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 👍👍
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
@@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 👍👍👍
@@mikeberry304 the head definitely plays mind games for a day or 2, sometimes you have to just go with your gut feeling. Otherwise you could have it for another 6 years 😂😂 Also most garages have one of those cars in the yard, turn your head the opposite way every morning 😂😉
You stop breathing just for a second until it gives 😂😂 Brilliant the way you put in the Beru clip & I never knew how the pressure sensor worked. Excellent video thank you Dave 👍👍
Great video dave love the content I never knew that about the strain gauge in the plugs nice to know even though I left the trade . Keep up the great work
That was a seriously nice shot between 3m50s & 4mins. The Teslong saves the day again 💪💪 Some of the cheaper aftermarket bits can be awful but no bother to you Dave to sort it, well done 😉😉 I
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
nice video Dave, ive had those where there electrically fine but the rod becomes stuck, so leave in soak with carb cleaner and normally does the job , well sometimes and customer is happy that they havent had to fork out for new ones . thanks again Dave
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
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
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?
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😊
same block and crank as the 19 cdti, Although the oil pickup seal is a disaster on 2.0 . Tuners have taken the 19 cdti engine to over 400 bhp,, Reliably
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?
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.
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
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?
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.👍💯
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.
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
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.
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.
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.
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.
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😂
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.
@@davesterl not nowadays, it's a whole new ball game, at least there r some cleaver fellows like u about who take the time to find the fault and change one rather than just change all 4👍thanks for sharing the knowledge.
@@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.
Top info on the complexity of emission requirements and of course the cost in replacement.

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

7:30 I know that feeling
Hi Dave what tool you use to clip off the sensors
Wonder if it's possible to use a scope on the pressure signal and plot the in cylinder pressures ?
yes, i don't see any reason why not. never tried tho
Interesting…So in theory you can do a compression test on the Scan tool?
yep
why don't you use high temperature grease on the threads?
Another myth people do not understand. I've covered it in other videos, search for 'spark plug indexing'
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.
Any adaptation or coding this sensor has?
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
Is there any way to know if your car needs these plugs before you take them out
Test them

there are indeed data pids for each cylinder
I think weve all had that scary quarter of a turn moment on modern heater plugs , when your thinking please come undone please, 😂😂😂
hold your breath time
does that code put the car into limp mode ?
usually not
That looked like it was a lot tighter than 10Nm Dave
May appear that way on 1/4 drive
Why no antisize?
