heavy breathing
Hello all, got a 2008 xc70 d5. Investigating an overboost problem. while looking there is alot of smoke/fumes coming from the oil filler cap, and a load popping noise.
I'm aware that the popping points to a vacuum leak as in the P2 models but unsure where to start looking on the P3 models as the engine mounts are not the same. Any pointers to the smoke or popping would be nice, plus the overboost too..lol |

I have the smoke, fumes and the popping noise coming from the oil filler cap on my 2.4 diesel.
If I rev to about 1500rpm the smoke reduces. I don't have the vacuum engine mounts either and I am also curious about this.

I have same problem. It's probably valve on vacuum pump. Cannot catch time to check it by me, but soon I do it, I will writte you. I will try to fix it, cause 3cm valve is 70€ and I'm not willing to pay so much.
smoke in normal. |
