Fitting Vacuum gauge E46 2005

[stewart thornton]

I would like to fit a vacuum gauge and would like to know where the best place is to make the connection as the T piece supplied is quite small.

Thanks

Morning Stewart

What are you trying to achieve by fitting a vacuum gauge ? You have the MPG gauge already fitted surely a vacuum gauge will only convert that to numbers ?

Stirring up the old grey matter there were blanked off ports on the back of the inlet manifold which would be my choice, have a feel

Hi Dave,

I had a couple of spare gauges and the front console area looks a bit sad, so I installed a oil pressure, voltmeter and vacuum gauge. That said as this car is an unknown quantity to me having bought it without seeing it and importing to France, I would like to keep an on the overall condition. I have just being using the Foxwell analyzer 530 and it has proved invaluable  dealing with the transmission issues I was having.

Afternoon Stewart

If you had the gauges and they give the information you need then why not 

If you have an old lap top the BMW 1.4.0 as a diagnostic program should give you everything you need and on the plus side its Cheap about £15 

I use it on all Ibus based BMW's  it allows re-setting of all Fault codes plus it will give access to all control units. If after 2008 vintage then INPA?ISTA is the go to both programs give Dealer level information and access.

Enjoy

Hi Dave,

I have just bought Foxwell NT530 and it is superb. Living in France and trying to get bits and pieces is difficult as they are not big on anything diy. I am trying to find a vacuum take off point on the inlet manifold to tap into. The gauges also add a bit of bling to the inside.

Hi Stewart 

I believe there are take off points at the back (bulkhead) end of the manifold that have plugs fitted

Morning 

The original post was about measuring Manifold depression/vacuum 

Nothing at all to do with the climate control or AC system ??
