You have a thread open on this subject already.

If you bought it from a dealer, it's down to them to fix it.

If you haven't done it already, go to other VW forums and ask the same question.

This doesn't apply to a Columbus system

If it's a Columbus system it doesn't need an SD card for the sat nav to work. The data is stored on its internal memory. Any SD card of a suitable size will work to transfer the data. Are you sure it's a Columbus, as you mention a Skoda SD card of 7gb in your first post?

I think it's sealed for life but I stand to be corrected.

How many miles?

What's the trick?

Does it work in the unlocked position when it's in the car?

Same. Mines never creaked.

Post a screenshot of the version and software no's and somebody should be able to help you.

Assuming you have the Amundsen system, this thread should help you. See the 8th post from aki78.

Mine has just done the same thing. Coil light flashing and s/s not working. This was during a 200 mile trip of mainly motorway and A roads. Was still flashing when I reached home. No loss of performance. Was not used for a month and then had a 150 mile trip, 80% of it on the motorway. No faults at all but average fuel consumption down by 8 / 10 mpg. Could this be a sign of the egr failing?

So in this case, if you were the OP, you would negotiate a deal on a car knowing it had a faulty DPF but the price you paid reflected this. After purchase would you then expect the garage to replace the DPF at their expense and if not use the Consumer Rights Act?

D. Get a car with an engine suitable for your type of motoring.

I'm a bit confused. How did you know it hadn't regenerated for a while?

Do you mean they have refunded you £800?

I'm guessing the water pump belt has a lot less stress on it compared to a timing belt. If the pump failed at an early age it may not be neccessary to replace the belt, hence it being sold separately.

That's why I asked what engine the OP has.

If it's firing up straight away it would seem they're ok.

What engine do you have?
