Fuel leaks on Volkswagen Group TSI petrol engines are more common than many owners realise, and they can be extremely dangerous if ignored. This fault can affect engines from 1.0 TSI right up to 2.0 TSI, across Volkswagen, Audi, SEAT, and Skoda models. In this post, I’ll explain the typical symptoms, why the leak happens, and what you should check before replacing parts. 🔥  Common Symptoms of a TSI Fuel Rail Leak A leaking fuel rail or injector supply line can cause: Strong petrol smell in the engine bay or cabin Rough running or misfires Hard starting Fuel stains or wet patches under the intake manifold Engine fault codes (especially misfire or fuel pressure related codes) Serious fire risk if fuel contacts hot components On many TSI engines, the fuel rail sits behind the intake manifold, so leaks are often hidden and missed during quick inspections. ⚠️  Why This Happens on VAG TSI Engines Common causes include: Failed fuel rail seal...

  The Ford 1.0 EcoBoost wet timing belt engine is well known for belt degradation, oil contamination, and expensive engine failures if problems are missed. To help owners and technicians understand what actually goes wrong and what to look for, I’ve put together a dedicated EcoBoost PDF guide based on real strip-downs and workshop experience. What This EcoBoost PDF Covers This PDF focuses on real-world issues, not generic theory. Inside you’ll find: How the EcoBoost wet belt system works Why belt material breaks down in engine oil Early warning signs and symptoms of belt failure What contamination does to the oil pickup and engine internals Inspection points most people miss When replacement is essential (and when it’s already too late) This guide is ideal whether you’re: Diagnosing a running issue Planning a timing belt replacement Assessing risk before major engine damage occurs Why EcoBoost Wet Belts Fail Like the PureTech engine, the EcoBoos...
