another long inspection earler and i double checked all breathers and there all fine with no blockages , theres around 5 sensors running the air and turbo system along the breathers and all were tested earler and were all working fine

The only real issue I ahev seen with these engines is gumed up inlets.

Thye seem to get lots of gloop in them which affects the pressure sensors and the swirl pot flaps etc.

So, it is worth removing the 2 inlet sections and getting them chemicaly cleaned.

[tony1980]

yea the inlet which the EGR valve go`s into is really clogged up with crap and have thought about taking it off a few times but now that you have mentioned it im going to ring vauxhall in the morning and see if i can get the gasket ( if there is one ) then take it off and clean it out

took the car to my local garage and the had a look and found no common faults under the bonnet so i aske dhim to mot the car and it passed with just the hand brake cable needing changing but the advisory was they couldnt rev the car over 4000 revs , the guy there says he would put money on the crank sensor causing the problem , does anyone else think this would cause the problem as im am no where near solving this problem

I had problems with intermittent loss of power and EML comming on for short periods and when Tech 2'd it was indicating a fault at the fuel pump. However the tech who did the test suggested the crank senso and water temp sensor be changed first as they both played a part in the control of the fueling via the ecu. Changed the ster sensor first with no change noted over a few days and then changed the crank sensor and the problem has never re-appeared.

If you do decide to change the crank sensor I found the best way to do it was to disconnectthe plug at the back of the engine (near side), loosen off the cable clips and then using a long soket extension removed the crank sensor through the gap between the chassis and wing behind the front passenger wheel. It is a bit akward but better than going in from the top.

ok cool ill check sensor tomorrow i know where the plug is as we just unplugged it and the engine ran bad and started to smoke and plugged it back in and it went back to normal so ill remove it tomorrow as have a look

[tony1980]

Right found a really easy way to remove the crank sensor , first undo 4 8mm nuts securing the sump guard on the passenger side and that side will then drop down , if you shine a torch into the side of the gearbox your see the crank sensor , now using a 2ft extension and a small socket you can easily remove it ..
Now i did this , this morning and removed it to see if i could clean it or see any damage . now i cleaned it up and theres no sign of damage but as i dont have a new one to look at i dont know if its ok , on the bottom theres a small round metal part which i take it sends the sginal but after looking i dont know if this little metal section should stick out the plastic sensor a little as mine is nearly flush and also i noticed 3 tiny grooves in it which go onto the plastic too , now without looking at a new one im not sure wether there supposed to be there
Does anyone know if the bottom of the sensor which sits inside the box should be smooth or wether it has marks

its a hall sensor, so no amount of cleaning (unless covered in metal particles) will make a difference to it.

[tony1980]

do you know if there is supposed to be 3 grooves in it

[Marks DTM Calib]

do you know if there is supposed to be 3 grooves in it

Cant recall to be honest!

Most have been flat from memory

[tony1980]

well mine has 3 curved grooves in , very faint but just able to feel them with my finger nail , need to see if anyone has a new one to hand to look at

hi tony, just joined the site to try and cure your exact problem, i just bought a 2.2dti 02 on tuesday and the girlfriend drove it home from essex(230ml). it seemed heavy and sluggish on test drive but because i have not drove one b4 seemed ok. gave it a dam good clean and took the air filter out last night as it was a bit dirty, left it out and made the small drive to town today to tax it and get the new filter.
as soon as i drove from home the car wouldnt pull and felt wheezy, eng managment light going on/off as i rev. (shit). hoped it was over compensating for no filter so got home and put the filter in,,,, same (oh shit). spent 2hrs looking around the airbox incase i had disturbed a pipe but no. went through all your posts then went out again to lift the air box out to look again.(bare with it).
undone the 1st rubber hose between the airbox and turbo....a 5" leaf dropped out which had been flat over the inlet gauze(blocking it by abt 70%)................hose back on in 5 mins ,, drove the car and it flew!.
hoping you have not removed this hose yet and you have the same prob. sorry to go on but it was a "wtf" moment.
good luck

[tony1980]

cool ill go and look now

[tony1980]

just thought the pipe in-between the turbo and airbox is the one with the airflow metre ( mass air sensor ) is it m8 , as this was stripped last week along with the complete airbox to be cleaned and check all the other pipes beneith it

Lol, hence why cars have air filters fitted  

Thye also stop grit and shite from scoring the bores
