- No TDIs Currently, I have an R36 Corrado. I've had an ALH Corrado swap, AHU Corrado swap and 2003 TDI Jetta
Yes, but not as easily or successfully. The 3 main issues are: a graphic mismatch between B3 & B4 gauge faces, (2) mis-identified/incorrect LED labels on the front surround and (3) a 2nd LED and resistor pair must be added.Will a FULL DIGITAL cluster from a B3 Passat work for this? I found a full digital cluster from a 4 cyl gasser. The only problem with it is that it is in a automatic.
No different than using a manual cluster.How hard is it to convert a B4 Automatic VR6 cluster to work?
Yes.Can I swap parts from a B4 TDI NON MFA into a B4 NON TDI AUTO MFA?
Except for GPL and MIL, yes (on B4 clusters, GPL works).Will the MFA and Signal stocks from a B3 work in a B4?
If you're not concerened about maintaining 100% correct OE TDI graphics, this could be an easy conversion.Ok, I guess I am getting myself confused here.
I found a 1992/1993 B3 Sedan with a 4 cyl gas engine with MFA. It is a Automatic (auto selector in tach). It has a DIGITAL ODO and MFA in the fuel/temp. It looks like the B4 VR MFA cluster. There is no analog odo or trip.
So I guess my question should be:
1) Can I use this cluster in a B4?
2) Can I swap the tach from the B4 NON MFA Manual Cluster into the B3 Auto Tach location?
3) Add 2 LED's (1 for glow plugs and 1 for MIL)?
4) Change the graphics for the tach to represent the lower rpm range?
5) Signal and MFA stocks interchangeable for the B3 and B4?
6) Change surround to match the B4 LED's?
That looks correct for the air temp sensor.Ok, I think that I have all the parts needed. I have a couple of questions.
1) Is this wiring in the 1996 B4V Canadian Model? Or do I have to add it? (brown/white and white/red wires that originate from pins G1/2 and G2/2)
Unfortunately, no. The country code can be reprogrammed to US units but you cannot split out units between different cluster components.2) Can this cluster P/N 3A0 919 880H be converted to have a Metric ODO with a US MFA?
The oil sender should not be present. You shouldn't have to add any wiring. Just look for the unconnected single black wire with female connector near the oil filter/cooler adaptor. Install the sender in the unused, plugged port3) Oil sensor? is it all ready in the Canadian Version of the B4V? Do I have to add any wiring?
So they are terminated in the G* blocks, but may or may not have a connector (black 2 wire) attached?They should already be there but they may not be attached to a harness connector. Sometimes they are just 2 bare-ended wires.
The A3 conversion is very similar to the B4 but A3s are missing some additional wires & harness connector pins that must be added.
Missing A3 cluster & relay panel connector pins & wires between cluster and relay panel:
Missing cluster and ECM connector pins & wire between cluster and ECM:
- Cluster pin 6 - MFA controller switch - goes to pin 8 of the U2 connector on relay panel.
- Cluster pin 15 - MFA controller switch - goes to pin 4 of the U2 connector on relay panel.
- Cluster pin 17 - oil temp. sensor - goes to pin 1 of the U1 connector on relay panel.
- Cluster pin 19 - outside air temp. sensor - goes to pin 2 of the U1 connector on relay panel.
- Cluster pin 1 - outside air temp. sensor - goes to pin 7 of the U1 connector on relay panel.
Note that the above list does NOT include the missing 4-wire harness that runs between the MFA controller switch and relay panel, true also for B4s.
- Cluster pin 26 - Fuel consumption signal - which connects to ECM pin 9. This wire goes directly from cluster to ECM without passing through the relay panel.
There is an issue of a change in warning light circuitry configuration in, IIRC, '96, so a '96 or later MY VR6 cluster should be used.
Contact TDIClub member ChubsAuto or VWVortex member A3clusters to have your cluster reprogrammed to correct the tach reading (rather than the pulse frequency adaptor method described in post #1) and to reset odometer mileage to your current value.
No, you can't, but its not necessary.
As with the B4 cluster, you simply install your original TDI tach face plate on the VR6 cluster and have the cluster cylinder coding changed to match. You may be able to successfully transplant the entire TDI speedo module into the VR6 cluster and have it read correctly by having the impulse distance number recoded to match that of the TDI cluster, but it would be easier to just live with the VR6 speedo.
You may have to use an earlier GTI/GLI cluster that uses black instrumentation facing. I'm not sure what year they transitioned to silver facing or if silver and black were both available throughout the model/year range.
Speedo uses the VSS signal only, 4 or 6-cyl. is irrelevant.BUT A3cluster says he can't change the "impulse distance number." The VR6 speedo would not read correctly anyway with pulses from a four cylinder, would it?
