Jimbo's TT
Treat others as you would like to be treated.
Hi Guys, I'm hoping for a little confirmation/help/ideas/information here.
I've got a Mk2 2013 TT TDi, and my ESC warning light has come on, on the dash. There is also a written message warning to check the owners manual on the centre section of the dash in between the Rev counter and Speedo.
My mate plugged in his scanner with the intention of just clearing the light and it wouldn't clear at all, it was a case of no communication he said, it came up with this code :-
01324 -100, 01/01, CAN BUS
Control Module for All Wheel Drive (J492)
sporadic 004-No.
From my reading and research this suggests that the ECU for the Haldex system has went awol, apparently usually caused by corrosion on the main board, or an earthing fault in the loom or plug pins again caused by corrosion.
A colleague at work suggested doing the Haldex oil and filter change as a starting point and then replace as necessay, if that doesn't cure the problem.
Personally I don't think that this will do anything other than freshen up the Haldex oil, and I suspect it will still not work, I'm of a mind to replace the ECU, the Pump (which are known to self destruct around 60-80k apparently, due to lack of or, purely incorrect servicing, my car is at 72k so, you see where I'm going with that) and also renew the filter, basically covering all bases.
The only thing that isn't accounted for in all that is that, is the earthing fault which can cause the four wheel drive system to stop working too. The joys of motoring eh?
My inclination is to start with the wiring, to rule out the earth fault, then move on to the ECU, do an oil and filter change, and then change the pump for reasons previously stated, the parts alone will come in around £500 which, as I intend to keep the car for several years, doesn't seem to bad. The existing parts have all lasted almost ten years and if the new stuff lasts the same again it'll see me out, lol.
I'll need to get the garage to do the work though mainly due to the fact that when it comes to anything "leccy" I'm about as much use as a chocolate fire guard.
So, any thoughts, ideas and or suggestions of the way to go forward, or if you concur with my logic, please feel free to voice your opinion.
Thanks very much!
