I think that makes perfect  sense as radiator fan is also not working

 

As I said before the CTS has no control over the radiator fans, they are controlled by a thermal switch on the radiator, you can easily test the system by shorting the pins on the thermal switch together, if that proves the fan/s are OK then either the thermal switch is goosed or the water passing the switch isn't getting hot enough and that could be a stuck thermostat, or the waterpump isn't circulating the water  but I seem to recall you saying the gauge did read 90c ?

Thanks @nige8021, I am afraid  Radiator switches in inaccessible as they are awaked location possibly need to open some pipes to reach them so gave up, But at least I learned lot about cars from you all experts Thanks you so much fo sharing knowledge.

Yes After 1 mile driving temp is going 90 degree as it was happening in past no change in behaviour observed except fan is not starting and lately noticed that coolant level is going up in coolant box but opened its lid and  felt heat inside as well ( when car was off).

Well it's up to you. If it was me I'd buy the ebay one. I wouldn't want a non-genuine brand

Today I have used different scanner app/version and found some more info which are different from last time

The quality of scan tool programming can be variable and if it is not able to be updated may continue to contain who knows what,  errors, glitches, misinformation, missprograming, etc., which low level tool and program can you trust more than the other, I have no idea.

I have checked original sensor from skoda and it is £103, worst case scenario I shall replace again with new one or even try cleaning the old one and fit it & see. wht happens.

Checking the wiring and if required cleaning the connectors is worth a look but not taking the sensor out to clean it.  You could yes it with a meter to check it is working but that will not tell you if it is working correcting in real world use.  Live data on a proper scan tool might help.

option to use 1 expert who charges huge but expert in this field got reference from few garages

Given you will be making a fifth garage visit it would probably be a lot less expensive to go to an expert and get it sorted in perhaps one visit.  I have no idea about the people who have already seen your car so can not comment on them but the expert might be so because he things about the problem and does the relevant tests with the relevant equipment, and charges more perhour but takes less hours and visits to sort the problems. 

 

It is not normally a good idea just to fit new parts without full diagnosis but if the previous part you fitted 5 years ago was not a genuine part then for £19 to fit a new genuine part might be a very good and low cost investment.  Same for lambda sensor a genuine original part would probably be better, that does not always mean that it has to have VW/VAG/Skoda stamped or a Bosch or other label on it but the actual part manufacturer used and bought in by Skoda at the car being manufactured.  Going cheap with parts and labour can often work out expensive or very expensive in the short, medium or long-term.

 

Hi Experts ,

My humble mechanic in garage had changed my fuel filter  which was quit messy as fuel filter was never changed from last 20-25k miles , it was messy may  be  effect of fuel cleaner additives  as it  may have dissolved some impurities in fuel tank which were blocked by fuel filter , Mechanic had also  change engine oil (  I suspected some petrol smell in oil which was false alarm so changed oil today since diagnostic expert will  rev the engine for testing ,  I was  concerened that it may spoil engine) Planning to change engine oil again with new  oil filter once  all issue of  running rich is  solved)  I  can drive car with cold engine  for few miles ( of course with rich exhaust- after disconnecting battery to reset the engine light) engine light comes up just after 1 mile once temp reaches 90 degree car starts switching off and losing power but with high gas it runs fine.

 

Today More problem added in my list - mechanic told me while remove fuel filter it seems he had broken the plastic housing  which seems was fragile , it seems to put new plastic housing we need to remove tank, this mechanic was always very nice & very experienced as I had taken his service for many years and never had issue with him , it is my  bad luck.  

 

Not user if any  fix can be  done with extra metal sheet to stitch on both sides for firmness . At the moment he had few plastic cable locks which were quite firm but it may not be permanent solution.   Any idea please how  shall I  go  about it to sort out permanently, probably  will visit body works and see if they can do anything for it.  I think  housing looks like as attached in image . 

 

Mechanic had feeling that fuels pipes locks were jammed on fuel filter, he has lot of struggle to unlock them. 

 

I have booked diagnostics expert to investigate P0171 issue ( though code means  car running lean  but actually car is running very very rich he saw as short term /long term fuel trims are very negative. ( -100 SHTFT & 0 to -60(LGTFT )   .  I am not driving car as don't want to pollute the environment and harm the engine.

 

Mechanic showed me by there is very small leak on end of exhaust pipe which was not root cause of P0171 , so I may have change Cat converter as well, call Skoda today abt Cat prices and they said they have stopped manufacturing these Cat converters , so possibly buying from AnroldclerkGargge worth 90 GBP . 

 

I don't why I am confident that   engine is healthy and there is no major issue on piston/rings/cylinder, let see what diagnostic guy reports back.

 

 

Keep u posted , thanks for reading very long message. 

 

Kind Regards 

raky

 

 

Don't feel like junking car for silly things.

raky, wait for the diagnostic expert's scan tool, knowledge and experience, as you have found just going off one generic code doesn't tell you a lot and just looking around isn't conclusive.

 

You have used a sensitive tool, your nose, to tell your brain that you the car is running rich (at sometimes at least unless you have a petrol leak) the car's brain can generally report it's running lean and then perhaps compensate for this by running rich. Personally I wouldn't trust any your scan tools figures that you have shown on here and the diagnostics expert will go by the figures from his higher level scan tool.  If he's any good I'm sure you'll wish you had gone to him sooner.

 

Good luck.

Thought to update you all , Car is not fully up , some issues are still in progress, my understanding is below listed  which 5 mechanic could not help , I had to dig in after reading from this website and identified possibly root cause  ( 2 mechanic were confident there is no issue  but did not have answer, wanted to open up fuel injectors and wanted to check or run more sophisticated tests on wiring or engine componenets) 

Issues & found root cause 

1. Black smoke - ( manifold sensor I think in other cars it is MAF or MAP sensor was broken 

2. White Smoke + Wet carbon( I had added CAT cleaner with less fuel which seems were concentrated and had done its job - added more gas and driven 70mph speed all became normal)

3. Car was loosing power - Changed the Fuel filter which had very bad gunk in it again fuel cleaner may have brought some tank debris in it. Fuel filter was not changed from last many years.

4. Very negative -Short term fuel trims (-100) Broken lambda sensor , even thought it was 4 months old it was faulty replaced my old lambada broken sensor and behaviour has been changed currently car is using default fuel control values , ordered new lambada sensor hope full will change and see if the is another issue in ecu which does not like lambada sensor values  ( Lesson learnt never buy any ebay new or old lambada sensors , always buy from top quality , skoda lambada sensor ( bank1) for skoda is around £290 with 2 years warranty )

5 Fan not running - Ongoing issue @Pete_Ex-Winois Kindly trying to help  me , so far changed radiator switch on my own possibly never needed but just did it.

6 Broken AC - still not looked yet ( chnaged Coolant , engine oil , and coolant expansion tank it was leaking , mechanics were testing car possibly running ver high rev, no one noticed that fan is not running car may be over heating who knows )  

 

I am not getting confident to drive the  car yet because of no fan.

 

 

Mean time 2 issue had happened while removing fuel filter 1 mechanic accidently broken the fuel filter holder which was rubber part and fixed component of tank so non replaceable ,please be careful please opening fuel filter from old cars ,

2nd  issue other mechanic  broken fan control module connector again possible jammed , needed to spend good time to understand mechanism to get it sorted ,spoken to few local car electricians was not getting early appointment, I have to step in changed to new connector.

 

Lesson learned old cars please always keep tab on many components/sensors which have X years of life they will never run for 2-3 decades or thousands of miles they will break at some point. If u love ur car and want to run for longer please keep identifying sensors and buy only original from Skoda.

 

Happy driving.

 

Cheers 

raky
