Well Ray, did you get to the bottom of this problem. Thank you.

Would anyone be able to post a picture of what the "auto" lights switch should look like. The guy I bought car from did mention he changed it for car test. I have noticed it is not original and not an auto type switch. Can anyone tell me how auto lights function when working normally. Are the fog lights day time running....is there a light sensor in my 2011 ?. Long shot but maybe just maybe this could be causing some errors also. Thank you.

Thank you. Getting EGR fixed in dealership at the moment as this has definate error. Will update and scan as soon as I'm back on the road. I will keep you posted. P.S appreciate the time you took to post.

Stevenc, another tip.....mine wouldn't start.....can't remember anyway in the last 48hrs or so. So......I thought I'd plug in my diagnostic equipment and run while traction error light was displayed. I fumbled for my phone my connector to diagnostic port etc etc basically I left it sitting there with ignition on for a couple of mins....Guess what...up popped msg to depress clutch and it started normally. OK big deal but my point is this.... bear in mind this is based only on this happening once...but if left sitting with ignition turned on, it can rectify itself although not ideal at least I'm not going to be stranded... Normally I turn off and on and off hoping each time it will work. Maybe patience is an option here. I'll update whenever won't start occurs and if leaving it sitting there "ignition on" serves as a temporary remedy. It's not something you would naturally do when in this situation, I.e. just wait for it to remedy itself. Need clarification on powersteering. Langers2k sounds good and I think your on to something, but need to be sure. Does powersteering communicate with ECU or is this communication via brake unit. Is it the brake unit that tells the powersteering how heavy or light it should be. If it's a fail safe, it's quite possible that it's instruction to active is coming from ECU because brake unit is not communicating with ECU. Anyone ....anyone...

Langers2k, noted and perhaps I'm not familiar with some details and jargon and pardon if I'm adding confusion but 2 things. 1. Powersteering should not be active when ignition on ---- when all is good. I'm after going out to car to check. If anyone wants to correct me fine, but on a 2.0 tdi 2011 that's what I have. 2. Can anyone tell me which module handles the TCS?. If this module has a fault, perhaps it is not the ECU. I would like to thank you for your comments about EA 189....you are right and I will get back to this later...next week when car goes back to Skoda!

Stevenc can you let me know model year engine etc. Just for my info please.

Yes Stevenc, and no one has commented in relation to my diagnostic report on the fact that I have no communication with brakes control unit. I bet Stevenc is likely to have communication problems there also. Can anyone comment on how this can be resolved which may in turn explain the TCS error as mentioned at the start of this post. Car back from dealership today not fixed. To bring back next week for egr repair but still no explanation on TCS not starting error. In fairness I don't think the mechanic is convinced it's ECU and is quite helpful. If I don't get replies here I'll open separate post regarding diagnostic communications or lack of it !!!!

J.R, Thank you taking the time to post. I agree wit has you that it's not the ECU. In fairness nice mechanic, met him this evening and he said he is trying to eliminate everything else first. Car now "throwing" up fault at the moment !!!This might take a while... P.S: When car is in "won't start" mode...with TCS error displayed, the power steering is also active. Its electrically pumped I guess. This should not be the case with ignition turned on. Again, I want to post all this to possibly help someone, down the road....

Update for Posterity...................... Car let me down bad last week...bad, i.e It wouldn't start for about 40 mins. It usually goes after like 5 attempts but not this time. It did eventually start, but I have lost confidence in it. It's currently parked at local Skoda dealer. They have already run diagnostic and reckon it may be ECU. They are to check relays etc today. They reckon ECU will cost approx €900.00 + labour. My heart is broke, I probably should get rid of it, but not an option at the moment, so there is your update. Diagnostic was run on OBD Eleven, which is VW based & to be honest I trust it dearly. Any advise welcome, maybe I could buy second hand ECU ?. Regards, G.

Oh, you mean at individual modules. That getting a little too technical, I see why you recommend wiring diagram. Do you mean your talking about fuel pumps, sensors on gearbox, sensors on engine, EGR, airflow sensors, ABS etc, etc......

Thank you everyone for your help. I will run diagnostic again soon and post, Why you ask ?, well car hasn't had "starting issues" since I last cleared DTC's, and I am hoping as "fresh" scan will give a truer reflection of actual faults. Again, appreciate your comments and help, also, I can check wiring at the ECU. I can check loading and continuity, but pardon my ignorance, but where do I check the "other end". Hope you know what I mean.

New battery 2 weeks now, problem remains. Just ran diagnostics and this is what I get. I'm going to post this in a new thread (if needed) and see if I can get any help. Thank you for you replies.

Well avi4tor, you a true gent for replying. I'll try a battery and let you know how it goes. It's literally just after doing it 3 times before it started. Thank you m.
