TRAPPED INSIDE VW POLO

TRAPPED INSIDE VW POLO

Believe it or not, I got locked inside my VW Polo and couldn't get out. The self lock was activated, and me pulling at the door release lever just had no effect. The locking indicator pin surfaced from hiding put retracted when I released the door lever. For the sake of clarity, let me start at the beginning.  In a previous blog, I mentioned that when my VW Polo 2.0 Highline sedan was returned from its 90 000 Km service, it came back with a stripped nut  that tightens the earth terminal of the battery. I suspected that it was the cause of intermittent loss of power steering and I was going to get round to replacing it, but I just didn't have the time. Yep, procrastination is an evil that does get the better of all of us at one time or the other.

Anyway, getting locked inside my VW Polo on Saturday morning gave me a scare that I immediately went and replaced the entire terminal and not just the stripped nut. The previous evening, whilst driving home from movies, the dashboard lights on my VW Polo stopped working, it kinda just went dark. So when I arrived home, I started fiddling to determine why, and I discovered that the wipers and the indicators weren't working either. Must be a fuse I thought. So I went straight to the fuse box and whipped out  the scorecard. Seconds later I identified the fuse responsible for supplying the dashboard with power (marked with yellow arrow and see the powdery substance in fuse holder, it's most probably oxidation from condensation). I got out my multimeter and checked the 5A fuse (fuse 30) and as I suspected, it was open circuit, fused, blown. Oh crap, I didn't have a spare so the following morning, off I went to the auto spare to get a replacement.  It was rather hot so I opened my window about 10 cm before I took off. As I pulled away,  the  self  lock  engaged at the very moment I realized that I didn't  take my wallet. So I stopped, reversed back about the 100 meters I drove, switched off the engine pulled out the key, pulled the door handle and it wouldn’t  open. Pulling at the door release lever just raised the locking indicator pin put retracted when I released the door lever. I then reinserted the key, turned on the ignition, pressed the unlock button on the door, heard the door unlock, opened the door, jumped out, ran inside grabbed my wallet, got back into the Polo and off I went once again.

This time, I noticed that the auto lock engaged at about 40km ph. Thinking nothing of it, I arrived at the auto spares, switched off the engine, pulled out the key, pulled the door release lever and like before it wouldn't open.  And as before I reinserted the key turned on the ignition, pressed the door release yet nothing happened. I then realized that the ignition wasn’t on. So I attempted to start the engine and nothing happened. The battery terminal wasn't making contact, I came loose once again and the engine wouldn't start. By extension, there was also no power to the door electronics that operated the door. In desperation to get out, I even tried the fob remote unlock button even though I knew that without a battery connection the door electronics cannot open and neither power the motor that rolls down the electric windows. I was stuck inside. I figured if I could get my arm through the 10 cm opening, I could possibly open the door manually with the key. But the opening was too small or my arm too thick.  Now it was starting to get hot inside the Polo. My only other option was to ask a passer-by to unlock the door for me. So a few minutes later an elderly gentleman walked by, whom I alerted, and speaking through the window opening, and handing him the key   through the window opening, I asked him to unlock the door which he obligingly did.

With the door open, my mind was racing, what if the window wasn't slightly open, meaning I wouldn't have been able to pass the key to anyone to open the door. I would have been trapped inside and helpless. The escalating heat would have got the better of me. I probably would have had to kick-in the driver-door window since it's the only door that actually has a key receptacle, so that I could unlock it from the outside. This made me wonder what would happen if the battery gets damaged or destroyed in a collision and I was injured inside and not able to break the window. I know that in the event of a crash when the airbags pop, the on-board software is configured to automatically unlock the doors, but what if the supply voltage to the indicators gets shorted in a crash causing that fuse in question  also to blow. Clearly this is a hazard, and I would think a small sealed backup battery like those used for alarm systems fitted inside the cockpit under the dash or the consol would be a good idea. I think the brave among you should try to replicate this problem on your vehicles by removing the 5A fuse in question and disconnect the battery then assess whether or not this is acceptable design or a reason to get into Volkswagen's face about it. They are already going through the pressures of their emissions scandal, and it really isn't nice to kick a dog when it's down.

INTERNAL CONTROL MODULE MEMORY ERROR

INTERNAL CONTROL MODULE MEMORY ERROR

DTC error 65535 (Internal Control Module Memory Error) suggests a problem was caused  within the said module. However, Electronic Control Modules are generally fairly robust and are designed with a MTBF of 1 million hours. My experience with electronic repairs over the past 30 years does not confirm this since I have had tons of electronic components failing during this time that was'nt expected to fail for at least another 10 years. Be that as it may, an Internal Control Module Memory Error may not even be caused by the module, so it should be the last component to suspect and replace because they are normally not cheap. Firstly check the battery Supply Voltage  and verify that it is constantly about 12V or higher. Also make sure that the alternator is charging, since a faulty alternator can lead to a slowly discharging battery not able to supply the minimum voltage required by the module that is flagging the  65535. Next check to wiring harness to and from the "faulty" Control Module. Make certain that the module has a ground connection (earth). If  VCDS displays an unexpected result or displays that the controller refused the command, it is most likely due to the wiring. Under intermittent wiring conditions it is generally difficult ifnot possible  to clear a  65535 (00-10) or (35-00) or (35-10) or (37-10). Wiring harness and its connectors are prone to corrosion due to condensation especially in cold weather. If needs be, unplug the connector and clean them and if possible check the physical contact with an ohm meter (but disconnect the battery first). Any Internal Control Module Memory Error associated with the Power steering  and ABS are critical and should be attended to immediately. Internal Control Module Memory Error associated with Airbags should be treated with caution since interrogation of the airbag with a scan tool could inadvertently trigger the airbag or turn on the airbag light which can only be switched off by replacing the airbag module. As can be seen below, virtually every electronic module can be a victim of 65535 - Internal Control Module Memory Error and as far as I am concerned, it most unlikely electronic design and quality control  will permit such modules to be installed in production units. The lateral acceleration sensor tend to cause an 65535 airbag error, the vacuum hose inside the ECU taking pressure to the barometric sensor tends to cause a 65535 error in Jetta's, barometric sensor itself tends to cause 65535 in Skodas.  As a last resort try replacing the module concerned.

01044 - CONTROL MODULE INCORRECTLY CODED

CONTROL MODULE INCORRECTLY CODED

Since 1994 auto repairs has drastically changed, so much so that most cars cannot be repaired  without a diagnostic code tester. It is therefore advantages to invest in one of the hand held free standing devices or cable interfaces that plugs into a USB port of a laptop computer running the appropriate software to do the necessary. The best software to date for Vag cars is undoubtedly VCDS from Ross Tech. Their latest version is version 14. The software is absolutely free but the interface cable comes at a cost. It is a bit pricy but its a worthwhile investment since it entitles you to free updates for life. This interface cable has a built in PAL chip which doubles-up as a dongle containing the cable activation code. Even though there are several out-band 3rd party interface cables available on the market, none of them gives you the confidence that a VCDS HEX-CAN automotive diagnostic device, that is backed by a service company ready to help with any automotive queries, gives you. Bare in mind that this software has the ability to change the behaviour of the electronic control systems built into your car which can result resulting in catastrophic effects if not performed correctly. If you lack the competence or confidence to perform these operations, or even if you are unfamiliar with or the software, I urge you to refrain from changing anything and obtain an experts advice or assistance. Write down or print out all codes and settings so that it is easy to revert back to them.

Below are just a few of the faults that have popped-up on various vag cars over the past few years. Since the codes cover all Vag cars, the code "01044 - Control Module Incorrectly Coded" has occurred several thousand times in all makes and models of Vag cars, in all languages and countries throughout the world.

What I find most intriguing is that for most DTC codes, VW offers some sort of help by using words like "intermittent" " implausible" "short circuit" "limit exceeded", etc.. like these faults below, but the 01044 faulty code featured above offers absolutely none. However, I have included some data below that may be of some help. Should you find these codes helpful, all I ask is for you to like my site on G+1 , Facebook, Twitter, Pinterest, etc.

VW 9N CODES FOR:
CONTROL MODULE INCORRECTLY CODED

If  one of the following controllers is fitted in your car, try each of these codes individually  and you are guaranteed to solve your " Control Module incorrectly coded" problem, providing you have just changes the coding of one module or replaced only one module.  I need to stress as I have in a previous blog that every Control module that is fitted in your car has a prefered coding which is subject to the equipment it supervises. As such, its coding is stored as an onboard binary number, which in essence is the binary sum of the features for that specific module. Whereas the master ECU / Ctrl Head Dash  also stores an onboard binary number which in essence is the binary sum of all the Control Module's coding fitted in the car. This binary sum is called the checksum and any incorrectly coded  module will result in an erroneous checksum. If this is the case, the erroneous checksum is compared to a reference checksum also stored in the ECU module and any discrepancy could incapacitate your Volkswagen completely or present you with some peculiarities and error codes to match. Like the notorious 01044 control module incorrectly coded error. Checksum verification was adopted by BOSCH Motronic ECUs to validate its EPROM's stored data. So, it is wise not to change the coding or replace any control modules in your VW AUDI, SKODA or SEAT unless you are au fait with binary and hexadecimal number systems.
