P0257 Fault Code on 2002 Vauxhall Corsavan 1.7DTI (Isuzu) - Repair Cost and ECU Module Fix?
Hi everyone, I'm currently dealing with a P0257 fault code on my 2002 Vauxhall Corsavan 1.7DTI (Isuzu). This morning, while driving to work, the engine suddenly stalled at a traffic light and wouldn't restart. I called out the RAC who scanned the vehicle and confirmed the P0257 diagnostic code. After resetting the code, it returned immediately. The technician warned me that in worst-case scenarios, repairs could cost up to £1,500 — which is alarming given I only paid £1,400 for the car. I've seen listings on eBay for a 'Pump ECU Module' priced around £60, and some suggest it's a relatively straightforward swap. Could this be the actual cause? Are there any known solutions or common fixes for P0257 on this model? Is replacing the ECU module worth it, or is this likely to require more expensive repairs? Also, I've picked up two additional codes: P0704 and P0370. The RAC technician mentioned these are less critical. Any real-world experience with this issue on a 2002 Vauxhall Cors或1.7DTI? Any advice or troubleshooting steps would be greatly appreciated. Thanks in advance! P.S. I'm looking for cost-effective, reliable fixes to avoid major expenses.
