Hi, does anybody know the costs of replacing the timing chain, guides and tensioner on this model and does anybody recommend a good garage for this work to be done, I live in London near Heathrow.

I had mine done at Star Motors in Reading. I think from memory it was about £600 all in.

How did you diagonise the timing chain needs to be done?

Obviously,a check for the V belt.

Take a look on your records,when you last serviced
engine, if it is near due,do it.
