Good evening, I'm hoping that someone can guide me to the right purchase?

I recently bought my wife a very nive but older A6, 2.0 tdi Avant.

Full service history but no evidance of cambelt service. Its done 96k.

The dealer has said this needs attention and his mechanic says he will bill me for his time only if i supply the kit.

Been on many sites but its a minefield of brands and I'm lost

He said you should probably change the water pump at the same time.

On europarts I can find a cambelt kit for about £150 but not sure what water pump to get. Here is the link to the cambelt kit

Is this the correct part, is this what I should expect to pay?

Someone here must have gone down this route before and be able to offer some advice please?

Hello Simon, 

Without wishing to appear patronising, I think you are very wise to question when the belt should be changed, and particularly what parts to use. Owners sometimes fall into the trap of simply looking for parts as cheaply as possible for this most critical application. 

100% peace of mind? Use genuine VAG parts but be careful about buying on line where belts may be aged stock and you could be buying a belt already older than  it’s time limit change! If you are not using VAG parts then the only aftermarket kit I would buy would be Gates - no exceptions in my book. They are a volume supplier to many motor manufacturers. But, and a big and most important but, I would not use their kit which includes the water pump. 

Water pump? Yes change it, but I would never (in caps) use any aftermarket  pump - only a main dealer one. No exceptions. You will probably have to pay a surcharge until you return the old unit, but as I understand it, the logic is that it removes old pumps from the substandard reconditioning chain. 

ECP? Any particular reason why?  Seldom the cheapest even with their discount codes. There are many others, but again beware of aged stock.  

Hope some of this helps, 

Kind regards, 

Gareth.
