Went back to my garage on saturday to sort the alarm issue & raise the idling issue. Turned out all it needed to reactivate was to disconnect the battery for a while then turn on again!
Anyway, took it for a long drive this weekend here, there & everywhere. Found it very smooth at "some" mph, all fine, gave it a nice shakedown. This morning, 5 minutes from parking up at work, engine warning light came on!
I really am thinking it's MAF issue or disconnected sensor somewhere. I don't feel a drop in power, idles still between 650 & 800 rpm, no misfiring, nothing out of the ordinary to report, I'm going to have a better look at lunchtime
If you suspect the maf. just disconect it and go for a little drive. Check the air line for splits. If there is no improvment I think the Lamba sensor can cause similar problems. Hopfuly a sensor exspert will be along to give you more adivce,
On mine (Sept 01) it's the dashboard cover under the steering wheel, which as I saw on saturday, also houses the fuses & alarm module (mine's a CF3 engine)
Also, just wondering, if the MAF is busted & needs replacing, can it still be driven normally? It's just for me I need it for work (Skoda went bust again) so I need to keep driving. Is it safe?
The OBD port is definitely under the cover by the fuses on the drivers side.
A laptop, Alfadiag and a suitable lead is the way to do it yourself. Shame you're not local to me - I'd use mine to read and clear your codes for nowt.
since it's a CF3 engine a relatively cheap code scanner will do the job and reset and errors....the engine warning light (yellow one) comes on with a knacked CF3 maf. Reset it and i bet it will be on after 50 miles but the codes will tell you something about O2 etc but it's the MAF
Wow, after all that took it back to garage today. Stuck diagnostics into it - was giving erratic voltage readings at O2 sensors - turns out that there is an air leak at the throttle body - the gasket has bust.
I had that - new throttle body gasket at £2.74 fixed it.
