If you get your one out and tell me how you done it, you can have mine
But not flying back to the UK till the 2nd.
Not removed mine yet as possible to test without physically removing it.
Bot no corrosion or anything
Have removed ECUs before, small sockets and squash hands in

Remove the relay, put bridge across tern=minals 30 - 87, start the engine and read live data then
At leatst you know Fery that I won't be ripping it all out and converting.
I am no wwondering if one of the ECU power line in has had a component fried as it ia very much like no 12V on main feed.
If I knew which 12v feed was monitored by the ECU I could place the problem better.

The gist is that when the warning lamp comes as fault detection on ECU request(not for some wiring issue on the lamp's circuit) the ECU cuts the feed from the relay's coil to send the system in locked bars condition then the ECU has no ignition feed either that's why that trick with bridged relay's contact cos then you should be able at least to see the live data for pressures and accelerometers, that data you've seen first is the unfed's ECU feedback so irrelevant

Replace the pressure transducer cos it's suspect with those readings even though if still no fault logged after you removed the relay the ECU is suspect too
And the sensor is expensive aghhhhhhh!
Dropped a loaned sensor in and 15-17 Bar
Same as before, only fault code moaning about the main relay not cutting off (I jumpered it)
So what creates the pressure?
Is it the pump only?
Or something leaking in the block?
Fluid is circulating in the reservior.

Any easy solenoid test?

You'll not get low presure code at 15-17 bar ... just confirm, with bridged relay's contact do you get voltage across the other two cavities where the coil should be?... on another note, the pressure control valve(on the back side) must have 5.6 Ohm and the two DCVs 2.7 Ohm so you can measure resistances
that fault code comes with relay in situ?
