Why is my Volkswagen Caddy diesel van losing power?

My 2015 Volkswagen Caddy 1.6-litre TDI is losing power. It starts fine and ticks over. Can you tell me what the problem may be?

There are a number of reasons why your Caddy van may lose power.

-Clogged air or fuel filter
-Blocked or faulty DPF
-Problems with the EGR (Exhaust Gas Recirculation) valves
-Faulty or damaged fuel injectors

The last one of this list is the most concerning, as it's a known weakness on this generation of the Caddy. It’s an expensive fix. Buy direct from Volkswagen and you’ll be looking at a bill anywhere from £2000-£3000 to replace them all.

If it is the injectors then it’s a false economy replacing a single one. Aftermarket, original equipment injectors can be sourced and will save you about a third over official parts, but it’s still a pricey fix should it need doing.
