Disadvantages of the B4184S11 engine
- The main problems are floating revolutions, which are difficult to get rid of.
- The culprits are usually the electronic throttle or intake swirl flaps.
- Also, lubricant consumption is often found here due to the occurrence of oil scraper rings.
- From low-quality gasoline, the fuel pump or fuel pressure regulator often fails.
- Closer to 200,000 km, the timing chain and phase shifter may already require replacement.
I have the B481S11 chain driven petrol engine in my Volvo V50 and I have found it so reliable. It’s never broken down in the 9 years I’ve had my car and I bought it with 75k miles on the clock. It’s now done 122k. It gives plenty of punch for a 1.8ltr. Change the oil/filter regularly every 6k.
