Variators: Which engine

According to the Maserati technical bulletin *any* engine (4.2 or 4.7) with an engine number of <148697 is potentially susceptible to variator issues

My very experienced shop's owner tells me that the incidence of variator problems in the dry-sump engines is about 1 in 20, while the wet sump 4.7 L from 2007-2010 has about 1 in 3 needing the big fix.

Should be on the documentation of the vehicle. If not it's stamped on the block (somewhere)

Any indication of the correlating year when engines numbers above that 148697 started ? Seems like 2011 or so ?
Just curious when Maserati fixed the variator problem and if it's safe to assume that all GTs after that year ( whether it's 2011 or 2012...) are unlikely to have this issue ?

I don't think I'd risk trying to pin it to a year. There are all sorts of cases where old components have been fitted to much newer cars. For the sake of a quick check of the engine number or of documentation that it's been fixed.

It will be at the dealer next week for the 12 mos service , so I'll ask them for the engine number since they'll change the oil and various other fluids, so they'll be near where the plate or " stamp " with the number is located .

Just hoping they're a bit more experienced than the other dealer service department ( mentioned a different thread ) who never heard of a variator. Hopefully I won't have to point at the front of the car and tell them : " and this is where you'll find the engine you're going to service " :-) :-)

Unbelievable ! The dealer said they had no access to view what number is stamped on the block in the course of what they did for the 12 month service . According to them , you'd pretty much have to take the engine out of the car to see that. Also, they have no way of cross-referencing VIN with engine numbers . Disappointing ...

Unbelievable! I was the one who started the other thread you referenced. A couple of members have said they have a way to look it up, but I haven't received anything from them yet.

QP5s assembled after September 2010 had the variator upgrade at the factory. This corresponds to the engine number mentioned in earlier posts.

I don't have data for the GTs.

I called the Jacksonville dealer today to order some parts and they casually told me what my engine number was after giving them my VIN. My GTS is a 2010, and engine number was 157,404
