1.9L TDI VW Timing Belt Replacement Info BEW Engine

Everything you need to know about VW timing belt replacement on 1.9 liter TDI engine with BEW engine code; which was used in the following Volkswagen models:

  • 2004-2005 VW Jetta A4 chassis (aka Mark IV)
  • 2004-2006 VW Golf A4 chassis (aka Mark IV)
  • 2004-2008 VW Beetle A4 chassis (aka Mark IV)

Note: There are two different engine codes in 2004. ALH and the BEW. VW owners with model year 2004 should confirm their engine code.

The BEW TDI engine is driven by a timing belt system which links the cylinder head, camshaft, injection pump, and crankshaft to run in sync. This VW timing belt system consists of a wear resistant, high strength, corded/molded rubber timing belt (a.k.a. VW toothed belt). There's also an assortment of tensioners and idler rollers to guide and tension the BEW TDI timing belt.

It's very important to service your BEW VW TDI timing belt. The timing belt, tensioner, and idler components eventually reach the end of their recommended service life. The BEW engine code TDI is an interference engine (a.k.a. non-clearance engine). If the VW timing belt fails, the timing belt system that links the cylinder head, camshaft, and crankshaft no longer run in sync. Close tolerance engine designs allow for the cylinder head valves to hit the top side of the pistons. VW timing belt failure on these engines will results in catastrophic engine damage (i.e. bent valves and in some cases cracked pistons).

VW Timing Belt Service Change Interval

BEW VW TDI Timing Belt Change IntervalWhat is the recommended timing belt change interval for A4 platform VW Jetta Golf Beetle 1.9 TDI BEW models?

The most recent recommend interval is 80,000 miles for the VW BEW TDI (a.k.a. Pumpe Duse Injection BEW TDI).

Using our years of service repair knowledge, what do we recommend? When dealing with crucial timing belt service, err on the side of caution and change your VW Jetta Golf Beetle BEW TDI timing belt every 80,000 miles as is recommends. It is our recommendation to closely inspect all timing belt components before the recommended interval. Play it safe, changing your timing belt may seem expensive. However, choosing to exceed your timing belt service interval is risky and can lead to unknown repair costs that will far exceed typical timing belt replacement service cost.

Intended Life-Expectancy of Timing Belt Components

BEW VW TDI Timing Belt Part Life ExpectancyIn our own service facility, we've seen a few original timing belts last over 90,000 miles and others ready to break before 75,000 miles. In addition to mileage there are other factors that age the timing belt and related components. The following are some reasons why you see the difference in how long a VW timing belt and related components last: (1) un-logged engine idle times and sitting in traffic; (2) warm-up time in cold weather; (3) environmental climate factors; (4) related engine maintenance that may have been overlooked.

Keys to the long-life of your new timing belt components after timing belt replacement. Make your new parts last! You can expect your new BLAU INA OEM components to last the specified 80,000 mile interval if the following important steps were taken:

1) Timing belt service was performed using the same timing belt and timing belt tensioner that are supplied to VAG, which are engineered to meet the specified change interval requirements.

2) Timing belt service was performed by an experienced competent ASE certified VW mechanic who is familiar with your specific engine 1.9 TDI BEW engine.

3) Factory service procedures must be strictly followed. Even if installing the best parts, using improper procedures can shorten their life span. Incorrect installation or missteps during timing belt service are often done without intent and aren't noticed until further down the road. Fortunately, some common mishaps are noticed after re-assembly and during the final engine rotational timing sequences.

The average timing belt service labor time for this engine is around 6-8 hours depending on the technician's experience and the amount of timing belt parts being replaced.

How Much Does It Cost?

1.9 TDI VW Jetta Timing Belt Labor CostThe average shop labor rate is $75 - $200 per hour. The lesser amount is often found in smaller cities and the more expensive labor rate seems to align itself with larger cites. Depending on shop rate, technicians experience, and the amount of VW timing belt parts being replaced it can cost approximately $600 - $1,600. This is just the labor cost (not including parts).

How Much Do The Parts Cost?

It depends. Some choose to source the parts themselves, while others get the parts through their repair shop. Some repair shops prefer to supply the parts themselves. This allows for cost margins and potential profits on the parts. Also, they can control the type of parts used, reducing the potential problem of having customers come back with part issues.

Looking to Buy a Used VW TDI and Wondering About Timing Belt Replacement?

Many people who are looking to buy a used VW Jetta Golf Beetle 1.9 TDI BEW start researching the cost of replacing the timing belt. It's best to purchase a car that comes with service history records from the previous owner. Owners who value their car and took care of it will have a record of all service history, an indication of the vehicle's overall shape and reliability. The importance of service records is indisputable. A seller without any service records, is looking to take advantage of the "inexperienced" buyer, making more money at their expense.

Inspecting a timing belt that "seems fine" isn't enough. You'll also want to confirm when the last timing belt service was performed with the appropriate documentation. Don't just take the word of a seller saying "Oh, I think I changed it around 30,000 miles ago." Assumptions and no documents mean RISK. Calculate the cost of timing belt replacement into your purchase price if they don't have the records.

Seller: "Oh, I just did it. I think it was about 30,000 miles ago."

Buyer: "Do you have the paperwork?"

Seller: "No, I don't."

Buyer: "Well with no documentation, I'll have to get it replaced to establish a guarantee baseline. That will cost me around $700 - $1,900. Are you willing to take $700 - $1,900 off the purchase price?"

What to Replace While Changing the VW Timing Belt on the 1.9 TDI BEW Engine

Apart from the timing belt the 1.9L BEW TDI engine's timing belt system consists of 3 serviceable timing belt components. One is the water pump that is driven by the timing belt. Second is one small fixed idler bearings, located on the mid to lower area of the timing belt system. Third is the timing belt tensioner which is centrally located on the timing belt system and provides variable spring loaded tension to the timing belt.

Before going through the significant work of taking your car apart for timing belt replacement, please consider the following:

Looking To Save Money... "Can I Just Replace the Timing Belt?" Simply changing the BEW Jetta, Golf, or Beetle TDI timing belt isn't enough. Why? Around the timing belt service interval (80,000 miles), due to age the integrity of the tensioner(s), water pump, and other seals and o-rings are at the end or very near the end of their service life. Some individuals make the mistake of only replacing the timing belt. Then, 10,000-20,000 miles later, their new timing belt fails due to tensioner, idler bearing, or water pump failure.

Tensioner

Why replace your VW Jetta, Golf, or Beetle TDI timing belt tensioner during timing belt service? Just as the timing belt has a designated service life and subsequent change interval, so do the tensioners and idler bearings. It's true that timing belts can get old, begin to crack, and eventually fail. However, it is just as common for the timing belt tensioners and/or idler bearings to fail, thus causing timing belt failure.

How can the tensioners cause a timing belt to fail? Most tensioner bearings contain a set amount of grease behind the seal. This grease provides ample lubrication and ensures tensioner reliability for the designated life span (80,000 miles). During engine operation, constant thermal temperature fluctuations eventually cause the bearing's grease to breakdown and loose it's lubricating properties. Over time, this results in unwanted bearing play and eventual seizure. If a timing belt tensioner has too much play or seizes, the timing belt can become misaligned, or begin to 'burn up' and shred, causing engine failure. Thermal temperatures also affect the timing belt causing the material composition of the belt to change and accelerates it's life span, often resulting in premature failure.

Water Pump

Why replace your VW TDI water pump during timing belt service? It makes sense from a labor standpoint since timing belt dis-assembly is required for water pump replacement. The water pump is driven by the timing belt and contains an internal sealed bearing that has a life span similar to the timing belt, tensioner, and idler bearings. The internal bearing and seals of an VW water pump can weaken and is the primary reason why a water pump eventually fails.

Thermostat

Why replace your VW TDI thermostat during timing belt service? The engine temperature is controlled by the thermostat. Near the end of it's designated service life the thermostat spring temper changes. This causes the thermostat to open too much allowing the engine to run cooler, resulting in poor fuel optimization, decreased fuel economy, and less horsepower.

Special Tools for VW Timing Belt Replacement on 1.9 TDI BEW Models

Please Note: Our timing belt tool rental kits are no longer available for rental. All tool rental kits are available for sale in good used condition in our online catalog.

Do I need special tools? Can I do it without the tools?

On older single-cam VW engines it is possible to achieve general timing without the special tools. However, on the BEW TDI engine, special tools were designed for a reason. Slight variations in timing or orientation can result in a very poor performing TDI or catastrophic engine damage (e.g. bent valves).

This isn't the area of vehicle maintenance to cut corners or try to save time. On these VW models, in order to achieve 100% proper cam to crankshaft, and injector pump timing, special tools are absolutely necessary. 1.9 TDI BEW VW Jetta, Golf, or Beetle Timing Belt ToolsWhen the timing is off several degrees the check engine light could appear and a lack of performance is noticed (i.e. poor fuel economy, excessive black smoke and soot, hard starting). Remember, you're performing a crucial maintenance repair. If done incorrectly, catastrophic engine damage will result.
