Bilstein front shock problem

[Edd]

I have a problem with one of my yellow Bilstein front shocks

It's been off the car for a few weeks, lying on it's side

Went to put it back on yesterday and it has leaked a very small amount of fluid

Obviously with only using them for 300miles I ain't happy

BUT I've lost all the paperwork for them when we moved house few years back, looked everywhere

I bought them through Courtenay

Keep using them? I guess once they start to leak this will just get worse?
Will they still be under warranty? Even with no paperwork?
Go through Courtenay? Or Bilstein uk? If a place exists

Anyone with any ideas/input (that's helpful resident spammers ) I would really appreciate it

Drop them an email and see if they can do anything to help. Also give Courtenay a call and see if they can provide you with a copy invoice relating to the original purchase.

Pay with card? That's proof of purchase if ya did

unfortunately, any warranty is usually based on length of time owned, not miles covered. i think you'll be peeing into the wind a bit. maybe they will service/repair them as a goodwill geasture. its worth a try if you don't get any joy on the warranty front.

They can't be 3 years old Ted.

How much fluid loss? I'd try them on the car, it's quite likely you won't feel any difference.

I did have a thought, Grant Baker sells Bilstein stuff through his tuning business, he might attempt a warranty job if he's in a good mood. Courtenay might also, if you can get them on your side, it's usually the retailer that persuades a supplier that replacement is required. Isn't Jon Shield on here? Maybe PM & some pics will help your case.

Sorry to bump an old thread but...

I have just taken delivery of a brand new Bilstein B12 suspension kit and opened it up this morning.
when I got to the front shockers the pistons, seal and body above the spring cup were covered in a clear oil. Now is this just assembly oil or is there a problem? They are the yellow big piston shocks so the piston is in upside down. Is the top seal an oil seal or dust seal?

Hi,

The top seal is a dust/dirt seal to keep the crap off the lower piston/rod.

I would say it is just assembly oil or an anti-rust coating.

I have a couple of sets of NOS Irmscher Bilstein Cup shockers in the loft, I will check them. I have wiped the pistons clean and left them on their sides overnight to see if it is coming from the seals.

[Novasport]

Just checked a set of my Irmscher ones and they have some red oil on them. Looks to be just assembly oil but I will check the others tomorrow to see.

Mine haven't leaked anymore fluid, had them hung upside down for a few days as well

I'll report back when I drive it again, no idea when that will be tho lol
