Passat Immobilizer

Hi guys/gals.

We have a 1996-97 Mk3 Passat 18T at College I'm afraid its petrol but I would say the diesel versions would have the same problem. We've had it a couple of months and the battery is slowly going. Today the students were told to replace the battery with a new one which they did. Now the immobilizer light is flashing and it only runs for a couple of seconds which points to the immobilizer.

I've read everything in FQA now I'm presuming because of the year it has a immo 1 which wasn't released in the States before 1999 with a immobilizer. I've read that you can leave the key in the ignition for 10 minutes and it should correct the fault. Some say leave the ignition on for 10 minutes to correct the same problem. I've tried both options and the immobilizer is still flashing.

Any sugestions? ;)

Thanks for the links but I don't thing they are relavant. A lot say that immobilizers weren't fitted before 2000 well this is a UK model and it was. A lot talk about lost keys the need recoding we haven't lost it. I noticed today that the led on the remote doesn't light when you press either button. Autodata says it needs the dealer to recode if you change the battery in the remote.

I've emailed http://www.gendan.co.uk/ and http://www.ilexa.co.uk/ the English distributors to ask about cost and discount for the VCDS (VAG-COM) HEX-USB+CAN Interface Package. ;)

I do find the internet useful and useless sometimes as it's not always easy to know who knows what. There seems to be tons of rubbish info and you have to dig through it to find what you're after. Anyway I'll look out for a post when you get the car sorted.

I had a reply of Gendan today and they do a VCDS (VAG-COM) HEX-USB+CAN Power Bundle which includes LT Van adaptor, 2x2 Adaptor, USB Extension Cable and a carry case for £299.95. I'm trying to negotiate educational discount on this. I also had a reply of Ilexa and theirs was virtually the same but they charge £5 P&P.

They do the normal VCDS (VAG-COM) HEX-USB+CAN Interface Package for £262.95 with free delivery which I think I will buy shortly. Ross-Tech price is $349 - £222 which is a bit cheaper that Gendan but its UK and any problems its easier to contact them than sending it back to the States. ;)

Could you not say it's a vital piece of equipment and get the college to pay for it? Lol, I bet you couldn't.

I've stated its a useful peice of kit for any Audi, Seat, Skoda and VW cars but my programme manager is tight as a ducks backside, he's worried about paying £600 for a plasma cutter for the bodywork section.

I had an email back of Ilexa and they said they can give us a 20% educational discount off the price. Because PM doesn't want to spend any money I've opted for the basic VAG-COM/ VCDS Interface Package for £219.30 + VAT + £5.50 P&P and I presume the 20% discount. I also had an email back of Grendan after I asked if they could match the discount we were offered from Ilexa. They said
Ilexa don't actually sell official Ross-Tech interfaces - they build their own interfaces under license (or may have them built for them), and so they may be able to make them cheaper depending on the exchange rates to the country from which they source the hardware.
As we buy the official ones in from Ross-Tech in the USA, we are tied by the US Dollar exchange rates I'm afraid, so we cannot offer a discount on a single unit.

I checked the key the other day which the led doesn't light when you press the buttons which its probably the battery gone duff. I was talking to another technician about this problem he has a 2005 Seat Leon 2 he said bring it over and we will change the battery. Its the same CR2032 battery they use in the welding masks. We changed the battery and the led still didn't light up. He says you get the key working turn on the ignition and lock and unlock the doors that switches the immobilizer off, well it does on his Seat. With the buttons operating we can't try that. I bought a 6 pack of batteries this afternoon, 2 CR2032, 2 CR2025 and 2 CR2016 for 99p. I'm not sure that will do anything but at least we are starting with a new battery.

The http://www.ilexa.co.uk/ site has different sections that you have to use a username and password to access but I don't see anywhere to register. I asked them about this today we will have to see what they say. ;)

I fitted the new battery to the key today now the led lights and the central locking works again though one of the rear doors didn't lock or unlock. My friend at work said turn the ignition on and press the lock and unlock buttons and that should remove the immobilizer it didn't.

I emailed Ilexa yesterday to ask if they are authorized dealers for Ross-Tech after what Gedan said Derek's reply was
Our interfaces are definitely official Ross-Tech units, the only difference is that we have been with Ross-Tech for so many years, we're an OEM and purchase the interfaces as partially assembled units, and the final assembly is done here in the UK

There are no differences in the interfaces at that point other than the final assembly being done here. You get the same guarantee, same support from Ross-Tech and apart from our name on the label, they are the same thing. the advantage is you also get our support, and my technical knowledge built up over my working life as an auto electrician

If you have any doubt please contact Uwe Ross or anyone else at Ross-Tech and ask them.

We've been with them for nearly 9 years now, and I'm proud to say, I worked alongside Uwe Ross and other Ross-Tech staff on the VCDS stand at the Frankfurt Automechanika show in September this year. That I was invited to work alongside them on the stand as the UK representative says a lot about our relationship with them, and their product

So it was some sales crap from competitors.

Ilexa have a ilexa Onboard Diagnostics Forum. When I tried to register this morning it asks for a number of Ilexa. I had a message to phone Derek this morning so I phoned him back this afternoon. He explained his dealings with Ross-Tech virtually as per email. I asked him about the number to register for the forum. He said customers are informed about the forum and are given the reference number so we will have to wait until we buy the VCDS.

It also says they aren't taking new members at the moment. He said customers are allowed in. ;)

I was told today after a week we aren't buying VCDS for £170 + VAT (as we get the VAT back) they are going to ask students if they have one they can bring in, tight barstuards. Alright the car was given to use but thats not the piont its having the current equipment to do the job.

I'm still going to buy one for myself (a Christmas present for myself) and no they aren't borrowing it. Our programme manager used to be a motor vehicle lecturer 20 years ago but he's been doing a pen pushing job for the last 15 years nothing to do with motor vehicle, he only got this position because his job was up for redundancy. He's that way out of touch with things and he's in charge of the motor vehicle section. But thats typical of bosses they only hear want they want to hear. ;)

They are going to ask if any students have VCDS to fix it if they don't they are gloing to pay £50-£80 for VW to come out and fix it.

Ok I've ordered my own VCDS from

http://www.ilexa.co.uk/acatalog/vagcom.html

So I can now charge them £50 to get it fixed. ;)

Ok my VCDS arrived today. I've installed the software and plugged the lead in. Obviously I don't have the car in the home and I'm not going out to the freezing garage so it will have to wait for the weekend.

You can download the manual if you want too http://www.ross-tech.com/vcds/download/current.html

I might take it to work tomorrow and try it on the Passat. I will let you know if I succeed. ;)

Not much luck at the moment. It shows an error on 11 - Immobilizer: No responce from Controller. Derek says it could have the Immobilizer controller on the steering column or it could be in the instrument pack. I've had the column off and there is nothing connected so its probably in the instrument.

Thanks for asking.

I've got no further with it because it won't comunicate with the immobilizer or instruments it shows No responce from Controller on both. The thing is there is no control/instruction given to the students they are just told dismantle the brakes and are left to it, so things get broken or lost. The problem is when you have 15 lads in a workshop usually working in pairs thats 7 different jobs being undertaken so they can't watch everything. I've suggested they do it as a class exercise to you can what they are all doing but they won't do that. So there could be a problem that someone has unplugged or cut wires or what ever as they love to destroy everything.

The College still won't buy one so stuff them. ;)

We had a demo of the Bosch KTS 670 along with the Bosch Air Conditioner yesterday of Bosch. I thought while they were here lets see if they can get our Passat immobilizer reset?

They did a full scan and picked up loads of faults but none refered to the immobilizer. I said VCDS can't communicate with the immobilizer no responce from controller, the Bosch one wouldn't either. The KTS machine has built in wiring diagrams for all makes and models. We brought up the Passat diagrams and traced the wires. The immobilizer feed pin 7 of the DLC via fuse 32 (20 amp). There was a supply to that fuse so its lost the connection to the immobilizer in the instrument for some unknown reason.

Now we are thinking of buying the Bosch KTS 570 for the College. The 570 is exactly the same as the 670 but it runs of a computer/laptop via blue tooth dongle. Now the price of the 570 is £4,500 but because we are a College we get a better deal. Normally a garage would have to pay £600 each year for the Bosch updates and it has Autodata built in which cost £660 each year to renew the licence. We would get free updates of both softwares for life and the machine would cost us only £2,500.

Thats sounds like a great deal so I think we will be having one or even two of them at that price?
