05 1.3 16v cdti - loss of power and EML - Pete73

Hi there, I have just recently bought this van. Now the problem i am haveing is im feeling a slight loss of power every now and then like diesel is blocked for 1 sec or so, but now it's also cutting out whilst driving (Car with spanner going through it sign lights up). It restarts right away and drives and the cutting out seems random.

Ive been and got the codes but the mechanic said he cant tell me what part it is exactly as its a new system and codes and not on the computer as of yet.

He has said 9 times out of 10 its the sencor on the engine but i have 2 on mine and he doesnt want to waste my cash by replaceing one of them and it being the other.

Dont know where else to go to get these codes read except Vauxhall who seem to hold these codes back till they are abit older to have a monoply on the repairing at 160 pounds an hour.

The codes are as follows,

P1191 - Rail pressure to low

P1093 - Fuel system malfunction

P1191 - Rail Pressure range/performance

ty in advance.

slt

Your garage seems somewhat "confused" by these modern systems and is talking garbage. There are nearer 20 sensors connected to this system.

The codes are not witheld and are available to anyone who spends enough on test equipment and data. [Several thousand a year.] You can't do the job now without spending on data and training.

The two codes don't help much; it's looking like a fuel pressure issue, but there are many components involved and guesswork is expensive.

Has it always been run on nothing but pump diesel?

I assume so as its an ex royal mail van which i just bought.Im the second owner after royal mail.

The garage had the plug in electronic scanner but as i said he went to the database with me and those codes cannot be found, but you could be right then that he hasnt paid enough to get the full database or something but hes pretty well known as a good mechanic.

He also did say its a fuel pressure issue but i have just plowed all my cash into this van for work and now i cant work.

Is there anywhere i can get these codes read internet wise or by someone who knows exactly what part it is as im very short on cash now.

ty again for any help.

The garage's scanner must have been seriously out of date; those codes have been around for 7-odd years.... "Good mechanics" are rapidly becoming useless; the world has changed - it's now "re-train in electronics or die."

You have had the codes read; that's about all that they'll give you. Codes are only a tiny part of diagnosis - they point you in the general direction of what the ECU is fretting about.

Particularly with vague codes like those two, they never instruct the replacement of any component without proper testing and confirmation. It's not always a component problem either; wiring, earth and connector problems are just as common.

A mail van will have had a very hard life; under what circumstances does this fault occur?

Its completely random, it might drive for hours with no cutting out and then can happen every few mins.

It just cuts out whilst driving and i can either bump it in gear if i am going at some speed to restart it or i can just re turn the ignition and it starts straight away.

I know mail vans have a hard life this one has done 30k miles and was serviced at regular intervals.

The mechanic did say when he looked under the bonnet that it looks to him like someone has already been down this path as the pump the scensors all look brand new.

ty for your replys.

2005 1.3 diesel 16v cdti - loss of power and EML - Railroad.

The 'P' Prefix stands for 'Powertrain' and combined with the following four digits is a standard EOBD (European On Board Diagnostic) code which on 1st January 2001 for petrol engines, and 1st January 2004 for diesel engines became a legal requirement for all vehicles intended for use in the UK. And many vehicles were EOBD compliant before these dates.

In short, all UK cars and vans from these dates must use EOBD codes, and therefore most if not all EOBD code readers should do the job. Lists of EOBD codes are widely available. Manufacturer's monopolies to a large part ended with EOBD.

That's not the end of the story though. Unfortunately although the manufacturers are required by law to comply with the minimum EOBD, they do not have to allow every part of their systems to be interrogated by any diagnostic tool. Even so, many vehicle manufacturers do allow much of it......

EOBD is fast becoming useless; nearly all the critical codes are now manufacturer-specific ones that the cheap readers can't access.

Reading the few EOBD-only codes will sometimes seriously confuse the issue.

Yes those codes seem useless as ive tried numerous people.

I will change the fuel filter and im told on this model to check the feed pump in the tank ?

Im still driving it like this as im still low on cash but ive noticed if the tank is over a quarter of a tank its fine no cutting out, soo as i get close to Quarter of a tank of fuel it starts happening.

Pete

The tank unit is definitely a good place to look; seems it's not picking-up it's fuel cleanly and sucking air.

Would this also cause black smoke at higher revs as im getting also ?

Is there any easy way for me to check the tank pump or is it a mechanic job ?

Ty for replying and for your help.

Black smoke is the other extreme - too much fuel, or too little burnable air.

Maybe check/clean the EGR valve.

all of the codes mention when checked point to fuel pick up, coupled with your comment that its worse when less than 1/4 tank indicates that the problem may lie in the tank/ swirl pot area inside the tank, well worth an investigation, pay particular attention to the clips on the fuel pipes and the pipes themselves for splits cracks etc, what is the date that this vehicle was registered and how many miles has it done, sorry can't remember if the tank has to be dropped down to gain access, also worth a look under the car to make sure that the tank has not collapsed, and there was a recall/replacement of fuel caps on this model due to tanks collapsing (may be worth leaving the cap loose) Regards TB

Hi - just seen this thread and I believe I may be experiencing a similar problem, brief loss of power/hesitation when accelerating, on my newly purchased combo (55 plate ex BT 29k miles). Did anyone manage to find out what the issue/resolution was? Cheers.

Just had a hunch that the wrong software could have been uploaded to the ecu when limiter was removed!! Also my cutting out problems were being caused by the performance chip I fitted to the fuel rail.. I removed it and now the only problems are the hideous lack of power, the appauling fuel economy and the black smoke (so im told I have not noticed). Is your van a crewcab or a standard van???

Its a standard van. I wondered whether it may be a problem with the fuel filter or something similar? I appreciate your thoughts, cheers.

Hi here's something worth trying. Disconnect the multiplug on the mass air flow meter. Run the van for about 5 miles (the warning light will come on), reconnect it and thrash the nuts off it for about 10 miles (I was told to drive it like I had nicked it. The warning light probably stays on) then leave it (overnight I was told) confuses the ecu for a bit?? Then it should reset to how it supposed to be (Warning light goes out)!! I tried and there was some sort of improvement in performance etc... Dunno if its gonna help cant hurt to try it though!!

Hi all,

I too have a vauxhall combo and have the same symptoms as you guys are having.

Cuts out while on motorway and lack of power getting through the gears and also the black smoke.

I have had the van in the garage twice and they have both said its the air flow sensor, but on changing it with 2 used parts and 1 new part I still get the same symptoms.

Did anyone ever find out how to fix this problem as it seems very common?

I was told it maybe an electrical fault too, but dont know what your thoughts are on this?

Cheers

Hi mate,
Didnt sort mine out yet, but worth remembering, if you need a turbo and intercooler then I have got one of each I changed and had no effect!! Yours for £75 the pair (new ones are very expensive) Cheers Alan....

Just had to replace the EGR valve (part was £106 with discount), following diagnostic check at Vauxhall main dealer, Perry's of Bury. Error code was 'P0400 - exhaust gas recirculation valve stuck'.

My combo van is a '06 reg' 1.3 16 v cdti, ex-Gas Board blue, with 57.000 miles.

Hi all i am pulling my hair out with this fault let me explain:

I have a Vauxhall combo 1.3CDTI 1700

2006 model 06 only 45k on clock had it 2 years had it back from a service and a few weeks later i got problems:

when going up hills overtaking or general driving my engine managment light will flash on and off and i have no revs and little power. to to vauxhall who said it required mass air flow semsor had that changed at a cost of £180

this did not change the problem at all

returned to vauxhall who said it was now the egr Valve had that replaced at a cost of £435

still same problem back to vauxhall again who now say its the turbo!!!

how much more money!! they seem to be just guessing at parts which in my eyes never needed changing as the fault is still the same with no improvments!

i was reluctant to get another part changed sagain so got a second opinion from an independent diagnostic company who informed me it was the ecu which had gone?? no one seems to gaurantee by doing either job will correct the problem?? this is crazy ehat do you pay for a diagnostic for with no certaintys??!!! HELP!! ADVICE PLEASE!!!

PS sometimes the engine sign will stay on for a while but wen ever i turn ignition on and off the power returns untill the inevertable flash of engine managment light comes on over and over again?
