Good evening Ladies and Gents,
Many threads on Audi A2s, hard starting/ long cranking etc but I really do need some help and wisdom on this one.
Car is a 2001 1.4 Petrol AUA, 114,000 miles and drives nicely.
The car sometimes starts perfectly, sometimes its a long crank then splutters into life but there is no real pattern to this happening. It can be cold or warm, left overnight and sometimes it just long cranks and splutters then starts or starts perfectly. If I turn the key to position 2, count a couple of seconds then start it seems to be a lot better and will always start this way.
So to cover off a few questions and things I have already done in my rather large quest to resolve this:
1) The car when started drives perfectly, without fault and MPG is good
2) There are no lights on the dash and no error codes in VAGCOM
3) According to VAGCOM everything is good and working, sensors giving good readings and measuring blocks look good
4) Earth points checked and cleaned, under the bonnet by the lights and the two A pillars
5) Car has been fully serviced including new spark plugs, oil and filter
6) New Bosch HT Leads fitted
7) New NGK Ignition Coil fitted
8) New Fuel pump fitted
9) New Fuel filter fitted
10) New coolant temp sensor fitted
11) New MAP sensor fitted
12) New camshaft position sensor fitted *updated
13) TPS checked and adapted
14) Throttle body checked, cleaned and adapted
15) New Injectors fitted
16) One way valve fitted to fuel pipe leading into the fuel rail to see if there was some form of pressure drop at the rail itself
17) No fuel leaks that I can see from the tank, pipes or engine bay
18) Fuel pipes look all good, no fuel smells, leaks or drips
19) Injector cleaner and fuel cleaner run through the system
20) New Varta Silver battery installed
21) New PCV Oil Separator fitted
22) Pipes and breathing looks good on the car, no obvious vacuum leaks
23) New Oil pressure sensor fitted
24) Spare Key tried in case this was immobiliser problems
25) New Fuel Relay (612) fitted
26) New front Lamda sensor fitted
With all of the above done, whilst making the car run even better made no difference to the starting problem.
Anything I am missing here?
Help and wisdom would be very much appreciated as I am running out of ideas.
