Movano fuel problem - statman
I have a Movano van that intermittently looses power and stalls (twice in 140 mile trip). It seems the fuel seems to stop.
Garage have already charged £200 for replacing a fuel sensor but no improvement and now want it back to send it to a diesel expert??
Has anybody any knowledge of this problem or advice as to how to handle a garage who carry out work that has no positive results? Do I have to pay them for all the work?
Thank you

Its ticky to say whether you should have to pay them for all of the work or not, but you need to give them a chance to have another look at it with regard to them fixing the fault properly this time.

If it is a Vauxhall dealer then I would be inclined to say that they should fix it properly the first time, without spending money on unneccessary parts. They are after all the vauxhall agent and if they can't fix it then who can? But if it is as I suspect an independant garage then I can understand the problems they face in fixing intermittent faults, as they will not have any diagnostic gear with the same capability of the Vauxhall agent, therefore I wouldn't be too hard on them. If you don't want to pay main dealer prices then don't expect to main dealer style diagnosis and fixes from independant garages.

I wish you luck...

It's not made any easier to advise on this problem when there's no proper vehicle or fault details. At the very least the year and engine fuel type and size are needed. It would also help to know if there were any fault-codes stored; whether the vehicle was loaded and under exactly which circumstances it failed.

A fault that isn't there when tested is the most difficult to identify correctly - even with £25K of the right equipment. The choice is - "do something" using the "best fit from known faults" method; or to return it unfixed to the customer with a sizeable bill for diagnostic time and an unsatisfactory "no fault found." Movano DCi's around '01-'03 have a known fault with a batch of fuel-rail pressure sensors that cut the engine under full load. Sounds like your garage are on the ball and have, quite reasonably, tried the most likely component first. There can be no guarantees when dealing with an intermittant fault on a system of such complexity.

I've never found that Vauxhall dealers seem to know much about these; you might be better seeking out an independant Renault specialist.

We did take it to the main dealer but they said after putting it onto a diagnostic machine that they weren't sure what was wrong with it.
When you say "under full load" does that mean foot down? Therefore if taken easy it would run fine?

Thanks

Year: engine size; fuel type?

That should be a common-rail 2.5 DTi/DCi; it's one of those that can have a suspect fuel-rail pressure sensor. Is this the part that they changed? Round-about £140?

So; when does it cut out? Loaded? Uphill, level, or when coming to a stop? Were there any fault-codes found at any time? Detailed information is everything when diagnosing intermittant faults.

Yes that is about right - £200 in total.
Looks like the best thing is for me to run the van and try and see some commonality when it stops.
I am assuming this is not something that will get worse. We did have some work done on it by another garage before to get it through the mot so I will find out what they did as well.

Thanks

>>you might be better seeking out an independant Renault specialist.

Wise words! My ex-colleagues in the Vauxhall workshop hate these things with a passion - the very same passion with which we used to despise CFs and Midis! I've heard a few stories from them lately about jobs on these vans which should be easy becoming long term problems - partly because of the, ahem, design of the vans, and partly because of the unfamiliarity which the average Vauxhall mechanic has of these vans.

Carefully built up bonus earnt by servicing, say, a few mkII, or mkIII Cavaliers would all be lost once you were given a job card for any of these awful vehicles. As they weren't popular enough to come through the workshop frequently, it was more difficult to work efficiently, and as such, very difficult to earn any bonus on them. No-one in the workshop wanted to become known as the van specialist, and so, the stadard of care these vehicles received was never great.

Ok - Update on stopping problem, it is the injectors or 3 of them I think!
Any idea on costings for them and fitting and is it worth it??

Thanks

Think? You'll need to be pretty certain before replacing injectors on these. Always worth checking Vauxhall's price [in case they've cocked that up too] but anywhere from £350 up [each] is typical. There was talk of cheaper ones being sold in France; but I can't recall the details.

If you're relying on injector codes alone; be aware that these suffer from poor/loose connexions in the 2-pin injector plugs that often flag-up false codes. I've had to solder flyleads on to a couple. Only excessive spillback is a fairly safe sign of a cracked injector.

has anyone figured out a an answer to this yet? I have been looking for an answer myself for over a year searching movano forums/ renault forums and ones like this, there are loads of vans with the same symptoms, (cutting out, switching off ignition starting again), but as yet nobody has come up with an answer ( including main dealers) .. so far I have replaced-: fuel rail pressure sensor, EGR valve, fuel pressure valve/sensor ontop of diesel pump...

Other than the cutting out the van runs great, its a 02, 2.2td movano

any ideas welcomed

Bob

I had the same problem summer time.It started with a suden engine cut off. Right after the first engine cut off it took longer to get it started. It would normally start in 2 secconds when I turn the key. But after the engine cut off it took like 10 or more secconds when I turned the key.

After a short while it refused to start completely. It would only start with help of easy start. It would also cut off while I was doing 60-65mph on the motorway. I had to switch off the ignition and turn it back on again while I was still travelling at that speed.

I made a mistake of taknig it to my usual garage. They said it is the crank shaft sensor, changed it did not cure it. Than they said it is the little silinder thing on the fuel pump ( i cannot remember the name) changed it nothing. Than they said it is the fuel pump changed it with a seccond hand one and still nothing. Doing all those took more than a week. Than I needed the van took it and started to use it with easy start.

A month and 1000miles later I took my van to a diesel specialist. I live in north west london so I found a diesel specialist in uxbridge and went there. Connect their computer to the van and said rail preasure. It ment one of the injectors was gone. Than he plugged bottles on each injector, one of them was throwing fuel back at the botle. Changed the injector good as new. Their price a bit steep but get they job done. It cost me £72 to check it with computer, £40 for the bottle test, £125 for reconditioned injector £72 for fitting the injector and all plus VAT. It cost around £400 but get it done at the end. It took les than 2 hours to get it fixed.

hi i had the same problem on my 2.5 diesel movano it kept cutting out under load switch the key, off then on, away we go again without even stopping, did my head in, id already had the fuel tank cleaned they said dirt in the fuel ,i had the injectors tested they said 2 had failed had them changed , still had the problem after spending lots of money ..... .. right someone recommended moreys at bridport, diesel specialist, a very pleasant knowledgeable man ,he said it was either injectors or pressure regulating valve on the fuel pump ..he checked the injectors as id only had 2 replaced not long ago i was hoping they were ok, they were fine , and he traced it to the regulating valve on the fuel pump he replaced the valve on the fuel pump, and a bill of 240 pound later and yes its fixed at long last ..so take it to a diesel specialist they know what they are doing not like vauxhall or renault dealers hope this helps someone in the same predicament as i was in
