I am also surprised at the comments. I have a 406 Executive 2.0 Automatic Saloon and it is one of the most reliable and most comfortable cars I've ever owned. It is a 1999 V-reg and had 1000 miles on it when I acquired it. It has now covered 20,000 miles and I've never had a problem with it.
Previously I had a Peugeot 405 GTX, 1995 N-reg. I sold it with 120,000 miles on it and it was still running like new.
My Peugeot 406 (1.8 liter) is on road for only 22 months.
The suspension system is excellent. Driving the car is nice and easy. However -
1. The gear does not change smoothly from 1st to 2nd. The gear seems to break down from the shock/knock.
2. When speeding up, in 2nd gear, the RPM go up, then a little bit down, and them up again.
3. Occasionally, in the middle of driving, the engine stops completely. An indication of "engine imobilizer fault" appears on the scren. The car have been to the garage for more than 10 times, but unfortunately the people there don't know how to fix the problem. They keep telling me that they've replaced every possible element in the car computer, but the problem still exist.
I found this site looking for what would be the life expectancy of the 2.1 diesel engine fitted to the 406 Estate. Mine has covered 248000 miles - never been dismantled - same clutch - 1999 vehicle. Can I expect any more?. email Richard Motorfix@yahoo.com Ps never been a taxi!
I've had mine for just over a year and am pleased with it generally, it's comfortable, economical, a motorway mile-eater. But it does have one niggling fault - about 5 minutes after starting off from cold, suddenly the engine will lose power, and the speedometer and the mileage computer will fail. This lasts for about a minute to several minutes, then the speedometer dial and the mileage computer come back on again, and there's a noticeable surge in power.
Is this connected to the turbo? Any ideas?
