Today I got a really rare car for our region - Audi A4 B5 2,8l MY2001, the NAR version. Problem is with combined oil level/temperature sensor. Sensor fault is displayed and VCDS confirms it. There was some probably cheap noname sensor fitted by another workshop. I have checked wiring to sensor, repaired some suspicious connections but without any results. I tried one new Hella made sensor and two used original ones - all the same. Unfortunately new OEM sensor is not in stock at local dealer.
But I can't believe that all 4 sensors are bad. Wiring is re-checked several times, I have even disconnected original signal wire from IPC T32a, pin 15 and fitted another connector for sensor, in short wires directly to input of IPC. All the same. I have seen in some VW models, that sensor fault for low oil level could not be reset, before IPC "see" than bonnet was opened and closed. At this car switch for opened bonnet was damaged by corrosion, but I fitted another wire directly to IPC input for bonnet switch (T32a, pin 25) to imitate bonnet opening/closing. But LCD in IPC did not show warning for opened bonnet.
We do not have NAR version cars in junkyards here, no way to get another used IPC for testing/replacement.
Do anyone here has similar experience with not working signal inputs for NAR Audi A4 IPC 8D0920980Q? Is it some common know fault four those clusters?

Hello,

We do not have NAR version cars in junkyards here, no way to get another used IPC for testing/replacement.
Do anyone here has similar experience with not working signal inputs for NAR Audi A4 IPC 8D0920980Q? Is it some common know fault four those clusters?

- Most failures I have seen on the older Audi clusters is the red led display that makes it not possible to read it.

- Have you tried to locate a company that can test and repair VAG clusters? Even if this is a cluster that was not available in your market, the internals should be very similar to your market clusters.

- Also in the past I would order parts for non NAR markets through online vendors/stores and auction websites when I could not source them locally, just a thought :)

Lastly, have you seen our Ross-Tech wiki page that has links to the Official Factory Repair Information? There maybe some addition information there, TSBs, etc...


Hope this helps,

drpeter

Thanks, Peter!
I'm doing some cluster repairs by myself (replacing and reprogramming processors and memory chips, replacing LCD's, replacing gauge motors etc.) ;)
Just haven't seen that kind of fault for VDO clusters before. And I always use to test everything possible around any electronic module to be for 100% sure that fault is inside module, before opening it and attempting to troubleshoot and repair internal circuits and components. And collect all possible information available.
So mainly I ask for other forum member experience here.
P.S. I'm not sure will Erwin give me info about NAR market vehicle. But haven't tried yet. From an alternative sources of information - no TPI for clusters with this partnumber. This is not that case where customer is ready to pay for almost everything to get his car in perfect working order. Unfortunately, a lot of times here, in Eastern Europe, we must repair things in some cheapest possible way, that is not the best way, of course...

Thanks, Peter!

Glad to help ... :)

- I would suggest to check www.PartsLink24.com

- There you can get actual parts and part number information by VIN number or make, model, year, etc.... It is a subscription based site and appears to be linked to the manufactures database, you can get PR codes there too, very useful website :).

Thanks, I have PL24 available. Only thing in this case - it does not decode exact parts, engine code, pr codes etc by VIN for this vehicle. For European market it is standard situation for VAG cars, older than MY 99-2000. (incorrect parts are not greyed out etc, for older cars PL24 is just copy of ETKA and user should determine the correct part by himself) Looks like the same for this NAR car MY2001. ...

Found, whats wrong with this cluster - SMD diode on PCB has an open circuit. No pre-voltage for oil level/temperature sensor input. Cluster works on table now, will test on car tomorrow ;)

BTW found some info missing in label file 8D0-920-xxx-17.lbl for those clusters. I found one similar cluster in junkyard, 8D0920980D, this is from NAR Audi S4, probably MY2000. My one is 8D0920980Q, NAR Audi A4, MY2001. Made maps from both.

Couple channels where I noticed some incomplete info:
- Adaption channel 04, Language. Not shown in drop-down list under adaptions. No pop-up balloon with possible values. Values are: 1-German, 2-English, 3-French, 4-Italian, 5-Spanish, 6-Portuguese, 8-Chinese.
- Adaption channel 18, Aux. Heater. Not shown in drop-down list under adaptions. No pop-up balloon with possible values. Values are: 0-Not Installed, 1-Installed, 2-Installed, heater switches off when ignition is switched off. This channel allows aux heater control functions via Highline cluster menu. P.S. Not tested by myself, no aux heater available.
Some more adaption channels are active/accessible, CH 61, for example, but they looks completely undocumented, no info in FSM, too.
Will send maps to support@ross-tech.com ;)
