I'm having some trouble with my cruise control working.
I Logged block 066 in VCDS and on initial check, it appeared the brake switch/clutch switch etc were working, but I was told it was the clutch switch so I replaced it nayway,
I then noticed in block 066 that the second last digit in field 4 was 0 when it should be 1 when vagcom is switched on. I guessed the switch was faulty, replaced this, still no good.
I now know that I can check the switch outputs, so have done this and the switch performs exactly as it should, as do the brake switch and clutch switch.
in block 066, there are two speed readings. When I drive, only field 1 shows my speed. Field 3 does not.
In parking assist module, I'm also getting this code:
00625 - Vehicle Speed Signal
27-10 - Implausible Signal - Intermittent
Is it possible that this is causing my fault? And if so, where does it take this speed signal from and how do i test it?
On a slightly related note, when I try to scan module 03 - ABS & Brakes, the car beeps and flashes which I'm told is perfectly normal, but it wont access the module. Going to try a different cable, but if its not the cable, anyone got any ideas why I cant access that module?
