Hi Folks,
First post and first Merc. Just bought a 2012 E250 Sport two weeks ago. I bought it privately so unfortunately no come back with any issues of which i have noticed there is a few. Im hoping some of you can help. It has 119k miles, full documented service history and in general in very good condition but there's a few small concerns:
- Engine oil leak - theres a minor oil leak that would only be notices with the engine oil pan/guard removed - left running for 10 minutes equals two to three small drops - seems to be coming from the front of the engine but i just cant see where exactly - the oil cooler looks dry, filter housing fine too - any help welcome?
- Idle is a little lumpy when cold, stable but blips up 30 or 40 rpm every 10 seconds or so (idle is about 830rpm) - its very noticeable stopped in traffic - feels like a minor fuelling issue. Fuel filter is just done in recent service and no engine error codes from my diagnostics (basic Launch reader) - one point to note, when looking at the data on the diagnostics the fuel rail pressure looks erratic to me but this might be normal, swings from 25000kpa to 35000kps (see image attached) - this may of may not be related - any help welcome?
- Lastly, im not familiar with these engines but at idle it vibrates a bit, not massively though, hard to explain in text but in park or neutral it feels relative normal however as a comparison the wife has a 2.2 diesel Santa Fe that has definately less vibration in neutral, however, once its put in D or R the vibration significantly increases to a level that i feel could not be normal - had a look at the engine and gearbox mounts and they dont look obviously bad but hard to tell. I have heard torque convertor could cause this but im not so sure - any help welcome?
In general, the car runs well in terms of power, no slippage in the gears, gearbox seems to change very smoothly, lovely smooth car to drive especially on motorways. Not sure how i missed the above issues when buying it, the oil leak aside which i just couldnt see until removing the cover the other two issues didnt seem to be there the day i bought it but maybe they were and i was just to eager to buy it, anyway sorry for such a long post, looking forward to some replies!
Ill keep this thread updated with my progress as i go.
Regards,
Red.
