Hello guys I’m new here.ive been reading some of the stuff on here and there is a lot of knowledge.
im hopeful someone might be able to help me. I have recently come into my possession a 2010 Skoda Octavia scout estate. The previous owner had given up on the car and was going to scrap it 🤦♂️🤷♂️
It’s way to good. Well it’s a long story so you might need a cup of tea at hand to read this post 😂
so here we go. Oil pump let go on previous engine . So he fitted a Good used tall Bmm engine into the car and swopped everything over, but has never been able to get the car running right. So having spent a few thousand on it including the engine has given up.
so heres the problem / problems with the running. Car starts first turn tickover erratic for first few seconds then idles nicely no warning lights.
to pull away needs more than 1500rpm otherwise will die ,dip clutch and try to rev, will die and stall.
If you set off 1500rpm will move off ok but flat in lower rev range.As you accelerate you can feel it boost then it like a fuel cut and pulls again, stutters as it Rev’s up through the Rev range .After about 2-3mins of driving temp gauge is 1/2 way warm up seems a bit quick temp sense fault ?
then glow plug light starts flashing this goes on for a few minutes . By time I get to work elm light is on as well.
When I read codes on Vcds it store air flow mass signal implausible intermittent,Glow plug 1,2,3,4 open circuit, egr excessive flow. If I clear these out and drive again same faults come back in. I cleared fault codes and disconnected maf sensor, its way better with more power and less stuttering.Finally I took a torsion value for the timing it was -2.5 on tickover. The car to my knowledge has had new egr valve fitted at Skoda less than 200 miles ago, new non genuine airflow sensor , injectors he said they used the best one from both engines. So I would like to diagnose it correctly rather than keep throwing parts at it any suggestions for checking in right order ?
I’m thinking test glow plugs.and loom
change torsion value to -0.5
check injector wiring loom, continuity and connectors on injectors.
i wanted to test airflow sensor wiring but don’t have a pin out or wiring diagram. Lastly I was going to remove egr exhaust manifold and turbo and cooler do egr delete and clean everything and check turbo to see if carboned up variable vanes on turbo.
Any advice greatly appreciated 👍
I’ll update as I go along and share.
ill try to upload images of the Vcds screen shots if I can work out how to do it
thanks in advance. Would love to get it fixed 😂
