dci Kangoo - where should that smaller second connection be connected to?

My brake pedal went hard last week and the garage said it was the vacuum pump so they replaced it. I got the car back and after driving 20 miles or so it happened again. The garage then said it was the breather filter so they have replaced this. It still hasn't solved the issue. It will drive...

Hi all. Couple of things... So I got his 2004 Grand Scenic II with the big 1.9 diesel recently. Previous owner had been mucking about with the EGR and I had to clean that up and reassemble as well as removing a clog from the breather line going down into the engine..the narrower one below the...

Hi all new here! I'm hoping you can all help, I have purchased a Trafic which required a new injector fitting and as you all know they aren't very fun! I have fitted a new injector and the van is firing on all 4 cylinders perfectly. I bought the van in bits as the person who was repairing...

I need to do a brake fluid change... mine is rather black, to say the least. Can I use a vacuum bleeder to do this? It wont damage the master cylinder or abs unit, if I do? Thanks...

Hi i have renault laguna 2 1.9 dci, brake hissing when accelerating, i think its vacuum leak from brake booster, can anyone tell me side effect vacuum leak on diesel engine, can it detroriate air fuel mixture...

Ladies and gents, I am not so much into technical things however, I try to have a look at the engine bay from time to time to see if there is any leaks - if everything is alright with oil and everything. Yesterday when I was looking around the engine, on the left side of the vacuum pump and...

Hi, we have a Renault Scenic 2 1.9 dci with hard brakes, we tried replacing the vacuum pump to see if that helps, it still does not work. we put that same vacuum pump into another Scenic 1.9 dci and it works as if nothing changed.. we did a blue block test to see if the head was okay and nothing...

Urgent help required I have an 09 Master 2.5 that has had all of the vacuum lines removed, now I don't know where they should be plugged in. From what I can there are 4 vacuum lines. From the vacuum pump, turbo actuator, EGR and a spigot on the intake boost pipe, however there are only 3...

can someone elaborate on this black plastic fuel vapour / vacuum solenoid thats situated behind the drivers side headlamp and goes into the canister (fits inside black rubber seal in the canister) behind the front drivers side wheel please. What does it do / whats its purpose and how does it...

Been doing some odds and ends on our GE, this morning i pulled the EGR and hacked off the crusted soot, but i noticed that the throttle body flap is disconnected. Not just disconnected, the vacuum lines are totally missing. They've left the vacuum valve plugged in to stop it from throwing a...

It was easy on my old 14, 8v clio, a T piece inserted into the feed to the MAP sensor and it worked I got some serious MPG out of that car, but now I have the Kangoo of which technically it's the same engine but it doen't look anything like what was in the '94 Clio so I have no idea where I can...

I've finally got around to putting the head back on the Renault but I'm really struggling with the location of some vacuum pipes. I'd be really grateful if you could take a look at the pic and help out with the pipe locations. Pic A shows the two pipes that come from the rear of the head onto a...

hi all... anyone know easiest accessible point on a 05 2.2dci espace to test the vacuum level, and what figures to expect at idle, and higher rpm? I suspect low vac, as I am not getting turbo boost at low revs, despite new genuine turbo and actuator and VNT. I note also now the brakes are not as...

It might be a silly question but is there a vacuum pump on turbo petrol cars?( espace mk4 2.0T ) After cleaning the throttle body I realized I put the gasket back the wrong way.Now I hear a whining noise like a small electric motor. The car drives fine but it throws up p0300 random misfires on...

Can anybody tell me if there is supposed to be oil in the side of the vacuum pump that I have drawn too in this picture Is this normal or has a seal gone between the oiled section That joins on to the cam and this side. Thanks.

Hi, I'm just wondering if anyone has had any water leaks behind the vaccum pump on a 1.9dci grand scenic its using a hell of a lot of water recently, any help much appreciated Jay

Hello, I've broken mine and heard that people often brake a vacuum pipe going to the throttle body with a weird attachment. I've marked it green in the attached picture. Does anyone have any thoughts/suggestions/known solutions to fix it more reliably than just buying a new one which will...
