Looking for some informed opinions before I decide whether to keep throwing money at this or cut my losses. Currently at £500 spent
Problem:
- Car is going into limp mode, only on motorway type journeys, when I hit 2500-3000rpm and 55-60mph. Problem started 6 months ago
- Power drops suddenly, service light comes on
- No issues when pottering around town
- Turning ignition off and back on clears limp mode, but it returns again under load
- After a few weeks, constantly in limp mode, cant get over 3000rmp, feels like no power
- Has been in and out of garage all week
- DPF pressure sensor changed, dpf cleaned out, regen forced. Test drove, went into limp mode
- Changed boost pressure sensor (it was dirty looking inside), test drove, went into limp mode
- Changed cylinder Pressure glow plug 2, test drove, went into limp mode
- I gave garage list of extra items to check, but they cant find any issues
- intercooler boost pipes for cracks
- Exhaust gas sensor operational
- They said they do not know what the problem is, so I am here looking for some support and suggestions.
- P03A3 – Cylinder pressure sensor (cylinder 2) implausible
- P2453 / P2458 – DPF differential pressure related
- 2012 Vauxhall Insignia
- 2.0 CDTi diesel
- 115k miles
- Manual
- DPF equipped
Appreciate any advice, thank you
Chris
