As the youngest mk3 is now 10 years old these are starting to show there age. Split or gunked up breathers can make problems. this also works the other way.stalling when cold but ok when warm. When starting from warm the car behaves as it's running with the choke out, the rev's are too high and often don't want to settle below 2500rpm and this controls the fuelling and when faulty it makes the mixture richer (as the engine believes its still cold). The sensor is behind this bracket and is held in by an allen key which is likely to round.the engine mount bracket has the flippin starter motor attached The bolts go through the starter motor and into the bracket.Ħ ecu temp sensor stalling only when hot/cold one to lift the car and the other to support the engine while the bracket is out. The part # for the 'crank angle sensor' is.037 906 433 and is the same for 8 or 16v cars, You can buy non-vag, the brand is called 'FACET' (made in italy) Its the same part with the same # on the box and a bit cheaper tooįitting: you need to remove the front engine mount bracket so need at least 2 jacks. Should show on vag-com as an error but its also worth checking the wires as these get brittle and break with age!ĥ Crank angle sensor/engine speed sensor/pulse sensor Cutting out/oil light flashes The originals were made in Tunisia and are a known issue!!įixed to the side of the dizzy and also stops the engine reving over 5000rpm. Make sure you get a light grey/brown coloured one with 'made in germany' on it and it comes brand new in a vag box. so cold relays means faulty relays!ģ faulty fuel pump relay no167 rough running If it isnt 100% clean this is well worth doing and solves many idle/stalling issues.īoth the 8v and 16v have the same #30 ECU The #30 relay part # is 165 906 381Ĭheck them by feeling how hot they are after 15 minutes of driving. ![]() Hopefully this will help people locate and fix thing's when the problem's start but the common fault's seem to beġ dirty throttle body Lumpy idle/Stalling at idleīuy some carb cleaner for around a fiver. ![]() So if your car has the common engine running issues.read this thread. I have started this thread and hopefuly this will make things easier when you get the Common "Mk3 running issues!" The list is quite long and every car will behave differently and even 2 cars with similar issues will have 2 different faults! (hence why no "my car is stalling" info).
