Just thought I'd let you guys whats going on...
The car was brought brand new just over two years ago, and within a couple of months a just under 2k it was back at the dealership. We complained that the oil light to way tolong to extingish from cold, and that after a motorway run, when the engine dropped to tick over the oil light would breifly come on. Vauxhall changed the oil preasure sensor and told us to come back at 4,000 miles. They had overfilled the oil to stop the light coming on.
At 4k we phoned the dealership, asking to book it in again and they asked if it was any worse. We said no and they said bring it back if it gets worse, that was that.
We ourselves then changed the oil to a full synthetic 0-30w castrol edge, which helped the cold start problem but the oil light would still very ocassionaly briefly flicker when the engine was very hot off a motorway.
We lived with the problem on good faith that if anything went wrong vauxhall would fix it for us.
We have been very loyal to the vauxhall brand over the years, actually having 9 brand new vauxhalls in the last 10 years. We have five vauxhalls at the moment, two vectras on 56 and 58 plates, two corsas on 57 and 09 plates and a 53 reg frontera.
We continued to change the oil ourselves using the best oil and genuine parts believing it benifitted the engine more than vauxhalls equilvent fix of over filling the oil! It has been changed three times in 30,000miles and two years.
THe engine suddenly started to get worse very quicky, the oil light was coming on more and more, and the engine was now rattly, something it only did at start up before it now does all the time.
Now the oil light take around ten seconds to extingish from cold start, it comes on if it is left runnig on a hill and goes in and out of 'gimp' mode all the time. It is now sitting in the garage, unused becaus of the iminate failure.
Vauxhall never wanted to try and fix the engine as every dealler seemed to have little knowledge of the vvt mechanisium, insteed suggestting enigne replacement, but because we have missed one vauxhall service, they will not do it under warranty.
The top end is worn, vvt mechanisium is worn, compression is down.
We are now searching for another engine from a crashed car.
Lesson learned; car should have been rejected from new, do not rely on good faith as a loyal customer, and always let the dealership service it, even if you do so yourself afterwards.
