[Warning Light] New radio and warning light
#1
I'm 30, just learnt to drive, and bought a 2006 1.9D Berlingo Desire. Everything was grand, and had it in for a full MOT and checkover in my local garage (very good reputation) to be sure. It had the original CD player in when I bought it but wanted to get something for Bluetooth / mp3s so went to Halfords (I know, I know) and they put in a decent pioneer unit, plus I got a microphone for hands free and the steering wheel controls. 

The next day the unit wasn't working, and the engine management light was on constantly. I took it back to Halfords who fixed it and assured me there'd be no more problems (there were), and that the engine light had nothing to do with the radio being changed, that it was merely coincidence. I went back to the garage (admittedly it's not a Citroën one) who completed a full diagnostic and basically said "you need to find an expert electrician because there is nothing wrong with the car mechanically", which there isn't. Their temporary solution for the light was to remove the F2 fuse from under the bonnet, and this works so far. I did try putting a 15amp fuse back in the other day as the manual says (originally it had a 10 in it), but it just gave a constant warning light and told me the oil was half empty (but the dipstick shows it as full). So at the moment, no F2 fuse in the engine.

The radio worked fine for a week before it cut out. I went to another Halfords and the fella who looked at it gave all the connections a wiggle and it came back on, but he replaced the head unit as a precaution, and on my insistence. 

The unit has gone three times since then, each time I have managed to fix it myself by a combination of checking connections, fuses under the steering wheel, attempting the F2 fuse under the bonnet etc (no fuse has ever blown by the way), but I can't pin down exactly what is failing even though I have tried being systematic - checking one connection at a time whilst having ignition on/off etc. Nothing particular seems to trigger it going - once it went when I stalled, but other times I've stalled and it's grand. It's never gone off with both the unit and the engine running though.

Now it's gone and won't come back on no matter how much I tinker. Obviously I'll go to Halfords and have them replace the wires as well, but it's a long drive to the nearest one now as I've moved house. The manual does say changing the radio should only be done at a Citroën dealership, but short of more expense I want to know if there's anything I can do, like a hard reset or something, or if there's something I should be making Halfords check for/replace too? What might they have mucked something up unknowingly when they took the original unit out?

And what's with the F2 fuse under the bonnet? The car works grand without it as does all the instrument panel. And the radio has conked out both with and without the F2 fuse in!

All insights greatfully received, barring "don't go to Halfords" perhaps, as I've figured that out already ;-)

I wouldn't recommend pulling a fuse as any solution.

They always feed multiple things so whilst it seems fine, I am sure something won't be working that should.

I haven't looked what the f2 one covers but I am sure it's not just the engine light.

First off I would put that back and then see someone better than the previous garage to read the fault code because there will be a code there. Any garage who suggest taking a fuse out because they don't know what the problem is, is one to avoid.

It sounds like it's shorting out or something but I am no expert on electrical stuff. I am sure someone will be better placed to advise on that.

F2 apparently covers the fuel pump, though having run the car almost continually without it in for a month, and getting 40 miles to the gallon I still can't see a difference. I do get your point though, thanks

Also, previous to any of these problems it had a 10amp fuse where the manual says it should be a 15. Maybe that's not a big enough difference to cause a problem?

Update: F2 fuse is only of use in Hdi engines, so redundant in 1.9D engines.

Hi, your admission that the installation was not carried out at a Citroen dealer or citroen specialist is a little worrying. The fuse boxes in these cars are not merely termination of wires. They are sophisticated computers that manage how the car and accessories are operated. Not many car radio dealers are aware of this fact and would often chop wires or tap power from an incorrect source. The system would obviously pick this up as a fault and can even shut off certain functions to protect itself. I would rather drive the car without audio than face costly repairs. I'd recommend that a dealer or citroen/peugeot have a look at the installation.
