My vw dealer have stated that my mk6 2.0 tdi is due a cambelt change and water pump aso i think. Its 5 years old in march 2017 and has 48000 miles on it. Am i having my pants pulled down or should i get it done? Doubt ill go to the dealer as ive a specialist garage nearby to keep costs down.
Thoughts??

My 07 mk5 said 100k in the handbook but when I got it late 2010 and checked round (dealers and independents) I was told VW had changed it to 80k or 4 years in a service bulletin and AFAIK that time interval is still in play so that's likely why they are saying it needs changing.

FWIW my local trusted independent (the owner who has had it 30+ years) told me that Vw had said the time criteria was somthing to do with degradation of the belt material in certain environmental conditions like high ozone etc.

When I pushed him for his opinion he said he had never seen a within mileage belt fail unless there were a mechanical reason and that tbe time could be ignored

I followed his advice and eventually changed the original factory belt at 78.5k (was taking car to Europe) and 8.5YO. It was in pristine condition

Sugest you get in touch with Vw UK HQ and ask for clarification on the current. The mk6 is after all largely a Mk5 with a make over rather than a new design

agree with gerrywak post , see how much your local garage is charging and have a think . my friends Audi belt snapped as he was going on holiday just left the house wrecked the top half of the engine had to have it rebuilt  so they do go, if its reasonable price and your keeping the car might be worth it for peace of mind

I just see it as a cost versus potential cost. If it goes you'll kick yourself as you fork out thousands for a new engine, better to spend a few hundred to keep it covered. Shop around for prices though I am lucky as we have an 'old boy' mechanic in the next village so belt and pump changed for £200. From VW you'll be looking at £400 I'd think so have a look around.

I'm still a  bit scepticl about the 4yr malarkey but as a newer car it's maybe worth it to keep up the service history (if the 4 year is still in force)

 

There seems to be no shortage of independents who will do  full change and water pump for around £300 and quite a few VW dealers seem to offer price matches if you get a quote so worth asking if that VW stamp is important.

 

It's worth pointing out that the VW service recommendation is "belt only" the tensioner and idler are every second belt and the water pump is never a service item (replace when faulty).

 

The reason that full changes are quite popular is that there is very little labour cost in fitting a tensioner and new pump whilst doing a belt and the parts cost is relatively modest. The extra is certainly a lot less than doing either job months or years down the line as a stand alone job so for some it's like cheap insurance.

 

I suppose it depends on how lucky you feel, I didn't change the tensioner or the water pump on my 07 Golf just the belt at just under 80k

The pump still has the same hours on it that the belt, tensioner and other components do.  Bearings fail; so you'd be daft not to do the pump.

Any mechanical part can fail unexpectedly  but wear items aside it isn't generally the case they be routinely replaced without reason either by design life or following inspection.The fact is that if the pump were particularly liable to failure and degradation then VW (and other car makers) would make replacing it part of the service regime and AFAIK nobody has done that (at least in the 40 odd years I've messed with cars)

 

Looking back it appears to me that the VW water pump "problem"seems to go back to when they introduced plastic impellers and experienced quite a rates of failures with the original batches. The problem was quickly resolved by changing the plastic used but the stories still perpetuate in the forums and many  people seem to try and get metal impeller pumps rather than plastic.thinking them superior.

 

Having become aware of a problem from research after buying my Golf and planning servicing and maintenance. I did discuss this with the owner of my local Independent (along with belt change intervals) whose experience I trust  and he said his experiences over many years did not justify routine changes.

 

Caution is not a bad thing but replacing car parts for that reason alone can work out expensive, it is better a case of considering the facts and exercising judgement and I wouldn't criticise anyone  for deciding to  have a pump change done.

The bearings wear.  Why do people replace the tensioner then?  The idler?  Wouldn't be me.

I just had a new cam belt and water pump last week (don't know if they did the tensioner or not).

My golf is 2.0 TDI, late 2001, 52k miles.

The garage is VW main dealer, and I went there becuase the car is still new (18 months) to me, so I want to treat it for the first few years.

Cost was a whopping 470 or there abouts.

 

I paid £737 for cam belt water pump, minor service and MoT.

Much to my discust they included a brake fluid change which they recommend every year or (2 years perhaps).

 

When I've had the car a bit longer I'll stop going there!

Never been a big  fan of main dealers, too expensive and they also charge a packet for scans etc. Bought my 07 1.9TDI six years ago (to the day today :D ) one owner fleet car with FSH. A couple of months in had the infamous ABS pump failure and a lot of aggro with the main dealer and VW over the extended warranty repair

 

First thing I did after was find a decent local Independent VAG specialist for advice and discount MOT's. It's a bit of a joke with him as the only work he's had was a scan before I got VCDS but he gets my MOT every year. I did discuss belt with him a year ago £300 but I ended up doing it myself

 

Recommended change interval for fluid is 3 years from new and every 2 thereafter. Brake fluid absorbs water from the air which can create corrosion problems in the Callipers if left (and potential loss of brakes under prolonged hard braking) which is expensive to remedy.

 

Best get it changed regularly (if not 2 years not too much longer) to keep the hydrauilic system tip-top

I was told by the VW Dealer Service Manager when I bought my Golf that VW UK  recommend every 5 years or 140k ....though only the 140k applies outside the UK with no recommended change due based on time scale.

 

Not sure what to do myself at 6 years old and 30k.....belts look in good condition too.

The VW Elsawin service manual doesn't show a time interval anywhere for the 2.0 CR diesels in the Mk6 as you say this appears to be something issued by VW in the UK

All up to 2009 model year are shown as 120k miles with the tensioner at 240for MY 2010 this altered to 140k for both belt and tensioner

On my Mk5 I got it at 3.5yo and checked the belt change with VW and they gave me 80k(100kin manual) and 4 years. I discussed it with my old school independent and he suggested the 80k was ok but the time interval was bunk (far too short) so I followed his advice and finally changed at 8.5yo just shy of 80k
