Dear all
hello.
perhaps someone out there can help me. i have a 04 doblo cargo with an ordinary 1910 diesel engine. three months ago when idling, ie waiting at junctions etc, i noticed the revs were going up and down slightly. this got progessively worse until the engine management light came on and it started cutting out at junctions. the management light would sometimes come on whilst driving at speed but would not effect the performance untill i slowed down and then it would cut out.
so i took the van to the garage and they diagnosed, using a read out from the computer, that i had a rotary timing fault. which translates as you need a new diesel pump. a recon pump was sourced at a cost of about £800 and the garage charged £300.00 for test and fitting. Fine you would hope?
Now three months down the line the same fault has returned. I returned it to the garage where they once again performed a diagnostic and again proudly proclaimed it must be a faulty pump!!!!! the pump was returned to the suppliers, who i must say have been very helpful, tested the pump to find no fault. and returned it without charge. so the garage now puts my van back together, tell me its working ok now, but couldnt find what was causing the fault . and charge me another £250.00 for the pleasure!!!!! i Am now begging to feel i am being a bit of a mug and ripped off.
After having the van back for three days the fault once again has returned!!!!!!!!!!!!!!!!!!
Please what could be causing this? could it be the EGR that i keep reading about on this forum or is that just on the JTD?
and what can i do about the garage charging and not finding/miss diagnosing/not repairing my van.

PLEASE I AM GOING MAD

OH sorry forgot to also say that since they changed my pump i have been told that they should of changed the cam belt at the same time. which they havnt done. could this further complicate things?

Help please
 
no it was a local indepenant that a friend recommened. they specialise in diesel pumps. they seem seem to be trying, and beggining to look a little embarresed. however not shy enough to keep asking for money to fix nothing.:eek:
 
With respect, that may be part of the problem. I get the wifes doblo serviced at my local garage and they have done me proud.
I think that for what seems a major problem it needed to at least go back to Fiat for a proper diagnosis.
You can buy a brand new Doblo 1.4 for 7.5k what you have paid out is is horrendous and the reason that I will never buy a Fiat again.
I hope that you get over the problem as someone will be on to give good advice I am sure.

It would be interesting to see other make forums, to see if similar things happen to them. Fiat Techs surely can't be the only ones struggling to understand highly computerised cars?
 
Just need to find a good garage with good techs,plenty about however a quick look at other forums reveal all the same stories you get here.

I assume your meaning 'rotor position sensor' fault,theres only one place I would use to repair this fault but it aint cheap!

Its the weak point of any diesel (the pump) unfortunally if it goes wrong.
 
A friend of mine bought a brand new totr Peugeot and it developed a leaking rear crankshaft seal. He took it back to the workshop where they tried to stop it with a sealer and black paint.
The other thing is how do you know what they find on these scanners. They can tell you what they like and most wont question it. Its because of the love affair most people have with their cars. coochy coo (y)
 
I will never buy a Fiat again.

Why?
It's the one thing you can be sure about with a diesel engine - they go on forever, but when they go wrong, they cost a fortune to repair.
Doesn't matter what make you go for, parts for a diesel engine will always be expensive - and if a garage has to fit them:cry:

AFAIK, if you take a car to a garage & ask them to fix a specific problem - and they fail to fix it, I don't know if they can keep charging you - you need to take advice.

My neighbour came round a few weeks ago, his son-in-law was having problems changing a headlamp bulb.
The only way we could get to it was by removing the radiator grille and bumper to access a couple of the bolts holding the headlamp unit in place, pull out the unit to access the lamp. We were there the best part of the afternoon - and just to replace a headlamp bulb. Imagine taking that to a garage - £100 ?
I was reading on another forum a sad tale of some chap had taken his beemer (or something like that) into the garage for a new bulb & that cost him £125
 
I understand what your saying. The thing that I find on here is that there seems to be an attitude from Fiat that if they find a common problem they either dont admit it or say they dont have a fix. Suspension bushes, some of the earlier clutch's to name but two.
The only way that I can see the Doblo being a reasonably good buy would be to out it before 50k miles and get it serviced where they dont charge nearly 100 quid an hour for a boy to do the oil change.
That way with luck you will only have to change a set of brake pads,oil and filters and a few tyres.
Get half its value back then buy another new one. Cost about 20 quid a week to own a new car every five years.

Sorry meant to write, Get half its value back then buy another new one. Cost about 20 quid a week to own a new car every four years.[/QUOTE
 
Just a note on hiccup's comment... Examiner isnt diagnostics... its a tool to 'aid' diagnostics... in no way shape or form does it diagnose the car, all it can do is guide the technician to a point of concern to which the technician must implement his or her knowledge to find the problem, be it using functions on examiner, wiring or test procedures\methodology.

With reguard to the concern about the fuel pump, you need to find out if the diagnosing garage actually did code read the vehicle, did they investigate other routes? or because they 'specialise' in diesel pumps, they put 1 on it as its what they know and have inevertably reset the error back to stage 1 and its progressivly developing over time to the point of failure, but maybe disconnecting the battery is discharging the capacitors or whatever it is with the fault resetting it again. Just throwing a few ideas into the flow as cant beat a brain storming session on a problem. You may have alternatively been very unlucky and had a faulty pump if its recon, all i hear from people is how bad fiat reacon stuff is, especially their turbo's, luckily havnt had to deal too much with reacon stuff yet
 
thanks for taking an interest essexstu

the garage did actually code read the fault. they also tested for air leaks, fuel suuply, water ingress and broken/faulty wiring.
the pump was taken off and returned to the supplier. they then put it on test/diagnostic rig and found no faults.

if you know of any other tests that might be adviseable please let me know.

regards
 
When I bought my pre-owned Cargo (about 30 000 miles on) from a local Fiat agent, after about 3 weeks it began giving problems on start up. It would start, but rev erratically and roughly, and the engine management light would stay on. All I did was turn off the ignition, wait a few seconds, and then restart. The problem would then be over (until the next time the vehicle was parked for longer than 5 minutes). My initial thought was computer, and that the restarting was resetting the computer. I took it back to the agent I bought it from. They had it for a few weeks, and supposedly played with the EGR and other items. Got it back, only to find the problem re-occuring a few days later. The mechanic came to my office with the diagnostics computer, and plugged it in. Kept on throwing out different errors. Eventually they replaced the pump, and the problem was solved. I am very worried about the pump. Our diesel is not the cleanest! I am worried about how long this pump will last if the other one only did 30 000 miles. I have currently done another 30 000, and (touch wood) still no problems. The trade value on this vehicle is about 65 000 ZAR (3600 pounds) and I dont think the pump will cost less than half that new! Scary thought!! :( My opinion is that the diagnostics program (or the one that this particular agent had) was rather vague in its diagnostics, but then again it was an intermittant problem, so maybe the computer couldn't pin it down properly. Im just thankful I caught it so soon, and that I didn't have to pay for a new pump.
