Hi. I have a 2014 Vauxhall Insignia 2.0cdti. About 2 months ago my car went into limp mode if accelerated hard. Following this a week or 2 later I got a message '' dpf regen do not switch off engine'' message. After I did a forced regen with my diagnostic machine the car drove perfect with all power resumed, however after 2 or 3 days it went back into limp mode. It has been going into limp mode since then anytime it is accelerated hard so I drive very gently atm. Yesterday I got a engine overheated turn off engine message, then a bad misfire when restarted. AA says exhaust temp sensor at fault , sensor 2 but my diagnostic says sensor 1 and 2 both high temp so I don't know which one it is. He says the car did not overheat; it was because of the bad sensor. He followed me to garage but they said they cant work on it for a week or so as busy all week, I took car home as I need it for work doing deliveries at resaurant. THe exhaust temp sensor code has not returned but the car still goes into limp mode as it has been doing for about 8 weeks when accelerated hard. Is the car still ok ot use if I don't get the sensor changed tomorrow, could driving with a bad exhaust temp sensor wreak the engine ? also whjich one is exhaust sensor 2 please ? thanks

Hi all. I have a facelift Insignia 2014 + 2.0 cdti eco flex and a few weeks ago I had the garage replace the timing belt on it, right after I thought the car was feeling a bit slower than usual, particularly when driving up hill. this gradually seems to have got worse and a few days ago when accelerating the car suddenly lost power as though the speed limiter was on, once turn engine back off and on its ok again but not until I accelerate, and then it does it again. it seems to be gettting worse and happens now hen i'm not accelerating as hard. I took it back to garage who did timing belt, no codes for cambelt issues but he said there was one for a boost leak. I remembered afterwards that the big intercooler pipe had a split in it a few months earlier and I replaced that, so I am not sure if the boost leak code was from that time or if it is relevant now. does anyone have any ideas what the issue could be, or what other common pipes or whatever jmight be causing this \? thanks
