Had to park it this morning on ground that was sloping two ways. This would have really upset it before and had me reaching for the Nanocom. No issues at all.

Hopefully will put this one to bed until it rears its head again…

Back to the problem in hand.

Used to car several times today, every time I started the app it was at the right height and the light instantly went onto normal.

All very strange. The only thing I did a few days back was use my sons code reader, instead of the Nanocom. Ever since I ran things through that it hasn’t missed a beat.

All very strange, considering it has been seriously messing around for the last several months on a regular basis.

I can’t remember the make that he uses, but we’ll find out tomorrow and post up.

Drivers door?

Drivers door?

I will have to wait until the weather warms up again as they chatter lock and unlock when it is warm. Perfectly alright when the weather is cool.

Are you saying that I should check which ones are locking when they start locking and unlocking on their own?

Now if only the random locking and unlocking while you are driving can self cure i'll be quids in!

Another day, all working perfectly. Damn…

How can I look for a fault?

So frustrating, still all working well today.

Amazing! Can’t see this lasting…

Used my sons professional code reader on it this morning. Did the various access/normal/high position dance several times.

Ignition on and off and repeat.

Unbelievably, it is behaving today!

Sounds reasonable. Will check tomorrow.

Cheers.

I didn't fiddle with wires etc.

Just with the Nanocom. I only know half of what I'm doing!

Seems to me that the pump isn't switching on when it is called for but after a while will switch on and behave normally.

Usual scenario: I start the car, (car seems a little low) car wants raising and instead of the pump kicking in, it remains off. I gently drive it when it is low and within a minute or never, it goes to standard ride height.
If it doesn't go up, I can park up, return a while later and it majestically rises after a few seconds...

Just been having a fiddle.

Fuses all okay. Rely okay. Connector in pump box all good. No signs of corrosion anywhere. Car is a good clean example.

Car still on access height. Started car up. Pump not running at all. After a few minutes, I checked the Nanocom and it says rear valves open and then after another few minutes rear rises up. Pump still not running. Checking Nanocom and rear valves close, front valves open and after several more minutes the front rises and now car is at the standard height. Pump hasn’t run at all during that time and still isn’t.

Left car for a bit. Switched to high level. Car tries to rise and gets about 3/4 the way there with pump still not running.

Fiddled about a bit more in no particular order and pump started running for awhile without doing anything specific.

I really am confused!

Thermal switch show normal
inlet valve, open
pressure switch open
lower switch. Open
Raise switch open
exhaust valve close
inhibit switch off
door/disable close.

Used the car this morning.

Everything works quite well. Got home and lowered to access height. Left the car for an hour, plugged in Nanocom. Started car and pressed raise to normal height. Looking at the Nanocom, the compressor stayed off and the compressor is off! Left the engine idling for 10 minutes and compressor is still off with no rise. Very strange. Open to ideas.

Thanks again. You learn something new every day.

I will be having a good look at this later.

I did rebuild the valve block and pump 3 years ago.

Not had time today as a busy family day.... Will get on the case tomorrow!

Are you saying that the pump will run with a door open?

Is the thermal sensor in the pump?

Stuff I will check tomorrow, thank you…
