Good find. I find this problem alot on sprinters where they have 4 component's that use a vacuum supply. And when on starts losing vacuum it bring fault codes up for the other components. 👍👍
Now that I mention it, I remember watching that one. I enjoy watching your videos, sooner or later I could be in a similar situation on a car myself. Sometimes we have to think outside the box to diagnose. Thanks mate
Nicely done Matt. Might be as well just to put a whole EGR valve on it. They’re not to bad to do, they’re prone to failure anyway and the coolers get choked with carbon too. Probably best long term for the customer. Top diag 👍😎
FANTASTIC THINKING ,,,,,,,,, COULD YOU SHOW THE USE OF THE RESISTANCE BOX A BIT MORE AND HOW YOU USE IT MORE IN YOUR DIAGNOSIS ,,,,,,,,YOUR VIDEOS ARE SO VERY COOL!!!!!!!!!!!!!!!!🙏🙏🙏👍👍👍
Hello, I thought I will get there too but my egr hold vacuum too… I just need to check the voltage which I didn’t have yet. I had bought new actuator and waiting to be fix soon. Same error code, also the booster selenoid cut off the vacuum and goes in limp mode. This just give me headaches. Everyone point me to a new turbo which I know is not that
I hat same problem last veek but in my case problem whas brake light swhich on dhe master cilinder i put another brake swich iside off dhe car and i fixet dhe problem .bye .
What's the yellow connectors you're attaching to each cable? They appear to be small current clamps but I cannot find anything similar to buy. Do they clip on, or do they actually splice into the cable?
Hi Ryan, I was giving to T in, and check the vacuum supply to the solenoids. I ended up finding the vacuum leak first and I didn't get round to checking the vacuum supply from the pump. However it would have been good to know the difference, with or without that hose clamped off. Cheers Matt
Howdy! Wv Polo 1.2 Tdi has error P2564 signal too weak! The turbocharger was overhauled. Before the refurbishment it had no error. What can be the cause? Has the sensor been decalibrated and the signal has dropped below the minimum threshold? Actuator rod has no adjusting nuts!
Yes, I solved it! The center where the turbocharger was refurbished changed the actuator to an aftermarket one. The problem was that he put an incompatible one!!! That is, it had the position sensor response values reversed. I went to another center and they changed the actuator again with a compatible one this time. The position sensor values now when everything is ok are: for actuator not actuated - 3.265 volts, and for actuator actuated at maximum - 0.417 volts. I operated the actuator with a vacuum pump, I turned on the ignition, and the values were taken directly at the sensor with the multimeter.
Top man matt I've the identical fault code after fitting a brand new turbo . .I. assuming actuator not set right or faulty as wasn't a fault till turbo was fitted . Fuming as not the best job to change
