Exhaust inspection system light on!

[Croat]

 

Manual:

 

"Exhaust inspection system.

 

If the warning light lights up, there is a fault in the exhaust inspection system. The system allows the vehicle to run in emergency mode. Seek help from a ŠKODA specialist garage."

 

Hi all 2 days ago. I was driving home from work. When suddenly engine light came on.

Turned off my radio to hear any weird sounds and pulled over on a bus stop to turn off the engine. I waited for a minute and turn it on. Light is still on. :( No strange sounds while engin is runing.

 

Went to pick up my mother from work. Was waiting for her so I turned off the engine. Hoping light will go away. Googled the light exhaust? I was confused. There was no ice on exhaust, must be inside problem. Turn it on, light is still there. I drive home. FYI from work to home I have 6 km.

 

Need to mention there's a lots of snow in Zagreb/Croatia. Yesterday it was a holiday and there was heavy snow and blizzard so the car was parked for 2 days. Today in the morning I turned only contact, light was still on. Left the car on the parking lot and went to work with my other family car.

 

Now I will google the problem. And call my mechanic. Car is out of warranty as it has 113K km so far. I am considering going to Skoda for service but first I need to hear from my personal mechanic. I did cross my mind the cold temperature might be the cause? Since it was really cold while driving form home to work and back on this temperature below zero engine didn't warm up. On my other car same light would light on on cold temperatures but it goes off after not to long. And my mechanic told me its the bad contact on circuits during low temperatures. Not sure should I drive the car until it warms up to see will the light go away? If its a real problem probably not a good idea i guess.

 

Any help is much appreciated if any on had this problem.

 

EDIT: hope it's not the DPF problem. :(

 

UPDATE: I called my mechanic. He told me since there is now weird sounds. I should drive the car until engine warms up. To see if light goes off. If it doesn't I will go to the garage to hook up the car on computer.

From the picture, this is not the exhaust inspection light it is the MIL lamp (Malfunction indicator Lamp) sometimes called the OBD lamp.

It indicates a general fault from the engine management system which also affect the emissions of the car so needs to be checked by a garage.

 

I would have expected an additional DPF light if the problem was DPF related (it looks like an exhaust can with dots Inside the can for particles).

 

 

I was going to say it is probably the boost pressure sensor (as this is a common fault on the 2L) but I see you have a 1.6.

Without an OBD fault code reader its difficult to say what the cause is because there are many problems that will illuminate this lamp.

 

Normally when this lamp is on, the engine is in limp home (limited torque).

If you hear no mechanical problems I dont see a problem with you driving the car until you can get it looked at.

 

If for example your issue is just a faultly sensor or bad contact it is likely that the ECU can "estimate" the sensor value or use a safe "substitution" value.

In this case there's no real risk to the engine & anyway the limp-home protection the engine from high RPM, boost pressure & fuel quantities anyway.

 

I'm sure there are hundreds of Octy taxis that have driven for half their life with this lamp on...

Either buy a cheap OBD2 code reader or get diagnostics done at a specialist. Post the fault codes on here or search google.

My exhaust inspection warning came on this week too along with an intermittent cruise control warning lamp also. Car is driving fine and is not in limp mode.

 

Car booked into dealers again tomorrow so hopefully I can pass on what they say could be the fault/remedy. (The car was in last week for an automatic headlight fault warning that turned out to be a windscreen sensor and replaced under warranty but would of cost £190 had it not been)

[Croat]

My car was frozen, there is lots of snow and day when light came on it was raining and rains was freezing on contact with ground. On front bumper and license plate there was few centimeters of ice build up. Hope sensor is not fault only frozen. Cuz out of warranty repair is most expensive one. :(

 

Today it is sunny and snow is rapidly melting.  :sun:

It could be a multitude of things. I had this on a Vauxhall and the garage said it was the Lambda Sensor in the manifold estimated price £400+. I took the car home and stood looking at the engine thinking well lets call the scrap man in. A rush of **** to my brain then told me to check the plugs if it were emissions....No 3 plug lead, with built in coil, fell apart when I was removing it. A £13 ebay purchase and the car was fixed.

I wouldnt bet on it beeing a frost problem.

Ive never had any of electronics (apart from central locking) go haywire because of cold weather. Had -18 today, no issues.

[Croat]

Update to situation. I booked diagnostics for tomorrow. But today temperature was in the morning +5 celsius degrees. And I noticed light is no longer on! Maybe it's really related to temperature? Will see tomorrow what will my mechanic say. Did find some on else on Croatian forum had same light on this days while on trip in Bosnia & Herzegovina. It was EGR vent related.

After talking with my mechanic. He claims faults are related to my short trips. During cold days engine doesn't warm up and logs this errors. I should definitely drive longer trips hear and there to let the engine warm up and not to have DPF problems in the future.

[Gabbo]

I expect out of those 3 fault codes only 1 will set the MIL (Check Exhaust Lamp) and that is:

P190E 00 [104] - Supply Voltage - Coolant Pump for Intercooler

 

I wouldn't expect this is related to short journey or the cold.

It sounds to me like an electric fault & as its related to the intercooler will likely give you problems when the temperature outside warms up & your engine is limited because of intercooler performance which is why you dont have any loss of power now.

 

The others for HVAC (climate control system) and Central electronic (footwell lights) have no influence on the engine or emissions.

 

 

The same Dashboard lamp will be illuminated for 90% of all of the engine failures so without the diagnostic information (which you have from VCDS) its almost impossible to guess what the cause would be.

[Croat]

Update For 7K km I have to go for DSG regular service so will check it up. My mechanic convinced me there shouldn't be any problem with pump. Temperature has risen and no problems what so ever. Driving for a month now.

 

Also few days later i forgot to mention I got low battery warning. Probably the cause for supply voltage?

Gotta love main dealers, once got told my Audi's lack of power was an internal problem with the cat, needed a new one at £400+

 

Got home, lifted the bonnet, checked the turbo and found actuator arm had come off, 2p circlip later and all was well again.

Hi guys. I have similar problem. Same car - Skoda Octavia Combi 1.6 TDI DSG (2014)

 

Went to Dolomites (cold and snow) and on my return, on the highway (motor well heated) engine started to lose power. It had power and it lost it, and so on an off. On same parts of the way I could drive only 60km/h, then it got power back. At that day, no lights went off. 

Next day, when I started my engine, yellow indicator went off. Went to tester at my mechanic - he said that intercooler coolant pump reported a failure, and it would have to be changed. I did (because I really experienced loss of power). But after a day, the light went back again. 

Back on tester - again it showed coolant pump. I am nearly 100% sure, the coolant pump is not the problem. 

I also got this code P190E - Supply Voltage. 

 

Does anybody have any suggestion how to address this? Is it the power of the main car battery? Something else?

 

The car has two identical pumps with identical part number 5G0965567 - Could it be that this fault indicates the other pump?

Thanks!

[Croat]

To add conclusion to  this thread. Problem went away by it self. In service they didn't find out any problems regarding that light. And buy the time I got to the service light eventually went off.

A quick Google search seems to sugest P190E is a problem with the voltage supplied to the intercooler pump so it seems like your garage is in the right area.

I cant answer about the number of pumps on the 1.6 engine but the problem could also be electrical/wiring related rather than a broken pump.

Hello!

I have similar problem. The same lamp appears  and the diagnostic reported the same error 18825 - Coolant Pump for Intercooler
P190E 00 [104] - Supply Voltage. I do not feel that the car lost its power. However, the lamp appears only during ignition. When I start the engine, the lamp disappear. What does it mean if the lamp is present only during ignition but not during a drive.

 

[negaultra7]

Hi can anybody tell me what error code P190D is?

Hi got this problem aswell

engine management light is on 

i went to vastech warwick vw specialist and they told me one of the coolent pump under the egr value needs to be replaced. Quoted me £443 with oarts n labour to gt fixed
