[s-cars] Cutting out at speed (mike claire)

[Eric Phillips]

Mike,

My car had the exact same problem with a 1.8T harness from one
supplier, and has had no problems with a harness from a different
supplier.

With everything else being exactly the same, and having it happen
reliably (pardon the pun) when the suspect harness is put back in, but
never on the other harness or the stock bits, I don't know what other
conclusion anyone could come to.

My suggestion to everyone on the list that wants to go the 1.8T route:
 either make your own harness, or buy one from Apikol.  You can also
get one from Addict Motorsport, but they don't advertise it.  You
hafta ask.

HTH,

Eric
