Suggestion

I don't know as Damper fluid isn't something you really come into contact with but they are both hydraulic fluids so I wouldn't risk it - wash it off well with plenty of detergent, ideally I would use my pressure washer.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi I've found oil on the inside of my nearside front wheel. Any ideas what this could be? :dont know:

POST 2Original post

is it very thick, almost tar like ? if so probably split CV boot. If so its the grease from the CV joint being thrown out through the split

POST 3Original post

Is it definitely oil? Could it be brake fluid?

POST 4Original post

Split cv boot usually leaves a ring of grease around the inside perifery of the alloy.

POST 5Original post

Several brake lines and power steering lines are routed on the N/S. Ian

POST 6Original post

Is it a tip? Doesn't the tip have an oil rad up front? My 850i once sprung a leak like that and it was the oil pipe from box to rad.

POST 7Original post

You've got AC pipes there as well which can look wet if they spring a leak although doesnt really look oily.

POST 8 / ORIGINAL POSTEROriginal post

Thanks Folks, The oil/fluid starts from right from very the top of the suspension mounting/shock absorber, there was a rubber nipple, I recall, could that be the culprit? I did check the rubber gaiter and they all seemed fine. Hope this helps? Thanks

POST 9 / ORIGINAL POSTEROriginal post

I've also remember noticing that it has taken off some paint. Possibly brake fluid or maybe Pentosin?

POST 10Original post

Brake fluid is extremely powerful at paint removal, yes.

POST 11Original post

Sounds like your n/s/f shock absorber is leaking .. fluid will come out from under the bellows or below the bump stop .. lift bellows and take a picture if possible for us to confirm . If a brake fluid leak then you need to get it checked asap .. the pedal should be soft by now . Also as mentioned .. brake fluid is corrosive .. you dont want it on any paintwork ! Some pictures please

POST 12 / ORIGINAL POSTEROriginal post

Thanks, I'm back home on Wednesday night. I do remember the front knocking a little when driving over speed bumps. Is the fluid in the shocker corrosive? I will post pics Thursday morning

POST 13Original post

Im not sure im afraid .. i dont think so , it doesnt really spread that far to reach the bodywork .. brake fluid is if left on paint work .... but if it was that i think you would have very poor brakes by now .

POST 14Original post

I don't know as Damper fluid isn't something you really come into contact with but they are both hydraulic fluids so I wouldn't risk it - wash it off well with plenty of detergent, ideally I would use my pressure washer.

POST 15 / ORIGINAL POSTEROriginal post

Hi As promised. please see picture from nearside front. I had steamed cleaned and painted the inside wing, removing wheel liners etc. So it was very clean before this appeared. Any ideas where this is coming from?
