UPDATE 1-Daimler says France blocking some new registrations

Fri Jul 5, 2013 12:34pm EDT

* Mercedes models ready since June 12 affected

* Daimler says has no explanation for why registration stopped

* EU source says France acted because of banned coolant

STUTTGART, July 5 (Reuters) - France has blocked the registration of some new Daimler Mercedes cars which an EU source said was because of a controversial air conditioning coolant.

French authorities have refused to register Mercedes A-Class, B-Class and SL cars assembled since June 12, even though German authorities have approved them, a Daimler spokesman said.

Usually the approval in France follows on automatically from the German approval.

"We have no explanation for why the registration in France was not yet accepted," the spokesman said.

An EU official familiar with the matter said that France had blocked the registration because the cars contained a coolant that was not permitted in the European Union.

The person added that the French transport ministry had informed the Commission about their plans this week and that the Commission would discuss the matter at their next automotive meeting in mid July.

French government officials did not immediately return calls seeking comment.

Daimler said in September that 1234yf, the only air conditioning coolant on the market that conforms to a new European Union directive on greenhouse gases, could be the primary source for a vehicle fire.

It and rival Volkswagen are both developing expensive carbon dioxide-based air conditioning systems in order to avoid what they say is a fire hazard posed by Honeywell and DuPont's new refrigerant HFO-1234yf, which emits poisonous hydrogen fluoride gas when it burns.

Daimler is violating the EU directive by continuing exclusively to use the non-flammable R134a. The German authorities agreed to extend a permit already granted before to predecessor models to the new models.

General Motor's European unit Opel began installing 1234yf-based systems in its Mokka model at the start of the year.

Opel said it had found no evidence in a crash test on its new Mokka SUV that the air conditioning refrigerant could catch fire in a collision and release toxic fumes.

Nice article, very interesting. HFO-1234YF is a refrigerant, not a coolant as mentioned 4 times in the article. The second paragraph actually refers to it as being a coolant and a refrigerant in the same sentence. Sorry, I have been a mechanic for quite some time, and little technical things like this bug me, as well as most who know the difference.
