2.0TDI - How often should the timing belt be replaced in TDI?

Every how many km/years. According to the manufacturer, 200,000, I understand that this is 1 replacement and then every 50, 60, 70, 80, 90, 100, 110, or 120,000?

Also 200,000 km

Which TDI are we talking about, from 1999, 2010 or maybe 2016? As for the tdi CR, it`s 200,000. but only on highway mileage, and 150,000 in mixed driving, but no one talks about it. 90,000 or every 5 years and it will be fine.

from 2017 to CR 150,000 with mixed driving, are you sure it`s not too much? The mechanic recommended 60,000 or even more

150,000 at the first replacement, and every 90,000 or every 5 years thereafter, but do as you see fit.

there are no guidelines, e.g. in the user manual, the manufacturer recommends replacement after 1 replacement every few km or something like that?

What kind of user manual, why should it be written there? The manufacturer stipulates that you should have your car serviced at an authorized VW service center, and they already know how often to replace the timing belt. As Piotrek Gti wrote, replace it every 90=100,000 and it will be fine.

I recently built an engine in which the customer never had time to replace the timing belt, at 220k km the teeth on the belt broke, the repair cost was PLN 12,000.

For these engines, the manufacturer`s recommendation
Timing: Belt, replaced after 180,000 km or 5 years

If someone wants, they can do it every year, but these are the recommendations, just like oil every 15,000 km or every year

In my opinion, the first one is PLN 150,000 for 5 years, the second one is PLN 90,000 and 5 years and the next one is PLN 60,000 and 5 years. The number of kilometers is reduced due to the wear of the wheels that are not replaced. And so the sum of these 3 replacements is 300,000 km, or more than the average of the vehicle`s mileage before it ends up in the scrapyard (rust).

To be precise, these engines (EA288) have two toothed belts, the second one drives the oil pump and works in the oil bath. When replacing the timing belt, remember to also replace it. More expensive timing kits contain the belt and cover with sealant and these are the ones you should buy

in EA188 was 1?

Timing every 60 thousand. km or 5 years and that`s it.

so why do you write earlier that every 150,000-200
or the manufacturer states 200?

I don`t write like that... What about the fact that the manufacturer provides such an interval? If someone likes risk, go ahead. The same with oil changes, the manufacturer states every 30,000 km, I change it every 10,000 km.

I understand, so I`m asking how often, because you can even do the timing belt every 30,000, but why?
so I`m asking what 45,50,60,70,80,90,100,120? so 60,000 or 5 years, right? I heard they also say every 90

man12124, it`s best to check what the manufacturer provides, I provided the rest in my post.

Do you have a service book for this car or not? there you have the exchange intervals...

I haven`t seen any manufacturer recommend replacing the timing belt every 60,000 in a diesel engine, most of them do 30 thousand per year, so replacing the timing belt every 2 years?

You can assume that you change the timing belt every 5 years and the oil every year and that`s it.
You can sleep soundly.

probably every 90kkt

Manufacturers tend to extend the duration of service visits during the warranty period. Apparently, such an inspection costs money and the costs are covered by the guarantor. So they extend this time as much as possible. If even 2 or 3 cars need to be repaired under warranty for this reason, they are still ahead of the curve and a specific number of mechanic`s hours and spare parts/operating fluids are required. It is simply profitable for them and what impact it will have on the condition of the car after the warranty is not their problem. That`s why we have Loglife oils and filters (1 replacement instead of 2 or 3). The first timing belt is expected to last the entire warranty period. The next one is not their problem.

Therefore, sometimes it happened that with each subsequent replacement, the number of kilometers from replacement to replacement of the timing belt was shortened...

Oils are a slightly different story, changing them every 30,000 or recommending not to change the oil in the gearbox is, from what I once heard, the result of "ecological" regulations...

Shortening the intervals on the timing belt is justified by the fact that we change the belt but the wheels remain old. They wear out and destroy the belt faster. The first two belts come from the factory and you can`t necessarily buy them in the quality and control that these belts go through in the factory that assembles the engine. Another aspect is the time from the production of the belt to its installation/use.

sigwa18, so are you suggesting that, for example, the Contitech/Continental belt is much worse than the ori from the factory? Well, I don`t know, because this particular company, for example in tires, is number 1 in my opinion
on the other hand, you don`t pour the same oil as in the factory, but aftermarket oil, how do you know how the engine will wear? What "quality" does he have?

Well, the client certainly does not test one strip from a batch of, for example, 1000 in his own laboratory. The power of negotiation is two different. If you want a belt with specific parameters, they will laugh at you. How the factory orders is a different conversation. Look at the batteries, they seem to be the same manufacturer and have the same capacity, but the stickers are different. However, those from the first installation are heavier and last much longer.

Oil and lubrication systems in general have been a circus in recent years, and I dare say that combustion numbers and emission standards are much higher on the list of priorities than engine durability (of course, after the warranty, and even this varies). Such as 0W20 oil. Variable displacement oil pumps. Turning off the water pump etc etc. and general road testing of systems and solutions on customers. Software patches that fix one problem and create three new problems.

Unfortunately, the customer looks at the car differently and the factory looks at it differently.

but for the first assembly, the factory does not produce VW parts, only some other company
so you`re saying that you can`t buy the same part as for the first assembly and the original one at the dealership?

My Skoda SuperB 2.0 tdi CR 170 HP from 2012 (CFGB engine) had a ContiTECH timing belt with an additional VW logo from new. I bought a new one at the dealership, also ContiTECH, and the VW logo was also painted on it. The car has been in the family since new, so I`m sure it hasn`t been replaced before.

Belts or other parts available at the dealership - it is known that they are not produced by, for example, VW or Audi, but by other companies - subcontractors, e.g. Contitech or other companies, but these parts are subject to much more restrictive quality standards than the same part available in a wholesaler or automotive store (without VW logo, etc.) and therefore must be made even better - quality 1A.

This is where classic quality management comes in. The client does not have a laboratory and if something goes wrong, the consequences are the loss of the client. It is difficult for the customer to prove that the supplier did something wrong. The factory is now a legal department, a laboratory, and tests. Threat of breaking off contact or contractual penalties.
But is it worth 2.3 times as much, when sometimes it is the same production line and the part differs with a milled brand logo.

If anyone is wondering what the timing issue is on new 2.0 TDI engines (DTTC designation in my case, Seat Leon IV, 150 hp, vintage 2021), I can share my experience. A few days ago I replaced the timing gear at 200,000 km. The manufacturer recommends replacement after 210,000 km, but I preferred to blow the whistle. After this mileage, the timing gear was in perfect condition - the rollers were not worn and the belt had no cracks, only a little dirt. The mechanic couldn't believe that the timing gear hadn't been replaced before. Personally, I wouldn't wait longer than 200,000 km, but if someone is thinking of replacing it at 100,000 km, it doesn't make much sense in my opinion. I hope I have been able to help someone. I would like to add that the car was imported from Germany, mileage mostly highway.

Call an authorised service centre and they will tell you, only Volkswagen.

The recommended timing change intervals for the 2.0TDI engine depend on the manufacturer and vehicle specification. In general, it is recommended to replace the timing gear every 180,000 km
