Hi, new to the forum even though ive been hitting it a number of years for help regarding my old Y reg sprinter. i have had a problem with the first service on my newley purchased sprinter 313 CDI. Purchased the van around 16 months ago from my local Merc dealer, last thursday it had an A service with the same dealers i purchased the van off. Whilst driving home after service on the motorway the dash showed that 1 liter of oil need, didnt think much as perhaps they had forgotten to fill to required level. Anyway when i got back to my carpark i noticed that there was oil everywhere!!Merc sent someone out who found that they has not tightened down the oil filter cap!! The dipstick came out dry, no oils showing! Of course the Merc dealer has apologised, reprimanded the mechanic and offered me a free service!! Well im not happy as i spent my savings on this van including most from a bank loan and now im never going to be happy that the money ive spent is going to give me reliability, was thinking this might be the last van i purchase for work as im a sole trader.Merc state that only 6 litres of oil were lost and no major damage has been done to my engine, im not sure and will i ever be sure. Can any member give me there thoughts on what i can do next? Perhaps no damage has been done!Thanks for reading this long post but would appreciate any help. Pete.
