S40 2.0 Diesel Stuttering at 1800 to 2400 RPM
Hi,
Volvo '05 S40 2.0 Diesel stutters while I accelerate through 1800 to 2400 RPM. Outside of these RPMS is all fine. - Anti Skid Service required message is on constantly - The issue had actually disapeared until I took it for an MOT on near empty tank. Now its very bad - Turbo and injector cleaners 'seemed' to improve the issue though I'm still evaluating. - The stutter is like a very smooth up and down, not sharp jerks. - Sometimes I doesn't do it at all but after a recent MOT it's happening alot. - Attached 2 OBDII devices and couldn't get any kind of reading. I was suspecting a fuel issue so stopped allowing my fuel to get down to a quarter tank. I feel like that helped. However it's so bad now that I need it fixed. Any ideas? EGR? Clutch? Turbo? Injectors? Sensors? Addition: As I accelerate through the turbo's range, there is a very obvious sound of air rushing. It sounds the same as if a tyre was being deflated. Is that a potential problem?

Check your charged air intake system for cracks and leaks
Consider anew fuel filter Measure fuel pump pressure.

Service complete and fuel filter changed. They said all the air hoses are fine.
It's still hesitating. I opened the bonnet, a friend revved the engine and I could hear and feel air. I found a split. Its quite bad. Picture is attached. Could this be causing the problem?? Last edited by fixmyac; Jun 13th, 2019 at 21:26. |

That pipe went on my car and lost most of my boost, black smoke and low power. Taped it up for rest of journey then fitted a new one. Now a modified pipe made of rubber, not plastic, but is about £90 !!! Have to take the front bumper off to fit (on the V50 ) anyway. Iain |

No. Unfortunately I'm working nights and really need this sorted. They've offered to pick up the car from my house.
I'm also concerned about the strong fuel smell outside and inside the car! I can't see a leak beneath the car. |
