Hi , please need help.
I have a mk6 rs2000 that will not start, the dash lights come on, but nothing on the last turn, the red light under the clock just flashes, no noise from anywhere, been told it is an ecu problem ,could this be right and if so what do i do, tried a search but no real answers.

Any help would be great.
Cheers........

 

Have you tried the spare key?

 

Not an ECU problem rather an immobilizer problem, as said try the other key as it may be the key is faulty or lost partnership.

Only got one key, not original one either, can you get new ones with the chip in ?. No idea where to start with the immobilizer any clues.

Cheers Paul....

 

Dealer?

How does it work, can you just take the key or do they need the car to match it up to work.


Paul.

 

Who says the key is defective? Could be the ring used to read the key or the immobilizer ecu as well.

 

The blue bit on the key has been messed with by someone, the immobilizer red light flashes all the time when trying to start the car, do not know what this ring to read the key is, is there any way of finding out wich it is without going to garage, any info is welcome, not good with electrics, confuses me .


Paul.

 

The ring is located around the ignition lock. It picks up the key number and transmit that number to the immobilizer. The immobilizer will check if the key is valid.
If you had a spare key it would be simple to find out what is wrong.
Since you don't have a spare key and you're also not good with electrics I would say, take it to the dealer.

 

The fact the LED is not extinguishing shows the immobilise to be armed hence why it will not start.

If someone has messed with the transponder the red or blue "Chip" in the key this will be the most likely reason.

There are different versions of the PATS system the older versions which yours maybe has a red key, this is known as the master and you need this in order to program other keys.

I suspect it is nothing more than the key that is wrong.

Thanks for the reply, it is a 1996 car, i only have one key and do not have the red master, would i have to go to ford for a new key, or would i have to get a new ecu with compatible key.

Cheers Paul.

 

I am not familer with the RS2000 so I can't say for sure, so the key you have has a blue transponder?

If it is the system I mentioned which would be around the time of the car then yes you need the red master key to program additional keys, there are of course ways around if this is not avaliable but most won't be able to do it as you need Ford software ETC to connect to ECU.

Looks like it is a trip to my local ford then to see what they can do, hope it is not to costly, is there no way round the immobilizer to just to turn the engine , would realy like to pin down my problem.

Paul.

 

There are ways around it but it's quite involved as immobilisers these days are quite good and part of the ECU.

Martin

 

Cheers Martin for all the info, will go to ford tommorow,will post on what they say. Have read other posts with same problem but there is never any answer to the problem, hopefully will sort it soon , probly need another mortgage at ford though.

Cheers Paul.

 

Thanks for all the help guys.
My Rs is now back up and running, it was the immobilizer, found out there was no chip in the key and the ring that picks up the signal had been moved to under the dash, called a auto locksmith and they made a new chip for me and checked the ecu as i did not have the master key to program a spare key, was alot cheaper than ford as well.

Well chuffed as i bought it as a none runner...........

 

No problem, glad it's running.
