Reopening this thread as my car is on road waiting for assistance.
after 4 years of ownership, I faced the first Diesel engine pre-glow' symbol flashing issue last month. this was in the middle of drive from Bangalore to Chennai. Since there was no power loss or lag, I drove to destination and checked with VW Mount road service center, Chennai. The issue was identified as particles in air filter interfering with Mass Air Sensor. A clean up and reset & I was good to go. I complied for the dieselgate software update. Drove home a lesser Vento that day, hoping to do a remap soon.

I had starting issues since then, couple of times in ~15 starts. With accelerator push I used to get going.

Today morning I had the similar issue and did manage to start but it was quite hard push. I guess turbo was not kicking for sometime. Got it moved from parking up the ramp about 300 meters and then stalled in the road. I noticed the following,

1. Lack of power(suspect breathing issues)
2. pre-glow MIL flashing
3. start failure (I don't think its dead battery, but gave no crank)

Yes, now I am left stranded with a start failure condition and looking for some reliable solid advise. This time I am not in haste, I can tow back to my parking. Please suggest on my next steps!

Can it be a dirty MAF sensor again as I am yet to replace the intake air filter and last service did not attend to MAF cleaning (to my eyes)? Will a DIY help as explained here - <http://www.team-bhp.com/forum/diy-do-yourself/87939-diy-cleaning-your-maf-sensor-rs-120-a-5.html>

On occasion of my cousin’s marriage, we embarked into a week-long vacation starting from 23rd Feb. till 5th of March. Instead, I'm sitting in my office and typing this.
After travelling for 93kms away from Bangalore, I've seen "Glow plug indicator" blinking on my dashboard. Pulled over to the service lane: turned-off & on after couple of mins. Voila, its gone for good. After travelling for 2-3kms, it appeared again, pulled over again, this time it is definitely going to give up on me. Spoke to my SA: he confirmed something is wrong and I affirmed myself not to take any chances with family & kids getting stranded in middle of nowhere and took a U-turn and slowly reached TIN factory. Booked OLA, sent family, children & dumped all the luggage into the cab and set-off towards Electronic city.

All the while, "Glow plug indicator" was blinking, Engine Malfunction was always LIT. Got the car onto the lift and two lads quickly started inspecting the car. Found out a leaking “Turbo Hose” to be the culprit. Spare was quickly available over the counter and fixed. To confirm other checks, VAS system was connected hit another error of EGR Sensor went kaput and it costs 50K. :Shockked: to confirm that, the following Saturday day was completely spent to affirm the same with trail & error on the VAS system. Staff iterated as a common problem once the car reaches more than 80K Kms. This situation had NEVER occurred to me so far, for many kms.

The spare is not available over the counter and order was placed. May take at least a week or two for the spare to arrive. Welcome to VW/SKODA Family.


When this incident occurred, vehicle had clocked over 124382 kms. It was timely serviced at authorized service center. I've spent close to 47K for 120K kms service which is a major service. Again, I'm footing a bill close to 60K. The tires are screaming for a change.

Now the million dollar question comes to my mind: Whether to keep the car or sell it?please:

EGR sensor costs 50K? Impossible. I think they are replacing the entire EGR system for 50K. Why don't you just get the remap done with EGR Off?

Just to update I'm still stranded, will pull car to parking tonight. towing to service center is insane as I'm 60km away & towing charges told to me by Roadside assistance(toll free) was @ Rs 4500 for 20 km.

So are you suggesting I check for bleeding hose? My battery is cold when cranking with just about 7 volts. Otherwise healthy at 12.5 amp.

A bunch of thanks to Dr.Naren & Rajiv. I vow both of you a treat for the help you guys you've done. clap:
Rajiv had disabled the EGR Solenoid & went for a test drive. Acknowledged, there was no display of "Glow plug indicator" blinking on my dashboard.:D

I'm picking up my car tomorrow. Fingers crossed. Will certainly keep the forum updated.

Haha!! I would wait for you to drive the car and confirm lol:.

Rajiv told me that he has switched off EGR system in ECU map and there was no error code. Actually it did not make any sense to spend 50K and replace full EGR system for a car out of warranty. Now your engine would be happy too with EGR off :D.

Please do. Also update if there is any difference in performance with EGR off. I believe there would be some improvement in half throttle.

I'm in the same situation today

This morning when turned the ignition key , the glow plug light started blinking and display went into SAFE mode.

Could it be the same EGR sensor issue.

I'm in total lockdown with no ASS available for another 10 days. Can someone assist me on how to shut off the EGR ? Just to let know I don't have VCDS.

Only a VCDS Scan can confirm it after getting an error code.

That will require a ECU remap which any engine tuner can do in your city.

Rather than replacing the EGR you can turn it off via ECU remap.

It was the key fob.

It got damaged by water ingress and may be that's why the immobiliser got triggered and the ignition went into safe mode.

That I think inturn did not supply enough volts enough volts to the solenoid valve making glowplug light flash.

I changed the key fob and tried turning the ignition. It worked and no more glow plug lights flashing.

But now it makes me think , the car has clocked 150,000 kms and do I need to clean the EGR system completely. Feel the car is slightly sluggish with no smoke or no drop in fuel efficiency.

If someone can help.
Yesterday , about 1 hour away from pune to Bangalore , the glow plug light started blinking and then the engine check light lit.

Drove to BU Bhandari at Wakad on slow speed with AC off. Checked on error at service centre and it was MAF. I saw the error on the screen my self . the guy removed the error and he said it was good to go until I reach Bangalore.

Now while I'm typing this , the glow plug light is blinking.

Is there anyway , I can clean the MAF now at satara or kolhapur ? I need some guidance for DIY , if anyone can assist.

Both the VW Kolhapur and Satara showrooms are on the NH4. You could drive it till there or call the RSA for assistance if you are not confident of driving the car.

Ok. I think it will drive. No loss of power or anything unusual with the car , expect the flashing light. Will reach VW Kolhapur and show the vehicle at once.
I know it is the MAF sensor.
If someone can assist me locating the MAF for cleaning.

Hi,
I own 1.6 petrol vento, I am getting EPC symbol in my vento, followed by engine shudder and very low pickup , also in each gear my vento shudders for some time and after pressing accelerator it's back to normal.

What would be the problem

Regards
Uday Desai

EPC would mean clogging of throttle system or sensors. It could be fuel pump too ? I'm not sure.

When you press the accelerator there is enough supply of fuel and hence it is normal then.
