Oil Temperature and Pressure Gauges

[AudiKilla]

Hey guys,

I was thinking of getting an oil temperature and pressure gauge, something like:
https://www.ecstuning.com/b-prosport...16evoot.f~psp/
https://www.ecstuning.com/b-prosport...evoeop.psi~ps/

But where would you connect these to?

Anyone have a solution?

So the oil pressure gauge will hook up to the turbo oil supply line, the banjo fitting is on the passenger side front of the block. You will need an adapter to plumb it in properly. I should've grabbed a pic since I just set one up on my B7 about 2 weeks ago. I will have to dig into were to run the temp sending unit, I am not sure off hand. Maybe someone else will chime in there.

Here is a link to the adapter fitting you will need:

I will see what I can find for the temp gauge! Let me know if you have questions

I will try to grab some pics of my gauge set up on lunch. I run the Prosport Boost and Oil Press gauges on the same Podi pod in the link above. I really like it so far and the Podi pod is way better than the single gauge Newsouth one I was running, it replaces the top portion of the trim on the steering column, blocks from about 20mph and down and 7k+ on the tach. Very minimal compromise.

I will dig into the temp sender location as I am considering adding one as well.

For a bit more, about $250 you could do a Vfiz. You'd have oil temp & pressure, and every other measurement the ECU knows about. The install is much easier.

Let me know if you do find a solution and that pic would help as well, thanks Mike! Very helpful on chat and here

I didn't know oil temp and pressure could be read from ECU. I have p3cars gauge but it doesn't read oil.

So it doesn't need any extra addons or wiring to monitor oil? Would you be able to take a pic of it showing oil temp and pressure?

[wjg22]

I thought that you still had to install a sender and wire it into the p3. Incidentally, if anyone has a DIY for actually hooking it up to the p3 multi gauge I'd appreciate it.

Ya that would be great, I just emailed p3cars to see if they had a solution will update if they do.

However, I wanted a separate gauge for oil temp/pressure so I could always keep an eye on it. My p3cars gauge stays on boost/vaccum all the time

[wjg22]

I read phil's DIY for installing the 42DD relocation kit (http://www.audizine.com/forum/showth...ssure-Read-Out) but it doesn't get specific about how to connect to the gauge. I haven't looked at the back of the p3 since I installed it, so I'm not sure if you just solder wires together or what.

Also, check this out http://www.audizine.com/forum/showth...lumn-pod-w-LED for oil pressure and boost. would be a bitchin' combo, and maybe you could swap out the boost gauge for oil temp and continue to use the p3 for boost. Just a thought. I almost made him an offer but I'm not a huge fan of that gauge location.

So here is one solution I have found for the temp gauge sending unit. From what I read, the drain plug is basically the "coldest" point so it may a bit longer for the temp to rise as it would in a different location, but seems like a pretty easy fix.

Updated link for adapters to run pressure and temp gauges on the B7

Anyone, please correct me if there is a much better location, I have read some people tap it in at the banjo port where the pressure gauge is but I do not see how that would be feasible.

So I misspoke. I can't see oil pressure. Oil temp? Yes.

I would think that's true from what I've seen. That picture above is typical, after parking the car for about 2 1/2 hours at 10˚ F, you can see the oil temp is much lower than the coolant. And it take about 15 minutes of driving before the oil temp is higher than the coolant.

[rongeur]

So I have both oil pressure and oil temp gauge in one. I went the VEI route which is a bit more expensive but matched my VEI vacumm/boost gauge. I purchased through PODI.
http://www.podi.ca/categories/gauges...l-display.html

For the temperature gauge, I ran the temp sender down to the oil sump. There is a tapped oil drain plug that the sender is screwed into. I have one single wire that I disconnect with a simple nut and then can removed the drain plug entirely like a normal oil change.
http://www.42draftdesigns.com/univer...er-drain-plug/

For the pressure sender, ideally you want to monitor the pressure just after the oil filter to get an accurate reading of total resistance going to the engine. Placing it in a different place may alter what you actually want to be seeing for true oil pressure. There is a schematic in the B6 section for the 1.8t oiling system that supports what I am saying here for pressure location. Phil has a DIY for the oil pressure relocation kit by 42DD which is what I use as well. Essentially it converts the oil pressure switch port to a 1/8NPT hose extension that goes to a multiport manifold block that you put both the OEM pressure switch and your gauge sender into it. The manifold has 2 1/8 NPT post and 2 M10 ports. The OEM switch is M10 and most aftermarket senders at 1/8NPT. I think the VEI sender was M10.
http://www.42draftdesigns.com/vw-aud...elocation-kit/

You can do the same with VFIZ or P3 (I think) but you still need to add a pressure sender either way since the OE switch doesn't send pressure information, just hits on and off based on what it sees.

I didn't know that there was an oil temp probe in the ECU, I will have to check VCDS and compare to see if mine in the sump is accurate.

This is good info to know, I should look into relocating my pressure gauge then. I was not thrilled that Prosport did not give me a long enough harness to route it the way I wanted and I didn't have spare wire or my soldering/full electrical tool box on hand ( ) so it had to come basically up the front of the block and back dead center. It is pretty much completely hidden, but I just wanted it routed along my vacuum line for the DV ideally.

Rongeur, any idea how much the different pressure sensor location will skew the readings?

-Mike

[Sales@ECS Tuning]

Also I will need to look into alternative pod options if I want to add a temp gauge. I'm maxed out at steering column now... looks like I am going to have to drop a vent...

[rongeur]

I don't have any hard numbers on how pressure is skewed or if it is significant or not but based on general knowledge, oil pressure is different at different parts of the engine. For instance, the mains and rods get oil first typically and the head gets oil last, pressure will drop the farther it has to go. In other words, you need higher pressure after the filter to adequate lube the head than you need to just lube the mains. I also base this on that for oil pressure monitoring, we want to measure this against audi specs for oil pressure. If they measure at the OE switch port, that is where I want to monitor it as well. Pressure to the turbo journals / bearings is kinda useless in the grand scheme of the whole engine.

Here is what my column looks like now:


I don't have a picture of my pressure relocation but it looks the same as what Phil wrote up in the past.

The ideal location for the temp gauge should be right after the cooler. The sump is an alternative and give a very big picture of oil temp but that is the temp after running through the hot engine and sitting in the pan. I am redoing my oil housing setup now to a Setrab front mount cooler and will relocate my temp sender to the return port from the oil thermostat/cooler.

[canadianA4B7]

Our oil pressure gauges are skewed for sure rongeur. After connecting mechanical gauge and comparing to electric gauge mechanical is more accurate. Both tapped from the same spot on the 1.8T filter housing electric showed lower then mechanical. I used an 1/8" npt T on the filter housing. I can likely grab a pic as intake is off car currently. Give me a few min.

[rongeur]

Ideally, it would be awesome to have a two port manifold with a M10 male on the end and two female ports (M10 and 1/8NPT) without the entire relocation hose. Shoot me a pic when you get a chance. My new housing has a single M10 port after the can filter.

I should grab a mechanical gauge to check against my VEI digital gauge. I would hope a 99 dollar sender is accurate.

[canadianA4B7]

So now that I remeber. I used 2 stainless Ts one I tapped to M10 the other has 2x 1/8" npt. So right I think is oem sensor
Middle is oil pressure mechanical gauge, left is for the VDO sender unit to gauge on column.


This photo is terrible quality.

[rongeur]

I see, you essentially DIY'd the 42DD relocation kit. Looks like a hard line from the housing and a two port manifold for pressure switch and sender.

[canadianA4B7]

Ya I just knew what I wanted found the parts pieced it together.

For the digital gauges you know who sells the sensors/senders?? I need oil pressure, oil temp, I also have boost and afr on gauge 2. Reason being I've tried podi 3x, no response, they still in operation?

[wjg22]

If you figure it out let me know. I'd really like to incorporate the oil pressure reading into my p3 gauge for the peace of mind. I haven't been able to find anything specific on it.

I have not heard they are not in operation. :)

The pressure sender is part of the VEI package, here is a list of all the VEI dealers. http://www.veisystems.com/ws/content/7-dealers
I am pretty sure they are packaged from VEI as the same sender they have on their site is the one I received.

I found one from innovate that looks pretty decent and programmable. They also have an ethanol % sensor and gauge that I'm curious will work with maestro in some fashion.
