Timing belts or chains?!


I was a bit concerned to read in an online article that the timing chain on a three-year-old Volvo V60 (just outside warranty) broke and destroyed the engine (and until the newspaper got involved Volvo was going to make the owner pay for the new engine). The article also said that they were noticing an increase in timing chains breaking. Surely the whole point of a chain vs belt was that it would last. Better off with a belt and changing it at 150,000km. Costly, but, perhaps unthinkable, more secure??

Having been very taken with your recent review of the V60, I'm reconsidering going back to a Skoda, but unfortunately, the same article said that the Volkswagen Group were suffering particularly from broken chains. Does the Superb diesel have a chain or belt? Do all cars now have timing chains?

Should I clean or replace the EGR valve?

My garage has told me that the emissions light on my dashboard is due to a fault in the EGR system. However, the car is running fine with no loss of power. The emissions light is not consistently on, only occasionally in the last week. Should I get the valve cleaned first as my garage are quoting me €500 for a new part plus labour costs?

Thank you.

Diesel still best for high mileage?

So with so many car makers planning to phase out diesel engine options in 2019, what are the real options for high mileage drivers? Will there be big impacts on residual values for diesel cars purchased later this year? I drive about 40,000km a year and need to change later this year.
