Yes, I have always had the fuel problem. I always had the sluggish acceleration but now its got worse. The hum hum hum noise only came 3 weeks ago. It sounds like it out of tune. Today I noticed a new thing, after letting go of the pedal when traveling at 30mph approaching a red light I can hear engine tappets out of rhythm. It's not very loud but strange. I am just putting this down to what ever fault I have got. I took out warranty direct when I bought the car, so I will have to wait another month before I can make a claim. In the mean time I might gets the code read one more time. Also been on the forums for a while, there was another member with similar problems who had his egr cleaned. And apparently that sorted his problem. Either way whatever changes are made I will keep you updated, I'm sure it will help someone out there. At the moment I am working on a process of elimination. also I too have also read that reconditioned injectors are tricky and can make things worse.

When was the car last serviced and where do you normally fill up? My belief this could be down to muck in your fuel tank and your current problem due to a semi blocked fuel filter?? This could explain the hum (fuel starvation) and the tappety sound you are getting could be the injectors injecting with very little fuel or no fuel. With my theory it could also be a possible explanation on why injector number 3 had low flow (blocked with crap). For all a fuel filter costs (and sorry don't want you to spend your money un-necessarily) I think it would be a good idea to change it and see if it makes any difference. I know you say it has full service history but if you look at the service sheets when was the fuel filter last changed? All the servicing in the world still won't stop someone possibly filling up from a fuel can (especially an old jerry can type) and this just pouring loads of debris into the tank. |

I have a little about diesel knock, its more like a humming noise, the fuel filter was changed at the same time.
This morning when I started the car I decided to have a look at the exhaust whilst I let it warm up. There was nothing coming out of the tail pipes. It was 8'c so I expected to see some mist or smoke out of the but nothing. After work I took it to the garage to inspect the exhaust thinking the cat might be gone and this would explain the vibration I get when driving a little hard under my feet. It felt like the manifold gasket had gone on my old Ford. Anyway, the car was raised with engine running, only 2% of normal exhaust pressure was coming out of the tail pipes. No smoke and no color. The underside on the engine was checked for leaks but nothing . The mechanic said the problem could be the cat or the turbo due to over or under boosting. He would put his.money on a new turbocharger. He also said its not worth having a emission test as no pressure is coming out of tail pipes. But he will take the exhaust off to check the cat for 70 quid. He can then confirm whether cat or not is fine. One problem after the next. Has anyone heard of this exhaust issue befor? The garage man also covers both dailies with his hands, it made no difference. Any ideas? |

Just had the cat checked out and its fine. I noticed the hose attached to the turbo at the back of the engine which is wrapped in felt is covered with oil. Leukemia fit said it looks like a blown turbocharger? Is this hose easy to take of to check for a split? Is there anything else down next to the turbo whilst I'm down there today? And once the hose is off how do I check the turbo. I'm just looking for other options before I spend over a grand on a new turbo.

I took it to the Indy and he said the turbo is fine but the wastegate is not opening. He then used a souls diagnostic which showed ECM 1200 ECM 1300 and p0244 wastegate solenoid range a. I'm not the rear bottom engine mount looks ok. The top mount has some play, the rubber bit in the top mount is split and cracked. There is a little play in it. On the right of the mount looking from the front of the engine I can put a pen through the rubber. Has thing got anything to do with the wastegat. I'm not sure if the top mount is also run of
On vacuums. This was not leaking on the smoke test. But the test was done with engine off. Please help with this one. I'm running out of cash. |
