Volvo V50 1.6D intermittent loss of power
Hi
I have a V50 (as title suggests!) with the following problem. Car starts fine but it judders a bit when driving, not continuously but a lot of the time. I also end up in situations where when I'm driving at arount 110km/h, the engine stops pulling alltogether and even with the accelerator floored it will slowly lose speed. This resolves itself after about 10-15 seconds without me doing anything, which to me suggests it is not going into limp mode (as I believe that would require me to switch off the ignition and re-start to recover from). While not behaving EXACTLY like last time, the symptoms does remind me a bit about how the car was with a faulty throttle body a few years back. Could this explain the symptoms? Error codes ECM-9140 and ECM-9150 suggests the fault lies there and by checking details the 9140 error indeed gives me a picture of the throttle body. I have also attached the full list of error codes even though I know most are unrelated, but in case I've missed something else that could lead to this. The two permanent ones can be disregarded fully. Last question, if it is likely to be the throttle body, can this be changed without reprogramming anything? (I would guess so since they can actually be bought as a 3rd party replacement, but I want to make sure before I attempt this on my own). Thanks in advance for any help. Other info: - MY2008 - Car has run 155000km, DPF was exchanged at 120000km - EGR is closed off permanently - Car had its annual dealership service a few weeks ago - Fuel filter was last changed two years ago vida_1.jpg |

I had an issue like this and to be honest it took forever to repair. Mine was likely to be down to a faulty ECU but at the same time it could of been the CEM. It has seemed to of sorted out itself now thankfully.

I was in touch with my Volvo mechanic, and based on symptoms and fault codes, he agreed this sounded like an issue with the throttle body so I am getting that changed tomorrow. I will give an update on the result as soon as I've been able to test the car, as I hate when other leave their threads without any actual resolution.
Also, I mistyped.. the error codes I had was ECM-9130 and ECM-9140, ECM-9150 was never in there. Other research also suggests that it is indeed the throttle body, and the symptoms are very similar to what I had five years ago which also led to this being changed. Not very durable these things it seems. |

As promised, here's an update.
Got my car back with a changed throttle body and I don't even recognise it anymore. Not only did it not cut power, it's got way more punch than when I delivered it. So this must gradually have worsened over time in such small steps that I did not notice. So VIDA was spot on when it came to this one. |
