Title: Ex plod 2002 MV6 auto cutting out
Post by: Mick_600 on 30 August 2007, 20:43:52

Dear all. Had a strange problem today. Driving along and she just stops running (auto box so sudden lack of power steering makes life interesting ).  :o

Engine turns over fine, plenty of battery power. I Left it around 10 minutes starts up and runs perfectly ....... several miles later, stops again with no warning.

When running the engine is perfect. When it stops, ignition light and oil light come on and no others. No engine management light warning so things like throttle body and crank sensor seem unlikely. Haven't been able to check for fault codes as my reader is at my mums .... typical ... but wouldn't have expected any with the em light not coming on.

I have just had a cam belt and rollers changed by a local specialist (£160  :y ) but having watched them do it they know their stuff, should do they used to build V6's at the factory and also the engine runs a lot better than it did before the change due to valve timing now being correct on both sides rather than just the one side which was the position before they did the work !! Still it was only like that for 40,000 miles lol. Seriously though bits they disconnected such as throttle body would cause the engine light to show and it doesn't and all leads are still correctly fitted and secure.

Any help would be very much appreciated and also if any of you are in the North West (they are near Chester) and need work doing at a good price by guys that know what they are doing rather than kids learning what to do, contact me and I'll forward your details somehow.

Thanks
Mike

ps sorry for tending to ask questions rather than help others but I am not yet sufficiently knowledgeable about these yet to be sure my advice wouldn't make things worse.

Hi,
     My 1999 MV6 had a similar problem. It turned out to be the Mass Airflow Sensor. The analogue output signal drifts up and down when the unit gets hot. This has the effect of making the mixture ratio go out of limits and the engine loses power or stops.
   The engine management computer is still receiving a signal from it, (albeit erroneous), so it does NOT light the engine management warning on the dashboard. It will log a fault code by comparison of other sensor inputs, which can be read with a fault code reader.
   A secondhand MAF sensor is about 60 - 100 quid and a new one is about 280. Bosch are aware that these thin-film type sensors have a limited lifespan, but have done very little to correct the problem.

   The crankshaft sensor on my car has just failed, so I will be joining you in the "oily hand" gang this weekend.

   Have fun.
