Hi Have a very annoying problem in that my car (2000 1.9 PDi) for no apparent reason goes into what I assume is "limp mode" The annoying thing is it can happen after I have driven for over 300 miles non stop or sometimes when only driven about 2 miles, everything can be fine for as long as a month using the car every day and then it may happen twice in a week, if it happens after a short run just switch off & on and its fine, if it happens after a very long run it has to be switched off for about 30 mins to reset. Have had the MAF changed and in between
