When Volkswagen unveiled its new 50 state-certified Jetta 2.0L Clean Diesel TDI back in January, the company line was that the car would be available in the spring of 2008. We've been impatiently waiting because we're excited by the prospect of diesel engines penetrating the U.S. market again, and no other vehicle could do more for the cause than the relatively inexpensive Jetta TDI. Now comes word from the TDI Club forums that the diesel sedan will be further delayed until late summer 2008 because of a "technical issue that was found during the later stages of durability testing."

The news comes via an email sent by VW to its dealers, who are reportedly disappointed that they'll have to wait even longer for this highly anticipated car. Brandweek cites one dealer who claims that three out of every five calls he receives is about the Jetta TDI.

The fact is, the U.S. now has the strictest emissions standards for diesel powerplants, and if an automaker wants to sell its diesel-powered vehicle in all 50 states, it has to meet the even stricter standards set forth by the California Air Resources Board. The complexity that must be involved to achieve this feat is likely considerable, especially without the use of a urea injection system. Hopefully, it'll be worth the wait.
