Jetta 6 tdi ecu

[khotsonkadi95]

Good evening everyone. Compliments of the new year, I've been really struggling to get an ecu for my 2015 Jetta TDI 1.6. It uses the part number 03L906023SR seimen continental pr 2.1. I've been searching it all across the country with no luck. If anyone has the ECU can you please assist. It would be highly appreciated.

There is a used one for sale in Germany but it is about the same price as a new one. I had a look at your post on https://www.vwclub.co.za (https://www.vwclub.co.za/forum/viewtopic.php?f=91&t=222417) and it made me question the need for a new one as the symptoms are more like a fault with the key, reader coil or possibly the instrument panel. Your mechanic does know a new ECU is not plug and play doesn’t he? Which diagnostic fault code reading system is he using?

Which system is that, I don’t recognise it? Can you post a full vehicle scan in text? There is an error there which suggests the engine ECU has been remapped.

[khotsonkadi95]

The system is VVDI2.

The Unit has 1 DTCs

9456128 - Engine Control Module not Authorized

More like an immobiliser error to me, have you scanned the dash? Do you have a spare key?

[khotsonkadi95]

Hi yes the immobilizer blocked engine start(6260). Here are some of the other faults ECM incorrectly coded(9857).ECU incorrectly coded(11844). ECM INCORRECTLY CODED(6548)

I am struggling to make sense of those, you need to find someone who has full and registered VCDS so they can do a full scan and save the results so you can post it. Do you have a spare key?

[khotsonkadi95]

No I don't have a spare key I had to get an aftermarket key.

I can send you the diagnoses resultshttps://uploads.tapatalk-cdn.com/20210121/43a3feb1b5ec3d51718540170347c439.jpghttps://uploads.tapatalk-cdn.com/20210121/7556918665271f6ffab34f0e0cb2df93.jpghttps://uploads.tapatalk-cdn.com/20210121/8899b162c9828a76c1ed9e81b66ae176.jpghttps://uploads.tapatalk-cdn.com/20210121/f2563aba754d51818ea476e2da108e26.jpg

So you are only using an aftermarket key? Has this ever worked?

[khotsonkadi95]

It's cranks but doesn't start

Does it start and then immediately cut out?

[khotsonkadi95]

No it just cranks without starting.

You can hear that it wants to starts but doesn't

It sounds like the immobilser is doing its job, have you ever had this key work? Have you ever known the car to start?
