A lot of them still do, I honestly don't see why there bothering with it anymore, As its just creating problems for the rest of the bus, Eventually increasing Maintenance cost's... Which add that to the abysmal amount of cost cutting in this part of the Durham County business, Would just put them in a bigger predicament there already in!

When they first introduced the Econospeed chip, It caused uproar from Driver's and unions due to its way too restrictive ( Dangerous in fact ) setup, Most divisions abandoned the idea after that.. However 2 and a half years later North East are one of I believe Two still having it, Albeit with about 3 software amendments since, Its a pointless system now, And causing more problems than others, The reason its stayed as long as it has is only because it looks good on paper from the men in suits!
A lot recently which have come under problems have it taken out without being refitted, There's a canny few of them about.

Another thing it could be that the engines ECU has placed itself into Derate ( Limp Mode ) due to running out of AdBlue or a different problem which I cant remember, Though is mostly problematic with Cummins engines,The bus gives itself a 53 hour time delay from the emission's light coming on the dashboard to placing itself in Derate, Though in a lot of cases the AdBlue is never topped up in time.
