Golf Mk4 TDI 115
Hi.

Suddenly my Golf 4 stopped starting, well, it would start and stop immediately. After asking and getting a little information I assumed it could be the immobilizer and decided to buy a VAG-COM. It has arrived yesterday and although I still do not control it, I have made my first scan.

The background is, a Golf 4 TDI 115 of 2.000, totally original, starts and stops immediately. The immobilizer warning light is as if it were dead, it does not come on at any time, not even to do the test when switching on the ignition.

I am attaching the VCDS log with the relevant errors for the topic.

As you can see, there is an error Start blocking by immobilizer in the engine, another of Communication interrupted intermittently with the control unit in the Panel and the same error in the CAN Bus.

Thanks.

.... ok, so the first issue, and it is a major one... that isn't legit VCDS. So until you resolve that, we are done here.

I do not understand why you say that. I have bought a VAG-COM 21.9 cable with the VCDS software legitimately. In addition to the verson 21.9 they have sent me the 19.6.2 because they have told me it is more compatible with my car, a Golf 4.

You are not using a legit Ross-Tech kit. Demand a full refund.

98 Jetta TDI AHU 1.9L (944 TDI swap in progress) I moved so now i got nothing but an AHU in a garage on a pallet.
To OP Who did you buy it from?
To rosstech vendor : why and how do you know that? Your not being helpful just rude. This beeb is trying and clearly is trying 100% to do the right thing.

The issue is yiu clearly have a fault with the security immobilizer.
You can either replace it or bypass it for now. There are many threads from faild or dying keys to the unit its self.
Bypass it for now so you can drive it. Order the parts to fix it. Depending on where in Spain you are... might be hard to get a legit cable .....

Yo, Mongler, chill. jef@rosstech isn't just a VCDS "vendor", he IS Ross-Tech. He knows that by reading data in the OP's scan. The OP has obviously been scammed by whoever he bought his cable from...

@MrFloppy looks like a module might be bringing your can network down so the ecu isn't able to communicate with the cluster. It's possible the sensor ring in the ign went bad or your key broke. Do you have a spare key? Easiest is just send the ECU in and have the immo deleted.

Does your dash light up properly? Can you do the test vcds procedure on it. Also if Jeff says you have a non genuine cable.... Did you buy it from a trusted vendor? Because the new software will work on the older cars. Just the software you were given may be hacked.

We at Ross-Tech pride ourselves on our customer service and I think our track record proves this. However, customer service is just that, service for our customers. As you might suspect, we are not obligated to help people using knock off versions of our product.

How do I know it is fake? Well, for one, the formatting and data not correct, not even close. Further, the person states:

In addition to the verson 21.9 they have sent me the 19.6.2 because they have told me it is more compatible with my car, a Golf 4.
None of our distributors publish or provide the English version of VCDS, it is only available via our Ross-Tecch web site. Outdated versions of VCDS are not available for download once a new version is make public. And the statement an outdated version of VCDS is "more compatible" is gibberish at best.

If you don't think he's a customer you're not obligated to reply either. Rude is rude bud.

Any other product is looking better and better.
I use obdeleven mostly. I managed to get the lifetime subscription. While not as indepth as vagcom. It's a good alternative. Just the support isn't there.
I have a genuine cable. Just was secondhand, and an older unlimited vin cable.

He's not being "rude" at all; just stating facts. The OP obviously thought that he had purchased a genuine Ross-Tech VCDS dongle, which is not the case. Jef was just explaining how he knew it was not the real deal.

When you research, build and develop a program that is known world wide as one of the best out there and then some chinese hack 2 bit programmer steals your work and sells it as legitimate, I wouldn’t be just rude I’d be mad. Not necessarily at the original poster who probably thought he had the real deal but at a government that allows this theft of intellectual property to happen without fear of consequences.
