Loss of 12v Power on Ignition

Are you sure you’re pushing the brake pedal down far enough to disengage the brake switch to get it to start. Many have failed at this point and sit there simply turning the ignition on and off again.

It still has a brake interlock. I never mentioned a button.

No brake interlock on starting the D3. But the interlock does stop you taking it out of Park.

It’s a struggle - we even have to open the bonnet to check the oil level, and don’t ask how we can lower ourselves to change the oil. Urghhh!

So, following Brad's advice, I cleaned the terminals and bingo, it fires up first go..........but now the EAS has decided to lower itself to the stops. Aaaargh!

Battery related, or coincidental? Dash error: 'Suspension Fault. 30 mph max'.

Diagnostic tool shows no fault. :wacko:

I would put money on it being voltage related. Clear fault and see how it goes. 🤞🤞[emoji106]

Pressure sensor voltage at all corners is 4.9v.

I have done a 'Hard Reset', to no avail and checked the 70A relay. Relay clicks in and out and shows 0.000 ohms resistance.

I can hear the compressor working normally, too.

Might be time to give my friendly, local auto 'leccie a call and the lure of an ale or two.[bigsmile1]

'Terrain Response' not available either. Due to the lack of height, perhaps?
