C5 (X7) too low rider!

[GiveMeABreak]

The fuse box near battery, you probably don’t mean the actual large fuse box? Those fuses look really strange and I cannot find that box.

Here you go:

The BFBD Fuse box is beside the battery as shown above.

Remove the battery and you can remove the unit via the 2 clips circled in Red

It is the Green 40A Fuse shown on the Left for the Suspension Pump.

In my car the battery fuse box has a 50A fuse in that spot and it also says that it should have 50A there. Neverteless, that fuse is broken!

I won’t be able to get a new fuse before evening, but this looks very promising! I was thinking to replace it with 60A fuse to prevent future problems. Is this a bad idea?

Anyway, you totally rock Marc!

Not a good idea to increase the fuse rating. It has gone for a reason - motor drawing too much current presumably.

You could start a fire in the car .

It may be possible to use a higher rating to test the circuit for a few seconds but no more than that.

[Viitonen]

Okay, thanks myglaren! I will just put a 50A there

[GiveMeABreak]

Yes they are officially 40A, so I suspect that this has already been changed!

A warning though - don't increaser the fuse Amp further - or you could risk a fire. The motor is overheating - and as I already said, it is likely to be LDS getting into the motor, either from overspill when filling the LDS tank, or it has got into the seal of the motor. This is a known problem. It is likely to go again until it is cleaned out and reassembled. There are a few threads on this.

[Viitonen]

The car is still a low rider, but only when I say so

I have to check the condition of the pump when it’s not as cold as it’s now in here. Yeah, I’m from Finland.

I’m very thankful for all the great advices I got from here. This is by far the best Citroen forum ever

[GiveMeABreak]

No worries - mobile again - but until you sort the pump out - don't raise or lower the suspension unless really necessary, so you don't over tax the motor and cause it to blow again.

Will a midi fuse show external signs if it's blown out? Will check with a multimeter later today but looks completely fine from the outside.

[osx]

It's the 40A fuse! Will replace it tomorrow and see if the pump springs into life. Otherwise it's time to say goodbye to my third C5.

If it is the fuse you will almost certainly need to clean the motor. The motor has four brushes, and when (NOT if) the carbon dust that is generated mixes with any spilt LDS fluid it combined to produce a conductive sludge. This will cause an increase in the current drawn, and will eventually blow that fuse. This is probably why the C5 I got the replacement BHI system from was scrapped. I paid £40 for the BHI and the maxi fuse box, but quite a bit more for brake cleaning fluid, LDS fluid, a couple of washing up bowls, and so on. I would say the total outlay was about £150. After reading up on the Forum I was able to remove the BHI, get the casing off the motor, and clean up the windings. The following link has the basics of what I did, but has more comprehensive links in there.

I was in my local scrappy on Tuesday, and I did spot an C5 X7. Unfortunately it had conventional suspension, otherwise I would have let you know the moment I got back home.

Your a minefield of information, I hope you don't tell the WD40 story again

[Jay-Bruce]

What WD40 story?

[Hell Razor5543]

What WD40 story?

How WD40 came to exist.

[Jay-Bruce]

There are heaps of origin stories for WD40, 40th attempt at a water dispersant for ignition systems in WW2, War Department #40 lubricant, invented for NASA for dispelling water from early stainless rocket fuselages etc...

[osx]

It's alive. No more Citronics for sure as I haven't cleaned the pump yet.
