Hi guys, I've been having several problems with my Astra and was wondering if any of you would be able to shed some light on the solutions.
1) The speedo and abs are very temperamental. Sometimes they work fine, other times they wont. I often park the car for 5 mins, and they have started/stopped working again. I understand this is probably to do with the nsf abs sensor. This has been cleaned and put back in. Could it still be the sensor, or perhaps loose wiring?
2) Ok, this is why I put this in the engines section. My car idles around 750rpm. Sometimes it will cut out when I slow down and put the clutch in. I have read about this, and it seems a common fault, usually fixed by cleaning the throttle body. Well, mine wasnt very dirty at all, but I cleaned it anyway. Unfortunately, it has made no difference. Sometimes it will idle fine, other times it will drop straight to 0 revs. Could it be the EGR valve, or maybe the thermosat (see number 4)? The car works better with air conditioning on, as the revs increase.
3) After cleaning my TB, my friend dropped my bonnet from a fair height, and now it wont open again. The latch is sticking out the front of the car, and wont go forwards or backwards, and the lever inside the car and be pulled or pushed, but nothing happens. How do I fix this?
4) The temperature gauge is very weird. It seems to take ages for the car to warm up, it will then move up to about 80 degrees, and then will randomly drop to the stop again. If I'm sitting in traffic, then the temp will rise to about 90, and will sometimes stay there for a while, but after having been moving for a bit, it will drop back down to the stop. Also, sometimes after leaving the car parked for 15 mins, the temp gauge will read higher when I restart it than if Id been driving for 30 mins. Could this be an issue with the thermostat? And could this affect the idling of the engine?
Many thanks for taking the time to read this. I like the Astra, but only got it recently (none of these things showed up on the long test drive!) and still have my Corsa. I'm hoping I dont have to go back to the Corsa.
Sorry forgot to mention, car is a T reg 1.8 CDX with a x18xe1 engine.
