what happens when your engine earth lead is not only loose, but also covered in rust & debris? A 4v volt drop across the earth resulting in approx only 8v worth of useful electricity actually making its way to sensitive engine electrical systems & the starter motor. And not forgetting, enough arc to allow the earth lead to (technically speaking) weld itself to the body! 🧩🔋

recent customer of ours had been having issues with loss of power & an illuminated EML. During our inspection of live data, we found suspect values from the MAF, DPF & EGR. Upon further inspection, this was found. This is the result of a faulty EGR (Exhaust Gas Recirculation) cooler, which is used to cool recycled gases. The paste you can see, is a mixture of exhaust gas, soot & a coolant/water mix. This in turn was causing a blockage in the EGR system and causing the van to run poorly & in limp mode with the Engine Management Light lit.
