In relation to my comment yesterday in the other video related to the scv, I also thank you for publishing all these tests in this video. I would like to share the tests that I did on our 2.0 d4d 126hp engine: Surely it is a coincidence, but I carried out quite a few of the tests mentioned here, although we have not changed any components since I highly doubt that something in the injection system is broken , so my actions were to clean the mass air flow sensor, clean injector connectors, fully charge the battery (about 6 hours disconnected from the car) and then dismantle the original scv valve to perform an internal cleaning with brakes-cleaner fluid and isopropyl alcohol. The car is 17 years old and the week before cleaning the SCV the idle was unstable, it was increasingly difficult to start and it ejected a lot of black smoke when accelerating hard. The results as soon as I installed the clean SCV valve were surprising, the car immediately returned to normal. When I saw in your previous SCV video that you installed a compatible one purchased on eBay from China, I suspected that this was not a good solution and now in this video it is clear to me that it was not. My next actions will be to continue monitoring the fuel consumption and operation of the car, I would like to be able to clean the scv valve better since I could not remove the circlip that blocks the inner cylinder, I have to get a tool to be able to do it without breaking anything. I would also like to tell you that Toyota replaced the original valve model with an improved one since the first one had problems over the years, I have been able to confirm this with Toyota. It is also true that in countries like Scotland, calls were made to users to change the SCV due to problems with fuels with an inadequate proportion of sulfur (info obtained on internet...), I think it is important to share it. If it's okay with you, I'll share my results in this video. Thanks and greetings again.
With respect to all the solutions, for people in UK, use Tesco regular fuel or premium is even better, after every month or two. If Tesco fuel is not available then Esso.
Soory Just to say it's running pretty good now. A lot better after all the work. But still intrigued whether Re set would still improve. Many thanks
i will try , tnx 🤞
Thanks for replies.
What was the problem? Mine has started perfectly since using the Mannol Diesel Jet Cleaner. I've changed all the filters and glow plugs. Best wishes
Also as you seem to have same motor t180?
How reset ecu , by disconnecting battery negative terminal? For how many time?
After you Re fitted original suction control valve and drained all power from ecu did it Re set everything quicker than first time?
