A minor win - at least they only taped over the LED, I have seen older cars where the bulb had been smashed.
Where was it last MOT'd - they are meant to actively check for both CEL and ABS lights coming on with ignition.

Yeah it sucks. I’m based in Northern Ireland. Our MOT is different than the rest of the UK, it’s the government who MOT our cars so there’s no way it slipped through. Although I’m not 100% sure if a check engine is a failure or not? But the car was MOT’d just before I bought it.

Christ on a bike… as if they taped over the check engine light?!
How big a job is it to get the clocks out? You’ve got me worried now as I had a 1840(I think) code the other day which supposed to bring up the CEL but didn’t on mine…!

I've seen the exact same thing on a mk4 someone I knew bought from a trader.
christii:
Ok so apparently it’s definitely not a head gasket.
Mechanic isn’t 100% sure but he thinks it’s an ECU issue. Also he noticed that the car backfires loads when you rev to 3500 rpm, only at stand still, not when driving. The whole car shakes when it’s backfiring!
I phoned Autotune, they assure me it’s not the map and if it was the ECU they would of spotted it. Though I’ve gone ahead and bought another ECU to try, and it’s booked into Autotune again on Tuesday so they can have a look to see if it is the map. Though I’m pretty sure the problem was there before the map, hence the cover-up job.
Anyone any ideas?
JoshB:
Are you losing coolant? White smoke from the exhaust?
You need to try and figure out where the exhaust gasses are getting into the cooling system first.
It could be a sensor issue if the misfire counter is just rocketing up.
