U0416 Fault Code - Invalid data received - vehicle dynamics control module

Post by TomRogers »

Hi all

Recently had the engine management light appear on my dash. Scanned the codes and got U0416. This translates to Invalid data received - vehicle dynamics control module. Not sure that this description gives me much to play with in terms of fault finding.

My car is a 2015 polo, 3 cylinder 1 litre engine.

The car has no noticeable symptoms that show any issue. Performance and fuel economy appear fine. No issues in the running of the engine or any power issues.

Had the car serviced by VW and they did a minor investigation and suggested it was the fog light on the rear passenger side. Which they then said was odd because it isn’t fitted with one on that side.... Cue £150 per hour diagnosis fees.

I left the garage without a fix and I am hopeful I can find the solution online.

Things I have done:
Changed spark plugs a couple of weeks before the service/light appeared.

Changed fuel filler cap after the service due to cracked seals. Garage advised me of this.

I have cleared the error and it stayed off for a journey lasting over an hour. Then the light came on after starting the car for a second time. This has been a consistent trend that the light stays off until the car is started for a second time and warm.....

The spark plugs weren’t tightened using a torque wrench, I tightened them by hand. Could it be something as simple as that?

Any thoughts to help fault find would be appreciated.

Thanks
Tom

Just to add to the above. Seems the spark plugs were changed again during the service I mentioned, so that would in theory answer my question about the tightening of the plugs.

Thanks

If this car has the 1.0 engine, without being turbo charged, I'd not think that it has much in the way of "vehicle dynamics control module" functionality, so if I'm correct, this might just be yet another S/W issue from VW and if you were brave enough to request that your VW dealership sent out a technical issue request to VW Starship Control, they might get directed to a S/W patch that resolves that - but remember I might be quite well off in what I've suggested.

I've been there done that with an unresolved duff fault codes with my wife's previous 2002 Polo 1.4 16V where it logged engine bank 2 faults and camshaft sensor faults in winter only, that engine was a straight 4 so no bank 2 and it did not have a camshaft sensor - VW dealer knew nothing about this issue or any updates, but I was not the only person in the VW Group world with that engine to have these duff faults turning up! Also a similar issue with a late 2009 Ibiza that started discharging its battery slowly after it was about 6 years old, component replaced at great expense and no sign of BCM S/W patch availability, I paid up and continued to live with that for another 6 months then talked to another SEAT dealership and luckily they had just had that issue with a similar aged Polo they had taken in as a trade in, so after requesting help from VW and getting it, they were willing to consider that what I was suggesting was wrong with my car, and SEAT directed them to a BCM S/W patch which sorted that issue out!

Does that car have ESP, if so some thing in that system could be causing this problem, but if you have had a VW dealership scan the car for fault codes, they should have found what was causing this fault to have been logged.

Edit:- I've re-read your opening post and it was a VW dealership!

From what they discovered, it does sound a bit like a S/W or module programming error at initial build, a bit like what I had with the 2 cars I mentioned earlier.

I've searched for info online, and for that fault code there were a few hits but nothing with a conclusion!

Yeah I can’t imagine that the onboard computer is overly complex given the basic nature of the engine. The dealership initially suggested there was a software update available which would fix it but I said to them if the update was the cause for the error then it would have shown up 2 years earlier when I brought the car.... of which they then said they think it was the fog light. So I have no confidence in their ability. I have another VW garage near by who I might try. Its Disappointing that the dealership who have the right tech seem to have drawn an initial blank.... I don’t yet fancy forking out for diagnostics and then a repair it seems far to pricey. The software update along was £125.

Having cleared the error again today it was fine until restarting the car for a second time once it was warm after a 40 minute journey. I’m thinking it must be something caused when the car is up to temperature. Although quite what that could be is a mystery.

Yeah a google search doesn’t yield a lot. Other than it could be o2 sensors, maf sensor, fuel cap seal, breather pipe, spark plugs, though no websites seem to have anything more concrete.

Not able to add anything about the fault but according to Honest John there should be no charge for a software update for a car under 6 years old as it comes under a 'high cost high value item' that should last at least 6 years. Think you might have to fight it though.

That’s interesting. I had the same argument with the garage last year about a software update. This was way before and warning lights. They did offer a slight reduction but I declined out of stubbornness. The warranty and service plan with the car which are still active are really not worth anything given the caveats they throw at me.

I may try and find an Independent be specialist.

Thanks

The thing is, as far as my daughter was concerned and I was concerned, in the case of her Ibiza which seems to have escaped from the factory with an incorrectly coded BCM, the battery discharging issue did not rear its ugly head until the car was about 7.5>8.0 year old - and I found that weird, I would have expected that issue to show up from day one if that car was left unused for more than 5 days - and that was not the case, even after I replaced the battery, which was aging with a new one, it still drained its new battery.

So, if your VW main dealer has suggested that a S/W patch is available, take it, the software updates are always free when they are correcting a factory build coding error, you will probably still need to accept that you will need to pay approx. 0.5>0.75 hour tech labour to get it located and downloaded and into your car.

So as an update to this.

I have managed to get hold of a VCDS scan of the car. Output below. This has thrown up a couple of things, 1. there appears to be an ABS issue. 2. The OBS code gives some sort of emission related fault code.

The U0416 code, doesn't appear to be mentioned in any of the outputs from VCDS - Confused!!!

My latest thinking is this - The ABS error could be triggered by a fault in the system, or one of the sensors it relies upon to activate e.g. tyre pressure sensor, steering sensor etc. As the error only seems to occur on the second startup attempt after driving (it doesn't do it if started for a second time and the vehicle didn't move), I am wondering if this could be a steering sensor issue, particularly as the garage, suggested I needed my wheels tracking, during the last service.

This would explain the U0416, since this is a generic error for dynamic control system, of which I think the ABS system and steering sensor might report to.

Sounds logical, however I have no real way to test this, other than to ensure my tyres are inflated correctly and I pay for the tracking to be done. Presumably I would need to reset the steering sensor???

Any thoughts?

Thanks
Tom

Hi Don't no if you have solved problem but I have had the same fault code .after doing a lot of digging I traced it to brake boost pressure sensor .£45 of eBay easy to replace. Once fitted clear code and should be all good .polo 1.0 mpi part no (vw ag 5Q0 906 207) Hope this helps

I have just got this fault code and I change the brake boost pressure sensor on my vw polo 2015 and it put the engine management light out

Hi guys I am having the same issue. Where is this sensor located and is it plug and play or does it require any special tools

Cheers

I can also confirm that buying the Pressure Sensor Brake Booster actually cleared out the check engine light (I have had it on for a year at the least), and yes it is a plug and play part

Hi

I have just had the same issue with my 64 plate 1 litre polo, apparently it’s a common issue with these models. I initially took to the local non VW garage, he couldn’t fix the issue, then he had to get hold of someone who had VW computer like the dealers.

So it was sorted straight on the spot. The above code also says that communications errors etc. so it was actually “Vacuum Sensor” that’s also related to Start/Stop, it was showing errors. Replaced the vacuum sensor and it worked. Will I have to say I was lucky the guy had the sensor at his garage. Hope this helps
