Describe your problem in detail. Bought dipstick that were numbered with correct MB part number,they are not the correct dipsticks for this SL65. It appears MB lists the incorrect part number for this car? Just need to acquire the correct dipsticks. Thank you. Mercedes database lists part #140 589 15 21 00. Car is 2009 SL65 model230, engine 275 V12, transmission is 722.6. The dipstick purchased had this part # on it, but the stick is obviously incorrect and way too long. That is for the transmission stick, I had the exact same issue with dipstick I bought for engine oil.
