Unfortunately, my Vectra died a slow and protracted death last Weds in the snow.
In fairness I probably never should have left the house but....
On start up in the morning, the ABS light wouldn't go out. Car still stopped, but ABS definitely not working, as tested by me in the snow.
Then after a 1.5hr 15 miles crawl in aforementioned snow, the Car/Spanner warning light lit up and remained on, and wouldn't go out. At no point did the car appear to have a fault, so I ignored it and carried onto work.
At 5.30, I left work, ABS light still on, but no other warning lights, so I set off, got about 100yds from the works car park, before first the car/spanner, then the engine warning light came on, then it appeared to loose 2 cylinders and then go into limp mode.
I was able to stop, turn off and restart, but now even on idle it was running rough and wouldn't rev past about 3000rpm. I decided to turn around and drive back to work where it was at least warm, and the car limped along in 2nd at about 15mph and would go any harder.
RAC were called and RAC man tried a selection of cures, including blowing out the Mass air sensor, inspecting the coil pack for shorts, then getting the laptop out and progressively unplugging sensors under the bonnet.
Long and short of it is, he couldn't find any fault codes on the laptop, and the warning lights for the engine had gone out, but symptoms remain, it will idle, but if you rev it, it sounds like only 2 cylinders are firing. He deduced it was probably the manifold cat that had broken up and was now blocking half the exhaust, which seems possible imo.
Car recovered to local Vaux dealer on Thursday where it remains, with techs scratching there heads as Tech2 throws up no faults at all.
They have fixed the ABS fault - needed a new wheel hub.
They agree there is a problem with the engine, but with no codes showing, they are resorting to replacing parts to see if one of them cures the issue. So far, new coil pack and new fuel pump, still same problem.
So I thought I'd throw it open to suggestion here for any ideas. I'll update with whatever i can find out in the meantime.
Car is 57 plate, 2yrs 3mths old, 2.2 direct manual. 72000miles. This is the first fault (major or minor) its had since the power steering failed at 1 week old.
