My 54 plate 1.7di vauxhall combo seems to be running way down on power. It only started this morning and its that bad that i sometimes struggle to get up the slightest inclines. Going up the M62 earlier i was struggling to hold it at 65mph and had to change down into 4th.

Theres no other symtoms, the engines running fine and is still smooth and there are no warning lights on either.

Anyone have any ideas on what i should check please???

Cheers.

Check the pipe that goes to the map sensor - had exactly the same problem with my TDDi Focus Saturday and a clever man called Ian @Power Dynamics sorted it for me in 5 minutes the car was still smooth but no boost and didn't want to rev etc. The pipe fixed it instantly.

our golf tdi was similar and was the air/fuel sensor. Car was basically in limp mode

Mr S1, that sounds like the same symptoms as mine. Its as though the turbo fell off. Ill have a look at that in the daylight mate, cheers.

Lambchop, wouldnt that bring the engine light on though mate?

nope!

Well the engine light has come on this morning and the problem seems to come and go. One minute its struggles to get to 60, then it judders and its back to normal speed again, although the light still stays on.

So its obviously going into limp home mode as you suggested lambchop.

Im trying to find out how to do the paper clip test on the ecu connector but cant find any info for the 1.7di combo engine. Ive done the test on loads of petrol vauxhalls but never done a diesel and with me not being able to find any info suggests that its not possible on my engine maybe?

Any help on this is appreciated. Cheers.

it sounds like limp home matey

i have had them that come and go and its one of them Vauxhall
things,we have had loads of them that looking in the service history
have had problems which when fixed a few days/weeks/months
come back on and its usually somthing stupid.

is it a di or a cdti ??

Its a 1.7di mate, 2004. Yes mate ive had the light on many vauxhalls before and it is usually something small. Ive always found the fault myself with the engine light flash test by bridging the pins on the diagnostic plug, but i dont think i can do it on mine being a diesel. Well i cant find any info in it anyway

hi does anyone why the service light on my 03 combo 17di comes on and it goes like a bullet yet when it goes out I may as well push it, not airflow meter or broken wire, im told its the ecu really trying me now, cos need light off for mot

Edu common problem

Remove and Check map sensor they get coated in thick carbon shit very common......

Ecus are really comon on these.mainly tend to cause other problems like cutting out when warm and not restarting is the main issues iv seen them have.also ecu is repairable if you know what to look for.also as said above map sensors clog up.check turbo wastegate isnt siezed up.also boost solenoid valve pretty comon to.

This should work on that age of van to tell you what the fault code is without diagnostic machine! Used to work on my Corsa.

could be many things mass air flow, split turbo pipe, egr valve, brake light switch, clutch switch, faulty turbo etc

tryingverytrying

seems to be an abnormal voltage at the air flow meter, tap ecu and prob stops for a while but comes back, am told its a dry joint, annoying, HELP

you aint got fuel in your ecu have you?i presume its got the ecu on the top of the engine?

tryingverytrying

cheers, its on the top don't think theres fuel in it, no clue with diesels at all, had to scrap a my berlingo last month cos no one could sort it for me so I got this one, think il just take the bulb out to get it through the test

tryingverytrying

codes are 0100 for airflow and 0370 for egr valve, could this be the problem I hope, told to take it off and clean it but don't know what im looking for HELP PLEASE

mechanic28

as I remember the egr and mass air flow share the same voltage feed are you sure you have not got a broken/corroded wire? Specially at the front panel?

Piston Broke

so after reading all that it could be anything lol, listen mate work/own a garge and you need the van scoping and ECu read to see codes or its guess work and wastes money buying loads of crap you dont need, my money is on a dry joint on the ECU, but this depends on what engine you have as there is a vauxhall engine and a Isuzu engine in the same CC etc fella good luck

creator

As mechanic 28 has said egr and Maf are on the same circuit and normally when ones not working properly it will cause the other to be affected.

tryingverytrying

cheers for your replys, im told its Isuzu low blow but it say Vauxhall on the cover, problem seems to happen only when engine gets warm, me thinks its egr thingy by what ive read, il take it out and clean it at the week end and let you know any more suggestions will be greatly appreciated
