The vehicle hasn’t stalled or surged since the SCV replacement, plenty power and I’ve done the service changing all filters including the diesel filter ... 👍👍👍
Hi. Thanks for video. Do you know any way to prolong life of this valve? Changed my half year ago , use just shell v-power, and have same problem again
I have recently been working on a 2011 Astra J 1.7 with the same issues ..OBD revealed a misfire on No3 .All injectors sent off for testing and found to be satisfactory .Further tests then done showed engine ran OK when cold but started to run poor when up to temperature. Eventually stalling and difficult to restart. This was found to be due to heavily blocked DPF, with exhaust disconnected starting OK .Further testing with engine running revealed that there was excessive smoke/soot being produced when at operating temperature this was identified to No3 injector over fuelling at tick over when hot but fuelling normal when above idling ,installed a new injector but this gave the same fault condition i.e. ran normal till close to full operating temp' followed by over fuelling at tick over. A compression test showed Nos 3 & 4 cylinders to be slightly lower than Nos 1 & 2. .Thus followed a strip down to remove cylinder head ,this revealed a hairline crack between Nos 2 & 3 and a slightly wider split between Nos 3 & 4. Cylinder head overhauled new gaskets etc original injectors fitted engine teste and running fine .Had to use DPF cleaning fluid to clear exhaust but just of interest the blockage was at the "Cat" end and took quite a bit of shifting to get the DPF to regen' .I have come across similar symptom's to this but not by the this cause. Hope this is of help to someone ,note head removal on these engines is not for the inexperienced.
Cool good to know mate, I did test this one for PWM, resistance and couldn’t find anything wrong I was concerned about making the wrong call until opening up the thing 😊👍👍👍👍 cheers
@@pifcudoidef How do you clean the scv and with what products? Also do you need the recalibrate the scv after cleaning or is it only necessary when replacing the scv?
Cheer mate , still getting used to the MaxiCOM some procedures doesn’t seem to work like I expected to and so much more functions I’ll get there at one point 😊🤣🤣🤣👍
Really informative, thanks! This seems to match the symptoms I see in my Zafira 1.7 CDTI. Time for me to borrow a graphing scan tool for confirmation, I think 😄
I have problem only when the car idle. It starts perfect , runs perfect, no stalling, no limp mode. Only when its idle i notice strange engine work , not smooth and the RPM arrow is moving a little . Could it be the same problem?
Its could be, however, more likely the EGR valve or the DPF is full of soot and dirt. Look online, its easy to take off and clean… if its blocked full of black stuff, clean and go on a long motorway drive (1 hour) at high Revs. Engine needs 50% diesel to do a DPF regeneration.. that was the issue with mine
Great video! One question: Do I need to do the calibration on the computer after changing the pump or is it enough to just change out the part and drive? I can change the part but don't have a computer to hook it up. Greatful if you reply!
After replacing my SCV on my astra J 1.7 (i used Denso the original part) i turned the key to ignition and the "dpf is full please continue driving" icon poped up...any ideas why that happened?
got a same car with 2012 1.7 LPL cdti and replaced suction valve and pressure at idle gone to 6795psi goes back in limp in cannot find the fuel pimp adjust valve unless its a 2013 model will this adjust itself as still erratically goes into limp in
I put a new fuel rail on my astra j cdti 1.7 it starts lumpy kicking out smoke I turn off restart it it runs lumpy but much better then clears it’s self any ideas. I’ve cleaned egr run ok for couple weeks but back to square one please help.
Thanks for this - I've been searching for low power issues on YT and checked your vid out. I've had no issues at all with my car in the 6 months of ownership but during my last journey home it suddenly lost power and really struggled to accelerate. I was in a 30 zone so was keeping my speed just below this and thankfully managed to 'limp' home at just over 20mph. Over half a tank of diesel and no warning lights to indicate any issues.. The car would idle OK, just this strange reluctance to produce normal power when using the accelerator.. If the problem persists I'll remove the pressure regulator as you described and go from there.
Great vid this is happening on my 1.3 cdti on idle pleny of power when driving drops around 100rpm lights dim etc. Garage says its normal eco tech system do you think i could have the same problem.
My mokka 1.7 keeps stalling at junctions and roundabouts … I’ve just had a full service , new glow plugs , new SCV, fuel filter and it’s still stalling ? 🤷 do you know/remember if it comes up with reduced engine power etc when stalling ? Thanks for any help , it’s driving me mad
Bom Dia, I have an opel 1.7 110 cv,2011 and basically when i leave it in idle after a few seconds the car shuts down, showing on the screen power reduced. This is happening only at idle. Running a test says is the fuel regulator. I would like to do the job, but i dont have the tester to teach the regulator. Do you think i can remove the sensor clean it and pop it in, or do i have to use a program to programm the valve again? thank you great video!!
@@ingusandersons3800 hi there, sorry for the really late answer, probably you fix it. Anyway the problem was about the a little high pressure fuel regulator. A tiny device that cost me around 300€.
The pump regulator valve does not always fail, more than 50% of the failures are due to the pressure limiting valve that is in the fuel rail, not the sensor, the limiter is a bolt that protrudes from the common rail rail. It remains open and the ramp pressure drops No siempre falla la válvula reguladora de la bomba, mas del 50% de los fallos son por la válvula limitadora de presion que va en la rampa de combustible, no el sensor, la reguladora, un perno que sobresale de la rampa de common rail. Se queda entreabierta y baja la presión de la rampa.
@@Liveforeever I had same issue changed the scv and it returned 2 month later, took to garage they changed the camshaft sensor and it been fine since that was a year ago,
@@CarsExposed you cant beat euro car parts a long as the get the part right you know what they are like I like the discount codes lol another good video the scanner you have is a great tool but a expensive one lol

Mine hasnt got that far but my idel is all over the place sometimes jumps up to 2l/h at idle and at higher rpm's works fine but at lower ones sweet jesus there is no power at all barely takes off and it is killing me. I either risk stalling or take of like a lunatik there is no in between.
Try replacing the camshaft sensor, it's easy to do and cost around £37 all the videos I find show scv but actually most are a faulty camshaft sensor, it can't read cam position causing misfire, stalling when idle, cutting out, iratic idle surging etc
Lol I have this too, I can literally have no power at one roundabout, the next one I take off like a fecking rocket. Makes me feel a right twonk at times lol
@@mrdaveofdaveshire4047 Well i replaced that valve and it didnt do much. I learned that my injectors are fcked the issue is bigger than that valve. I have the 130HP variant which is blessed with the Denso injection system which no one repairs since denso does not supply spare parts and i have to either buy remanned from denso or new or risk repairing them with chienese parts. With bosch injection my life would have been so much simpler. This 1.7 diesel on this generation is nowhere near as realiable as it was on previous generations.

No need to replace the cvc, cleaning it does the job as well
I guess in most cases , I think this one would be ok with some fine sand paper or something but the owner referred to replace it 👍👍👍 cheers
