It may not be sold in the U.S. with a diesel engine after all, but the 2017 Porsche Macan was recently ensnared in the Volkswagen diesel scandal.

Shipments of the small luxury crossover were held up at ports for weeks pending regulatory approval.

The issue prevented Porsche from shipping the vehicles to the 13 states subject to California Air Resources Board (CARB) certification.

Regulators are scrutinizing new vehicles more closely after the revelation that Volkswagen used "defeat device" software to cheat on emissions tests.

The cars were finally released Monday, reports Automotive News, to the relief of dealers eager to restock supplies of the popular Macan.

The delay affected an unspecified number of vehicles destined for the CARB states, although vehicles destined for other states were not subject to the holdup.

The Macan was Porsche's second-best selling model in the U.S. last year, after the larger Cayenne SUV.

Cayenne Diesel models built for model years 2014 through 2016 are among nearly 600,000 U.S. vehicles affected by the ongoing diesel scandal.

Along with the U.S. Environmental Protection Agency (EPA), CARB must approve any proposed fix for these vehicles.

Porsche sells diesel versions of the Macan in other markets but, while it was discussed, they have not been imported to the U.S.

For the 2017 model year, Porsche did add a 2.0-liter turbocharged 4-cylinder gasoline engine for base models, augmenting the existing 6-cylinder engines.

While new Macan models are finally heading to dealerships, the Cayenne Diesel is still among 85,000 vehicles equipped with 3.0-liter V-6 TDI engines in need of a recall.

A proposed modification plan for these Porsche, Audi, and Volkswagen models was submitted to CARB and the EPA in February, but there has been no news of it since.

The two agencies rejected a separate plan for 482,000 cars equipped with 2.0-liter 4-cylinder engines, saying it lacked detail.

Volkswagen now has until April 21 to come up with a plan that satisfies regulators.

But EPA Administrator Gina McCarthy is skeptical that VW will meet this deadline, which was set by U.S. District Court Judge Charles Breyer after the company missed a previous March 24 deadline.
