Ok ladies and gents, My VL turbo has a really rough idle and dose not register any thing on the tacho! (e.g tach reads 0rpm but the car still runs) However once in a farking while it decides to oscillate & then run smoothly & sits on 750rpm! I have replaced leads,plugs,coil,dizzy cap,rotor button & o2 sensor & its still not happy Next step is to replace cas and then maf sensor but if any1 has some ideas as 2 whats causing this problem then i would be much obliged
P.S I have also tightened all fittings 2 the cooler and the bov has been set properly! Im also not sure how 2 run a diagnostic so if any1 can help it would be much appreciated! Finally, the car has a ticking noise that sounds like an injector but i cant seem 2 isolate which one it is even with a stethoscope! anyway any help would be great! Cheers.

Thanks 4 the link mate
Ok did the test and codes
11-cas
12-afm
13- coolant sensor
21- ignition circut (possibly showing due to turbo timer)
34-detonation sensor circut
All these codes have come up I have disconnected the battery and these codes still show? Could all these sensors really be failing? When i bought the car it was running sweet & other than a rough idle and a slight misfire it runs fine???

check your coolant temp sensor and AFM sensor and wiring plugs, boths of these will cause the car to run very rich when not working
IMO a Cas will **** it self before it logs a code, remember that vl ecus are very basic.
det sensor will only remove 5degrees in certain sections on the map if faulty or disconnected

Thanks for all that info mate I did a clean on the K&N filter the other day, it was filthy, but i haven't checked the actual condition of the afm, however i did clean all sensor terminals! Also the car has been going through a fair bit of fuel (its unregstd but even idleing in the driveway its chewing a fair bit) but the o2 sensor was dead so that obviously was not helping matters! I will look @ getting a coolant temp sensor from the wreckers and see if that helps
