TCS Error won't start.

[Guckster]

Dear Forum,

 

My 2011, 2.0 Diesel, Skoda Octavia is failing to start regularly.

Engine turns over but will not "fire".

Error message displayed is "TCS Error" in the centre of the dash display.

No warning lights. One thing I must mention, and I have only noticed this, because it has failed to start so many times, is that the engine will turn over even though the clutch pedal is NOT depressed. Note: This car normally requires that the clutch pedal be depressed in order to start. Not sure if this is related to the "TCS" error, but this is what is happening. Car can go for days no problem, but sure enough the problem will return. Usually, turning off (several times), will clear the fault and the car will then start normally. Indeed, I have noticed that "if the engine does not turn over", when the cultch is out (as should be the case) then the problem is not present and once I send the clutch to the floor it will start as normal. I have ran "OBD Eleven" and cleared all faults, such as antenna short circuit, EGR Flow - P0401, wire for speed signal, ECM 01314, but I don't see anything that stands out as related to this problem. Could battery in transponder key cause this, I'll use second key for a few days and let you know if there is any improvement. Any help much appreciated and thank you.

P.S: I have noticed another previous topic almost identical to this, but it is left "open ended", without the final repair / solution posted.

Ever replaced the battery?

 

A weak battery can cause plenty of strangeness on this generation of car.

[Guckster]

Weak battery, yes will definitely consider. I'll check voltage engine off and voltage running. Its worth a try, might explain morning (non)starts, but it has happened after good (20 - 30 mile) drives also. I see if there is a date on the battery and post a reply so as help for someone in he future.

[Guckster]

Sorry, meant to say Thank you.

New battery 2 weeks ago and problem remains. Ran diagnostic.............................

That points at either ECU wiring (power, ground, CAN bus) or a faulty ECU. If the ECU can't communicate it would be getting the signal to get it to start.

 

Other than that, you also have an EGR fault code, if you had the EA189 emissions fix in the last 2 years, you might be able to get Skoda to fix the EGR for you.

Ok is ECU wiring the best case scenario and the actual ECU is the worst case scenario when it comes to costs of fixing? 

 

Also how to determine whether its the ECU wiring or the actual ECU is faulty? If it is a intermittent problem that is car sometimes drives or a permanent problem where car doesn't start at all then which one suits faulty ECU wiring and faulty ECU?

 

Last thing I want to do is spend £hundreds on a replacement ECU only to find out at the end that it was just the ECU wiring you know what I mean. I have similar problem to OP and my car is a 1.6 petrol. EGR is for diesels?

By checking the continuity of the power/ground/CAN wiring and then load testing it to rule out any high resistance faults.

 

The ECU can be sent off for testing.

Ok can these be checked simply with a multimeter or what tools/equipment is needed? What can cause high resistance faults?

 

If it the ECU wiring that is faulty then is it a easy cheap job or a complicated one where all wires from ECU to all points in the car that needs to be replaced that is metres and metres of the stuff or tracing all the wiring paths and looms and the wiring harnessing etc?

Well a multimeter will confirm continuity, a battery and a halogen lamp should be fine for load testing. High resistance can be caused by corrosion or damage to the wiring.

 

You would need to check a wiring diagram but I'd expect a twisted pair for CAN-bus and probably a couple of grounds and power wires. Those are the only wires that should need to function to communicate with the ECU.

 

Just to point out, although your symptoms might match the original posters, until you've got an autoscan which confirms there are communication errors, you're just stabbing in the dark hoping to find the problem out of shear luck. As per every other thread you've posted on, get a autoscan from VCDS or similar! It's likely to save you money on replacement parts and hours of work...

Ok so all in all about about 5 or 6 wires correct?

 

Are these wires are easy to replace just where the the actual ecu is under the windscreen wiper?

 

I believe most likely i have the same problem as the OP as his and my symptoms are similar.

[langers2k]

I would imagine so, you need to check the wiring diagram for your car to confirm exactly which wires you should start checking. As a reminder, some wires will be connecting multiple modules to make sure you disconnect everything that's likely to be attached before testing. If you don't, it's entirely possible you'll damage other modules...

It'll depend where the wire goes, again, the wiring diagram should give you some clues.

 

I believe the ECU is on the panel under the wipers and that they'll need to be removed to gain access. You should check the workshop manual to confirm. You'll probably find the ECU is attached using an 'anti-tamper' bracket and you'll need to cut the bolts off to remove it. I've no idea if it's possible to remove the ECU connector without removing the bracket.

Ok when you say disconnect do you mean the disconnect the battery 1st otherwise how do you disconnect individual modules?

 

Does anyone have the wiring diagram for 2006 Skoda Octavia 1.6 Petrol? Engine code is BLF 118029

[nige8021]

I do have access to the correct wiring diagrams, but until you get a proper readout done of the stored codes, as stated on the 5 or 6 posts you have regarding this problem, and without that info a wiring diagram is not going to be of any use to you 

[Guckster]

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.

 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......

Ok AA breakdown guy came out and found no stored codes however there's 1 problem showing on his tablet screen and that is there's a communication problem with the ECU. He checked all fuses and relays and checked visually for wiring issues for wires viewable at 1st glance in the engine bay but couldn't find any. 

 

So he said its most likely ECU needs replacing and second most likely is issue with the wiring to the ECU however he said finding a fault like a kink in wire for example in the whole wiring harness in the car will require whole engine parts stripping out to trace and investigate the paths of all these wires which sounds more complicated that just swapping out the ECU.

 

So to investigate this wiring diagram requires a whole lot of parts needed to be stripped out to fully investigate and trace path each wire which sounds like a lot of man hours that equals a lot of £££?

 

I ask because my car when it was working was worth like around a grand I say so the $64000 dollar final question is that is it worth fixing?

Sorry but the average AA man knows **ck all about a cars systems, they can change wheels and above that I wouldn't trust them.

 

In general the wiring on the engine side of VAG cars gives very little problems, (door electrics are another thing!) so it is very unlikely that you have a wiring problem, even with the "AA" mans diagnosis, I wouldn't put much money on that and would only go a full scan with VCDS, there are many other ECU's that talk to and from the engine ECU and any of them might shut down the communication system, hence why a full VCDS scan is required

I thought the car has 1 ECU. What are these other ECU's in the car you talking about?

[nige8021]

The ABS unit has an ECU, the Aircon has an ECU, the Speedo unit is an ECU, the headlight leveling has an ECU, the door locks have an ECU, the reverse parking warning has an ECU, the Radio unit is an ECU the list goes on depending on the trim level of your car, and all of these (and others) talk to the engine ECU via the CANbus network so any of them might be affecting the system and only a proper scan with VAG based equipment would show this up

Do you mean sensors? Yeah i remember seeing on his screen all showing ok including ABS is ok just communicating with the main ECU is not ok.

 

Ok lets say for argument sake that the the headlight leveling ECU is faulty, do you mean the  headlight sensor is faulty or the wiring to headlight ECU is faulty or the the actual headlight ECU is faulty? And if so if any of these are faulty then you telling me that this can cause a car not to start at all which is hard to believe?

Edited 13 May, 2019 by very452001

[nige8021]

You need to get this idea there is one magical ECU that controls everything in your car out of your head, there are multiple ECU's and they all talk to each other via the CANbus or "K"line network, so if a totally unrelated ECU in the system fails badly it can and will drag the CANbus lines down and potentially stopping everything from working (that's the bonus of modern car systems) and with a VAG based car you need to have it scanned with the correct VAG based software, the average AA man will only scan it with a generic OBD11 scanner and that will not pickup the other ECU's involved

The ABS unit has an ECU, the Aircon has an ECU, the Speedo unit is an ECU, the headlight leveling has an ECU, the door locks have an ECU, the reverse parking warning has an ECU, the Radio unit is an ECU the list goes on depending on the trim level of your car, and all of these (and others) talk to the engine ECU via the CANbus network so any of them might be affecting the system and only a proper scan with VAG based equipment would show this up

 

ECU=Engine Control Unit. There is one engine, one ECU. You are right in what you are trying to say but calling all the other modules or control units an 'ECU' could confuse people

They are all Electonic Control Units, the OP seems to be under the impression there is one "master ECU" that controls everything and as I stated a failure of one of the other units connected via the CANbus could potentially shut the whole system down
