Thread: Total Engine Failure 2005 D3 TDV6

Can anyone confirm if OBD2 information contains Oil Pressure?

In the quick investigations (Blackbox Solutions) I have made I can see oil temp but no oil pressure ?

now I have a question - as I have a nice new engine and I don't want this to ever happen again, I would like to put some extra gauges to monitor oil temp/pressure.
What options are there - found a neat solution for older D1/D2 from Madman ECM-2 and it seems with products like "Faultmate" engine information can be read, but I am looking for a solution that I could leave permanently mounted.
Although a computer engineer I am not all that interested in building a in-car PC solution.

Ideal solution in my mind would be a ECM-2 for the D3 ?

Any suggestions

Just read your thread for the first time. Sorry to hear, never a good feeling.

Interestingly at the same repair shop I have seen three or four with very similar circumstances to what you describe. The crank on one engine I had a look at had obviously melted big time. The metal on the crank had that same effect you have if drag your finger over semi-dry glue. I don't know if the bearings had collapsed but certainly at least one of the con rods had decided that was the best time to find a new home via the side of the block.

Possibly you can sensor your way out of trouble, but I wonder if by the time you see any issues developing it is already too late.

Good luck.

The engine only has a low pressure switch, not a pressure sensor.

See Attachments

If that is the case how sensitive is the switch ? Typically by the time the oil light comes on the damage is done :-(
Seems weird that the computer monitors oil temp but relies only on a switch for pressure.
Sound like the only answer is a third party oil pressure gauge - next task find a suitable place to pick-up the the pressure, in the "old days" I would have tee'd off the pressure switch assembly.

You can then choose whatever virtual gauges you want!

Hi Gordon,
I downloaded the App. Can it connect to the ECU via Bluetooth or is the lead necessary?

May have answered my own question.

It would seem in some cases that the big end and main cap bolts can come loose over time. When my engine was stripped down recently they found a number of the caps were only just over finger tight.

My engine was swapped gratis for a new long engine because of a mistake made when work was being done under second hand car warranty, not because of any fault with the engine. They later told me after stripping it down that while the caps were loose the bearings looked ok and didn't appear to be failing.

However if the bearing caps were that lose then chances are bearing failure wasn't far off if the caps got any looser.

I brought my D3 with 92k on the clock in March this year and the service history showed that the previous owner only changed the oil at scheduled service intervals. Personally I think that is not often enough and I will be changing the oil every 5k or so to give maximum protection.

cheers,
Terry
