The Problem
Power Loss Is Never One-Size-Fits-All
Loss of power is one of the most common symptoms mechanics see — and one of the most frequently misdiagnosed. The same feeling of sluggishness can come from completely different faults on different vehicles. What's wrong with a diesel SUV with 90,000 miles is very likely different to what's wrong with a petrol hatchback at 40,000.
⚠️
If your car has suddenly gone into limp mode — barely accelerating or stuck below 40mph — the engine is protecting itself. Continuing to drive in this state on a serious fault can cause expensive engine damage.
Why It Matters
Don't Guess — The Wrong Fix Costs More
⚠️ This symptom could mean several different things
🔧
Multiple different faults can produce identical power loss symptoms
🚗
Diesel and petrol vehicles have very different likely causes for the same symptom
💷
Repair costs range from under £50 to over £2,000 depending on the actual cause
⚠️
Limp mode means the engine is protecting itself — the wrong repair can make it worse
