General issues/advice for 2007 VE Calais V

[Bromz93]

Hey all,

I'm new to this forum, and I'm just looking to get some advice/ costs of repairs/ease of doing myself.

I have owned said Calais for 3 months, and have extensive service history with receipts every 5-10k kms.

I have plugged in code reader and pulled following codes:

1. P0500- Speed Sensor A
2. P0521- Engine oil pressure sensor/switch range/performance.
3. Engine oil pressure sensor/switch low.

Further to this I have the ABS light on, and the check engine light (common with VEs I know), and contact dealer (X service, if it's a service it was only done 3000kms ago. I have tried to clear the service reminder, but it hasn't worked as it says to contact dealer).

I also have rattles around the suspension when going on bumpy roads, just wondering if that will be the bushes?

Also don't know if it will be a fuel sensor issue, but my distance to empty is well off. As 1/4 of a tank is 20kms.

Any help would be appreciated. Any rough prices to repair by myself( if easy enough) or even rough mechanic prices.

Thanks guys.

First stop is having a charge circuit test, a battery health test and a battery load test done. This can rule out a very simple cause of all manner of electrical gremlins.
