Vauxhall Opel Astra J Pressure Sensing Glow Plugs

[@colinreid7305]

Top info on the complexity of emission requirements and of course the cost in replacement.

[@geoffg46]

And theres me thinking Vauxhalls were economy cars , £600 for 4 plugs, mate just changed his 1.5 Renault for £20 a set. Great vid, Saved me a couple of hundred quid, 1 and 2 were out. Rightly or wrongly I removed the connectors by pulling up and a slight twist with a sharp wood chisel inbetween sensor and connector. Plugs came straight out. Garage wanted £440 to change 2, bought of Ebay for £240

Good video mate just done mine now cylinder number 3 was bad. Thanks 👍🏻

[@mikeberry304]

We learn something every day Dave, great information, I bet plenty of people will be happy to spend 600 quid plus on heater plugs 😂😂, I had a strange one this week , took a citroen Nemo 64 plate for mot that had been in my unit for a while (6yr) , long story, was accident damaged , suspension etc , always daily started , had 2 cam sensors on whilst in my unit all finished after customer decided he wanted it back , its 1st mot passed no problem , he then wanted it servicing, dropped oil and put a purflux filter in it , started up , ran great , then oil light on on idle , went out about 900 rpm , I had chucked old filter by then , so ordered a different filter from another supplier , dealers no stock in first place , so a coopers filter arrived , exactly the same problem, so thought stuff it ordered a genuine filter , it arrived , no discount from dealers now , compared it to the 2 aftermarket ones , it was about 4 mm longer , obviously presses the bypass spring of the relief valve inside the paper filters housing , fitted it problem solved , slept well that night , crazy parts , will send both the others back to suppliers 👍👍

[@davesterl]

youve had a customers car for 6years, my goodness. yes i try to use filters the manufacturer uses, ie mann, ufi etc alto thought purflux would have been ok unless it was the wrong one

[@mikeberry304]

@@kennedysgarage3281 it was a bit stressful after having the van for a long time and having no engine problems before draining oil , I rang my local engine builders and the numpty there said the chain guide will have collapsed blocking the oil gallery , full strip down he said , obviously I chose to ignore him as the van would do 70 plus mph , maybe he was short of money , wont be going there , 15 quid from dealers for genuine filter 👍👍👍

Thanks for this. Spent longer than I'd care to admit trying to squeeze tabs up to pull the connector off! I have one reading 42 ohms :(

I need 2 for my Astra mate spoke to me mate today and he said there not that expensive so he rang Vauxhall and nearly fell of his seat £148+vat each then found out about the built in pressure sensor so think I’m getting the overtime in at work for 2 new plugs

Interesting tech, expensive but interesting. Thanks again Dave! 👌

My pleasure!

[@eddiejones.redvees]

My 2015 1.6 diesel Astra j as a fault glow plug it has 57.000 miles on the clock because of the low emissions I pay no road tax but the price is the high cost of the glow plugs but thats the price of motoring swings and roundabouts

[@samuesoeilyoriy6581]

great info and testing as always dave. whats intersting about these cdti engines although car is 2014 the block on these is an old fait desgin from mid 80s and in there orginal form from fiat were great diesel engines😊

[@miketucker8743]

Really good video this, I’ve had cylinder 3 glow plug diagnosed as faulty but I’m struggling to determine which if this is a pressure sensor or not before I splash out the cash. Any advice on how to find out?

[@harrym1862]

how would you go about taking the wire off without that clamping tool?

[@soulrider678]

Changed all four glow plugs on the other halves a3 as i didn't know the cylinder order (1-4 or 4-1 etc.) and thankfully only one of these had the pressure sensor, was £90 direct from Audi which wasn't too bad but was the first time I've found one. Not had it happen yet and hopefully won't but do you have a video for snapped glow plug removal? is it a head off job and retime etc?

[@davidbentley6924]

Could you ohms test at the pins on the large connector wiring harness with a battery earth? There's 4 large pins which at best guess are the positives to each plug

[@simonparkinson1053]

A lot of these when failed under warranty at the dealers, they swapped them to 4 standard glow plugs, a new sub loom and a software update. Suppose that was the cheapest way out for GM.

[@davesterl]

interesting, cheers Simon

[@monkehbitch]

That's interesting, I'll be making a call.

[@tmanda323]

1.P0399 Cylinder 1 Pressure Sensor Circuit Erratic Incorrect Mounting 2.P03A3 Cylinder 2 Pressure Sensor Circuit Erratic Incorrect Mounting I have these codes in Insignia with same engine? What to do?

[@stevoc4023]

Why would you not put antiseize on? My insignia has 4 of these and needs the job done. I've watched a load of these videos and some say use copper grease to make it easier to come out the next time. Same guys normally soak easing oil for a few days before. Not being smart, just curious. I reckon I'll leave it in my mechanic because a snapped one on the driveway isnt worth the hassle.

[@davesterl]

I have covered those reasons in other videos.

[@danielwheeler9485]

Hi Dave what tool you use to clip off the sensors

[@19astrasport]

7:30 I know that feeling

[@kevinpalmer7452]

Not come across one of those yet Dave but il be in the know if I do great video. Be good if there was a data Pid for those strain gauges save snapping them off on the way out😂

[@davesterl]

there are indeed data pids for each cylinder

[@nickwain3480]

Garage reader has told me there is a problem with glow plug 4, but all glow plugs are giving off 0.9 ohms. Any ideas? Car struggles with acceleration in cold weather.

[@J90JAM]

I read on a forum that on the 2.0 CDTI, glow plugs 2 and 3 are the sensor ones and the 1 and 4 are non-sensor. The guy stated that this information came from the dealer directly, have you heard this? Also, is the model you're working on a stop/start model? Not sure if this makes a difference but on Euro Car Parts you can't buy any sensor plugs that don't state stop/start.

[@davesterl]

Not too many professional mechanics on car forums. We determine sensor plugs visually. Some cars have 1, 2 or all 4 could be a volkswagen or a vauxhall.

[@J90JAM]

@@davesterl ha true, cheers. Helpful video 👍

I have a question. Do you know where the Coolant temperature sensor on this car is located Polo V 1.4 Tdi 2014? Your help would be much appreciated.

[@daviduddin2130]

My engine is clea. As he'll. Glow plugs are shiny but one needs removing. What's the odds it's going to break on a novice.

[@GoldyCrackFox]

Hi Dave, great video. Can you tell me something? I have astra j 2.0 gtc 2012 with 240k km. 2 pressure sensor glow plug were replaced (the first and the third), it threw an error service vehicle soon. I have no more errors on the board but I have strange vibrations at idle. Engine mounts are good and anything that causes vibrations at idle. Can a bad glowplug with a pressure sensor cause problems and affect the appearance of vibrations at idle? I note that 2 glowplug are old and 2 are new and that there is no error on the board. That vibrations starts after 15 sec when I start the engine. Thanks

[@stu_jam]

Probably dual mass flywheel. If it's a AD20** engine it's a common fault

[@erilev01]

why don't you use high temperature grease on the threads?

[@davesterl]

Another myth people do not understand. I've covered it in other videos, search for 'spark plug indexing'

[@yeshuaisthesonofmantheking4065]

Auto doc, do them allot cheaper they take a bit to come in the post you save a couple of hundred

[@mitchellwhittington9478]

Is there any way to know if your car needs these plugs before you take them out

[@davesterl]

Test them

[@jjjda7441]

Any adaptation or coding this sensor has?

[@markb1487]

I have a question, on a Vauxhall Zafira 1.9 cdti,57 plate..In cabin bad smell,like diesel,plus rev counter is fluctuating/bouncing ever so slightly. Cheers for any advice.👍💯

[@supergeekjay]

Rev counter fluctuations could be a failing crankshaft sensor. If it gets worse you'll have hard starting, or engine will start and randomly die, till the sensor gets too bad, it'll refuse to start at all. Crank sensor is the most important sensor in an engine, as the ECU doesn't know where the pistons are position wise for injection timing, also spark on petrols.

[@TheGibby3340]

Interesting…So in theory you can do a compression test on the Scan tool?

[@davesterl]

yep

[@markhb3346]

Wonder if it's possible to use a scope on the pressure signal and plot the in cylinder pressures ?

[@davesterl]

yes, i don't see any reason why not. never tried tho

[@drivewasher]

That looked like it was a lot tighter than 10Nm Dave

[@davesterl]

May appear that way on 1/4 drive

does that code put the car into limp mode ?

Them pressure glow plugs on a20dt* engines always come out easy no wd40 is needed just get engine up to temp. Standard ones in other hand are more persistent to stay where they're at :D But as everything on cars, these pressure glow plugs can be deleted and replaced with cheaper alternative.

As stated in the video, the wd40 won't do much. Ive seen the pressure plugs break at the sensor.

@@johnfittis5764 In this case the fault code already mentioned cilinder 2 (0:41). Dave checked and confirmed. Back in the day glow plugs didn’t cost an arm and a leg you’d change all of them as the others would be likely to fail too in the near future but with these prices it makes sense to change them one at a time (depending on your circumstances).

@@johnfittis5764 You can chang these to a normal one if you change the software, this is just another way car companys make consumers to pay more for parts after warranty.

Only the plug with sensor is expensive, the other 3 are not!

On this car, all the plugs are pressure sensors. Some cars have 4, some 2, some just one! Try asking next time you comment!
