This car does tend to these niggly little problems which can let it down. Personally I recommend, from my experience of owning this one, that you keep away from these and all 2.0 litre vauxhalls as you are guaranteed problems and an empty bank. The engines of these cars tends to breath very badly which causes them to need constant maintenance and cleaning.
A very common problem on these cars, and other 2 litres, is the idle air valve (IAV). This tends to get clogged and can cause a lot of problems with idling. This is because the engines breaths badly because of the way they were designed.
When I first bought the car I found that the battery light started to flicker if the engine was running at low speeds. Also it idled erratically, sometimes stalling. I took it to my local vauxhall garage and they told me that I need a new cam sensor, crank sensor, idle air valve and alternator. Then they quoted me 800 pound to fix this, which is very extortionate.
I took the car to another garage and I had a second hand alternator fitted for 50 pound which did the trick. I also had the Idle air valve replaced and a new cam sensor. The car drove beautifully for a few days and I thought that it was fixed, then it started cutting out again.
The car wouldn't idle. Every time I stopped at a traffic light the car would cut out which was quite embarrassing. I found that I had to rev the car to stop it from cutting out. Also when I drove it the EML light would come on in the dash and the car would 'kangaroo' a little when accelerating.
I went back to the vauxhall garage as I thought that they were the experts on astra's, and guess what! They told me I needed a new cam sensor, crank sensor and IAV. And they charged me an arm and a leg just to tell me this! This annoyed me as I just spent out on these parts. They also told me it would cost 495.00 pound.
I went to another garage again and they told me that they couldn't find absolutely anything wrong with my cam sensor and my crank sensor. They also told my that this problem is a very popular problem with this particular car, and vectras/cavaliers. Apparently all 2 litre vauxhalls all have these same problems and it is headache to solve this problem. Its just a design fault.
This is very annoying because this car can be such a lovely drive, but when the Engine management light comes on the car goes into 'limp mode'. This causes the car to use minimum power and use more petrol.
As for the IAV, this just needed a good clean. I had this cleaned, which is a very easy task that can be done yourself, and the car drove beautifully for a few days. Then guess what! The same problems all over again.
Basically if you buy one of these cars, or a 2.0 vectra, you are guaranteed these same problems sooner or later so take note. Nothing else will go wrong with the engine as it is built like a tank. Just these same three problems over again and again. I have heard so many people with these same problems.
Nothing else to say the rest of the car is solid I suppose.
