  1. Erratic central locks 166 TS

    Alfa 164 & 166
    Yeah, so my problem is that when in lower gears, or braking, the central locking starts to click on and off. Like an relay sound coming from the back of the car. Not sure if it actually locks the doors on and off, but it sounds like it. Also the central locking does not work when used from the...
  2. Subtly erratic revs

    Alfa 147, 156 & GT
    As per previous discussion, ive been raising the revs on the jts to about 1500 when stationary for longer periods of traffic lights just turning red etc. This is because its possible the lean burn at idle of the jts may be contributing to additional carbon build up in the inlet...
  3. Erratic Alarm

    Alfa Giulia
    Minor issue - my alarm keeps going off for no reason, it started the other week whilst we had a thunder storm - overhead clap of thunder off the alarm sounded, another storm last week and again clap of thunder off the alarm went. Saturday morning alarm went off twice - dry conditions, no thunder...
  4. Erratic coolant fan or normal on TS 2001?

    Alfa 147, 156 & GT
    My friends' 2001 1.8 TS seems to have an erratic fan? It spins briefly for short bursts before reaching 90 c and then when the engine is hot in traffic the fan does not cut-in until rather late when the engine temperature is high (around the three quarter mark) but before the last marker and...

    Alfa 147, 156 & GT
    Just wanted to share some recently acquired knowledge , after a lot of research finally found the cure to erratic reading of an oil level display (you know the one that appears briefly when you turn the key to ON ) One of my 147 JTDs was showing erratic reading, every key on it used to show a...
  6. 159 2.0 jtdm erratic idle

    Alfa 159, Brera & 946 Spider
    As title. Steady when cold and fully warm but erratic when in between. Say when it's been off for maybe a couple of hours only. It doesn't stall but drops quite low before picking back up. Then driving off all is fine. In the old days I would have been looking at idle control valve but who...

  9. Erratic rear wiper behaviour

    Alfa Giulietta
    hi guys, my rear wiper went a bit nuts this morning, i can't remember exactly what I did, but I think I had auto wipers on, dipped beams, A/C etc, i turned on the rear wiper to get rid of a bit of dew and it just kept going at full speed, not intermittent but full speed, like it does when you...

  11. GT JTD Erratic Running

    Alfa 147, 156 & GT
    Hi, I have been getting somewhat erratic running from my JTD for a while, plugging in ECUscan seemed to point to the MAF (duly replaced) but I am still getting a difference in the demanded air quantity and the actual which then suggests an air leak somewhere. (EGR blanked off with a plate with a...
  12. Erratic tickover

    Alfa GTV & 916 Spider
    V6 is ticking over at between 1200 and 1700rpm. I have replaced the throttle body and pedentiometer to cure an intermittant injector light problem. This did the trick but then the tickover was erratic, have now replaced the MAF and also the air filter for good measure. Disconnected the battery...
  13. Erratic Idle on MiTo

    South Africa
    Anyone had this issue? the car has an erratic idle,when i stop in traffic the rev bounces and then slowly drops or sometimes it wont, it hovers around 1200rpm...drops to 1000rpm back up then slowly drops. If i have the aircon on it doesn't do this.
  14. erratic aircon

    Alfa 164 & 166
    Aircon on my 166 seems a bit hit and miss in these warmer months. Sometimes it pumps out lovely cold air from the off. Sometimes it starts off by sending out warm air for a few minutes so you sweat like a polar bear in Dubai before eventually sending the cold. It helps if i turn the aircon off...
  15. 1999 Spider erratic idling

    Alfa GTV & 916 Spider
    Hi all! I have just aquired an Alfa Spider 2liter twin spark. I totally love the car, but the improper idling is driving me up the wall. The morning after I collected the car, she would not idle at all after starting (she started first time). I nursed her with the throttle and then drove her...
  16. Erratic Fog Lights 55 Plate 156 SW JTD

    Alfa 147, 156 & GT
    Hi all. Fog lights wouldn't work at all because of the volumes of Starbucks coffee poured down them over the months, due to the lack of cup holder! Replaced 3-switch pack from eBay - tested it, all working fine. Now very erratic. Neither of the fog light switches work, (the ASR is fine)...

    Hello all! Recently, (2months ago) purchased my gorgeous Alfa gtv 2.0 t-spark. Excellent condition, full service history, 75000 miles! On an s plate. She has been fine until today.

  18. Erratic idle 159 2.4 jtdm

    Alfa 159, Brera & 946 Spider
    Hi, this is my first Alfa, it's a 2007 159 2.4 jDTM. Lately, when the engine warms up, instead of idling at 750 rpm, it drops to around 500 and revs itself. It doesn't stall however. Any ideas?, I'm not a mechanic, but an experienced DIYer, so try and keep it simply - Cheers :p

    Alfa GTV & 916 Spider
    Hello and thanks in advance to anyone who takes the time to help me out. I have a 2001 alfa spider 916 2.0 t spark. I've owned in for 6 years and apart from the usual issues with it the engine has always run perfectly. As it approached 50k I treated it to a full service and MOT. When I got it...

    Alfa 147, 156 & GT
    Hi all, I own a 156 CW manufactured in 2005, with automatic climate control, which has the following behavior: at engine start-up the auto mode and AC/compressor will engage automatically without being activated by me. Each time I turn off the engine, the clima system is set on manual, not...
