Hi, I have a c350e (2017), just out of warranty. The last two days I had suspension failure notifications pop and saying car too low. Yesterday was amber and I stopped and saw the rear end was low but once I got back in the car it then said “suspension rising” and then the notification went. The rear had risen again. The car drove fine for the rest of the day. Today I got a red malfunction too low. Again I stopped and switched the engine off then on, got the notification suspension rising and it seemed fine. I drove it home but had called Mercedes breakdown and they’ve recovered it and taken it to my local dealership.

Had anyone experienced this before, where it fails but then immediately rectifies itself?

As it’s just out of warranty I’m concerned there might be a hefty bill to fix it, however, I’m wondering if it is a real suspension failure or a glitch in the electronics or sensors.

Any ideas and thoughts please? :)

Could be either a failing sensor, broken sensor link, failing pump, leaking strut or leaking air line.

Unlikely to be a glitch in the electronics.
Leaking lines or struts will eventually cause pump failure.

Are any of these likely to be costly at a Mercedes dealership?

I'd be pee'd off if a strut had failed on my 3 yr old car o_O

Exactly! I could do with some advice please as to which failures are unacceptable on a 3 year old car (so I can have the financial debate with MB) and which I may just have to suck it up and pay in full

Where abouts are you based?
Also what's the cars mileage?

Any and all are unacceptable. None of the parts are consumable and wear & tear should last a minimum of 5 years on an MB. Take the car back and request that they keep a valued customer happy.

That depends on mileage. It's a different story if it has 10k miles to if it has 100k miles.

Northamptonshire, so it’s with MB Northampton. Mileage is 44500

It was serviced by them in January, done about 200 miles since as I’ve been shielding. Only out of warranty by 4 months, so I’m not happy. I can see a battle coming on!

Ok not far from Craig and I.
MB Northampton are reasonably competent at least.
At 45k miles and 3 years they may baulk at covering the cost of a strut but I'd certainly push them to meet you half way at least. Same with the pump. A sensor I'd just suck up - they aren't expensive.

A strut can get damaged by stone cuts - you'd be unlucky if so and there is no way they'd cover it.

Thanks for the info. I’ll see what they come back with and take it from there. Might come back to pick your brains again once they tell me the cause.

No problems. If they can pull codes that will give a good clue as to the issue.

Update: MB Northampton came back to me saying it was the suspension compressor (?) Said it was £950 but as a goodwill gesture they’d pay 75%. So I have to pay £237

Does that sound ok?

Sounds pretty good to me.
MB Northampton seem to be one of the better dealers.

I was reading the post and was going to suggest ask for goodwill. Reading further down pre-empted that.
If you are not happy with that then ask for more, they could turn around say its out of warranty and you pay it all.

Horses for courses.
