Hello All 

 

No obvious symptoms. The ECM and start-stop error came on today. After running through the culprits previously flagged by the knowledgeable forumites, without success, I put in the trusty OBDii

Reader and got the following 

 

P0111 (pending) IAT sensor 1. CKT range/performance 

 

I also have a Carista bluetooth reader and for double check got 

 

VAG code 30162 O2 sensor 1 bank 1

And a search result this might affect starting. 

 

Before I start the long drive to a dealer. Has anyone come across this before and can I do anything myself? 

 

Regards and thanks in advance 

 

 

Always worth a look at the sensor and its connection and wiring just in case it's something obvious.  Also check the engine air filter and its housing box to make sure they're not badly contaminated or full of whatever.  You don't say what year (or other details) about your car so if the air filter hasn't been changed (VWSkoda put at a silly 6 years/ 60k-miles) then a new fresh good quality filter may help and often helps the engine regardless, stops some muck getting into the engine and expensive exhaust bits.

 

Let us know how you get on.

Thank you so much. Sorry I forgot to say - 2019 TSi. Just under 30k miles. 

 

I did get all the filters, including cabin done in March with service. But no harm checking. 

 

In respect of the sensor. I could not see any wires round the air filter box. Am I looking in the right place? I imagined it was near the intake but nothing obvious there. 

 

Regards Bob

The following video seems good for giving general background info to P0111 but you could try clearing all error codes and see what returns and which might be first to return.  Different scan tools can give different readings.

ETA: Bob, I don't know 2019 cars (far, far too modern for me) do I take it that it's a 1.0 3-cylinder(estate) engine code does it for those with more knowledge.

ETA:

Bizarrely it's stopped now and gone back to normality, including start stop. Without me doing anything. I hate modern cars. In the old days a warning light coincided with engine on fire 

I'm not a fan of these over complex computer programs.

 

If the fault has gone good but I'd not rely on that.

 

My number one thing and I presumed you'd seen it is car battery too low in charge for the computer programs, that's not any signs of trouble with starting the car or lights not bright enough or even warning lights and messages.  Sometimes driving the car and/or less use of the very many electric items on a 2019 car can take the battery back over the computer satisfying threshold but much more driving or a session on a suitable battery charger is often needed to stop another reoccurrence too soon.

 

Test your battery at its terminal posts a good few hours after the engine was last run if you get less than say 12.2V or 12.3V (allowing say about 0.2V drop if the car's computers are still active whilst the car is a rest) then either a good run without using much of the electrics on the car or better still a full top up charger with an appropriate charger maintainer.

 

Other thing is that all electric connections are secure, battery post clamps and main earth connections on (also helps if they're clean too).

 

My wife's car registered misfires after I disconnected and reconnected the previous battery, never had any since.   

I also think if you have a scan tool or code reader that delete the error codes fully that can help, less for you and the car to be concerned over.

 

Let us know how you get on.

 

Sorry for the delay replying. A cold laid me up. Not a sausage has happened since and the car has behaved itself.
