I know this has probably been discussed before but bear with me....

The oil pressure gauge works fine but the voltmeter doesn't and I think I've narrowed it down to the gauge itself so I'd like to fix it. I'd like to keep the oem look so no digital/led stuff. Can just the voltmeter be replaced? It is available separately? If not can they both be changed so they match? I know the voltmeter will be easy but what about the oil pressure as it needs 2 separate positive feeds it would seem. Do all oil pressure gauges have this? Thanks.

Hi,

Had exactly the same issue as you a while back. Thankfully on the 04 VXR is uses a standard voltage gauge setup for the volt meter. later cars used fancier dials hooked into the databus if I understand correctly.

The good news is that you can buy compatible generic dials for £20 or so - I bought a durite analogue one - and are easy to hook up with a couple of short adapter leads if you don't want to cut into the existing wiring and connector.

The bad news is that I haven't found any of similar design to the OEM ones. The durite one was cheap and does the job - but the gauge is a traditional across the top rather that along the side sweep design, and also had a black surround rather than silver. You also might not be able to use the metal attachment bracket with it.

As it happens I'm trying to replace the durite one now. Bought a digital one (which should be arriving shortly) with silver surround and pretty shallow so should allow the bracket to be used. I notice you said you don't want a digital one though.

If you want the oem look/style you may well have to get an actual OEM one. frown If you go aftermarket, any good 52mm dial that isn't too deep should do.

Given how widely the original one started reading, I'm not sure how accurate the oem oil pressure one is now either - but not sure how you would check that. Given it's driven off a sensor on the engine any replacement would have to work with the same specific voltage range, so don't know what I could replace that with.

A pure guess here, my old Dodge had a voltage regulator for the dash gauges(which was known for breaking). Are you only having probs with the one gauge?. Looking at the wiring diagram would tell you if our cars have a similar system

No voltage regulator that I'm aware of. I also tested the oem dial out of the car using a 12V power adapter and it was still way off - so definitely an issue with the dial and not the wiring in the car.

There is an adjustment screw accessible through a small hole in the side of the gauge but it doesn't vary things that much.

Everything was fine with a cheap replacement dial though.

OK thanks for the response. I'll try and replace the voltage one with a similar one if I can find it, I'm the same as you I think the gauge is faulty rather than the wiring. I'm just keen to keep the OEM look that's all....

I've been doing some digging, and the stock gauges are actually made by VDO.

They have analogue ones listed on their website which appear to have the same mounting and connector types as the stock ones.

Should be a drop in replacement? Just need to source a UK supplier. smile

Edit; They have their own shop smilehttp://www.vdoshop.co.uk/acatalog/Voltmeter.html

On the stock install the dials have two bolts attached to the rear, and the metal support bracket attaches to that. Given the position on the new dials if the bolts were fitted the gauge would need to be rotated 90 degrees to fit the bracket. I guess that's why they did sideways faceplates. smile
