SEAT Leon ST - Dealer vs independant cambelt replacement - Tripspace

Hi all,

New to the forum and hoping someone can give some advice please ??

I have a Seat Leon 2018, that has just turned 5 and I'm told I need to replace the cambelt.

I'm thinking I will sell in the next 2 years, and the dealer is offering a 5 year warranty on the cambelt for £560, but my local who hasnt let me down is offering for £339 with a 12 month warranty.

Given the seriousness of that component I'm not sure which to choose, given I'll likely upgrade in the next year Would it be better to go to the dealer? I don't really want to waste £220 if they'd do just as good a job. Not sure if peace of mind is the 5 year warranty if it goes horribly wrong and a mistake is made.

Can trust the local, but I've only ever used them for anything that's not the engine. Give its the first newest car I've ever bought, I've got the fear a bit. Then again if the overall car is out of warranty is it a waste going to the dealer?

I'm really keen to decide tomorrow / early next week so any help and advice much appreciated :)

Thanks in advance

P.s. I have googled a lot, but didn't really answer specific questions :)

I face the same dilemma later this year with my 2018 Golf. There is a third option, a VAG specialist. In my case a local one has a special offer for £299. Or you could go to a cambelt specialist. Yet more decisions.

You could see if the dealer will price match.

In my case I will probably use my excellent indie. He is a generalist but does specifically have the VAG diagnosis tools. Reading up it seems these later engines have a requirement for some mysterious tool to set the belt up. I am not sure what this is and whether it’s true or not but someone more technically minded may comment.

Finally I doubt whether main dealer services makes much difference if you are trading in what will be a seven year old car. Last time, trading in my Civic, the VW dealer just checked it had a stamp for each year. Who did it was immaterial.

I wouldn't pay a great deal of attention to the warranty. If it's done correctly, it will last 5 years. The only important bit is whether the indy has the equipment needed to set your timing properly (I assume it's a TSI engine). I suppose you could just ask the question.

Many of the later Vag engines require a specific electronic gauge to enable the cambelt timing to be set up accurately. If it’s not used , then it’s likely the engine will not run smoothly. The kit is massively expensive, about £2k , so not many Indy garages will have it .

This is the second thread I have seen about advice to change a cambelt when only five years old. Why is this? Modern cambelts should last the life of the car. Is this a peculiarly UK garage 'workshop filler' advice? I have seen others say the advice is different in mainland Europe for what is basically the same engine. Is there a design flaw in this particular engine that somehow compromises the integrity of the cambelt? I find it hard to believe the manufacturer would design an engine with such an expensive maintenance item occurring so early in its life. Ford designed a cambelt for life for its Focus 1.6 Zetec engine in the last century, although they did advise a cautious precautionary change at 10yrs and 100,000 miles. I ignored it and our Focus went to the scrapyard at 21yrs old and 162,000 miles with its original cambelt intact. I would have thought VW could have matched this by now.

I tend to side with John. Cambelts don't deteriorate much with age, more with how much stressful work they have done. So IMHO the miles on the clock is more important than the 5 years. We haven't been told that ?

And main dealers have been known to mess up a cambelt change, as well as independents. Maybe if it ain't broke, leave well alone. On the minus side a recent cambelt change would make your car easier to sell later.

When we bought our Leon in 2013 the 1.4 TSi engine was a new introduction and the Seat dealers had little info. However, the VW Golf brochure had a full page on how the new engine had a special Conti belt that was designed for the life of the car, no need to change. Same engine in the Golf and Leon so considering I expected to keep the car 5 years max no change would be needed.

Car went in for first service after a year and on the Seat dealers wall was a menu price to replace the cambelt with a time/distance recommendation of 3 years/30,000 miles. When I got home I looked on the Seat website and there was nothing about changing the cambelt whatsoever so I contacted them. Got an e-mail back confirming the interval was check annually after 60,000 miles but regardless of mileage change at 6 years or 120,000 miles. Very different to the menu at the dealer, never went back there.

I have had 2 x 2.0 Zetecs in the Caterham, the first was a well used early Mondeo one, the 2nd a brand new late Mk1 Focus one. I swapped the Mondeo belt before I fitted the engine in the car, no idea of mileage plus I needed to change the water pump to a different impeller type and that required the belt removing. No idea of the mileage (car was written off due to dash fire), the belt was clearly worn but not cracked.

Since Ford recommends 10 years/100,000 miles I replaced the belt on the Focus engine when it was 10 years old. I had done under 20,000 miles and expected looked pretty much new but there was a hidden surprise. The tensioner bearing was pretty much knackered, had it failed it could well have trashed the engine.

The 10 year anniversary is next spring, rest assured I will be spending the £150 or so +1/2 a day in the garage to repeat the exercise. Only £15 a year, on average probably spend that much a week on coffees.

As for the Fabia, its 5 in April but with its low miles I see no need to change it just yet, we will probably sell it before its needed. A quick visual before the service might be a good idea.

"The tensioner bearing was pretty much knackered"

This subject seem to pop up quite often and that's exactly my concern. I have no doubt a quality OEM belt will last a very long time but what tensions it may not.

But the same argument applies - the tensioner fails because of use, not the passage of time, so your decision should depend on accumulated mileage ?

SEAT Leon ST - Dealer vs independant cambelt replacement - Gibbo_Wirral

5 year warranty is nice, but will it be transferrable to the new owner?

If not, then pointless if you're selling

As a buyer, just the evidence its been done professionally would tick my boxes.

SEAT Leon ST - Dealer vs independant cambelt replacement - catsdad

I agree that the VW U.K. schedule is too pessimistic mechanically. However my rationale in getting it done around the five year mark is that I intend to keep the car for another five years and over 100k miles. In that case one change in ten years is not excessive. It also stops the “do I feel lucky?” nagging doubt as the years tick by.
Even if my next car buying itch kicks in before then the lack of a belt change would likely depress the trade in value if I didn’t have it done. As others have indicted, even at dealer prices it’s not a lot over the life of a car.

The tensioner in the Caterham had been in the same time (10 years) and distance (20,000 miles) as the belt. If I had simply changed the belt I would almost certainly have had a very big bill some years ago. The tensioner only added about £30 to the parts bill (Ford do not do full kits) and fitting it was one bolt out and new bolt in (its in the box with the tensioner), 2 minutes at most.

I also replaced the guide pulley, it felt fine but after spotting the tensioner issue I was a bit nervous.

Next year I will buy a Conti kit.

I think a failing tensioner pulley bearing would usually give a warning to a mechanically sympathetic driver.

Back in the 1990s our family VW Passat 2.0 GL estate was doing a high mileage and I noticed the typical screech of a stiff bearing - around 130,000 miles IIRC. I was able to change it easily before it fried the cambelt, but changing the belt itself was beyond my competence and as the car was needed every day I left it alone as it looked fine. It had over 240,000 on the clock when we traded it in for a 3yr old Focus estate in 2004 - no further belt problems. I wouldn't worry, Xileno - my son scrapped that Focus at 21yrs old and over 160,000m, still with its original belt and tensioner pulley.

I'm sorry to have to say this John but what on earth do you know about mechanical sympathy. You openly admit that you rarely change your oil, never change you cam belt, brake fluid and antifreeze and once suggested that changing just one brake pad at a time made sense if the others still had life.

I can 100% assure you I had not heard any warning noises prior to removing the cam belt. It was not stiff but there was a large amount of sideways play. The replacement was just as a bearing should be.

That's because it takes a long time for the engine to do 6000 miles (TR7) and 10,000 miles (Audi). I do not subscribe to the belief that oil in what these days is virtually a sealed container 'goes off' with the mere passage of time.

......and once suggested that changing just one brake pad at a time made sense if the others still had life.

This extreme economy thought occurred to me when changing the pads on my DIL's Acura. They were all the same shape, so could go either side of the disc. Seemed a good design to me. In theory, there is no good reason why not to do this if plenty of time to spare to get maximum VFM from your pads. Indeed, you could argue that if only one new pad needed the initial gentle 'braking in', an emergency stop would be less likely to be compromised as only one pad would not be completely bedded in - assuming the disc had not been renewed. Anyway, I'm sure you will be relieved to know that all three very worn front pads and one backplate were renewed, and the mechanically unsympathetic DIL was pleased that the nasty scraping noise (from the naked pad-less back plate :-( disappeared.

That has been the case for every set of pads I have fitted since 1975 (Triumph Herald).

But its always been the accepted wisdom that since they should be wearing at exactly the same rate all 4 pads on an axle should be changed together especially when you can only buy them in axle sets.

No doubt these days someone on E-bay will offer them for sale singly .... :-)

Probably John after he has used 1 out of the 4 he bought.

BUT if one pad is worn more than the others,(assuming previous owners are "accepted wisdom" afficionados) there';s something wrong with the others, which does happen "accepted wisdom" notwithstanding. Once you''ve fixed that, if you've got an odd pad to replace the most worn one, I can't see much wrong with doing so.

Can't remember doing it with pads but I have definately done it when replacing failed brake shoes, with no obvious dire consequences.

None of which has much to do with sensitivity to unpleasant screeching noises, which was the context.

SEAT Leon ST - Dealer vs independant cambelt replacement - Xileno

To me it falls into the 'why bother' bucket. People will - and do - argue over this issue but to me, if one pad is more worn then something is wrong, probably a sicking caliper. So while it's all stripped down and that problem sorted, just put some new pads in. How much are pads? I can't remember the last set I bought but they have never been expensive. Then you know everything's all good for x thousand miles.

But none of this side discussion is relevant to the OP so can we now return to that please (if there's anything further to add)

Last I bought were a set for the front of the Caterham. EBC Ultimax 2 which originate on the front of a Volvo 240, £14 the set.
