Timing belt and water pump?

[DMAC23]

Hi all, any advice when to get the timing belt and water pump changed??, currently on 69k milage  and I've read anywhere between 60k and 100k 

Rough estimate for the cost fitted??

Diesel or petrol?

Current advice is no time limit and 140k miles.  Changed middle of 2023.

If a TSI then if or when you change the Cambelt the water pump does not require replacing.    With a TDI it is best to.  As far as a 1.6 TDI or a 2.0 TDI I would be considering have I had the car from new and know how it has been driven.  How it has been possibly driven by others if bought used and how much you like to risk it for a biscuit.    Recommendations from VW group or others is OK but it is not them paying to have maintenance or failures.

On the back of my own comment and @Rooted's comments I certainly wouldn't be taking it any further than 100k.

Water pump and timing belt on opposite ends of the EA211 engine, so there never has been any need to change both together.

 

New guidance of 140k miles and no time limit for cambelt applies.

140k seems high, isn't it Russian Roulette, if it breaks the car is destroyed?

Not necessarily. Yes modern engines are interference design so the valves overlap into the space that the piston accommodates at top-dead-centre.  However I have seen some occasions of belts breaking and the engine just needing a new belt and timing done.  Often the head is designed to be a weak link so that a head rebuild can be done in the case of a timing belt failure.

I put 40k milage on the car last year, alot of motorway milage due to work, does that change anything with the timing belt? Alot of use in a short period 

[MarkyG82]

I have had that discussion a few times.  Partly due to me having a PHEV so the engine isn't always running.  My opinion is that transient revs (constant gear changes) puts a larger strain on the belt than a constant cruise.  High revs affect it too, so cruising in 4th or 5th compared to 6th or 7th would out more strain on the belt too.  Possibly even more than transient revs.  

To be clear, power output doesn't put a more strain on the timing system.  So remapping should have little affect to the belt and cams.  Valves may get hotter which introduces other issues but the belt itself should be fine.

 

In your case, high motorway miles, if driven normally, should be low wear and tear on the timing system.

For the 1.6TDI it was every 5 years and 100,00k which is about 60,000 miles. I don't have a copy of that schedule to hand, but I've deffo seen it.

Thanks for the advice, much appreciated 👍 might get it all done around 80k milage, frightened it all goes bang

Hi mate, I just spoke to Skoda Carlisle they have just said the timing belt is for life and doesn't need changing that's there new advice.  I'm not so sure 😕 

[Ootohere]

@DMAC23  was that someone on the service desk rather than a Technician.?    They are partly right.   When it breaks life is over for the timing belt and maybe the engine.   As of July 2023 the recommendations , guidelines , advice is not the time scale you were just told.  Others have in writing the time or distance and advice on checking, inspecting.

My 1.5 TSi is on 105k. I’m getting the timing belt done next month when i have the £1k that Skoda charge to get it done. 
 

Remember it needs a special timing tool (VAS 611 007) that only dealers and some specialists have so they charge through the nose.

I phoned Skoda direct and they told me it’s 5 years or 140k for the 1.5 TSI timing belt. 

[Ootohere]

Really.  I take it that was the Contractors that do Customer Services for Skoda / VW group who seem to give any old answer.   There are plenty threads here were members received written replies on the Guidance, recommendations or schedules on TSI cam belt changes that they issued end of June last year.
