A long time ALH owner I bought my 04 with 259k miles on it.
It needed a heater core and suspension work but now at 28xxxx miles it has been dead reliable.
A little smoky on cold starts, and still with the original cam.
It still has the MK4 foibles but I am used to them.
With a VNT 17, tune and EGR delete, it is fast , fun and economical car.

If VW hadn't built the ALH the BEW would have been a great engine.

or, the ALH is a great engine because VW built the BEW

I replaced the cam on mine at a timing belt change and it cost about an extra $500-600 if I remember. It's not that bad, and you only have to do it once. I'm at 175K and it's running great. I did invest in a VNT17 and a tune when the original BW turbo took a dive, likely from a horrible experience at the dealer several years ago. The tune/turbo combo turned out so great that I went for a better clutch and SMF. That's been the most expensive adventure.

I think have worked on EVERYTHING that is a VW diesel(Except an 8.7l Skoda V-8). I have worked on engines that don't go into cars.

I can honestly say that when you have good maintenance, the right oil, and drive the car the way it is supposed to be driven, the BEW is maybe not on par with the ALH, but in some respects, it's more durable. We do not get a lot of work on the BEW. We get a TON of work on the BRM. It is not just that the BRM has 10 more horsepower, but the way the cam was overloaded.

Probably the one way that the BEW is better than the ALH is that the injectors are very durable. But to upset the WVO crowd, susceptible to failure if using biodiesel. We strongly discourage of any excessive amount of biodiesel n the PD motors.

One of the best vehicle setups is the 2005-6 Jetta Wagon or Golf. They often come with the DSG and that combination is really quite sweet or a 5-speed manual. It's not a barn-burner, but it will work very well for a long time.

If there is any one thing I don't like about the BEW is the split intake port and the 'Sardine Can' EGR cooler. Most of the time, it's a non-issue.

I thought the DSG, BEW combo only came in the beetles....or am I mistaken?

Mine has the Jatco 09A transmission which has proved to be very reliable and spontaneous. No major problems with the BEW, but I only have 152K miles; bought new in '04.
I do have a Malone stage 1.5 tune with Dynamic EGR and a VNT delete.

I have so many mods over the years I have forgotten some. I bought my car with 74K miles on it, always used "diesel" 5w-40 oil and my stock cam was totally shot by 160k miles. Replaced it with the Colt 2. Still looks like new at 363k miles now.
I used to run a high concentration of Bio-Diesel (50%) in the car but the injectors do not like it. Had to stop running it.

within the world of these engines, AHU is the best long lasting, ALH is better but more complicated to work on for simple stuff but its nearly bullet proof, BEW is would be a solid gold engine if it was not for cam issues.

So you will run into cam issues with either engine, but if the car had correct oil it's whole life, it will take hundreds of thousands of miles to wear out, but most don't use VW spec oil, so it accelerates wear.
ALH is a clear winner in terms of fuel economy, mod-ability, reliability, and longevity. For power, the ALH was rated for 90hp/155 ft/lbs of torque. BEW at 100hp/177ft/lbs of torque. It's not a huge difference, albeit, slightly noticeable. Another thing to consider, is that the BEW can have injector problems. VW quoted my neighbour $1,000 CAD per injector for his BEW! He found a junker TDI and replaced all 4 for $200. They only had 80k miles on them and 30k down the road with these "new" injectors, they've gone bad again. I've heard similar stories.
To say the ALH is bulletproof, is an understatement. If you know diesel trucks, it's like the 7.3 of powerstrokes. Undoubtedly the most popular and the best diesel put into their cars. The ones that followed certainly declined in reliability and economy.
I'd say, find an ALH and mod it. They are an amazing engine, and they are generally known as the diesel engine that made diesels attractive again in passenger cars.
Great post. Enjoyed reading it.
And I think you're correct, even though it's a large statement, with "[ALH is] the diesel engine that made diesels attractive again in passenger cars." Quite a good point, and I think it's accurate. It certainly wasn't anyone American, Japanese, BMW or even Mercedes.

I think there is a love for the ALH as being the best of the best - it's a great engine, but I think the BEW loses a few people because it's a bit different.
I think the "bit different" part is valid.

Good thing the cam issues are somewhat easily fixed, no?

I'm happy to find this thread as I have recently found myself discarding MKVs when window shopping on CL. I previously thought the post ~2003 diesel motors from VW had missed the mark, as most diesel engines did when they had to give up mechanical rotary fuel pumps and turn to computerization. Although my education is limited with diesels, I observed the same thing happen with the Cummins i6 motors. The 12valve guys hail it as the best thing to ever grace the earth. The 24v motors added valves (obviously lol) and electronics to comply with emissions, and was still a pretty good motor. The next Cummins iteration (2003- ~2009) fell short and ran into issues previously unthinkable from what I read. Same with Ford. The legendary 7.3 got replaced with a craptastic 6.0. Trucks with them motors can't hardly be given away on CL.

Not sure anyone ever wins in these discussions, but I did want to point out to 2000alhVW that all TDIs are electronically controlled. If I'm not mistaken the '96 Passat TDI was the first drive-by-wire VW sold in North America. The electronic controls are a big part of why the rotary pump TDIs run so well and deliver such excellent fuel economy. They were a huge step forward in all ways from the AAZ engine that preceded them. Truly a breakthrough.

I like PDs, and I would venture the BEW is the best of VW's PD engines. Cam wear is much less likely than on the BRM or BHW. Turbos fail earlier than on ALHs, EGR valves are problematic, the clip connectors on the intercooler piping wear out, and some BEWs don't have replaceable valve cover gaskets (and valve covers cost a lot). But overall it's a good engine. Doesn't deliver the FE that an ALH does, but it is more refined. Injectors are almost impossible to service in North America, too.

But I'd buy one under the right conditions. Probably won't however, because my ALH simply won't die. :-)

How do you tell if the seal is replaceable on the pd cover?

click on the graphic in this product and you'll see how you can determine whether or not your valve cover gasket is replaceable.
