Volkswagen Multivan Problems

First suspicion would be that the fuel injectors need either reconditioning or replacing. Rough running, hard starting and excess black smoke are all classic symptoms of worn injectors. That said, the modern turbo-diesel is a pretty complex animal, and you could also have a problem with the emissions system (EGR valve) or maybe a build-up of soot and oil in the intake system (which could also affect any number of sensors around the engine).

Don’t forget the basics, either; something as simple as a dirty air-filter element can also cause problems just like the ones you’re having.

If you are not sure get another opinion. That would probably mean having it trucked to another location, but that’s the best thing to do to make sure the advice you are getting is correct.

I would get a second opinion on the Kia's engine before you do anything else. A sludged-up engine suggests a lack of servicing, but if no damage has occurred you might be able to salvage it. I wouldn't recommend either a Multivan or Valente, those you are looking at are too old and potentially too expensive to run and repair. A seven-seat SUV might be a better option.

You can start by having the dealer explain what they are doing to try and fix your car. If they cannot provide a satisfactory story on their plan to sort the problem out, ask them to call in experts form VW head office to assist them. If that doesn't work out get the advice of the consumer affairs department in Perth. Talk to a lawyer if things don't appear to be improving.

From my experience, the Grand Vitara has the best reputation for reliability and for you it ticks the boxes. Next would be the Honda CR-V, then the Dualis with the ASX definitely last.

Don’t judge the Carnival by the badge, as it definitely gets The Tick. The The Multivan is also far more practical than any SUV, as you will find when you try to load all the stuff that comes with four youngsters. If you absolutely must play the SUV game, go for a Hyundai Santa Fe, also a Tick winner.

The Multivan has been around for a number of years now and it doesn’t appear to suffer any particularly serious problems.
