RE: Engine Lacks Power and MIL Light On

Dear Colleagues,

When driving following a cold engine start where the engine coolant temperature is <5°C and accelerated with a throttle pedal input >35° and a gear change is made at an engine speed of >2000rpm there is a possibility that the High Pressure rail control valve can stick and cause high rail pressure, which trips a diagnostic, relieves the rail pressure causing the customer to see an engine Malfunction Indicator Lamp (MIL) light on with restricted performance and P1169 and/or P0089 Diagnostic Trouble Code (DTC) stored in the Powertrain Control Module (PCM).

Cheers,

Tim

(thanks Pete for the info)

the only way we could stop ours doing it was to have the coolant temperature over 35 degrees....even then it wasn't a dead cert...but we got less of a death rattle, still a bad rattle but not where near the severity it usually does that brings on the engine light

and the two times I drove it waiting for the coolant temp tp come up before changing to 3rd (believe it or not was quite a long time on a cold morning) I managed to get the car not to rattle at all!! but the next day Ian got the engine light

I never had any symptoms at all - but still they added the patch. I like it - it has heaps more mid range grunt, which I guess you'll discover once you run in your new motor.

I agree with you Scallops.

Mine was 'updated' at my 10,000km service.

Noticeably more mid range.

I have an even bigger grin on my face.

How's everyones car going after the update?? My 110 is running like a bag of cacti It's going into the dealers to get checked out on Friday. Basically when I'm crusing, ie not coasting or foot down, the engine is making a high pitched rattle. Best described as somewhere between a petrol engine detonating noise, normal diesel rattle, and tappets.

It's only doing it when the engine is at normal operating temperature, and if I pull over, switch the car off and start it again it's not so loud, but steadly gets louder the more I drive. The other thing the car is doing is it will start to hunt slightly at idle after a short while, ie stuck in freeway traffic. It's not noticable on the rev counter, but if I plug my Scangauge in I can see it fluctuate from 795 to 805rpm. Before the update it was always rock solid at 800rpm.

Cheers,

Tim

That's not good to hear, Tim - mine has been perfect - but it always was, to be truthful. I certainly haven't had any of those symptoms since the patch was installed. I hope it is not related, but more, that you get this sorted out by LR.
