Hi

    I changed my oil pressure sensor in my last post,because I had a low oil pressure  light in the mornings turns out to be faulty aftermarket  switch.

I change it myself because my mechanic was too busy.

Once I put it on ,I turned the engine on with out the intake connected to the turbo to see if there was any leaks.

After that my glow plug flashes,sometimes if I turn the car on and off a few times it goes out and I can dry it without it coming until I turn it off.

I went to an auto electrician who turned the lights off and said something about turbo settings he changed.

I think he just ripped me off .

The lights is back on again.

The dpf has been removed and remapped.

Thanks.

Presumably most of those fault codes listed have arisen due to running the engine with the turbo partially disassembled. Looking at the scroll bar to the right there are even more fault codes not displayed on your photo?

 

Assuming you replaced the non-genuine oil pressure sensor with a genuine part, and have reassembled the turbo intake correctly then the next course of action would be to completely clear all of the fault codes and wait until the glowplug light comes back on.

 

Once on then you should rescan for fault codes and see what you have.

 

DPF deletes have a tendency to put extra strain on the EGR and other emissions-related systems, the EGR already being a relatively weak component on older / higher mileage / mapped / modified Superbs.

Thanks for that, I have had it rescanned again ,same faults pop up.

On the 2nd page of the scan it says something about  the turbo.

The thing is once it's warmed if turn it off  a few times the lights goes out ,I can drive the light won't come on again until I turn it off,even then it might not come on again.

Until its cold.

We have checked the wastewater actuator that's working,my mechanic took the vacuum pipe off whilst on the it's goes up and down.

Thanks 

 

Just in case - how is the battery? Might be worth keeping an eye on the voltage pre starting. Just wondering about "even then it might not come on again. Until its cold.". If it's running on startup with low voltage for a while it can sometimes throw up strange errors. The combination of cold weather and "fettling" might have affected it's performance if it's getting on a bit, especially following lockdowns etc over the past year or so. 

 

"Cooling fan current circuit low" an interesting message - sometimes a failing fan can take a fuse out. Check battery first though.

Thanks bigjohn

Thanks everybody who tried to help,took the car to a different  mechanic.

He found that a vacuum pipe had come off ,at the back of the engine.

It was underneath,he put another one on and car has been spit on.

Thanks again to everybody.
