I'm looking at doing my cambelt and waterpump on my 2015 2.0 tdi q3 quattro. Looking at the parts needed ive noticed some waterpumps have toothed pulleys and some have flat also some have plastic fins and some are metal. Can anyone give me any pointers on which is best to buy thanks

Welcome Stephen and thanks for joining. 
My initial broad  brush response to your question is that  the choice sounds untypical, and I believe it shouldn’t be an either/or situation. I could well be wrong, but…..

Could you let us know where you are searching in respect to obtaining parts, and what brands are you considering buying.

Regards,

Gareth. 

 

Thanks for the reply ive been looking on Gsf and autodoc these are the Ina and Gates ones as you can see they're different but both fit my vehicle 

It seems totally illogical that both toothed and non toothed water pumps are alternatives for one another.

A couple or so hopefully helpful tips for you:- 

Study LLL Parts website  in relation to your car, and get the correct part number.

Put your reg. no. into Parts in Motion website and see what specific information you get from there. If doubt still exists, phone them ( don’t  EBay message them) armed with the part number and discuss it with them - they are usually very helpful. 
Why Autodoc and their postage rates? Also seldom found GSF to be generally that competitive.

Please let us know how you get on.

How are you getting on with this Steven? 

I found that my vehicle had a switchable waterpump so mine is the one in the second pic I think the one in the first pic was for the euro 5 engine 

Thanks for updating the forum Steven.
