Can I Get Some Help From Someone Please? Just Bought An 03 Reg 170cdi A Class Elegance.trouble Is,when I Travel At Over 75 Miles An Hour For 10 Minutes Or More The `hi Oil Warning`comes On The Dash And Will Not Go Off Until I Slow To 70 Miles An Hour And Stay At That Speed,i Am Worried That Somethings Wrong But I Dont Know What!

Welcome, have you checked the oil level?? i know its a daft thing to ask but.........

Could be that its slightly over and as it heats up its puting the light on, i would take half of ltr and try that!!

Don't want to alarm you, but on a previous thread on an A class, someone drove with the same "Hi Oil" message and required a new engine as a result.
I would drain some pronto.

eerrr, yes! thats why the warning is coming on! 95 miles on a tenner, would think thats about right, somebody on hear will own one of them and be alble to correct me if im wrong!

Unfortunately the A class engines seem to be as sensitive to over fill as under fill so I'd also be tempted to either drain some or all of it off then refill to the correct level. If the last oil service wasn't that long ago then you could get away with just draining some or all of it off and then putting the correct amount of new oil in with the old filter, but if its coming up for a service anyway then just get that done. Since its only coming on above 70 it doesn't sound like it's much over so hopefully should be fairly easy to sort Do sort it though - its not worth taking the risk considering the potential problems it might cause if left.

Cheers,

Most places now have a oil removal pump, probably suck half a liter out for you if you slip them a drink, takes mins!
