Hi all

I should be picking up a 2002 Audi TT Mk1 later this week (180bhp quattro) with full service history but the timing belt and water pump were done just over 5 years and 20,000 miles ago and reading on here and elsewhere it seems I need to get these done again ASAP yeah?

If so can anyone let me know if there's a particular belt and / or water pump kit that's recommended as I read there was some pros and cons between the metal and plastic water pumps?

Finally what 'stretch bolts' do I also need for the job as I read you probably need these too?

Many thanks all [smiley=thumbsup.gif]

NOTE: I know everyone will say I should have got the 225bhp BAM one BUT I am coming from a crap Citroen C4 Grand Picasso so this will feel like a Ferrari to me for a while at least :p

Hi, Welcome to the TTF.
If this is not DIY then let the garage supply the parts, otherwise I would use OEM parts, but Gates appear to be popular & could even be OEM parts. OEM water pumps are still "plastic" but improved from the original.
Make sure you replace the hydraulic damper as well, it's not supplied with the OEM kits.
The stretch bolts are for the engine mounts & should be replaced.
Hoggy. :D

Thanks both for those helpful replies.

I'm going to be letting a local garage do the work but want to pass on the information from here so I get everything that's recommended done at the same time in case they miss anything.

These are the right bolts yeah?

Thanks
Hi, Yes, looks correct.
Hoggy. :D

INA supply the idlers and tensioners for VAG, so I'd like to think the belt in their kit is OEM too.

You want an OEM water pump preferably, the metal impellers can fail the bearings early, that's from a reliable source.

I've fitted Dayco without issues in the past too, but I mainly fit INA kits now, I have one for a TT currently iirc.

ÂŁ111.79 for the INA kit via https://www.autodoc.co.uk/ina/7277818 - that seem about right?

Might be worth getting the garage to price up genuine VAG parts.
When I had the Timing belt on my A4 changed they used VAG parts as the kit was only a tenner more.
Cheers will ask the garage what they think as they are friends of mine and knowledgeable with VW stuff

Did this job a few weeks ago , for my TT in similar circumstances , only 7K miles but 8 years since the last cam belt change .
I went for a Gates kit , as in the UK Gates belts come with some of the Genuine kits .
Complete kit with belt , tensioner pulley, hydraulic damper and water pump was just under ÂŁ100.
Even though I had the Gates pump on hand I decided to fit a Genuine pump , as has been said they have still have plastic impellers but appear to be sorted now.
You have to be very careful with the engine mount bolts, the large bolts screw into an aluminium mount (which in turn is bolted to the engine block) and it is this torque figure that many people believe the official Audi figure is incorrect i.e far too high.
So high , that many find the thread stripping out of the aluminium mount , before the bolts ever start to stretch.
Look on this forum as there has been much discussion in the past about it, IIRC I did mine up to about 60lbs/ft , with no issues .
The smaller bolts screw into a steel captive thread and these you can torque up to the official Audi figure.
I don't know why the eBay link shows 5 bolts , you only need 4, 2 large and 2 small?
These are the bolts I purchased.......and a pic of the engine mount off my car with the new bolts ready .

This is what I was quoted from my local dealer (excluding VAT). Parts are for a 225, not sure if they're the same as the 180 but someone will know. :D
Sam.
What's the belt dampner for over ÂŁ100 :?:

Will be interesting to see the water pump comparison too @Amulet banana

Yes that is a good price. My mate can usually get VAG prices at trade discount for me etc but he can't get me a price until tomorrow so not sure whether to get this and then he can just get the others bits :?

That's brilliant value.
The same kit I used , can totally recommend it .

Cheers for alerting me and others to that deal!

I have ordered that eBay one for that price as I can send it back if my guy says it's not worth using as he did mention something about the VAG one coming with everything together but I'm sure he won't mind using that one.

Ive just been quoted ÂŁ399 all inc with my local indy using VAG oem parts.......so which kit is better....Gates or VAG??
Does this include the hydraulic damper?
They aren't normally included in the Genuine kits, and really need to be replaced each time the belt is done .
Gates are OEM suppliers , at least in the UK.
This is the damper .....the leaking factory one that came out of my car when I did this job last month :eek: .

The Genuine price for the damper is around ÂŁ100 (a crazy price :eek: ) , the Gates kits (amongst others ) include this.
Really recommend changing it , if that damper fails then bye bye engine, it's this damper that applies tension to the tensioner pulley.....
My car has done 64K miles from new and previously had a belt change in 2012 at 57K miles , when I did the job last month I found a good quality cam belt on there (Contitech) that looked as new but the 2003 damper was still there , and leaking :eek: .
Many garages don't replace the damper as a matter of course .
IMHO it's false economy not to replace it.

Kit on Ebay includes damper going from the picture and item description.
It does include the damper , that's why it's such good value .
Like I said , that's the kit I used (although I did use a Genuine water pump instead of the supplied Gates one) and it fitted perfectly .

Some of the buyers of this kit wrote in the review that it was delivered with a plastic water pump propeller, not with a metal propeller as shown on the photo
