For a long time the VW 1.9TD “AAZ” has been a popular engine upgrade to the T3 however they are getting harder and harder to find at sensible money and so are the injector pipes.
As time has gone on, other more readily available engines have taken over in popularity to retro fit into a T3 but there are still a lot of T3 out there with the venerable AAZ sat in the engine bay doing their thing.
The supply of new AAZ injector lines dried up years ago leaving customer scrabbling around hoovering up what they could from forums and eBay to keep their AAZ ticking along nicely.
After the sad demise of the AAZ in Simon’s own T3 Westy and over 15 years of stirling service pushing the camper up hill and down dale it was replaced with a TDI. This left us with a set of injector pipes that we could have replicated and which we’ve duly done.
This then opened the can of worms of which set of AAZ lines we actually had, you see as time went on the injector lines were updated as were the injection pumps.
The differences
There appears to be 4 distinct injection pump types for the AAZ and 3 different sets of injector line sets. As usual from VW, trying to work with the parts catalogue and work out when and why they changed is a living nightmare with some injector pipes changing on a VIN number and some on an engine number. When you add in the multitude of vehicles that the AAZ is fitted to, well we gave up!
Here’s the different AAZ injector line sets, to the best of our knowledge.

Some engines had an immobiliser over the ELAB (Elektrisches Abstellventil / electrical shut off device), some had KSB (Kaltstartbeschleuniger / Cold Start Device) later pumps had electronically adjustable commencement of injection and some injection pumps had an LDA (Ladedruckabhängiger Anschlag, / Manifold Pressure Compensator) whilst others did not. There are quite a few variables at work here.
Usually the changes to the injector lines are slight, a bend in a slightly different place to give clearance to that new “thing” that they introduced. Our problem is, we have some samples but we are not sure of which age range they are from.
The sample set came from an engine fitted with the nicest injection pump, the easiest one to work with and devoid of all the whistles and bells so our educated guess is that they are from an “Early” set or a “Mid” set, that’s not to say they don’t fit the “Late” engines, truth is we just don’t know!
What we do know that we have a set that works together on a AAZ engine.
A few years ago when these started becoming a problem we started offering a machined stainless steel bolt as a solution to worn/broken pins.
Times have moved on with the T3 now, and people are demanding parts that not only do the same job as the original, but look original too.
So, we’re now happy to offer these original style UJ pins for the T3 gear linkage from 1983 on.
They’re very close to the original style, and supplied in Yellow Zinc Plate just like the original.
We’ve been making up the HT lead sets for the early Waterboxer engines in house for some time, mainly because the available kits aren’t correct for the earlier engines. Either the wrong ends, or the wrong lengths, or the wrong resistance.
We’ve had to up our game a little though as keeping up with them has become a problem as we’ve got busier and busier over the years.
It also makes sense to have the later kits made too as the prices keep rising. Every little helps!
So, we are now having our own leads manufactured to our spec and with our own branding.
Same original spec. Same quality components. Just made in larger batches to save us time and save you money!
A short write up and some photos of our trip to Viborg back in February.
Winter had been a little mild this year in the UK. We had a sprinkling of snow but nothing to write home about. So what were a couple of cold loving Northerners to do?
Hop on a plane to Denmark for a few days, that’s what!
We were invited to JP Group last year to have a look around the factory, warehouse and showrooms, but we were just too busy.
We made time earlier this year in our “quiet” month and booked some flights to Copenhagen.
Copenhagen was our first port of call as thats where the plane landed, we stayed overnight in a hotel and had a brief look around the city the next day. It’s a great place and well worth a visit for a taster of Denmark. We’d recommend it if you fancy a weekend away or a base for more exploring in Denmark and Sweden.
We weren’t here to sightsee though, so we picked up a hire car and drove the 320km to Viborg.
Viborg is a city in the centre of Jutland and the place where King Canute set off from to give the English a kicking back when we were much less sophisticated.
Thankfully things have changed and the Danish are much friendlier. In fact its one of the friendliest places we’ve been!
Hotel rooms with saunas, bars where the patrons insist you drink their rum, and give you free t-shirts, and some amazing restaurants. We like Viborg.
Right, thats the Brickwerks Rough Guide out of the way.
Go to Denmark. You’ll love it!
Friday morning 10 am, we rocked up to JP Groups headquarters and factory location a few miles North of the city centre. We were met by Martin and given what we assume is the standard factory tour. Questions were answered like “Why do the boxes smell of Tobacco” – because JP, like us re-use a lot of packaging and some comes from a tobacco company. A good thing in our eyes.
If you’ve bought from Brickwerks you have very likely bought something from JP Group, they supply a lot of parts so they have this massive warehouse, with lots of parts… lots and lots of parts. Its a big place.
So, to help the staff get around when they’re picking our stuff they have these bad boys:
A scooter that’s also a picking trolley! Sadly we cant buy one, and it wouldn’t fit down the aisles at Brickwerks anyway… but we’d find somewhere to play on it if we could!
We could show you pictures of shelves and boxes, but you can see that at Tesco, one cool bit though is the automated picking bays. Basically large moving shelves and a large robot that goes and fetches the complete shelves from high above your head so you can pick the order. It’s a clever system. It’s fast and something we can relate to at the moment… saves space.
We quite fancy one of these too!
Next to the large warehouse is the Quality Assurance dept. This is where new products are checked and any issues that are reported are investigated.
Now we don’t get many returns if we’re honest, but if there is a problem with a JP product that they need to look at, it goes here. The racks are full of test rigs and jigs and the benches are full of test equipment.
Many people have a cynical view of returns and think that when a part is returned to a supplier they’ll just deny there is an issue and look for an excuse to blame anything but the part.
We’re sure that does happen… Not here though!
One of the refreshing things about JP is that, like us, they’re concerned with any quality issues and will look at complaints. If there is a problem, it’s picked up and dealt with. It’s in their interests because if there is a problem with a part people will buy elsewhere.
The people we met there also seem to know the vehicles they’re dealing with and even Simon couldn’t catch them out! Something else that’s refreshing.
Other stuff goes on in other areas. A company with the contract to refurbish Danish train seats operates from one of the buildings. An impressive thing in the days of “chuck it away and buy new ones”.
There is even a display cabinet for items found down the seats… if you’ve ever lost a toy car on a Danish train there is a good chance its in this cabinet.
If you’ve lost a dildo, its kept somewhere else away from prying eyes, apparently.
You can probably have it back if you ask…
JP source parts from all over world, they also make a lot of parts on site. They have a large manufacturing unit where Exhausts and body panels are made, among other things.
We spotted T3 Petrol and Diesel exhaust being made, front to rear coolant pipes, Front panels. All stuff we see every day but so much more interesting when you’re seeing how its made.
And forget what you may have heard about the way this stuff is made. Theres is a lot of laser this, CNC that, and robotic others. There are also a lot of skilled workers there welding and fabricating. Some of the new lines of Porsche exhausts are beautiful!
From the manufacturing area, we moved onto the showroom.
This is the area where some of the JP Private Car collection is displayed, as well as samples of a lot of the parts they supply. We think there were maybe a few more of Stuttgarts finest crammed here than is usual, due to building work and the current expansion going on in other areas.
Obviously, we’re Transporter guys, but that doesn’t mean we can’t ogle at some sleek curvy models from time to time!
Not just Porsche either. There is a Trekker, a few Beetles, a couple of Golfs including a Mk2 Cutaway that a VW dealer didn’t have space for, a few Mercedes and and even the only existing prototype of the Logicar. Details of that HERE if you’re into quirky cars. Its in German but Google will help you translate if you’re not fluent. There is also some info on JP Groups facebook page HERE.
After we’d had our fill of exotica it was off to the Workshop.
This is an area where JP Group work on their own vehicles. As soon as we saw the 2 T3’s parked outside we knew we were amongst friends here.
Inside on the ramp was a perfect Brown and Cream T3 undergoing assembly.
Again, seeing a T3 in pieces on a ramp is something we’re not new to, but when you see it at the company who are supplying your parts it kind of makes you realise that this isn’t just a company shifting boxes around, they have a definite interest in the stuff we drive, and also in keeping them on the road.
They’re doing what many claim to do but few actually do… fitting the parts they sell themselves. We can relate to that.
After a mooch around the workshop, it was off to lunch and then the “work” bit of our trip… spreadsheets, powerpoint, pie charts and graphs. We won’t bore you with the details of that bit.
Lastly an evening meal in a steakhouse in Viborg followed by an early night and a drive back to Copenhagen via Dollerup to check out some scenery before we hopped back on a plane.
All in all, a very interesting and rewarding few days.

We know photos of boxes are pretty dull and if we posted a photo of every delivery we recieved you’d soon get tired of seeing them… but this one is a special.
First delivery of the Eibach 23mm ARB’s ready for kitting up and on the webshop as soon as we wade through the rest of todays orders and deliveries!
We’ve not done this for a couple of years but we’ve decided to tidy up and open the workshop doors on a weekend again and let you all have a nosey about to see what we’re up to.
Same format as previous years, we’ll be there about 9am and stick the kettle on, you bring a mug and we’ll fill it with tea or coffee.
Over the next few days we’ll sort a discount code so you can pre-order some quality stock so there’s no disappointments on the day and we’re not running around like idiots wasting time making invoices out!
We’ll sort some food out of some sort or other too.
We usually wind up around lunch time and the syncro fraternity meander their way up the valley to make a day of it and do some of the local green lanes.
For the 2WD crowd we could always cruise up the valley in a different direction to the Oil Can Cafe and check out some classic cars.
there have been some changes down at Bridge Works and we now have a lot more room in the car park so there should be plenty of space.
See you there!
Simple job, import van, just come in from Lapland.
We’re just going through it undoing the “modifications” (in the loosest sense) and generally getting it ready for UK use.
One of the problems is quite simple, the front side lights don’t work.
Anyone spot the problem yet?
Yes, we can’t get the grille off, so we can’t take the head lights out so we can’t change the bulbs without unbolting the clothes horse off the front.
Deep joy. Simple job we don’t normally charge for turns into an hours labour!
Well, not really but don’t you just hate it when you start a quick simple job and it turns into a scotchlok infested can of worms.
Job started as just making the fog lamp work on the right of the van (import) now it’s turned into a rats nest detangle reterminate-athon!
The joys of working on old vans!
And this is many peoples only Annual inspection and some vehicles aren’t even required to have it!
*sigh
Irritating cookie pop up.
Yeah, cookies, we have to have this stupid, annoying message here, we know you don't care and frankly neither do we.
