C5 2007 suspension fault

Post by rogerc5 »

My C5 reports suspension fault do not exceed 56mph.
Whilst being serviced it did several adjustments when lowered to the ground and some smoke appeared. (the service was at a specialist so all usual precautions were taken when lifting).
It seemed OK for a few days but now stopped working; no warnings on start up but I have not been driving, not wanting to push my luck.
I have ordered a replacement pump- meanwhile the suspension pump is not working and the suspension feels hard. It's at normal height- is it OK to drive to the garage ((40 mins on M way) to get it fixed or would it be best to have it recovered?

You can drive, but try to avoid bumps.

If the pump is not working it is relying on the existing pressure in the system, so extreme caution to drive slowly and avoid any pot holes (i appreciate this is near on impossible) and bumps where you can.

This system can maintain some pressure for short journeys as it only 'tops up' the pressure as needed. Sounds like your pump is suffering from the carbon paste syndrome in the motor brushes, causing overheating and a short which is blowing the fuse.

Thankyou for your help folks- I'm thinking that replacing the maxi fuse may be another option before setting off as the pump will not be under much pressure.
I've read about the fuse- does it look like the smaller blade fuses only with a bigger rating or is it a different fitting?

A larger fuse but it likely won't help as it will probably just blow again if there's a short, or soon afterwards...

I had this happen about two years ago. Because the Maxi fuse had been replaced with one of a higher amperage (NOT by me, I hasten to add!) it caused the motor windings to burn out and damaged the bus bar in the Maxi fuse box. Fortunately I was able to get a replacement Maxi fuse box and a suitable replacement pump and motor. I had to clean the 'new' motor (it had the same problem) and replaced the bus bar, but my C5 is still on the road. There are clear guides on this Forum on cleaning up the motor.
