Hi, Yesterday I carried out an engine oil level comparison check on my 2004 W211 E320 CDi (3.2 litre, straight-six). The engine was hot and I gave it a generous 30 minute rest period for the oil to drain back into the sump. First I removed the engine cover and took a dipstick reading of the depth of oil in the sump - the oil depth measured 130 mm. Then I used the dashboard electronic service measurement system to take a measurement of the volume of oil in the sump - this was reported as 6.5 litres. From the oil level check charts that Russ (SM rf065) kindly posted for me, the 130 mm oil depth requires 0.5 litres of oil to bring the level up to the full mark. I was told that the correct (full) volume of oil in the sump is 6.8 litres so, if that figure is in fact correct, the electronic service measurement system is telling me to add 0.3 litres of oil to bring the level up to the full mark. A discrepancy of 0.2 litres between the two measuring systems seems rather high. Please could someone with access to the WIS database look up what my E320 CDi 'sump full' oil volume should be when using the dashboard electronic service measurement system? If it is actually 7.0 litres (rather than 6.8 litres), that would relate perfectly with the 130 mm dipstick measurement. 2004 E320 CDi (3.2 ltr. straight-six) VIN: WDB2110262A606222 Engine No: 648961 30 076464 Thanks, Razoo BTW, I topped-up with 0.3 litres of oil (Mobile 1 0W40).
