Loss of power on hills/no kickdown
In November, I posted the following thread and no-one, in the Forum, was able to offer a suggestion. Unfortunately, after two further visits to the Volvo garage, the problem still exists. It's really frustating, having such a powerful car, that can't overtake on hills. Can anyone suggest any tips please? : I have a 2002, S60 D5 2.4 turbo diesel automatic. It's been a flying machine and no trouble until last week when I attempted to overtake by using the kickdown function. The car went into limp home mode. I took it to the Volvo garage, where it gets regular services, and they replaced the MAF which returned the car to driving normally, except the kickdown doesn't work at all. It seems to jam itself into 3rd gear and it won't go past 60MPH while in the kickdown mode, it's especially noticeable on hills, where overtaking becomes impossible. By easing off the accelerator the gear switches to 4th and normal power resumes. I took it back to the garage and they checked on the lower two engine mountings, fuel filter and the air hoses, but cannot find a problem. The computer delivers the message "Engine Service Required" but the Volvo garage's computer can't seem to diagnose the exact problem. Does anyone have any ideas????

Hi,
Does the car enter into Emergency Mode when the "Engine Service Required" appears? It may be the turbo valve. I will aslo suggest you going to a Bosch Service garage. As you will know our cars have Bosch units, and their reading of the failures may give you a better idea of the trouble. Cheers, |

Hi John,
Is all good now? I have stuttering engine with engine service required coming on. I have changed the fuel filter, replaced the "soft pipe" going into the turbo, removed a ton of carbon gunk form the EGR and air inlet manifold and am crossing my fingers all will be well. Stuart |

I had similar symptoms as you have. I managed to solve my problem by replacing the turbo. There are couple of things you can do:
1. Clean EGR mixer http://volvoforums.org.uk/showpost.p...6&postcount=56 2. Replace the fuel filter 3. Check turbo hoses and intercooler Have a look here: http://www.volvoforums.org.uk/showthread.php?t=69443 http://www.volvoforums.org.uk/showthread.php?t=93560 4. Then you have to check if there is no vacuum leak. Check the engine pads, hoses and vacuum pump: http://www.volvoforums.org.uk/showthread.php?t=88190 5. Check the VNT valve (governor) - it might have to be replaced. This is the first thing you replace when suspecting faulty turbo. This valve controls the turbo and sometimes it fails. http://www.volvoforums.org.uk/showthread.php?t=83830 http://www.volvoforums.org.uk/showthread.php?t=71445 6. Check the injectors. That's very unlikely but they also might casue ECM-6805 problems 7. The last thing is the turbo Here is my thread http://www.volvoforums.org.uk/showthread.php?t=93130 |

Hello,
I am new to this forum and came across this thread. My trusted Volvo XC70 D5 2007 has same issue; loss of power uphill, “engine service” warning light. Several diagnostics and repairs over £1500 later and still not able to find problem. Anyone over the years has found the solution? Thanks |
