I've now done about 11,000 miles in the 124, having got back from a tour of Germany, Austria, Italy and France this morning. The car has behaved brilliantly, again, this being the third continental trip we've done in it in 2.5 years. Being able to throw the hood up and down in seconds is brilliant, and even the fuel consumption's been good at around 40mpg. Only downside is boot space for my wife's packing....
However, on a long (350-mile) bit of German motorway a few days back with the hood up, I became aware of a faint transmission whine that appeared at around 72-3 mph and stayed up to around 80. As it is linked to road speed and is present with light to hard throttle pressure, but goes the instant the loud pedal is released, I'd say it was differential noise. It's a faint, fairly high-pitched whine which is (obviously) more noticeable with the hood up.
Has anyone else had this, or does anyone know of a reported issue with the LSD unit? Not sure if it's the same as the ND Mazdas or not. I need to decide whether it's normal or not (it's not very loud at all - yet) as my warranty will be up in November. I'll probably take it to the dealer next week, but I suspect they won't be able to hear it easily. Any thoughts gratefully listened to!
