I think this is the way to go, Quattro AWD and a TDi. I was dreaming of a '99 model year A4 with diesel power and started wondering. I can only assume that vehicle in Europe got a diesel engine option? If a VW 1.8T gasser can be found in a A4, why not a TDi?

What does the Club think about bolting the TDi to the Quattro transmission? Can anyone provide any useful links? I thought I'd post here in case there was already a collective of knowledge on this particular swap, thanks!

None now. Former: 2011 335d, 2010 Jetta TDI, 2003 Jetta TDI Wagon. 99.5 Jetta TDI, 98 NB TDI, 3 different black 96 Passat TDI wagons.
Yes, in Europe they exist. One forum member in MD got very close, having an Avant with motor removed and a spare euro PD130 ready to drop in.

I'm actually thinking about doing this myself on a 99 1.8Tq avant...

Ahh fantastic Danix, any idea what member this was? How would the early A4 Audi's interface with the Immobilizer setup on the newer TDis? Would it be a better idea to find an A3 spec engine and go from there? Lastly, I assume I'd need a diesel spec quattro transmission, what with gear ratios and all? Thoughts?

Under ideas for a TDI in this section of the forum I gave some thoughts of my desire to do this.

But the most practical method, it seems to me, is to import a donor car from Germany.

Example on eBay Deutschland

A4 Sedan
110 PS 1.9 TDi
67,000 km
Built 04/99
Dealer Selling price: 5,100 Euros (about $6,600 USD @ 1.3 dollars to the euro.)

A 136 PS / 310 Nm conversion kit from M-T-M [Motoren-Technik-Mayer] is only 849.00 EURO.

I estimate $2,000USD to ship the car to Northern California for example.

Then all you have to decide is which car is easier to convert to a US-spec. A4 1.9tdi quattro.

I really question how much import tax would be, all the bonds needed for shipping and the other misc. fees and payments just to physically get the car here. Nevermind the headache of EPA, DOT and other acceptance. I volunteer you to go first, I'll lead by example.

I currently lack the budget and would actually have my car shipped to Europe to have it converted in the UK or Germany if I did, as I have family in France, and the pool of expertise is greater there I believe. Doing it myself would take too long etc.

I recommended buying a German spec. Model, as a parts car for a conversion, because the only things needed for Federal DOT Safety Standards are the lights, windshield, the bumper reinforcements and side doors for the impact beams and maybe the Speedometer and possibly the Airbags. Everything else can remain. Plus it acts as a blueprint. Using your car to Federalize it is a practical option to.

Someone on the East Coast recently took their US-spec RS6 sedan and made it into a “fresh from the Factory” RS6 Avant in terms of “fit and finish”, so anything is possible with the right people and budget when desiring any European-spec Audi.

Please keep in mind, that any engine conversion, on any car, must meet all applicable Federal and State EPA Emission Standards for the year and state for which it was built – Period.

So if you take a gasoline powered 1999 VW /Audi and convert it legally into a TDi it has to meet all emission and emission equipment standards for Diesels sold in the 49 States and / or California for years 1999 or newer. Federal and California EPA regulations allow updating, but not backdating, when switching power plants.

A 1999 Audi A4 is currently, as I recall, on the EPA/ DOT list of legally importable cars along with a list of what is actually required to make them legal in the US.

Britain’s Volkswagen Driver Magazine recently featured a pre face-lifted B5 Passat 1.9TDi converted to an Audi 2.7T V6, with upgrades, that still met all British MOT requirements, which frankly, at the workmanship / compliance level, are much tougher requirements than our own DOT.
