immob/possible uch fault



  leon cupra k1
Right guys, im new here so please be nice.

recently bought my self a 182 and have had a long list of problems. slowly working my way threw them, but theres on that is proving to be a bit of a sod.
intermittently the car will not start. i get the solid red immob light. this as i have researched shows that the key has been recognised but immob is active due to can bus/ communication problem.
to counter this i have completely stripped the loom from the ecu down across the box, up the wing, threw bulk head to the uch, and all seems fine.
when i do a quick can terminating resistor test across (if i remember correctly) pin 6 and 14 i get 60ohms as i should.
i have scanned the car with auto logic (dealer level) and with my snap on solus. unfortunately when i had access to auto logic it was starting fine.
i was starting to think possibly the uch is at fault.
on the way home today (after it wouldnt start for 10/15 mins) my auto wipers and auto head lights have stopped working, i noticed this as i got the warning chime when i opened the door and the lights remain on, only now working via the manual switch.
can any one add any input to this ?
im considering buying clip off of ebay. being from a vag scene i know there are some dodgey copies of vagcom on there. are the clip copies ok or knock off junk ?
cheers guys
rick
edit:thought i would add that i have removed the uch and opened it up, no visible signs of burn damage or water ingress

Im no expert on this but have seen a lot of these issues seem to be due to the earth strap on the gearbox not making proper contact. Have you tried the second key and what happens with that.

Don't have a second key but the solid red immob light shows its being detected
Which earth specifically are you on about bud

There's only two and they're both in the engine bay. It does indeed sound earth related
