Peugeot 406 HDI Loss Of Power?
Hi, I'm having a problem with my 406 HDI. Some months ago, I had an issue with the warning lights coming on and with a diagnostic wotsit I got codes 220 and 380. One is the airbag (which by wobbling a connection under the passenger seat comes and goes) and the other I thought to be the air mass flow meter. The car has been running fine until very recently. Recently, it has an appalling loss of power, the mpg is showing a significant reduction across the speed range compared to what it used to be. Upon startup it runs rough and on pulling away, it feels like it's being starved of fuel, although the mpg meter doesn't show this. It really struggles to reach 70 mph. I have replaced the mass flow meter with a brand new one from a dealer, but to no avail, the problem continues. I'm also going to replace the fuel filter, but I can't see this as being the problem if the fuel consumption is way up! Anyoone any ideas?
Thanks.
