View Full Version : Software Update Trashes Infotainment Control Module 5F

Had the car in for its third service + MOT this week. Had a recall request from VW to update the infotainment software (kind of expected that). Later in the day I was advised that the software would not load and they needed a part which would arrive overnight, which it did. End of that day, call to say software still would not load and throwing large number of error codes. Next day advised that after lots of investigation and remote diagnostics by VW they have determined that the 5F control module is faulty and needs replacing, however there are none available in the whole of Europe and there is no expectation as to when one will become available. Fortunately I had arranged a loan car so am still mobile. However what totally shocked me was that the cost of this part, apparently warranty parts are priced on a cost + small percentage, was £3500! There would be labour for installing and programming on top of that.

What this got me thinking was that I am fortunate this failed while the car was still (just) in warranty, but if it had required replacing in say another 3 years time when the car was 6 years old, the cost of replacement would probably not be economic compared to the value of the car, resulting in a perfectly good car being scrapped. It would almost certainly be impossible to replace outside the dealership network as it would need the software downloading from VW in order to programme it for the car and no doubt it is a protected component as well. There is clearly a major downside to all the sophisticated systems the manufacturers are providing in new cars.

In all this I cannot fault the dealer or VW, they have been nothing but helpful and with VW having to pick up the cost of the loan car I am sure they will be keen to get this resolved asap.

Partly why I keep my 53-plate Touran running. No component protection, has a reasonable amount of safety equipment, AIUI all likely maintenance can be done via VCDS, still plays '80s NTWICM CD's just fine... When it dies I expect to find a later pre-CP something to nurse through its final years.

We had a Golf 8 tsi hybrid in for service yesterday and the tech said “the radio is asking for an update, shall I do it?”, I said NO! If it ain’t broke, don’t fix it.

I really don't get this software thing, are the manufactures not spending the time on developing them?
It is really bad with JLR bricking systems with simple updates.
One person on the FB said that the dealer procedure for a battery disconnect is to turn the ignition on first!?!??!?!? no wonder things are going **** up.

I work In R&D as a hardware engineer, and you cant get away from software. My habit, which people laugh at, is to always pause and let the software settle - and I seem to have less issues than others.

We had a test rig that gave a big prompt to the operator that said Finished, and we then had a spate of boards coming in with no pass result written to memory.
It turned out to be a super efficient operator swapping boards out the second he got the finished prompt. The test may have been finished but the rig was still writing Pass to the UUT.
I wonder if its a similar thing with software updates - finished updating but still in comms verifying checksum or similar?

VW's software division Cariad has for the second time in the four years since its creation carried out a "structural and personnel realignment", i.e. everyone got fired.

Remembering of course that original versions of the software in the Golf8, ID-3 and the current generation Audi A6/A7/A8 and Q7/Q8 all predate the formation of Cariad, and Cariad was set up to bring the software development back in house because of the issues with the third party developer. The issue with my car seems to be a hardware fault - hence the need to replace, whether already there or caused by an issue with the software update process is probably something we will never know the answer to.

I digress a bit, when i was in Tech we were told a story about a software engineer getting charged with manslaughter.
The legend goes that a robotic arm got stuck so the operator hit the stop button, and then went and cleared the obstruction.
After which the robotic arm continued up until the point in the software routine where the stop button had been pressed!!!

Part sourced and car returned yesterday and all seems well, although it is real pain having to go through the whole car set up process again as if it were a new car. Fingers crossed it is fixed. Glad I was not picking up the nearly £4k bill (parts plus labour) for the repair

Modern cars are ****… regulators, please stop this.
