Hi guy's hope all well pretty much ever since purchasing my mk2 vrs cr I've had oil dilution with fuel and rising levels due to this.  I know this is meant to be due to either failed regens or regular short journeys. Yes my Mrs does do some short journeys during the week to work but she does get a proper blast at weekends to hopefully clear out the dpf. I've had zero warnings on dash reg the dpf or any poor performance issues indicating a blockage. Car drives fantastically. Has anyone else had similar issues with rising oil levels. We went on a 200 mile round trip and level rose about 1.5-2mm. Car has 152k miles but still sounds like new. Somehow the fuel is ending up in the sump assumingly passing the rings?? Any suggestions?? I'm changing oil every couple months!! 

Since you appear to have a 2008 car, are you sure it's a CR and not a PD, engine code BMN?   My old, 2008 Mk5 Golf 170 which I bought new in mid 2008 was a PD.  If it is a PD then I'd suggest that the tandem pump might be leaking.   

 

The only other likely cause is leaky injectors, particularly at that mileage but since you say the car is running well....

Following a quick Google, it appears that the CR engines are prone to tandem pump failure resulting in the same symptom of fuel in the oil. 

Hi its definitely a common rail engine. I plan on removing the injectors next to see if any seals are passing up into the rocker. I didn't think the cr's had a tandem pump?? 

Many thanks for the reply bud.
